Thus, the housing has at least one of the following advantages: the first cover plate is made of a material with high toughness, the stress required in the forming process and the polishing process is small, the generation of scraps can be effectively avoided, the material of the shell body is not limited, namely the material of the shell body is selected more widely, the diversification of the shell is facilitated, the quantitative production is easy to realize, and the productivity is increased; the first cover plate is made of a material with high toughness, so that the generation of cracks in falling can be effectively relieved(ii) a The material of the first cover plate meets the performance requirement required by the laser sensor, and the laser sensor can be well used; compared with glass, the acrylic plastic has lower cost and can reduce the cost of the shell.
This application is through improving the material in the first through-hole that bears laser sensor, and is concrete, adopt the yakeli plastic to form first apron, because first apron area is less, and first apron needs to realize interference fit with first through-hole, adopt the yakeli plastic to form first apron, the yakeli plastic has stronger toughness, extrude first apron, so that form interference fit between first apron and the casing body when, because the required stress of yakeli plastic is less, thereby in extrusion process, can effectively avoid clastic production, and in follow-up polishing process, also can effectively avoid clastic production, avoid the preparation process to lead to the fact adverse effect to the luminousness and the roughness of first apron.

the type of structure of the housing body is not particularly limited, and those skilled in the art can design the housing body according to the specific situation. For example, the housing body 100 may have a two-dimensional planar structure, or a three-dimensional curved structure, or a structure in which the main body is a plane side wall with an arc surface.
In some examples of the present application, when the first cover plate 11 is composed of acryl plastic satisfying the above performance parameters, the thickness of the first cover plate 11 may be 0.9-1.1mm, such as 0.9mm, 1mm, 1.1 mm. The first cover plate with the thickness can meet the requirements of stress, strength, weight, wear resistance and the like. And the inventor discovers that the thickness of glass in the laser hole of the existing shell is usually 2mm, and the first cover plate in the laser hole is formed by acrylic plastic in the laser hole, so that the thickness of the first cover plate can be effectively reduced, and the use accuracy of the laser sensor is improved.
In some examples of the present application, referring to fig. 2, the housing body 100 may further have a second through hole 20 (as shown in fig. 3) for carrying a flash lamp, the second through hole 20 has a second cover plate 21, the light transmittance of the second cover plate 21 is not less than 85%, and the heat-resistant temperature is greater than 150 ℃. Therefore, the second cover plate has high light transmittance and good high-temperature resistance, and meets the application conditions of the flash lamp.
Since the second through hole for carrying the flash lamp and the second cover plate are not in interference fit, the material forming the second cover plate may not be particularly limited as long as the conditions that the light transmittance is not less than 85% and the heat-resistant temperature is greater than 150 ℃ are satisfied, and those skilled in the art may design the second cover plate according to specific situations.

From this, the third apron has higher luminousness, satisfies the application condition of the module of making a video recording.
Because the third through hole for bearing the camera module and the third cover plate are not in interference fit, the material for forming the third cover plate is not particularly limited as long as the condition that the light transmittance is not less than 92% is met, and the third cover plate can be designed by a person skilled in the art according to specific situations. For example, the material forming the third cover plate 31 may be glass.

Through the through-hole to being used for bearing the flash light to and be used for bearing the position of the through-hole of the module of making a video recording and improve, on the one hand, under the mode of taking a picture of flash light, can guarantee the light effect when the camera is taken a picture, central luminance and degree of consistency requirement promptly, for prior art, the degree of consistency of this application can improve 15%, and on the other hand can also prevent the light leak, further improves the shooting effect.
In some examples of the application, a camera can be arranged at the third through hole, the central axis of the flash lamp and the camera are on the same straight line, and meanwhile, the distance between the centers of the flash lamp and the camera is 8-15mm, so that a good shooting effect can be achieved when the camera is used for shooting.
Or, in other examples of the present application, the third through hole 30 may further include a plurality of sub holes, wherein one sub hole is used for carrying the wide-angle camera, the central axis of the second through hole 20 is collinear with the central axis of the sub hole for carrying the wide-angle camera, and the distance between the center of the second through hole 20 and the center of the sub hole for carrying the wide-angle camera is 8-15 mm. From this, can prevent the light leak, can improve the degree of consistency that wide-angle camera shot simultaneously, improve wide-angle camera's shooting effect, because wide-angle camera compares in other cameras and has great shooting angle, have under the circumstances of good degree of consistency when guaranteeing wide-angle camera to shoot, also have good degree of consistency when guaranteeing other cameras to shoot for other cameras obtain good shooting effect.
The number of the sub-holes and the positional relationship of the plurality of sub-holes are not particularly limited as long as the plurality of sub-holes are adjacently disposed and when one of them is presentWhen the sub-hole is used for bearing the wide-angle camera, as long as the central axis of the second through hole is on the same straight line with the central axis of the sub-hole used for bearing the wide-angle camera, and the distance between the centers of the second through hole and the sub-hole meets 8-15mm, the person skilled in the art can design according to specific situations. For example, in the specific example of the present application, referring to fig. 3, the third through hole 30 may include 4 sub-holes, such as sub-hole 32 may be used for carrying the main camera, sub-hole 33 may be used for carrying the wide-angle camera, sub-hole 34 may be used for carrying the zoom camera, sub-hole 35 may be used for carrying the macro camera, and the central axes of the 4 sub-holes are on the same straight line L1The central axis of the second through hole 20 and the central axis of the sub-hole 33 are on the same straight line L2Upper, straight line L1And a straight line L2The included angle between the two holes can be 90 degrees, and the distance between the second through hole 20 and the center of the sub-hole 33 is 8-15 mm. Therefore, each camera can have a good shooting effect, and the appearance of the shell has good aesthetic feeling.
In other specific examples of the present application, for example, the plurality of sub-holes of the third through hole 30 have a sub-hole for carrying the main camera, and have no sub-hole for carrying the wide-angle camera, in this case, the central axis of the second through hole 20 may be collinear with the central axis of the sub-hole for carrying the main camera, and the distance between the second through hole 20 and the center of the sub-hole for carrying the main camera is 8-15 mm. Therefore, each camera can have a good shooting effect.
In some examples of the present application, referring to fig. 3, the central axis of the first through-hole 10 and the central axis of the second through-hole 20 are on the same straight line L3And the distance between the center of the first through hole 10 and the center of the second through hole 20 may be 4-6mm, such as 4mm, 5mm, 6 mm. The inventors have found that when the distance between the centers of the first through hole and the second through hole is smaller than the above range, interference between the flash lamp and the laser sensor may occur, which may affect the use of the device, and when the distance between the centers of the first through hole and the second through hole is larger than the above range, which may result in the flash lamp and the laser sensor being farther apart, the distance between the laser sensor and the target being measured, and the distance between the flash lamp and the target being measuredThe distance difference between the two is large, and the distance between the flash lamp and the target object cannot be reflected by the distance measured by the laser sensor, so that the current of the flash lamp cannot be effectively adjusted by the laser sensor, and the shooting effect of the flash lamp cannot be effectively improved.
