DETAILED DESCRIPTION

[0024] In order to make the technical purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0026] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0027] The embodiment of the utility model provides an anti-impact lens protection structure 100 .

[0028] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, the anti-collision lens protection structure 100 includes an elastic member 120 and a protection shell 130, wherein the elastic member 120 includes a first abutting portion 121, a connecting portion 122 and at least two second abutting portions 123;

[0029] The second abutting portion 123 is connected to the first abutting portion 121 through the connecting portion 122. There is a gap 120a between the second abutting portion 123 and the first abutting portion 121. The second abutting portion approaches the first abutting portion 121 through its own elastic deformation and is fixedly mounted on the lens 20.

[0030] The first abutting portion 121 is in a closed ring shape. The protection shell 130 is sleeved on the outer circumference of the first abutting portion 121 and fixed relative to the first abutting portion 121 .

[0031] It is understandable that in the technical solution of the present utility model, by providing the elastic member 120 and the protective shell 130, the elastic member 120 is mounted and fixed on the lens 20, and the protective shell 130 is sleeved and fixed on the outer periphery of the first abutting portion 121. When the protective shell 130 is impacted, since the second abutting portion 123 can produce elastic deformation, the protective shell 130 drives the first abutting portion 121 to elastically deform in a direction close to the second abutting portion 123, providing a buffer space for the protective shell 130 after the impact, avoiding direct impact on the lens 20, and reducing the risk of damage to the lens 20 due to the impact.

[0032] Please continue reading Figure 2 In a specific embodiment, the elastic member 120 further includes a protrusion 124 disposed toward the lens 20, the protrusion 124 is connected to the second abutting portion 123, and is located at an end away from the connecting portion 122. It is understandable that when the protective housing 130 is impacted, the protrusion 124 can absorb part of the impact force through elastic characteristics, thereby reducing the impact on the lens 20; and the protrusion 124 strengthens the fixation with the lens 20, further preventing the lens 20 from being damaged.

[0033] In one embodiment, the number of the connecting portions 122 corresponds to the number of the second abutting portions 123. It is understandable that the number of the connecting portions 122 corresponds to the number of the second abutting portions 123, which increases the elastic deformation capacity of the second abutting portions 123 and reduces the risk of damaging the second abutting portions 123 due to indirect impact.

[0034] See also Figure 3 In a specific embodiment, the connecting portion 122 includes a first connecting position 1221 and a second connecting position 1222, wherein the first connecting position 1221 is arranged along the first direction V1 and connected to the first abutting portion 121; the second connecting position 1222 is arranged along the second direction V2, one end of the second connecting position 1222 is connected to the second abutting portion 123, and the other end is connected to the second connecting position 1222; wherein the distance between the second connecting position 1222 and the first abutting portion 121 is greater than the distance between the second abutting portion 123 and the first abutting portion 121, so as to form the gap 120a whose opening distance is smaller than the internal distance. Specifically, as Figure 3 As shown, the side of the gap 120a away from the first connection position 1221 is the opening of the gap 120a, and the side close to the first connection position 1221 is the inside of the gap 120a. It can be understood that when the internal spacing of the gap 120a is greater than the opening spacing, the space in which the connecting portion 122 can deform becomes larger. When the second abutting portion 123 undergoes elastic deformation, the second abutting portion 123 can drive the connecting portion 122 to deform, and the deformation space of the connecting portion 122 becomes larger, reducing the risk of easy damage to the connecting portion 122 and improving the stability and fit of the entire structure.

[0035] It should also be noted that the connecting portion 122 usually does not contact the lens 20 when in a deformed state.

[0036] Optionally, in order to reduce processing costs, the protective shell 130 and the first abutting portion 121 are integrally formed.

[0037] See also Figure 3In one embodiment, the protective shell 130 and the elastic member 120 are formed separately. A first matching portion 125 and a limiting portion 126 are also provided on the outer periphery of the first abutting portion 121; a second matching portion 131 is provided at one end of the protective shell 130, and the first matching portion 125 and the second matching portion 131 are snap-fitted, and the first matching portion 125 and the limiting portion 126 are used for axial limiting of the protective shell 130. It can be understood that the protective shell 130 is fixedly connected to the first abutting portion 121 through the first matching portion 125 and the limiting portion 126. When the first matching portion 125 and the second matching portion 131 are loosely matched, the protective shell 130 can be separated from the first abutting member in a direction away from the limiting portion 126.

[0038] Please continue reading Figure 3 In one embodiment, a secondary housing 132 is further provided at one end of the protective housing 130 away from the second mating portion 131, and the secondary housing 132 is embedded in the protective housing 130 and threadedly connected to the protective housing 130. It can be understood that the provision of the secondary housing 132 serves to lengthen the protective housing 130, so as to expand the protection range of the lens 20.

[0039] In one embodiment, a lens protection film 133 is disposed in the auxiliary housing 132 , and the lens protection film 133 is used to isolate pollution and prevent the photographed object from contaminating the lens 20 .

[0040] See also Figure 2 In a preferred embodiment, the elastic member 120 further includes a dustproof portion 127 connected to the first abutting portion 121, the dustproof portion 127 is annular, located above the gap 120a, and spaced apart from the lens 20. It can be understood that the dustproof portion 127 is provided to prevent dust or impurities from falling into the gap 120a, so as to reduce the accumulation of pollutants inside the gap 120a.

[0041] In a preferred embodiment, the elastic member 120 is made of plastic, and the protective housing 130 is made of metal. It is understandable that the plastic material has good elasticity and can effectively reduce the impact of the lens 20. The metal material has higher durability and pressure resistance, and this combination can provide more effective protection for the lens 20.

[0042] On the other hand, plastic material generally has good insulation performance, which helps to reduce the impact of static electricity and magnetic fields on the lens 20, and reduce the interference of static electricity on the imaging of the lens 20. In addition, the manufacturing process of plastic material is relatively short, which can bring certain cost advantages.

[0043] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
