Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 2, a schematic structural diagram of a lens assembly according to an embodiment of the present invention includes:
a lens barrel 1;
the N lenses 2 are fixed on the lens barrel 1, and N is greater than or equal to 1;
wherein, each lens 2 is correspondingly provided with a group of reinforcing rings 3 surrounding the edge of the lens; the reinforcing ring 3 is positioned in the lens assembly; the hardness of the reinforcing ring 3 is greater than the hardness of the lens 2 and greater than the hardness of the lens barrel 1.
Specifically, when assembling the lens assembly, the assembly height is determined by the AA process, and then the lens assembly is fixed inside the motor by glue. And then, fixing and attaching the motor on the bracket by using glue by adopting an AA (acrylic acid) process. The shrinkage or expansion effect generated in the glue curing process can generate pulling or extrusion stress on the lens barrel, and the inward transmission of the stress can cause the lens to deform slightly, thereby affecting the imaging quality.
This application sets up the great reinforcement ring of hardness 3 and protects every lens, all sets up a set of reinforcement ring 3 for every lens and encircles, comes resistance to stress, prevents effectively that stress from producing the deformation influence to the lens. The reinforcing ring 3 is made of a material having a relatively high hardness, such as a metal, e.g., copper, iron, or steel.
Preferably, the reinforcing ring 3 may be a continuous ring to ensure the stress resistance, but the reinforcing ring 3 may also be a ring formed by discontinuous hard segments, which is not limited herein.
In the implementation, the shape and position of the reinforcing ring can be various, and two are listed as the following examples:
first, the reinforcing ring 3 is located inside the lens barrel 1.
Specifically, as shown in fig. 2, the left side of fig. 2 is a sectional view of the lens assembly, and the right side is a perspective view of the reinforcing ring. The reinforcing rings 3 are arranged in the lens barrel 1, and the position of each reinforcing ring 3 corresponds to the position of one lens and is positioned at the edge of the lens to resist the stress of isolating and extruding or pulling the lens. Specifically, when the lens barrel 1 is manufactured by injection molding of a plastic material, the single-layer or multi-layer reinforcing ring fixed therein may be integrally injection molded. The structure of the reinforcing ring is a ring shape formed of a hard material as shown in the right side of fig. 2.
Second, the reinforcing ring 3 is located on the lens 2.
In this case, the reinforcing ring 3 may be disposed to cover the surface edge of the lens 2 (as shown in fig. 3 and 4), the reinforcing ring 3 may be disposed inside the lens 2 (as shown in fig. 5), and a portion of the reinforcing ring 3 may be disposed inside the lens 2 and another portion thereof may be disposed on the surface edge of the lens 2 (as shown in fig. 6), which is not limited herein.
In particular, the reinforcing ring 3 may comprise an application portion applied to the edge of the lens 2. The attaching portion is attached to any one or more of the following edges of the lens 2: side edges, upper surface edges, lower surface edges. For example: as shown in fig. 3, the attaching portions are attached to the side edges and the lower surface edge of the lens 2, and the corresponding reinforcing ring structure is shown on the right side of fig. 3. As shown in fig. 4, the attaching portions are attached to the side edges, the upper surface edges and the lower surface edges of the lens, and the corresponding reinforcing ring structure is shown on the right side of fig. 4. The reinforcing ring is attached to the edge of the upper surface or the edge of the lower surface, so that the lens 2 is supported, and the edge of the lens can be shielded by a light shielding sheet, so that light rays can penetrate through the area of the lens 2 which is not attached to the reinforcing ring 3.
In the implementation process, the reinforcing ring 3 including the attachment portion attached to the edge of the lens 2 may be attached to the lens 2, or the reinforcing ring 3 and the lens 2 may be integrally formed when the lens 2 is manufactured, which is not limited herein.
In particular, the reinforcing ring 3 may comprise an insert portion embedded in the lens 2. For example: as shown in fig. 5, the embedded portion of the reinforcing ring 3 is inserted into the inside of the lens 2 from the edge of the lens 2, and the corresponding reinforcing ring structure is shown on the right side of fig. 5. The reinforcing ring 3 is inserted into the lens 2 from the edge of the lens 2, so that the lens 2 is supported, and the edge of the lens can be shielded by replacing a light shielding sheet, so that light can penetrate through the area of the lens 2 without the reinforcing ring 3.
In a specific implementation process, the reinforcing ring 3 embedded in the lens 2 may be formed by integrally forming the reinforcing ring 3 and the lens 2 when the lens 2 is prepared, or the reinforcing ring 3 may be inserted and fixed after a groove is formed in the prepared lens 2, which is not limited herein.
Specifically, the reinforcing ring 3 may include both an attaching portion attached to the edge of the lens 2 and an inserting portion inserted into the lens 2. For example: as shown in fig. 6, the embedded portion of the reinforcing ring 3 is inserted into the lens 2 from the edge of the lens 2, and the attaching portion of the reinforcing ring 3 is attached to the side edge of the lens 2, but of course, the attaching portion may be attached to any one or more of the following edges of the lens 2: side edges, upper surface edges, lower surface edges. The corresponding reinforcing ring structure is shown on the right side of fig. 6. The embedded part of the reinforcing ring 3 is inserted into the lens 2 from the edge of the lens 2, not only supporting the lens 2, but also shielding the edge of the lens instead of the light shielding sheet, so that light can penetrate through the area of the lens 2 where the reinforcing ring 3 is not arranged.
In a specific implementation process, the reinforcing ring 3 including the attaching portion and the embedding portion may be formed by integrally forming the reinforcing ring 3 and the lens 2 when the lens 2 is manufactured, or the prepared lens 2 may be formed by forming a groove and then inserting and fixing the embedding portion of the reinforcing ring 3, which is not limited herein.
Preferably, as shown in fig. 6, the reinforcing ring 3 may further include a rib structure 31.
