Description

Technical fields:

[0001] This utility model relates to the field of vehicle camera technology, and specifically refers to a metal camera back cover that can be replaced with various fasteners and colors. Background technology:

[0002] With the rapid development of technology, the technology of intelligent vehicles and in-vehicle cameras is advancing by leaps and bounds. In-vehicle cameras play a crucial role in intelligent vehicles, not only providing drivers with convenient navigation services, but also undertaking the key task of transmitting image signals. They provide strong support for road condition monitoring and safe driving, that is, they can accurately and stably transmit the high-definition video signals captured by the camera to the corresponding receiving devices with extremely low latency, ensuring that the driver can obtain real-time and clear visual information about the vehicle's surroundings, whether it is a reversing image, a 360-degree panoramic image, or a forward road condition monitoring function used to assist driving.

[0003] Existing automotive camera rear housing structures, such as Figure 1-2 As shown, the rear shell structure 1 of the vehicle camera includes a metal shell 101, an outer conductor 102 integrally formed on the upper end of the metal shell 101, an inner conductor 103 that is inserted and fixed inside the outer conductor 102 and designed to be coaxial with the outer conductor 102, an insulator 104 that is inserted in the inner conductor 103 and designed to be coaxial with the inner conductor 103, and a center conductor 105 that is inserted and fixed in the insulator 104 and designed to be coaxial with the insulator 104. The center conductor 105, the inner conductor 103, and the outer conductor 102 are designed to be coaxial, and the inner conductor 103 is insulated from each other by the insulator 103.

[0004] Because the size of the metal shell 11 is larger than that of the outer conductor 12, and the outer conductor 12 has an outwardly protruding latch 121 and rib 122 integrally formed on the outside, the integral structure of the metal shell 11 and the outer conductor 12 results in a complex molding process, especially a complex molding mold structure and high mold opening cost. In addition, the latch 121 on the metal shell 11 has a fixed orientation, meaning that its latch position is fixed and cannot be replaced, making it less flexible in use. Furthermore, the outer conductor 12 cannot be distinguished by color, meaning it is a single color, which lacks interest and foolproof features and cannot meet the user requirements of consumers.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a metal camera back cover that can be interchanged with various fasteners and colors.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The metal camera back cover with interchangeable buckles and colors includes a metal shell and a connector fixed to the metal shell by assembly. The connector includes an outer conductor assembled and fixed to the metal shell, an insulator installed and fixed inside the outer conductor, a central pin set inside the insulator, and a plastic shell with its own color sleeved around the outer conductor. A pair of slots are formed between the plastic shell and the outer conductor, and an outwardly protruding buckle is provided on the outside of the plastic shell.

[0008] Furthermore, in the above technical solution, the upper end of the plastic shell is provided with a stepped groove, and the plastic shell is provided with a through hole that passes through the stepped groove along its lower end. The middle part of the outer conductor is fixed in the through hole, and the upper end of the outer conductor extends into the stepped groove and forms the matching slot with the stepped groove.

[0009] Furthermore, in the above technical solution, the outer conductor has a stop step formed in the middle and a buckle body located above the stop step; the lower part of the through hole is provided with a limiting groove, the upper part of the through hole is provided with a slot, the stop step abuts against the lower end of the limiting groove, and the buckle body extends through the through hole to be snapped and fixed with the slot.

[0010] Furthermore, in the above technical solution, the outer conductor is further provided with several sets of claw buckles on its outer periphery, with two claw buckles in each set, which are symmetrically distributed; the lower part of the through hole is also provided with a limiting protrusion, which is inserted between the two claw buckles.

[0011] Furthermore, in the above technical solution, the metal shell is provided with a mounting hole that passes through its upper and lower end faces. The upper and lower ends of the mounting hole are respectively provided with a first step groove and a riveting groove. The lower end of the outer conductor passes through the mounting hole, and the first step of the lower end of the outer conductor is pressed into the first step groove and fastened. The riveting piece of the lower end of the outer conductor is riveted and fixed in the riveting groove to prevent it from falling off.

[0012] Furthermore, in the above technical solution, the inner wall of the first step groove is provided with at least one first plane, and the outer side of the first step is provided with a second plane, which is assembled with the first plane.

[0013] Furthermore, in the above technical solution, a groove is formed between the lower periphery of the outer conductor, the riveting piece, and the inner wall of the riveting groove. The groove is filled with waterproof adhesive to form a first sealing adhesive and achieves filling and sealing.

[0014] Furthermore, in the above technical solution, a second sealing colloid is formed between the lower end face of the insulator, the inner wall of the outer conductor, and the outer surface of the center pin by injecting waterproof adhesive, thereby achieving filling and sealing.

[0015] Furthermore, in the above technical solution, the outer conductor is dotted inward along its outer side to form protrusions on its inner wall, and these protrusions are engaged with the outer surface of the insulator.

[0016] Furthermore, in the above technical solution, the outer conductor is die-cast, the metal shell is made by cold heading or stretching, and a number of positioning cylinders are provided in the middle of the upper surface of the metal shell; the plastic shell is integrally molded from plastic, and a number of anti-foolproof positioning ribs are formed on its exterior.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0018] 1. The connector is designed separately from the metal shell, especially the outer conductor, which is designed separately from the metal shell, that is, two independent components, which are fixed together by assembly later. Since the metal shell and the outer conductor are separate structures, they are manufactured separately. Compared with the manufacturing of the metal shell and the outer conductor as an integral structure, it is more convenient to manufacture. In addition, the mold used for die casting of the outer conductor is relatively simpler and the cost is lower, which helps to improve market competitiveness.

[0019] 2. The connector also includes a colored plastic shell fitted around the outer conductor, with a locking mechanism on the outside of the plastic shell. After the plastic shell and the outer conductor are manufactured separately, plastic shells of different colors can be fitted around the outer conductor to form connectors of different colors, achieving the purpose of color changing. It is both fun and foolproof. By assembling and fixing the connector to the metal shell with the locking mechanism on the outside of the plastic shell facing different directions, the locking position can be changed to meet different usage requirements. It is also very convenient to use, meeting the needs of consumers. Attached image description:

[0032] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0033] See Figure 3-12 As shown, a metal camera back cover with interchangeable snaps and colors is provided. It includes a metal housing 2 and a connector 300 fixed to the metal housing 2 by assembly. The upper part of the connector 300 protrudes from the upper surface of the metal housing 2 for mating with a wire connector, and the lower part of the connector 300 extends into the interior of the metal housing 2 for mating with a board connector on a PCB board inside the metal housing 2 to achieve communication.

[0034] The connector 300 includes an outer conductor 3 assembled and fixed to a metal housing 2, an insulator 5 installed and fixed inside the outer conductor 3, a center pin 4 disposed inside the insulator 5, and a colored plastic shell 6 sleeved around the outer conductor 3. A matching slot 60 is formed between the plastic shell 6 and the outer conductor 3, and an outwardly protruding latch 61 is provided on the outside of the plastic shell 6. In other words, the connector 300 is designed separately from the metal housing 2, especially the outer conductor 3, which are two independent components that are later fixed together by assembly. Because the metal housing 2 and the outer conductor 3 are separate structures, they are manufactured separately, facilitating the use of different manufacturing processes. The relatively complex outer conductor 3 can be die-cast, while the relatively simple metal housing 2 can be cold-forged or drawn. This is more convenient to manufacture than manufacturing a one-piece structure where the metal housing and outer conductor are integrated. Furthermore, the outer conductor can be die-cast. The molds used for casting are relatively simpler and lower in cost, which helps to improve market competitiveness. In addition, the connector 300 includes a colored plastic shell 6 fitted around the outer conductor 3, and the plastic shell 6 has a locking buckle 61 on its exterior. After the plastic shell 6 and the outer conductor 3 are manufactured separately, different colored plastic shells 6 can be fitted around the outer conductor 3 to form connectors 300 of different colors, achieving the purpose of color changing, and its fun and foolproof features are excellent. The connector 300 is assembled and fixed to the metal shell 2 by aligning the locking buckles 61 on the exterior of the plastic shell 6 with different orientations, such as... Figure 3 , 10 As shown in Figures 11 and 12, the purpose of changing the latch position is achieved to meet different usage requirements, and it is extremely convenient to use to meet consumer needs. Even later, when it is necessary to change the direction of the latch 61 on the outside of the plastic shell 6, that is, to change the latch position, the connector 300 can be disassembled relative to the metal shell 2, and then the orientation of the latch 61 of the plastic shell 6 can be adjusted before it is reassembled and fixed onto the metal shell 2. This also achieves the purpose of changing the latch position. Furthermore, the purpose of changing the color can be achieved by assembling and fixing the connector 300 with different colored plastic shells 6 onto the metal shell 2.

[0035] The assembly structure of the plastic shell 6 and the outer conductor 3 is as follows:

[0036] The upper end of the plastic shell 6 is provided with a stepped groove 62. The plastic shell 6 has a through hole 63 that passes through the stepped groove 62 along its lower end. The middle part of the outer conductor 3 is fixed in the through hole 63, and the upper end of the outer conductor 3 extends into the stepped groove 62 and forms the matching slot 60 with the stepped groove 62. The lower end of the plastic shell 6 also abuts against the upper end of the first step 32 formed in the middle part of the outer conductor 3.

[0037] Specifically, the outer conductor 3 has a stop step 311 formed in the middle and a buckle body 312 located above the stop step 311; correspondingly, the lower part of the through hole 63 is provided with a limiting groove 631 and the upper part of the through hole 63 is provided with a locking groove 632. The stop step 311 abuts against the lower end of the limiting groove 631, and the buckle body 312 passes through the through hole 63 to be locked with the locking groove 632, thereby forming a locking structure so that the plastic shell 6 and the outer conductor 3 are stably assembled.

[0038] In addition, to further improve the stability of the assembly structure, the following design was made: several sets of claw buckles 313 are formed on the outer periphery of the middle part of the outer conductor 3, with two claw buckles 313 in each set, which are symmetrically distributed; a limiting protrusion 633 is also provided at the lower part of the through hole 63, which is inserted between the two claw buckles 313, thereby further improving the stability of the assembly structure and making the separation force between the plastic shell 6 and the outer conductor 3 reach more than 110N; in addition, it can also prevent the plastic shell 6 and the outer conductor 3 from rotating relative to each other in the circumferential direction, thereby improving product quality.

[0039] The following provides a detailed description of the assembly structure between the outer conductor 3 and the metal casing 2:

[0040] The metal casing 2 is provided with a mounting hole 211 that runs through its upper and lower ends. The upper and lower ends of the mounting hole 211 are respectively provided with a first step groove 212 and a riveting groove 213. The lower end of the outer conductor 3 passes through the mounting hole 211, and the first step 32 of the lower end of the outer conductor 3 is pressed into the first step groove 212 and tightened. This can prevent the outer conductor 3 from being pushed further into the metal casing 2. The riveting piece 33 at the lower end of the outer conductor 3 is riveted and fixed in the riveting groove 213 to prevent it from falling off, thus achieving a clamping function from the front and back. This can prevent the outer conductor 3 from accidentally falling off the metal casing 2. After the riveting piece 33 is riveted and fixed in the riveting groove 213, it can make the separation force between the outer conductor and the metal casing reach more than 110N, thereby achieving a stronger anti-detachment function.

[0041] Furthermore, to improve the stability of the assembly between the outer conductor 3 and the metal casing 2, and to achieve foolproof and anti-rotation effects, the following design is made: At least one first plane 214 is provided on the inner wall of the first stepped groove 212, and a second plane 321 is provided on the outer side of the first step 32. The second plane 321 is mated with the first plane 214. That is, the first plane 214 of the first stepped groove 212 and the second plane 321 of the outer conductor 3 are uniquely paired, with only one installation direction. This achieves the purpose of foolproofing, better guiding the installation direction, and ensuring assembly efficiency. When the outer conductor 3 and the metal casing 2 are assembled, the second plane 321 mates with the first plane 214, which prevents rotation and makes the assembly structure more stable.

[0042] A groove is formed between the lower periphery of the outer conductor 3, the riveting piece 33, and the inner wall of the riveting groove 213. This groove is filled with waterproof adhesive to form a first sealing colloid 34, achieving a complete seal. This first sealing colloid 34 not only provides excellent sealing and waterproofing but also improves the stability of the assembly structure between the outer conductor 3 and the metal casing 2. Furthermore, the first sealing colloid 34 completely fills the riveting groove 213, making its lower end face flush with the plane of the opening of the riveting groove 213, thus improving aesthetics.

[0043] A second sealing compound 35 is formed between the lower end face of the insulator 5, the inner wall of the outer conductor 3, and the outer surface of the center pin 4 by injecting waterproof adhesive, thereby achieving a filling and sealing effect and improving the sealing and waterproofing effect of this utility model. In addition, the second sealing compound 35 improves / guarantees the centering accuracy of the center pin 4 installation. Furthermore, in some other embodiments, when the board-end connector on the PCB board is inserted into the lower end of the outer conductor 3 and connected by the center pin 4, the end of the board-end connector contacts the second sealing compound 35, achieving the effect of stopping insertion and further simplifying assembly.

[0044] The outer conductor 3 is dotted inward along its outer side to form protrusions 36 on its inner wall. These protrusions 36 are engaged with the outer surface of the insulator 5, thereby enhancing the tight fit between the outer conductor 3 and the insulator 5. This effectively prevents the insulator 5 from accidentally coming off relative to the outer conductor 3 and improves the product's service life.

[0045] The outer conductor 3 is die-cast, and the metal shell 2 is made by cold heading or stretching. The upper surface of the metal shell 2 is also provided with several positioning cylinders 20, which are used for insertion and positioning in the positioning groove on the mounting interface. The plastic shell 6 is integrally molded from plastic, and its exterior is also formed with several anti-foolproof positioning ribs 64. The anti-foolproof positioning ribs 64 are inserted and limited with the mating connector to achieve the functions of anti-foolproofing and positioning.

[0046] In summary, the connector 300 is designed separately from the metal shell 2, and in particular, the outer conductor 3 is designed separately from the metal shell 2, i.e., they are two independent components, which are then fixed together by assembly. Since the metal shell 2 and the outer conductor 3 are separate structures, they are manufactured separately, which is more convenient than manufacturing a one-piece structure. The molds used for die-casting the outer conductor are also simpler and less expensive, which helps to improve market competitiveness. In addition, the connector 300 also includes a colored plastic shell 6 that is fitted around the outer conductor 3, and the plastic shell 6 has a locking buckle 61 on its outside. After the plastic shell 6 and the outer conductor 3 are manufactured separately, different colored plastic shells 6 can be fitted around the outer conductor 3 to form connectors 300 of different colors, achieving the purpose of color changing, and its fun and foolproof features are excellent. By assembling and fixing the connector 300 to the metal shell 2 with different orientations of the locking buckle 61 on the outside of the plastic shell 6, the buckle position can be changed to meet different usage requirements, and it is extremely convenient to use, thus meeting consumer requirements.
