Description

Technical Field

[0001] This utility model relates to the field of vehicle cameras, and in particular to a rear cover for a vehicle camera. Background Technology

[0002] As the core sensing device for intelligent driving and in-vehicle monitoring, the number of in-vehicle cameras installed has increased explosively with the improvement of ADAS assisted driving level. These "eyes of autonomous driving" need to be adapted to the installation requirements of multiple scenarios such as forward vision, surround vision, and in-vehicle monitoring. As a key structure to protect the internal image sensors and lens modules, the ease of disassembly and assembly of the rear cover directly affects the assembly efficiency and maintenance cost of the camera.

[0003] In existing technologies, traditional vehicle camera back covers use either screw fixing and tool-requiring disassembly or traditional quick-release clips for single-point pressing and locking. In actual use, if the device is fixed with screws and requires tools, the entire installation and disassembly process is cumbersome and cannot meet the requirements for quick installation and disassembly. With traditional quick-release clips, the back cover is prone to loosening after long-term vehicle vibration and the clips may crack in low-temperature environments. Therefore, it is necessary to propose a new type of vehicle camera back cover to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle camera rear cover to solve the problems of the traditional vehicle camera rear cover "screw fixing + tool disassembly and assembly" method being cumbersome to operate, unable to meet the needs of quick disassembly and installation, and the traditional quick-release buckle being prone to loosening after long-term vehicle vibration and easy to crack in low temperature environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vehicle camera rear cover, comprising a vehicle camera housing, wherein a first fixing groove is formed on the outer end face of the vehicle camera housing, a first sealing rubber ring is fixedly connected in the groove of the first fixing groove, a metal post is fixedly connected on the outer end face of the vehicle camera housing, a rectangular baffle is fixedly connected on the end face of the metal post away from the vehicle camera housing, and a stepped mounting groove is formed inside the vehicle camera housing; The stepped mounting groove has a vehicle camera rear cover body inserted into its groove wall. A rectangular groove runs through the side of the vehicle camera rear cover body away from the vehicle camera housing, and an arc-shaped groove runs through the side of the vehicle camera rear cover body away from the vehicle camera housing. A magnet is fixedly connected to the end face of the arc-shaped groove away from the rectangular groove. The rectangular groove and the arc-shaped groove are interconnected. There are four sets of rectangular grooves, arc-shaped grooves, and magnets, and the four sets of rectangular grooves, arc-shaped grooves, and magnets are evenly distributed around the axis of the vehicle camera rear cover body.

[0006] Preferably, the side of the rectangular baffle closest to the vehicle camera housing abuts against the side of the vehicle camera rear cover body furthest from the vehicle camera housing.

[0007] Preferably, the rectangular groove and the rectangular baffle have the same cross-sectional size.

[0008] Preferably, the end face of the first sealing rubber ring away from the vehicle camera housing abuts against the side of the vehicle camera rear cover body close to the vehicle camera housing.

[0009] Preferably, a second sealing rubber ring is fixedly connected to the side of the vehicle camera rear cover body away from the axis of the vehicle camera housing, and the second sealing rubber ring abuts against the groove wall of the stepped mounting groove.

[0010] Preferably, a third sealing rubber ring is fixedly connected to the end face of the vehicle camera rear cover body away from the rectangular baffle, and the third sealing rubber ring abuts against the groove wall of the stepped mounting groove.

[0011] The technical advantages of this utility model are as follows: The rear cover is quickly locked using a combination of metal pillars, rectangular baffles, rectangular slots, arc-shaped slots, and magnets. These four evenly distributed locking structures distribute force in four directions, avoiding the vibration-induced loosening problem caused by concentrated force in traditional single-point latches. This improves the durability of the rear cover under different temperature conditions. Furthermore, by using the rectangular baffles, rectangular slots, and arc-shaped slots, the rear cover body can be pulled out of the stepped mounting slot for easy disassembly, requiring no tools and reducing time and labor costs for later maintenance. The second, third, and first sealing rubber rings form a "three-sided sealing" system, significantly improving the protection level of the camera housing. Even in humid environments such as vehicle wading through water or rain, it effectively protects internal electronic components and extends the camera's lifespan. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-5 As shown, this utility model provides a vehicle camera rear cover that solves the problems of cumbersome operation and inability to meet the needs of quick disassembly and installation of traditional vehicle camera rear covers by "screw fixing + tool disassembly and installation", as well as the problems of traditional quick-release buckles being prone to loosening after long-term vehicle vibration and being prone to brittleness in low temperature environment. Through structural optimization, it achieves quick disassembly and installation without tools, takes into account connection stability and environmental adaptability, and strengthens the sealing and protection effect. It is suitable for various vehicle camera rear cover assembly scenarios.

[0020] The core of this vehicle camera rear cover includes a vehicle camera housing 1 and a vehicle camera rear cover body 2. The two are quickly assembled and stably connected through an adapter structure. The vehicle camera housing 1 serves as the mounting carrier for the core camera component. Its outer end face has a first fixing groove. The first sealing rubber ring 7, which is fixedly connected in the groove, not only fills the gap between the housing and the rear cover body, preventing external dust and moisture from entering the housing and avoiding moisture or contamination of the internal electronic components, but also has an elastic pushing function. The first sealing rubber ring 7 extends out of the outer end face of the vehicle camera housing 1. During installation, it can push the vehicle camera rear cover body 2 to move through its own elasticity, always keeping the side of the rectangular baffle 6 close to the housing in contact with the side of the rear cover body away from the housing, eliminating the gap between the two, preventing the rear cover from shifting during vehicle vibration, and further improving the connection stability.

[0021] The metal post 5 and the rectangular baffle 6, which are fixedly connected to the outer end face of the vehicle camera housing 1, constitute a positioning and limiting component. The metal post 5 provides axial support, while the rectangular baffle 6 serves as a key positioning component for the rear cover installation. Its side close to the housing abuts against the side of the rear cover body away from the housing. Combined with the elastic force of the first sealing rubber ring 7, it forms a bidirectional limiting effect to prevent the rear cover from moving axially. At the same time, the stepped mounting groove 11 opened inside the housing provides a precise insertion space for the rear cover body. The stepped structure can limit the insertion depth of the rear cover body, ensuring that the installation position is consistent each time and improving assembly accuracy.

[0022] To address the shortcomings of traditional quick-release clips with single-point locking, the main body 2 of the vehicle camera rear cover is designed with four sets of rectangular grooves 3, arc-shaped grooves 4, and magnets 10 evenly distributed around its axis. The rectangular grooves 3 and arc-shaped grooves 4 are interconnected. The rectangular grooves 3 and rectangular baffles 6 have the same cross-sectional size, ensuring that the rectangular baffles 6 can be accurately embedded into the rectangular grooves 3, achieving initial positioning of the rear cover installation. The arc-shaped grooves 4 provide a path for the rotation locking of the rear cover. After the main body of the rear cover is initially positioned, the rectangular baffles 6 can slide along the arc-shaped grooves 4 during rotation until they reach the desired position. The arc-shaped groove 4 is away from the end of the rectangular groove 3. At this time, the magnet 10 fixedly connected to the end of the arc-shaped groove 4 will be attracted and attached to the rectangular baffle 6 made of metal. The back cover is quickly locked by magnetic force. The four sets of evenly distributed locking structures can distribute the force to the four directions of the back cover, avoiding the problem of vibration and loosening caused by the concentrated force of traditional single-point buckles. Moreover, the magnetic locking does not rely on the elastic deformation of plastic buckles, effectively solving the problem of traditional buckles becoming brittle and easily broken in low temperature environments, and improving the durability of the back cover in different temperature environments.

[0023] In addition, the main body 2 of the vehicle camera rear cover is equipped with a double auxiliary sealing structure: a second sealing rubber ring 8 is fixedly connected to the side away from the housing axis and abuts against the groove wall of the stepped mounting groove 11, which can prevent dust and moisture from entering from the radial gap between the rear cover and the mounting groove; a third sealing rubber ring 9 is fixedly connected to the end face away from the rectangular baffle 6 and also abuts against the groove wall of the stepped mounting groove 11, further enhancing the axial sealing effect. The second sealing rubber ring 8, the third sealing rubber ring 9 and the first sealing rubber ring 7 form a "three-sided sealing" system, which greatly improves the protection level of the camera housing. Even in humid environments such as vehicle wading through water or rainy weather, it can effectively protect the internal electronic components and extend the service life of the camera.

[0024] During installation, without the need for any tools, the staff first aligns the main body 2 of the vehicle camera rear cover with the stepped mounting groove 11 of the vehicle camera housing 1, aligning the four sets of rectangular grooves 3 on the main body of the rear cover with the four sets of rectangular baffles 6 on the outer end face of the housing; then, the main body of the rear cover is slowly pushed into the stepped mounting groove 11 until the side of the main body of the rear cover closest to the housing contacts and presses against the first sealing rubber ring 7, completing the initial positioning; then, the main body of the rear cover is rotated clockwise or in the direction set according to the actual direction of the arc groove 4, and the rectangular baffles 6 will slide smoothly along the arc groove 4. When the rectangular baffle 6 slides to the end of the arc groove 4 away from the rectangular groove 3, the magnet 10 in the arc groove 4 generates an attraction force with the metal rectangular baffle 6, firmly adsorbing and fixing the rectangular baffle 6. At the same time, the second sealing rubber ring 8 and the third sealing rubber ring 9 on the back cover body are tightly attached to the groove wall of the stepped mounting groove 11. At this time, the first sealing rubber ring 7 generates a reverse thrust due to elastic deformation, pushing the back cover body to move slightly outward, so that the side of the rectangular baffle 6 close to the shell is tightly abutted against the side of the back cover body away from the shell, completing the rapid installation of the entire back cover and improving its assembly efficiency.

[0025] Furthermore, during the disassembly process, when it is necessary to inspect, maintain, or replace the internal components of the camera, the staff only needs to hold and press the outer side of the vehicle camera rear cover body 2 with their hands, and apply rotational force in the opposite direction of the rotation direction during installation to overcome the attraction between the magnet 10 and the rectangular baffle 6, so that the rectangular baffle 6 gradually slides back to the initial position of the rectangular groove 3 along the arc groove 4; after the rectangular baffle 6 has completely returned to the rectangular groove 3, the rear cover body is pulled out from the stepped mounting groove 11 to complete the disassembly. No tools are required throughout the process, making the operation convenient and effectively reducing the time and labor costs of later maintenance.
