The receptacles 101 may be made of a hard material that is relatively hard (relative to a soft material). Alternatively, the receptacle 101 may be formed of metal or PA-based plastic. The higher stereoplasm structure of hardness (i.e. holding portion 101) can guarantee that the whole lens holder has certain intensity to guarantee that the array module has the structural stability of preferred after the equipment is accomplished, promptly, be difficult for because receive external force and lead to the module structurally to produce deformation. Furthermore, the hard structure member can limit the possibility of outward expansion of the soft structure member (i.e., the deformation layer 102, which will be described in detail below), so that the respective optical axes of the plurality of camera modules are not easily deviated after being installed in the lens holder.

The receiving portions 101 may have a substantially rectangular shape, and the plurality of receiving portions 101 may be arranged in a line in the longitudinal direction or may be arranged in a line in the transverse direction. A light passing hole 103 may be provided on a top wall of the accommodating portion 101 for passing external light to the lens accommodated in the accommodating portion 101. The light passing hole 103 may have a substantially circular shape, but the present application is not limited thereto, and for example, the light passing hole 103 may also have a rectangular shape, a polygonal shape, an elliptical shape, or the like. Any structure that can allow external light to pass through the lens accommodated in the accommodating portion 101 may be used as the light passing hole 103.

The lens holder 100A may further include a deformation layer 102, and the deformation layer 102 is disposed on an inner wall of the at least one accommodating part 101. Alternatively, the deformable layer 102 may be disposed on the sidewalls as well as the top wall of the receptacle 101. The deformable layer 102 may be made of a soft material having a relatively low hardness (relative to the hard material). Alternatively, the morphable layer 102 may be formed from at least one of a TPU material, a PTE material, or a silicone material. The soft structure (i.e., the deformation layer 102) has a certain deformation capability, and in the process of installing the camera module, the soft structure will generate a certain deformation, and a certain elastic force is provided between the soft structure and the camera module, so that a certain friction force is generated between the soft structure and the camera module, and the camera module can be directly clamped into the inner space of the lens holder and can be fixed in the lens holder. In an exemplary embodiment, the image pickup module may be an AF module with a motor (auto focus module), or may be an FF module without a motor (fixed focus module).

In the present embodiment, the variable layer 102 is provided on the inner wall of each of the two accommodating portions 101. And in each receptacle 101, a deformable layer 102 is provided on the side walls as well as the top wall. On the inner wall of each receptacle 101, a plurality of grooves 104 may be provided. Each groove 104 may extend in a vertical direction and have a generally rectangular shape. The plurality of grooves 104 may be symmetrically distributed in the receiving portion 101. Accordingly, the deformation layer 102 has a plurality of first protruding structures 105, and the plurality of first protruding structures 105 are disposed on the side of the deformation layer 102 that meets the accommodating portion 101. The plurality of first protrusion structures 105 are respectively matched with the corresponding grooves 104 of the plurality of grooves 104, i.e., each first protrusion structure 105 can be fitted into the corresponding groove 104. In an exemplary embodiment, six grooves 104 may be provided in each receptacle 101. Accordingly, the number of the first protrusion structures 105 in each accommodating portion 101 may also be six, but the present application is not limited thereto. It is noted that any number of grooves 104 may be provided depending on the size and specific configuration of the receptacles 101.

The first protrusion structure 105 of the deformation layer 102 is embedded into the groove 104 of the accommodating part 101, so that the combination degree between the accommodating part 101 and the deformation layer 102 can be increased, thereby being beneficial to improving the overall strength of the lens holder and being beneficial to ensuring that the array module is not easy to fall off after being assembled. In addition, the symmetry setting of recess 104 is favorable to guaranteeing the symmetry of structure, is favorable to making soft structure's deformation even to be favorable to guaranteeing the depth of parallelism of a plurality of module optical axes of making a video recording in the array module.

In an exemplary embodiment, the deformation layer 102 may further have a plurality of second protrusion structures 106, and the plurality of second protrusion structures 106 are disposed on an inner wall of the deformation layer 102. The plurality of second protrusion structures 106 are symmetrically distributed on the inner wall of the deformation layer 102. Alternatively, a plurality of second bump structures 106 may be provided corresponding to the plurality of first bump structures 105. The space that soft structure plane part encloses is close with the size of the module of making a video recording, and perhaps the size of the through-hole that forms slightly is less than the module size, sets up protruding structure 106 and is favorable to the card and makes a video recording the module, increases the bonding strength of the module of making a video recording and support. Alternatively, the height of the raised structures 106 may be less than or equal to 0.50 mm, e.g., less than or equal to 0.40mm, less than or equal to 0.30mm, less than or equal to 0.20mm, or less than or equal to 0.10 mm.

Fig. 2 schematically illustrates a perspective view of a lens holder 100B according to an exemplary embodiment. For the sake of brevity, a description of portions similar to those of the lens holder 100A shown in fig. 1 will be omitted below.

As shown in fig. 2, the lens holder 100B may include two receiving portions 101a and 101B, and each of the receiving portions 101a and 101B may be configured to receive a lens (not shown) and may have a light passing hole 103 for passing external light to the lens. The lens holder 100A may further include a deformation layer 102, and the deformation layer 102 is disposed on the inner walls of the accommodating portions 101a and 101 b. Wherein the receiving portion 101 may be made of a hard material having a relatively high hardness (relative to a soft material). The deformable layer 102 may be made of a soft material having a relatively low hardness (relative to the hard material).

In the present embodiment, the variable layer 102 is provided on the inner wall of each of the two accommodating portions 101. However, in the second accommodating portion 101b, the deformation layer 102 is provided on the side wall and the top wall of the second accommodating portion 101 b; in the first accommodating portion 101a, the deformable layer 102 is provided only on the side wall of the first accommodating portion 101 a. That is, the lens holder 100B shown in fig. 2 is different from the lens holder 100A shown in fig. 1 in that the deformation layer 102 is not provided on the top wall of the first accommodation layer 101.

Fig. 3 schematically illustrates a perspective view of a lens holder 100C according to an exemplary embodiment. For the sake of brevity, a description of portions similar to those of the lens holder 100A shown in fig. 1 will be omitted below.

Referring to fig. 3, the lens holder 100C of the present embodiment may include two accommodating portions 101. On the inner wall of the first accommodating portion 101a, a variable layer 102 is provided. The deformation layer 102 is not disposed in the second accommodating part 101b, and the second accommodating part 101b has an open top end structure. That is, the second accommodating portion 101b is formed as a through hole surrounded by a four-sided hard material as a whole. The open top structure may correspond to a clear aperture. Wherein the receiving portion 101 may be made of a hard material having a relatively high hardness (relative to a soft material). The deformable layer 102 may be made of a soft material having a relatively low hardness (relative to the hard material).

The first accommodating portion 101a according to the present example is configured to accommodate a sub-camera module, which is engaged with a soft structure and mounted in a lens holder. Fix through using soft structure spare block, conveniently disassemble and adjust the position.

The structure of the second accommodating portion 101b according to the present example can be used to accommodate a main camera module, which is generally an AF module with a motor, having a large volume and weight. In addition, the main camera module generally has a high module height, and therefore the second accommodating portion 101b may be configured to have an open top end structure, which is advantageous for reducing the overall height of the array module.

For the lens module with larger mass, the lens module is arranged in the accommodating part formed by the hard structural member, which is favorable for providing enough supporting force for the lens module, thereby being favorable for ensuring the relative relation between the optical axis of the lens module and other modules or a lens bracket. Therefore, the main shooting module in the array module is fixed by adopting a hard structural member and carrying out a conventional glue dispensing manner.

The lens holder 100C shown in fig. 3 combines the accommodating portion made of hard material and the accommodating portion with the deformable layer in consideration of the large volume and weight of the main camera lens, and not only can provide sufficient supporting force for the lens with large mass, such as the main camera module, but also can simultaneously achieve the beneficial effects of facilitating the disassembly of the sub camera module and the adjustment of the position of the sub camera module, thereby facilitating the improvement of the whole optical axis parallelism and the assembly precision of the array module.

Fig. 4 schematically illustrates a cross-sectional view of a lens holder 100D according to an exemplary embodiment; fig. 5 schematically illustrates a cross-sectional view of a lens holder 100E according to another exemplary embodiment.

In an exemplary embodiment, the bottom end surface of the receiving portion may protrude with respect to the bottom end surface of the deformation layer. That is, the bottom end surface of the deformation layer may be lower than the bottom end surface of the receiving portion. As shown in fig. 4, the bottom end surface 1021 of the deformation layer may be formed as an inclined surface, and the bottom end surface 1021 of the deformation layer may be disposed lower than the bottom end surface 1011 of the accommodating portion, i.e., a step structure may be formed between the bottom end surface 1021 of the deformation layer and the bottom end surface 1011 of the accommodating portion. Alternatively, the bottom end surface of the deformation layer may be formed as a flat surface, or may be formed as a slope or a sloped arc surface, but the present application is not limited thereto.

In an exemplary embodiment, the bottom end surface of the deformation layer and the bottom end surface of the receiving portion may together form a slope. As shown in fig. 5, the bottom end surface 1021 of the deformation layer is formed as a slope, while the bottom end surface 1011 of the receiving portion is formed as a slope matching the slope of the bottom end surface 1021 of the deformation layer. At this time, the bottom end surface 1021 of the deformation layer and the bottom end surface 1011 of the receiving portion have the same slope.

When the accommodating part does not have a deformation layer, the bottom end surface of the accommodating part can be directly arranged to be an inclined surface or an inclined arc surface.

The arrangement of forming a step structure between the accommodating portion and the deformation layer, or forming the bottom end surface of the accommodating portion and the bottom end surface of the deformation layer as, for example, slopes, or forming the bottom end surface of the accommodating portion as, for example, a slope, facilitates the installation of the camera module in the bottom of the lens holder, which facilitates the installation of the camera module into the lens holder through the guidance of the opening.

On the other hand, after the camera module is installed in the lens holder, as an optional mode, the relative position relationship between the module and the lens holder can be further fixed by arranging glue at the bottom and solidifying the glue, and the structural arrangement is used as the position for arranging the glue, so that the glue can be effectively prevented from overflowing.

Fig. 6 schematically illustrates a perspective view of a lens holder 100F according to an exemplary embodiment. For the sake of brevity, a description of portions similar to those of the lens holder 100C shown in fig. 3 will be omitted below.

Referring to fig. 6, the lens holder 100F of the present embodiment may include two accommodating portions 101. On the inner wall of the first accommodating portion 101a, a variable layer 102 is provided. The deformation layer 102 is not disposed in the second accommodating part 101b, and the second accommodating part 101b has an open top end structure. That is, the second accommodating portion 101b is formed as a through hole surrounded by a four-sided hard material as a whole. The open top structure may correspond to a clear aperture. Wherein the receiving portion 101 may be made of a hard material having a relatively high hardness (relative to a soft material). The deformable layer 102 may be made of a soft material having a relatively low hardness (relative to the hard material).

The lens holder 100F shown in fig. 6 is different from the lens holder 100C shown in fig. 3 in that the side wall of the accommodating portion in fig. 6 may have at least one notch at the bottom end. For example, a first receptacle 101a can have a first recess 1012 and a second receptacle 101b can have a second recess 1013. The first notch 1012 is provided at the bottom end of the side wall of the first receptacle 101a in the lateral direction, and the second notch 1013 is provided at the bottom end of the side wall of the second receptacle 101b in the longitudinal direction. The design of the recess structure is such that the connecting strap of the camera module can be guided out of the receiving portion through the recess structure when the camera module is mounted in the receiving portion. It is noted that the specific configuration of the notches is not limited by the shape shown in the figures, the orientation of the notches depends on the structural design of the module, and the directional relationship between the first notch 1012 and the second notch 1013 is also determined by the structural design of the module. In other words, the first and second recesses 1012, 1013 may both be disposed in the longitudinal direction, or the first and second recesses 1012, 1013 may both be disposed in the lateral direction, or one of the first and second recesses 1012, 1013 may be disposed in the longitudinal direction and the other may be disposed in the lateral direction.

The lens holder provided by the application can have at least one of the following beneficial effects: the imaging quality of the array module is improved; the assembly precision of the relative position between the modules in the array module is ensured; reducing the offset between the optical axes in the array module; the difficulty of repairing and disassembling the array module is reduced; the reliability of the array module is improved; and protecting the monomer module.

Another aspect of the present application also provides a method of manufacturing the lens holder as described above. The manufacturing method of the lens bracket mainly comprises the step of forming by means of double-color injection molding or secondary injection molding.

Fig. 7 schematically illustrates a block diagram of a method of manufacturing a lens holder according to an exemplary embodiment; fig. 8 schematically illustrates a block diagram of a method of manufacturing a lens holder according to another exemplary embodiment.

Referring to fig. 7, in step S701, a hard material is injection-molded into a mold to form at least two accommodating portions, each accommodating portion for accommodating a lens and having a light passing hole for passing external light to the lens. In step S702, a soft material is injected into a mold to form a deformation layer on an inner wall of at least one receiving part.

In the manufacturing method shown in fig. 7, the hard material and the soft material are subjected to injection molding by the same set of mold and a special two-color injection molding machine. In the whole injection molding process, the hard structural part is molded by injection molding of the hard material, then the hard structural part is not demolded, and the soft structural part is molded by injection molding of the soft material directly after the mold is rotated.

Referring to fig. 8, in step S801, a hard material is injection-molded into a first mold to form at least two accommodating portions, each accommodating portion for accommodating a lens and having a light passing hole for passing external light to the lens. In step S802, a soft material is injection molded into the second mold to form a deformation layer on an inner wall of the at least one receptacle.

In the manufacturing method shown in fig. 8, two sets of molds are used for the hard material and the soft material and injection molding can be performed using a common injection molding machine. The two times of injection molding can be completed by the same injection molding machine or two injection molding machines respectively so as to improve the efficiency. In the whole injection molding process, the hard structural part is molded through the first mold, and then the molded hard structural part is placed in the second mold, and the soft structural part is molded on the second mold. It should be noted that, when the hard structural member is made of metal, the metal may be formed first by other metal forming processes, and then the soft structural member is formed by using a mold, and the forming manner of the hard structural member may be mold forming, die casting forming, or the like.

The application also provides an assembling method of the lens bracket and the array module.

The lens holder includes a plurality of accommodating portions, so that the number of the camera modules forming the array module can be multiple. The matching method of the array module can include one of the following:

2) the camera module comprises a 3D module of a receiving end and a transmitting end, or a combination of the 3D module and a conventional camera module; and

3) the combination of the mobile phone front-end ambient light sensor, the distance sensor and the like and the camera module or the 3D module.

According to an exemplary embodiment, the method for assembling the lens holder and the array module may be: firstly, preparing a lens bracket with each accommodating part provided with a soft structural part; installing each camera module into the corresponding accommodating part of the lens bracket; and testing the parallelism of the optical axis, detecting the quality of the array module, obtaining a finished product of the array module if the test is passed, or repairing the array module if the test is not passed.

The advantage of this kind of mode lies in not only possessing the advantage of easily reprocessing in the assembly process, can also further fasten camera module and lens holder through the point glue. Particularly, before the solidification is glued to the point, the module of making a video recording has been fixed through the frictional force of soft structure spare and the elastic deformation ability of certain limit for the module of making a video recording and lens holder have relatively fixed location, thereby can measure the optical axis depth of parallelism of equipment. At this time, if the measurement error is large, the camera module is fixed only by using the soft structural member, so that the camera module is easy to repair. If the optical axis parallelism test passes, can further fix the fixed intensity between reinforcing module of making a video recording and the lens holder through the point. In the whole assembling method, the soft structural member is arranged as a preassembly step, so that the assembling precision and the finished product yield of the lens holder are greatly improved.

In the assembling method, the top end face of the lens holder is provided with the through hole baffle plate made of soft materials, so that a limit can be provided for the module in the mounting process, the through hole baffle plate is matched with the soft materials on the peripheral side, and the module can be mounted at a set position.
