DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art belong to the scope of protection of the utility model.

[0026] According to the embodiments of the utility model, a vehicle-mounted high-precision visual integrated navigation device is provided.

[0027] As Figures 1-4 shown, a vehicle-mounted high-precision visual integrated navigation device comprises a bottom shell 1 and a cover 2 that are mutually adapted, the bottom shell 1 is internally provided with a PCB board 3, the cover 2 is internally provided with a guide block 4 at the top end, the guide block 4 is slidingly sleeved with a sliding plate 5, the sliding plate 5 is in L-shaped structure, and the sliding plate 5 is fixedly assembled with a camera 6 on one side, and the camera 6 is electrically connected with the PCB board 3.

[0028] The cover 2 is provided with a through hole 7 for adapting the camera 6 on one side, and the through hole 7 is internally provided with a glass sheet 8.

[0029] Among them, the cover 2 is further provided with a main antenna interface 12, a slave antenna interface 13 and an aviation bus interface 14 on one side, and the main antenna interface 12, the slave antenna interface 13 and the aviation bus interface 14 are electrically connected with the PCB board 3 respectively.

[0030] By means of the above-mentioned scheme, the camera 6 is assembled on the sliding plate 5 in L-shaped structure, and the sliding plate 5 is slidingly sleeved on the guide block 4, so that the camera 6 is slidingly installed and the focal length is easily adjusted, the user can flexibly adjust according to different driving scenes, and the device is convenient to install and disassemble, the operation is more convenient when the device is maintained or the camera is upgraded, the image acquisition demand in different scenes is met, the universality and applicability of the device are improved, and the application range of the device is widened.

[0031] Specifically, high-quality images provide accurate environmental information for navigation systems, which helps to improve navigation accuracy. In the automatic driving scene, it can help the vehicle to more accurately identify the road, obstacles and other vehicles, make more reasonable decisions, and ensure driving safety.

[0032] In addition, the top end of the cover 2 is provided with a plurality of rainproof edges 9. The bottom shell 1 is provided with a waterproof groove 10, and the waterproof groove 10 is provided with a waterproof rubber ring. The bottom shell 1 and the cover 2 are fixedly connected by screws, and the waterproof rubber ring is located between the bottom shell 1 and the cover 2.

[0033] The rainproof edges 9 and the waterproof rubber ring are adopted in the technical scheme, which can prevent rainwater and car washing water from flowing back, effectively prevent external moisture from entering, and prevent internal circuit mainboards, core boards and other electronic components from being short-circuited and corroded due to damp.

The PCB 3 generates a large amount of heat during operation, and if the heat cannot be dissipated in time, the performance of the PCB 3 will decrease, affecting the operation speed and stability of the device. The heat dissipation grooves 11 and the heat dissipation sticker can quickly conduct and release the heat generated by the PCB 3 to the surrounding environment, so that the device can always maintain an appropriate working temperature during long-term use, ensuring stable operation of the system, avoiding data processing errors and inaccurate positioning caused by overheating, and ensuring the reliability of the navigation device.

[0036] In addition, it should be particularly pointed out that the PCB 3 is integrated with an RH850U2A chip and integrated with a MEMS inertial sensor and a satellite receiver. The model of the MEMS inertial sensor can be SCH16T-K01, which realizes the internal gyroscope and accelerometer, and can collect the components of roll, pitch and heading of the carrier in the space coordinates. The model of the satellite receiver can be UM982, which realizes receiving satellite information of the whole system and all frequency points, and outputs RTK positioning and double-antenna directional solution information, and can still provide reliable and accurate positioning in a complex electromagnetic environment. The RH850U2A chip outputs accurate pose and positioning information.

During device maintenance or camera upgrading, the operation is more convenient, the image acquisition demand in different scenes is met, the universality and applicability of the device are improved, and the application range of the device is widened.

[0038] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
