[0048] In order to make the purpose, technical solution and advantages of this application more clear, the following is a further detailed description of this application in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain this application and do not limit the scope of protection of this application.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0050] Vehicles such as sedans, SUVs, multi-purpose vehicles, off-road vehicles, buses, and RVs bring a lot of convenience to people's lives, work, and studies, and they play an important role in people's travel. However, there are many types and brands of vehicles, which makes it possible for people to choose from many vehicles. How to reduce maintenance costs, improve product competitiveness, and win people's favor has become an issue that vehicle manufacturers are paying more and more attention to.

[0051] In order to obtain driving information of the vehicle during driving, more and more vehicles will integrate camera devices to obtain vehicle exterior images and / or vehicle interior images.

[0052] In the related art, during the assembly process of the camera device, active alignment is required, so that the lens assembly and the protective shell assembly are determined in relative position, and then fixed by glue, so that the lens assembly is bonded and fixed to the shell. However, the structural defects of the traditional protective shell assembly or lens assembly cause the adhesive to fail easily, which is not conducive to improving the durability of the camera device and reducing the maintenance cost of the vehicle.

[0053] Based on this, the utility model provides a shell, which is applied to a protective shell assembly or a lens assembly, and can improve the bonding strength between the protective shell assembly and the lens assembly, thereby improving the durability of the camera device and reducing the maintenance cost of the vehicle.

[0054] In order to better understand the housing 110 of the present invention, an explanation is given by taking the camera device 100 to which the housing 110 is applied.

[0055] like Figures 1 to 3 As shown, in some embodiments of the present application, a camera device 100 is provided, including a housing 110, a protective shell assembly 120, a lens assembly 130 and an image sensor assembly 140. The protective shell assembly 120 is provided with a protective cavity 121, and the image sensor assembly 140 is arranged in the protective cavity 121. The lens assembly 130 includes a mounting shell 131 fixed to the protective shell assembly 120 and a lens body 132 installed in the mounting shell 131, and a light path is formed between the lens body 132 and the image sensor assembly 140. In this way, it is convenient to use the protective cavity 121 to protect the image sensor assembly 140, thereby improving the anti-interference ability of the camera device 100. At the same time, external light can be better refracted into the image sensor assembly 140 through the lens, thereby improving the image quality of the camera device 100.

[0056] like Figures 2 to 5 As shown, the shell 110 includes a shell body 111, and the shell body 111 includes a light-transmitting area 101, an annular adhesive surface 102, a first retaining ring 103, and a second retaining ring 104. The annular adhesive surface 102, the first retaining ring 103, and the second retaining ring 104 are respectively arranged around the light-transmitting area 101. The first retaining ring 103 and the second retaining ring 104 are fixedly arranged on the annular adhesive surface 102 to form an annular adhesive groove 105. The shell body 111 also includes at least one matching portion 1021 arranged on the annular adhesive surface 102, and the matching portion 1021 is arranged in the adhesive groove 105, and there is a height difference with the annular adhesive surface 102.

[0057] Among them, combined Figure 2 as well as Fig.10As shown, the shell body 111 is fixed to at least one of the protective shell assembly 120 and the mounting shell 131 , and at least a portion of the adhesive 150 is disposed in the adhesive groove 105 so that the mounting shell 131 is bonded and fixed to the protective shell assembly 120 .

[0058] In this way, during the assembly of the camera device 100, the protective shell assembly 120 and / or the mounting shell 131 are fixed with the shell body 111. It is convenient to use the annular adhesive surface 102, the first retaining ring 103 and the second retaining ring 104 to form a glue containing groove 105 to better accommodate the adhesive 150, reduce or avoid the adhesive 150 overflowing and affecting the bonding strength. At the same time, at least one matching portion 1021 is provided in the adhesive containing groove 105, and there is a height difference with the annular adhesive surface 102, which can increase the area, so as to further increase the contact area between the shell body 111 and the adhesive 150, improve the bonding strength, and make the protective shell assembly 120 and the lens assembly 130 firmly bonded, thereby improving the durability of the camera device 100.

[0059] In addition, there is a height difference between the matching portion 1021 and the annular adhesive surface 102, so that even if the liquid enters the adhesive groove 105, it will flow to the low-lying part of the adhesive groove 105. This changes the liquid flow path, facilitates the use of the low-lying part of the adhesive groove 105 to store liquid, avoids or reduces the liquid from entering the light-transmitting area 101, and improves the waterproof effect of the camera device 100.

[0060] When the camera device 100 is in use, external light is refracted by the lens body 132 and incident on the image sensor component 140 through the light-transmitting area 101 . The image sensor component 140 is used to collect optical information to obtain an image.

[0061] It can be understood that there is a height difference between the matching portion 1021 and the annular adhesive receiving surface 102 , and thus there is a low-lying area in the adhesive containing groove 105 .

[0062] It should be noted that there may be many specific implementations of the “image sensing component 140 ”, including at least an image sensor 141 .

[0063] Combination Figure 3 As shown, the shell body 111 is fixed on the protective shell assembly 120. During the assembly of the camera device, active alignment is required to determine the relative position of the lens assembly 130 and the protective shell assembly 120, and the shell body 111 and the mounting shell 131 are spaced apart along the Z-axis direction, and then the adhesive 150 is filled between the shell body 111 and the mounting shell 131 to fix the shell body 111 and the mounting shell 131, and the lens assembly 130 is bonded and fixed to the protective shell assembly 120.

[0064] See you later Figure 2As shown, optionally, the image sensing assembly 140 includes a circuit board 142 and an image sensor 141 disposed on the circuit board 142 , and the image sensor 141 can receive light incident from the lens assembly 130 .

[0065] Reference Figure 2 as well as Figure 4 As shown, in some embodiments, the matching portion 1021 is convex. The annular adhesive bearing surface 102 is provided with a plurality of matching portions 1021, and is arranged at intervals along the circumference of the adhesive groove 105. In this way, the matching portion 1021 is convex, which can make full use of the depth space of the adhesive groove 105 to increase the area, increase the contact area between the shell body and the adhesive, and thus improve the bonding strength. The plurality of matching portions 1021 are arranged at intervals along the circumference of the adhesive groove 105, further increasing the contact area between the shell body and the adhesive, and also making multiple depressions exist in the circumference of the adhesive groove 105, thereby improving the waterproof effect of the camera device in the circumference of the light-transmitting area 101.

[0066] Reference Figure 2 , Figure 4 as well as Fig. 9 As shown, further, in some embodiments, two adjacent matching parts 1021 are spaced apart, and a concave surface 1022 is formed on the annular adhesive bearing surface. Along the circumferential direction of the adhesive containing groove 105, the width of the concave surface 1022 is less than or equal to the width of the matching part 1021. In this way, the contact area between the shell body 111 and the adhesive 150 is further increased by using the concave-convex matching. In addition, it is convenient to use the concave surface 1022 to form a low-lying area of ​​the adhesive containing groove, so that even if the liquid enters the adhesive containing groove, it will flow to the concave surface 1022. In addition, the liquid flow path is changed, and the concave surface 1022 is used to store liquid, thereby avoiding or reducing the liquid from entering the light-transmitting area 101, thereby improving the waterproof effect of the camera device 100.

[0067] It is understandable that the concave surface 1022 can also be used as a concave portion. In this way, it is convenient to form a concave-convex matching structure on the shell body 111 to further increase the contact area between the shell body 111 and the adhesive 150 .

[0068] Optionally, in some embodiments, relative to the annular adhesive bearing surface 102, the protruding height of at least one matching portion 1021 is less than or equal to the protruding height of other matching portions 1021. In this way, the height of the matching portion 1021 can be flexibly set according to product requirements to take into account the strength requirements of the housing 110 and the bonding strength requirements.

[0069] like Figures 6 to 8As shown, in some embodiments, the matching portion 1021 is convex. Relative to the annular adhesive surface 102, the protruding height of the matching portion 1021 is less than or equal to the blocking height of the first retaining ring 103 and the blocking height of the second retaining ring 104. In this way, when the adhesive 150 fills the adhesive groove 105, an annular adhesive layer can be formed after curing, which has good sealing performance, thereby improving the sealing performance of the camera device 100.

[0070] Specifically, combined Figure 8 As shown, in the Z-axis direction, that is, the depth direction of the adhesive groove 105, the protruding height of the matching portion 1021 is H1, the blocking height of the first retaining ring 103 is H2, and the blocking height of the second retaining ring 104 is H3. Among them, H1<H2=H3.

[0071] like Figures 6 to 8 As shown, optionally, in some embodiments, relative to the annular adhesive bearing surface 102, the blocking height of the first retaining ring 103 is equal to the blocking height of the second retaining ring 104. In this way, the design is simple and easy to manufacture.

[0072] In other embodiments, the second retaining ring 104 is disposed farther from the light-transmitting area 101 than the first retaining ring 103, and the blocking height of the second retaining ring 104 relative to the annular adhesive-bearing surface 102 is higher than the blocking height of the first retaining ring 103. In this way, the adhesive 150 is facilitated to gather toward the first retaining ring 103, and the second retaining ring 104 is used to prevent the adhesive from overflowing.

[0073] like Figure 2 as well as Figure 3 As shown, in some embodiments, the protective shell assembly 120 includes a protective front shell 122 and a protective rear shell 123 that cooperates with the protective front shell 122 to form a protective cavity 121, the image sensor assembly 140 is fixed to the protective front shell 122, and the shell body 111 is fixed to the protective front shell 122. In this way, when the camera device 100 is assembled, the lens body 132 is first assembled to the mounting shell 131 to complete the assembly of the lens assembly 130. Then the image sensor assembly 140 is fixed to the protective front shell 122. After the assembly of the lens assembly 130 and the protective front shell 122 is completed, and during the assembly of the two, the relative position between the lens body 132 and the image sensor assembly 140 is determined by active alignment, and then the adhesive 150 is filled between the mounting shell 131 and the protective front shell 122, and the two are fixed together by the adhesive 150. Finally, the protective front shell 122 and the lens assembly 130 after the glue is cured are fixed together with the protective rear shell 123 to protect the image sensor assembly 140 in the protective cavity 121, thereby completing the assembly of the camera device 100.

[0074] Since the protective front shell 122 is fixedly provided with the shell body 111 , the protective front shell 122 and the lens assembly 130 are firmly bonded, thereby improving the durability of the camera device 100 .

[0075] like Figure 4 As shown, in some embodiments, the shell body 111 and the protective front shell 122 are integrally formed. In this way, it is convenient to use injection molding and other processes to integrally manufacture the shell body 111 and the protective front shell 122, which is conducive to reducing assembly processes and improving assembly efficiency.

[0076] It should be noted that the "shell 110" can be a "part of the protective front shell 122", that is, the "shell 110" and the "other parts of the protective front shell 122" are manufactured as one piece; it can also be an independent component separable from the "other parts of the protective front shell 122", that is, the "shell 110" can be manufactured independently and then combined with the "other parts of the protective front shell 122" into a whole.

[0077] Equivalently, "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; or it can be an independent component separable from the "other parts of the component", that is, "some body" or "some part" can be independently manufactured and then combined with the "other parts of the component" into a whole. The expression of the above-mentioned "some body" or "some part" in this application is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this application. As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of this application.

[0078] Optionally, in some embodiments, the material of the protective front shell 122 is an infrared-transmitting material, and the material of the protective rear shell 123 is a light-absorbing material.

[0079] It should be noted that “the shell body 111 is fixedly mounted on at least one of the protective shell assembly 120 and the mounting shell 131” includes the shell body 111 being fixedly mounted on the protective shell assembly 120 ( Figure 2 as well as Figure 4 As shown), or the shell body 111 is fixedly mounted on the mounting shell 131 (as shown Fig.10 As shown), or one shell body 111 is fixedly disposed on the protective shell assembly 120, and the other shell body 111 is fixedly disposed on the mounting shell 131.

[0080] Reference Fig.10 As shown, in other embodiments, the housing 110 is a mounting shell 131, and the shell body 111 is fixedly connected to the mounting shell 131. In this way, the shell body 111 can be integrated into the mounting shell 131, and the connection strength between the mounting shell 131 and the protective shell assembly 120 is improved by increasing the contact area between the mounting shell 131 and the adhesive 150.

[0081] Furthermore, in some embodiments, the shell body 111 and the mounting shell 131 are integrally formed. In this way, the shell body 111 and the mounting shell 131 can be integrally manufactured by injection molding or other processes, which is beneficial to reducing assembly processes and improving assembly efficiency.

[0082] Optionally, in some embodiments, the mounting shell 131 includes a flange, and the shell body 111 and the flange are integrally formed. In this way, it is easy to assemble the lens assembly 130 on the protective shell assembly 120.

[0083] like Fig.11 As shown, in some embodiments, the matching portion 1021 is an annular convex body and is arranged around the light-transmitting area 101. In this way, the matching portion 1021 is an annular convex body, which can increase the contact area between the shell body 111 and the adhesive 150, and is convenient for forming a circuitous waterproof structure, which is beneficial to further improve the waterproof performance of the camera device 100.

[0084] Optionally, a half cross-section of the matching portion 1021 is partially circular or partially elliptical.

[0085] like Fig.11 As shown, in one example, the mating portion 1021 is an annular convex body, and the half-section of the mating portion 1021 is semicircular. In this way, the depth space of the adhesive groove 105 (that is, the Z-axis direction) can be fully utilized to increase the area and increase the contact area between the shell body and the adhesive. The multiple annular convex body-shaped mating portions 1021 are arranged at intervals along the width of the adhesive groove 105 (that is, the X-axis direction), which further increases the contact area between the shell body and the adhesive, and also makes the adhesive groove 105 have multiple low-lying areas in the width direction, thereby improving the waterproof effect of the camera device in the circumferential direction of the light-transmitting area 101.

[0086] like Fig.12 As shown, in other embodiments, the matching portion 1021 is in the shape of a concave hole, and multiple matching portions 1021 are arranged at intervals along the circumference of the adhesive groove 105. In this way, the matching portion 1021 is in the shape of a concave hole, which can fully utilize the depth space of the adhesive groove 105 to increase the area, increase the contact area between the shell body and the adhesive, and thus improve the bonding strength. Multiple matching portions 1021 are arranged at intervals along the circumference of the adhesive groove 105, further increasing the contact area between the shell body and the adhesive.

[0087] In addition, the matching portion 1021 is in the shape of a concave hole, which is convenient for forming a low-lying area in the glue containing groove 105, so that even if the liquid enters the glue containing groove 105, it will flow to the low-lying area of ​​the glue containing groove 105. In addition, the liquid flow path is changed, and the low-lying area of ​​the glue containing groove 105 is convenient for storing liquid, thereby avoiding or reducing the liquid from entering the light-transmitting area 101, and improving the waterproof effect of the camera device 100.

[0088] In other embodiments, the matching portion 1021 is in the shape of an annular groove and is disposed around the light-transmitting area 101. In this way, the matching portion 1021 is in the shape of an annular groove, which can increase the contact area between the shell body 111 and the adhesive 150, thereby improving the bonding strength, and is convenient for forming a circuitous waterproof structure, which is beneficial to further improve the waterproof performance of the camera device 100.

[0089] It should be noted that the "protective front shell 122" can be one of the parts of the module "protective shell assembly 120", that is, it can be assembled into a module with the "other components of the protective shell assembly 120", and then modularly assembled; it can also be relatively independent of the "other components of the protective shell assembly 120", and can be installed separately, that is, it can form a whole with the "other components of the protective shell assembly 120" in this device.

[0090] Equivalently, the components included in the "assembly", "component", "device" and "equipment" of this application can also be flexibly combined, that is, modular production can be carried out according to actual conditions, modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in this device.
