A transition part 15 is arranged between the first protruding part 12 and the first inner surface 16, the surface of the first protruding part 12 is a first arc surface 123, the surface of the transition part 15 is a second arc surface 151, and the first arc surface 123 and the second arc surface 151 are circumscribed, so that the structure of the transparent cover 10 is more attractive.

Preferably, the inner surface of the transparent cover 10 is provided with a first boss 12, and the first connection hole 121 is provided on the first boss 12, the first connection hole 121 being located in the first installation space 13. The advantage of the present embodiment in which the first boss 12 is provided on the inner surface of the transparent cover 10 is that: the transparent cover 10 of the present embodiment occupies a small space and is beautiful as compared with the case where the first boss 12 is provided outside the transparent cover 10. The volume of the first boss 12 is such that normal imaging of the lens 61 of the camera is not affected.

The main body 102 and the second connection 103 form side portions, and preferably the number of the first protrusions 12 of the present embodiment is 4, and each first protrusion 12 is disposed at a position where the side portion interfaces with the first connection 101.

Preferably, the center line of the first connection hole 121 is parallel to the center line of the first open end 131, so that the structure of the transparent cover 10 is more beautiful.

In order to improve the connection reliability of the transparent cover 10 and the case 30, the first connection hole 121 needs to be spaced apart from the first outer edge 111 by a suitable distance, and since the transparent cover 10 has a cambered surface structure, the greater the distance between the first connection hole 121 and the first outer edge 111, the greater the length of the first connection hole 121, the greater the length of the first connection member 20 needed, and the higher the cost of the first connection member 20. As shown in fig. 9, the first connecting bore 121 preferably includes a first bore section 1211 and a second bore section 1212, the second bore section 1212 extending from the first outer surface 11 toward the first bore section 1211, and the second bore section 1212 communicating with the first bore section 1211. The cross-section of the first bore segment 1211 has a smaller area than the cross-section of the second bore segment 1212, where cross-section refers to a plane perpendicular to the centerline of the first connecting bore 121. The first connector 20 connects the first bore section 1211 and the second connector bore 321. The second bore section 1212 is sized to be traversed by the first connector 20. In this embodiment, the first connecting hole 121 is divided into a first hole section 1211 and a second hole section 1212, and the second hole section 1212 is used for the first connecting piece 20 to pass through, and the first hole section 1211 is a hole actually matched with the first connecting piece 20, so that the length of the first connecting piece 20 can be set shorter, which is beneficial to saving the cost of the first connecting piece 20. The second hole segment 1212 also serves as a shield for the first connector 20, which is advantageous for improving the aesthetics of the transparent cover 10. The depth of the first bore section 1211 may be 2 millimeters. The diameter of the first bore section 1211 may be 1.5 millimeters. The second bore section 1212 may have a diameter of 3.25 millimeters. The first connector 20 may be a screw, the first connector 20 comprising a first threaded section 21 and a first head 22, the second bore section 1212 being accessible by the first head 22. The first bore section 1211 is capable of being accessed by the first threaded section 21.

The transparent cover 10 has a longitudinal direction and a width direction, and the two main body portions 102 are distributed along the longitudinal direction of the transparent cover 10. The direction perpendicular to the longitudinal direction of the transparent cover 10 is the width direction of the transparent cover 10. The plane passing through the center of symmetry of the transparent cover 10 and parallel to the longitudinal direction of the transparent cover 10 is a first cross section, and the transparent cover 10 cut by the first cross section is a first pattern. As shown in fig. 11, the design process of the first pattern is as follows: the point O is used as a circle center to form a circle with the radius of 33 mm, and the distance between the two circle centers O can be 72.36 mm. The angle between OA and OB may be 84.14 degrees. Wherein OA is perpendicular to AA. The CC has a length of 139.93 mm.

As shown in fig. 12, the bottom view of the transparent cover 10 is shown in fig. 12, and the end surface of the transparent cover 10 is a second pattern, and the design process of the second pattern is as follows: points D and E are center points of the first connection hole 121, through which the center line of the first connection hole 121 passes. Two circular arcs with different diameters are made by taking H as the center of a circle to form an inner circular arc line and an outer circular arc line of the second connecting part 103. The included angle between HD and HE is an obtuse angle, which may be 161 degrees. HD and HE may be 28.8 millimeters in length.

As shown in fig. 13, the structural design of one of the first bosses 12 in the second pattern is as follows: the circle with the radius of 6.25 mm is centered on the point D, and the circle where the circular arc line of the first convex portion 12 in the second pattern is located is obtained. The difference between the inner arc line and the outer arc line of the second connection part 103 is 3 mm. The outer arc of the second connecting portion 103 is shifted inward by 4.5 mm to obtain an auxiliary line, and two circles G with a radius of 4 mm are made on the auxiliary line, and the circles G are tangent to the circle D. The circle G intersects the circle D and the inner arc line of the second connecting portion 103, and forms a continuous curve.

The foregoing embodiments of the present invention mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in consideration of brevity of line text, no further description is given here.

The above is only an example of the present invention and is not limited to the present invention, and various modifications and variations can be made to the present invention by those skilled in the art.
