Description

Technical Field

[0001] This application relates to the field of camera technology, and in particular to a camera structure, housing, and rivet assembly. Background Technology

[0002] The camera structure may include a housing and a substrate. The housing has rivets, and the substrate has rivet holes. The substrate is fixed to the housing by the rivets engaging with the rivet holes.

[0003] In existing technologies, during the riveting process, the riveted parts in the riveting holes undergo upsetting under the influence of riveting pressure. During the upsetting process, due to the inconsistent riveting pressure on the riveting holes, the substrate is prone to lifting on one side, causing the substrate to warp. As a result, the assembly accuracy of the shell and the substrate during the riveting process is poor, affecting the yield of the finished product. Utility Model Content

[0004] This application provides a camera structure, housing, and rivet assembly to address the problem of improving the assembly accuracy of the housing and substrate during the riveting process and increasing the yield of finished products.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a camera structure, which includes a housing and a substrate. The housing includes a housing body and at least one rivet disposed on the inner surface of the housing body, the inner surface of the housing body having at least one rivet being a first inner surface. The substrate is housed within the housing body, and the substrate has at least one rivet hole, the diameter of which increases from one end toward the first inner surface to one end away from the first inner surface, and at least one rivet fastener is fitted and housed in the at least one rivet hole.

[0007] In this way, during the riveting process, the riveting component can apply a force towards the first inner surface to the wall of the riveting hole, so that the substrate is in contact with the first inner surface, avoiding the substrate from lifting relative to the first inner surface and causing it to warp. This helps to ensure the assembly accuracy of the shell and the substrate during the riveting process and improves the yield of the finished camera structure.

[0008] In some embodiments, the riveting hole includes a tapered section, the smaller end of the tapered section facing the first inner surface, and the larger end of the tapered section located on the surface of the substrate opposite to the first inner surface.

[0009] In some embodiments, the riveting hole further includes a straight cylindrical section located between the tapered cylindrical section and the first inner surface, and the smaller end of the opening of the tapered cylindrical section is connected to the straight cylindrical section.

[0010] In some embodiments, the size of the tapered section is larger than the size of the straight section along the axial direction of the riveting hole.

[0011] In some embodiments, the end face of the rivet opposite to the first inner surface is flush with the surface of the substrate opposite to the first inner surface.

[0012] In some embodiments, the number of riveting components is multiple, including a first riveting component and a second riveting component; the number of riveting component holes is multiple, including a first riveting hole and a second riveting hole, the first riveting component is fitted into the first riveting hole, and the second riveting component is fitted into the second riveting hole.

[0013] In some embodiments, the first riveting hole is a circular riveting hole, and the second riveting hole is an elliptical riveting hole.

[0014] In some embodiments, the camera structure further includes an image sensor disposed on a substrate.

[0015] In a second aspect, a housing is provided for accommodating a substrate, the substrate having a circular riveting hole and an elliptical riveting hole, the housing including a housing body and a first rivet and a second rivet disposed on the inner surface of the housing body, the first rivet being adapted to be riveted in the circular riveting hole to form a first riveted member, the second rivet being adapted to be riveted in the elliptical riveting hole to form a second riveted member, the height of the second rivet being greater than the height of the first rivet.

[0016] The volume of an elliptical rivet hole is usually larger than that of a circular rivet hole because the height of the second rivet is greater than that of the first rivet. Thus, during the riveting process, the difference in filling height between the second rivet in the elliptical rivet hole and the first rivet in the circular rivet hole is smaller, resulting in a more balanced riveting force and preventing the substrate from warping on one side.

[0017] Optionally, provided that the diameters of the second rivet and the first rivet are the same, the height difference between the height of the second rivet and the height of the first rivet is greater than or equal to 0.5 times the thickness of the substrate and less than or equal to 0.7 times the thickness of the substrate.

[0018] Thirdly, a rivet assembly is provided, suitable for riveting a housing and a substrate. The housing includes a housing body and a first rivet and a second rivet disposed on the inner surface of the housing body. The substrate is provided with a circular riveting hole and an elliptical riveting hole. The rivet assembly includes a first rivet and a second rivet. The first rivet is adapted to rivet a first rivet in the circular riveting hole, and the second rivet is adapted to rivet a second rivet in the elliptical riveting hole. The height of the second rivet is greater than the height of the first rivet.

[0019] During the riveting and upsetting process, the first rivet can be riveted into a circular riveting hole using a first rivet, and the second rivet can be riveted into an elliptical riveting hole using a second rivet. By making the height of the second rivet greater than that of the first rivet, the compressive force applied by the second rivet to the second rivet is greater than that applied by the first rivet to the first rivet. This allows the upsetting speed of the second rivet to be greater than that of the first rivet, enabling the first and second rivets to complete the riveting process approximately synchronously, avoiding asynchrony and resulting in one-sided lifting. This improves the assembly accuracy of the shell and the substrate, increasing the yield rate of the finished product. Attached Figure Description

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0042] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0043] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the camera structure 100 provided in some embodiments of this application from one viewpoint. Figure 2 for Figure 1 The diagram shows the structure of the camera structure 100 from another perspective. The camera structure 100 can be used to capture images. In some embodiments, the camera structure 100 can be used as a camera on a vehicle. In other embodiments, the camera structure 100 can also be used as a camera on a monitor or a camera on a mobile phone, etc. This application does not specifically limit the application scenarios of the camera structure 100.

[0044] Please see Figure 3 , Figure 3 for Figure 1 The image shows a top view of the camera structure 100. The camera structure 100 may include a housing 1 and a substrate 2. The housing 1 may be provided with a riveting member 13, and the substrate 2 may be provided with a riveting hole 2A. Exemplarily, the housing 1 may be a front housing, but it can also be a rear housing, etc. This application does not specifically limit the structural shape of the housing 1. The substrate 2 may be a circuit board, and the substrate 2 may support an image sensor to facilitate electrical connection between the image sensor and other electronic components. The riveting member 13 is fitted into the riveting hole 2A to achieve the assembly of the housing 1 and the substrate 2.

[0045] Based on this, the substrate 2 is assembled to the housing 1 using a riveting process. During the riveting process, due to the influence of riveting pressure, the riveting component 13 in the riveting hole 2A undergoes upsetting. During the upsetting process, because the riveting pressure on the riveting hole 2A is inconsistent, it is easy for one side of the substrate 2 to be lifted relative to the housing 1, causing a warping phenomenon, which affects the assembly accuracy of the housing 1 and the substrate 2, and is not conducive to ensuring the yield of the finished product of the camera structure 100. Here, upsetting can be understood as the riveting component 13 changing from a slender shape to a thicker shape while maintaining its volume during the riveting process.

[0046] Specifically, the deformation of the riveted part 13 and the stress analysis of the riveting hole 2A during the riveting and upsetting process are as follows:

[0047] During the riveting upsetting process of the riveting part 13, the cylindrical shape of the riveting part 13 will be distorted. According to the study of cylindrical upsetting, the following has been found:

[0048] When d / h>1 / 2, the riveted part 13 may exhibit a single drum shape, with the deformation initially occurring in the middle of the riveted part 13.

[0049] When d / h < 1 / 2, the riveting part 13 first appears dumbbell-shaped (both ends of the riveting part 13), and as the upsetting proceeds, it gradually changes from dumbbell shape to single drum shape.

[0050] Where d is the diameter of the riveted part 13 before riveting upsetting; h is the height of the riveted part 13 before riveting upsetting.

[0051] Please see Figure 4 and Figure 5 , Figure 4 for Figure 1 The diagram shows the deformation of the rivet 13 in the camera structure 100. Figure 5 for Figure 4 The diagram shows the structural structure of the riveting hole 2A corresponding to the riveting component 13 under stress. In practical applications, the ratio of d / h will reach 1:5, therefore, during the riveting process, the riveting component 13 will first exhibit dumbbell deformation. Upsetting will also occur at the bottom of the riveting component 13, compressing the substrate 2.

[0052] Because the deformation of the riveting component 13 is constrained at different levels around its perimeter, the deformation of the riveting component 13 is limited by the shell and the wall of the riveting hole 2A. After filling the bottom, the riveting component 13 continues to fill upwards along the hole wall. That is, the force exerted by the riveting component 13 on different positions of the hole wall varies, and the force exerted by the riveting component 13 on the hole wall of the riveting hole 2A gradually decreases along the thickness direction of the outer shell 1. Specifically, the force exerted on the riveting component 13 at the root of the substrate 2 results in greater deformation, while the force exerted further away from the root results in smaller deformation. When there is a gap between the substrate 2 and the outer shell 1, the substrate 2 is prone to lifting.

[0053] Please see Figures 6 to 9 , Figure 6 for Figure 4 A structural schematic diagram of the deformation process of the riveted component 13 shown. Figure 7 for Figure 6 The diagram shows the structural deformation process of the riveted component 13. Figure 8 for Figure 7 The diagram shows the structural deformation process of the riveted component 13. Figure 9 for Figure 4 Another structural schematic diagram of the deformation process of the riveting component 13 is shown. During upsetting, the deformation of the riveting component 13 starts from the bottom and moves upwards, posing a risk of upward displacement of the base plate 2. Furthermore, since the ratio of the diameter to the height of the riveting component 13 is 1:5 during riveting, the bottom of the riveting component 13 begins to deform during the riveting process, as shown... Figures 6 to 8 As shown. The riveting member 13 fills the riveting hole 2A starting from the root of the substrate 2. During the filling process, the force exerted by the riveting member 13 on the hole wall of the riveting hole 2A is F1. F1 causes the substrate 2 to shift under force, such as upwards or in the radial direction of the riveting hole 2A. Figure 9 As shown.

[0054] To resolve the above issues, please refer to Figure 3 , Figure 10 and Figure 11 , Figure 10 for Figure 3 The diagram shows a cross-sectional view of the camera structure 100 along line AA. Figure 11 for Figure 3 The diagram shows a cross-sectional view of the camera structure 100 along line BB. The housing 1 may include a housing body 11 and at least one rivet 13 disposed on the inner surface of the housing body 11. The inner surface of the housing body 11 with at least one rivet 13 is a first inner surface 12. A substrate 2 is housed within the housing body 11, and the substrate 2 has at least one rivet hole 2A. The diameter of the rivet hole 2A increases from one end facing the first inner surface 12 to the end away from the first inner surface 12, and at least one rivet 13 is fitted and accommodated within at least one rivet hole 2A.

[0055] In this way, during the riveting and upsetting process, the riveting component 13 can apply a force to the wall of the riveting hole 2A pointing towards the first inner surface 12, so that the substrate 2 is in contact with the first inner surface 12, avoiding the substrate 2 from being lifted relative to the first inner surface 12 and causing it to warp. This helps to ensure the assembly accuracy of the housing 1 and the substrate 2 during the riveting process and improves the yield of the camera structure 100.

[0056] In some examples, there can be multiple riveting parts 13 and multiple riveting holes 2A. The number of multiple riveting parts 13 and multiple riveting holes 2A is equal and corresponds one-to-one, that is, one riveting part 13 can be fitted into one riveting hole 2A. In this way, by using multiple riveting parts 13 and multiple riveting holes 2A, the assembly of the outer shell 1 and the base plate 2 can be achieved, thereby improving assembly efficiency.

[0057] For example, the number of rivet 13 and rivet hole 2A can both be two. In addition, the number of rivet 13 and rivet hole 2A can also be other numbers, such as three, four, five, etc., and this application does not specifically limit them.

[0058] In some embodiments, the riveting hole 2A may include a tapered section 21, with the smaller end of the tapered section 21 facing the first inner surface 12 and the larger end of the tapered section 21 located on the surface of the substrate 2 opposite to the first inner surface 12.

[0059] In this way, during the riveting process, the riveting component 13 can easily apply a force towards the first inner surface 12 to the hole wall of the tapered section 21, so that the substrate 2 and the first inner surface 12 are evenly and continuously attached, improving the stability and continuity of the riveting component 13 under force, and preventing the substrate 2 from lifting relative to the first inner surface 12 and causing warping. This can improve the assembly accuracy of the shell 1 and the substrate 2 during the riveting process and increase the yield of finished products. In addition, the structure of this riveting hole 2A is simple and easy to form.

[0060] Of course, in some other embodiments, the riveting hole 2A may include two straight cylindrical sections 22 with different diameters, which can also prevent the substrate 2 from being lifted. The embodiments described below are further descriptions based on the riveting hole 2A including the tapered cylindrical section 21, and should not be considered as a special limitation on the structural form of the riveting hole 2A.

[0061] In some examples, the tapered section 21 extends through the entire substrate 2. In other examples, the tapered section 21 may also extend through a portion of the substrate 2.

[0062] In some embodiments, the riveting hole 2A may further include a straight cylindrical section 22, which is located between the tapered cylindrical section 21 and the first inner surface 12, and the smaller end of the opening of the tapered cylindrical section 21 is connected to the straight cylindrical section 22.

[0063] In this way, the straight section 22 is easy to process, which makes it easier to ensure the dimensional accuracy of the riveting hole 2A, improves the assembly accuracy of the outer shell 1 and the base plate 2 during the riveting process, and increases the yield of finished products.

[0064] In some examples, a circular arc transition can be used between the smaller end of the conical section 21 and the straight section 22.

[0065] In some other embodiments, the riveting hole 2A may include a tapered section 21 but not a straight section 22. That is, the tapered section 21 extends through the entire substrate 2.

[0066] This application uses the riveting hole 2A, which includes a tapered section 21 and a straight section 22, as an example for illustrative purposes.

[0067] In some embodiments, along the axial direction of the riveting hole 2A, the dimension L1 of the tapered section 21 may be greater than the dimension L2 of the straight section 22.

[0068] This effectively achieves the bonding between the substrate 2 and the outer shell 1, preventing the substrate 2 from lifting relative to the first inner surface 12 and causing it to warp. This ensures the assembly accuracy of the outer shell 1 and the substrate 2 during the riveting process and improves the yield of finished products. At the same time, the straight cylindrical section 22 effectively ensures the dimensional accuracy of the riveting hole 2A.

[0069] In some other embodiments, the size of the tapered section 21 along the axial direction of the riveting hole 2A may be less than or equal to the size of the straight section 22.

[0070] In some embodiments, the end face of the rivet 13 facing away from the first inner surface 12 is flush with the surface of the substrate 2 facing away from the first inner surface 12.

[0071] In this way, after the substrate 2 is riveted, the end face of the riveting part 13 is flush with the surface of the substrate 2, which can enhance the flatness requirements of the assembly surface of the housing 1 and the substrate 2 and avoid interference between the riveting part 13 and other electronic components on the substrate 2.

[0072] In some other embodiments, the end face of the rivet 13 is not flush with the surface of the substrate 2; for example, the end face of the rivet 13 is lower or higher than the surface of the substrate 2.

[0073] In some embodiments, please refer to Figure 3 , Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the structure before the riveting component 13 is riveted to the riveting hole 2A. Figure 13 This is a schematic diagram of the structure after the riveting member 13 is riveted to the riveting hole 2A. There are multiple riveting members 13, including a first riveting member 131 and a second riveting member 132. There are also multiple riveting holes 2A, including a first riveting hole 23 and a second riveting hole 24. The first riveting member 131 is fitted into the first riveting hole 23, and the second riveting member 132 is fitted into the second riveting hole 24.

[0074] Therefore, during the riveting process, please refer to... Figure 14 and Figure 15 , Figure 14This is a schematic diagram showing the force relationship between the first riveting member 131 and the first riveting hole 23. Figure 15 This is a schematic diagram showing the force relationship between the second riveting member 132 and the second riveting hole 24. The first riveting member 131 can apply a force pointing towards the first inner surface 12 to the hole wall of the first riveting hole 23, and the second riveting member 132 can apply a force pointing towards the first inner surface 12 to the hole wall of the second riveting hole 24, so as to ensure that the substrate 2 is in contact with the first inner surface 12 and avoid the substrate 2 from lifting relative to the first inner surface 12 and causing it to warp, thereby improving the assembly accuracy of the shell 1 and the substrate 2 and improving the yield of finished products.

[0075] In some other embodiments, the number of both the riveting member 13 and the riveting hole 2A may be one.

[0076] In some embodiments, the first riveting hole 23 can be a circular riveting hole 231, and the second riveting hole 24 can be an elliptical riveting hole 241.

[0077] In this way, during the riveting process, the circular riveting hole 231 can position the first riveting part 131, and the elliptical riveting hole 241 can compensate for the dimensional tolerance of the second riveting part 132, so as to ensure that the substrate 2 and the first inner surface 12 of the shell 1 are in contact, and avoid the substrate 2 from being lifted relative to the first inner surface 12 and causing it to warp, thereby improving the assembly accuracy of the shell 1 and the substrate 2 and increasing the yield of finished products.

[0078] In some other embodiments, the first riveting hole 23 and the second riveting hole 24 may have the same structure. For example, the first riveting hole 23 and the second riveting hole 24 may both be circular riveting holes 231 or elliptical riveting holes 241.

[0079] In some embodiments, the camera structure 100 further includes a lens attached to the housing 1.

[0080] In this way, the lens can capture the light of the subject (such as scenery, people, etc.) and focus the captured light onto the image sensor to form an image corresponding to the subject.

[0081] In some examples, the lens includes a lens element, which can be a plastic lens, a glass lens, etc.

[0082] In some examples, the connection between the lens and the housing 1 can be a threaded connection, snap-fit, welding, etc., and this application does not make specific limitations on this.

[0083] In some embodiments, the camera structure 100 may further include an image sensor disposed on the substrate 2.

[0084] In this way, the image sensor can convert the light captured by the lens into electrical signals, which can then be processed and stored by the image signal processor.

[0085] In some examples, the image sensor can be a CCD (Complementary Metal-Oxide Semiconductor) image sensor, a CMOS (Charge-Coupled Device) image sensor, and so on.

[0086] After the substrate 2 is riveted, the image sensor on the substrate 2 is parallel to the plane of the lens, that is, the CRA (Chief Ray Angle) of the image sensor and the lens are matched to improve image quality. Here, CRA refers to the maximum angle of light that can be focused onto a pixel from the lens sensor side.

[0087] This application also provides a housing 1, which can be the housing 1 of the camera structure 100 described in any of the above embodiments. The housing 1 is used to accommodate a substrate 2, the substrate 2 is provided with a circular riveting hole 231 and an elliptical riveting hole 241, and the housing 1 includes a housing body 11 and a first rivet 133 and a second rivet 134 disposed on the inner surface of the housing body 11. The first rivet 133 is adapted to be riveted into the circular riveting hole 231 to form the first riveting member 131, and the shape of the first riveting member 131 is adapted to the shape of the circular riveting hole 231. The second rivet 134 is adapted to be riveted into the elliptical riveting hole 241 to form the second riveting member 132, and the shape of the second riveting member 132 is adapted to the shape of the elliptical riveting hole 241. The height of the second rivet 134 is greater than the height of the first rivet 133.

[0088] In this way, during the riveting process, the first rivet 133 is upset to fit into the circular riveting hole 231, and the second rivet 134 is upset to fit into the elliptical riveting hole 241.

[0089] When riveting with circular riveting holes 231 and elliptical riveting holes 241, the space around the elliptical riveting hole 241 is larger, and the deformation expansion area during upsetting is larger than that of the circular riveting hole 231. Furthermore, if the height of the second rivet 134 is the same as the height of the first rivet 133, the height difference between the first riveting member 131 and the second riveting member 132 formed after upsetting is significant. This results in different forces exerted on the substrate 2 by the first riveting member 131 and the second riveting member 132, specifically causing greater pressure at the circular riveting hole 231 than at the elliptical riveting hole 241. Because the pressure on both ends of the substrate 2 is different, insufficient pressing of the substrate 2 at the elliptical riveting hole 241 can easily occur, causing the substrate 2 at the elliptical riveting hole 241 to lift and warp.

[0090] Based on this, by making the height of the second rivet 134 greater than the height of the first rivet 133, the deformation of the second rivet 134 during the riveting process can be compensated, so that the substrate 2 and the first inner surface 12 fit better. The difference between the filling height of the second rivet 134 in the elliptical riveting hole 241 and the filling height of the first rivet 133 in the circular riveting hole 231 is small, and the riveting force is more balanced. This avoids the substrate 2 from being lifted relative to the first inner surface 12 and causing it to warp, thereby improving the assembly accuracy of the outer shell 1 and the substrate 2 and increasing the yield of finished products.

[0091] In some embodiments, the height of the second rivet 134 being greater than the height of the first rivet 133 refers to the height relationship between the second rivet 134 and the first rivet 133, assuming that the diameters of the second rivet 134 and the first rivet 133 are the same.

[0092] In some embodiments, provided that the diameters of the second rivet 134 and the first rivet 133 are the same, the height difference between the heights of the second rivet 134 and the first rivet 133 is greater than or equal to 0.5 times the thickness of the substrate, and less than or equal to 0.7 times the thickness of the substrate. In some embodiments, provided that the diameters of the second rivet 134 and the first rivet 133 are the same, the height difference between the heights of the second rivet 134 and the first rivet 133 is 0.618 times the thickness of the substrate.

[0093] This application also provides a rivet assembly 3, please refer to... Figure 10 , Figure 16 and Figure 17 , Figure 16 This is a structural diagram of the riveting component 13 before it is riveted to the rivet assembly 3. Figure 17 for Figure 16 The diagram shows the structure after the riveting member 13 is riveted to the riveting hole 2A. The rivet assembly 3 is suitable for riveting the outer shell 1 and the substrate 2 of the camera structure described in any of the above embodiments. The outer shell 1 includes an outer shell body 11 and a first rivet 133 and a second rivet 134 disposed on the inner surface of the outer shell body 11. The substrate 2 is provided with a circular riveting hole 231 and an elliptical riveting hole 241. The rivet assembly 3 includes a first rivet 31 and a second rivet 32. The first rivet 31 is suitable for riveting the first rivet 133 into the circular riveting hole 231, and the second rivet 32 ​​is suitable for riveting the second rivet 134 into the elliptical riveting hole 241. The height of the second rivet 32 ​​is greater than the height of the first rivet 31.

[0094] In this way, during the riveting and upsetting process, the first rivet 133 can be riveted into the circular riveting hole 231 using the first rivet 31, and the second rivet 134 can be riveted into the elliptical riveting hole 241 using the second rivet 32. By making the height of the second rivet 32 ​​greater than that of the first rivet 31, the compressive force applied by the second rivet 32 ​​to the second rivet 134 can be greater than the compressive force applied by the first rivet 31 to the first rivet 133. This allows the upsetting speed of the second rivet 134 to be greater than that of the first rivet 31, enabling the first rivet 133 and the second rivet 134 to be riveted approximately synchronously, avoiding asynchrony and resulting in one-sided lifting. This improves the assembly accuracy of the outer shell 1 and the substrate 2, and increases the yield of finished products.
