Description

Technical Field

[0001] This utility model relates to the field of image perception devices in intelligent driving assistance systems, and specifically to an integrated structure for an in-vehicle binocular camera based on a small baseline. Background Technology

[0002] With the rapid development of intelligent driving technology, vehicle intelligent perception technology has become a research focus. The vehicle-mounted binocular camera is the core perception device for autonomous driving technology. It can detect information such as target height and distance based on the parallax principle, providing key data for intelligent driving assistance systems.

[0003] In the existing technology, the monocular module of the vehicle-mounted binocular camera has the problem of being difficult to reuse. When adjusting the baseline, the entire module needs to be redesigned and manufactured, which will increase the R&D cost and cycle. Some cameras have poor integration and structural design, large camera size, difficult assembly, and difficult waterproofing. In harsh environments, the camera is prone to water ingress, which affects its performance.

[0004] In view of this, a compact integrated structure for vehicle-mounted binocular cameras is proposed to solve the above problems. Utility Model Content

[0005] This invention addresses the technical problems existing in the prior art by providing an integrated structure for a vehicle-mounted binocular camera based on a small baseline. The technical solution of this invention to solve the aforementioned technical problems is as follows:

[0006] An integrated structure for a vehicle-mounted binocular camera based on a small baseline includes:

[0007] A rear housing bracket, wherein at least two mounting slots are provided on the rear housing bracket;

[0008] The monocular module comprises at least two camera modules, each correspondingly disposed within the mounting slot and detachably connected to the rear housing bracket. Each monocular module includes a lens mount, a lens, a monocular circuit board, and a connector. The lens mount is installed within the mounting slot, the lens is fixed to the front end of the lens mount, the monocular circuit board is installed at the rear end of the lens mount, the connector is electrically connected to the monocular circuit board, and the connector is detachably connected to the rear housing bracket.

[0009] In some embodiments, the vehicle-mounted binocular camera integration structure further includes:

[0010] A first sealing structure is disposed between the monocular module and the mounting groove, and the first sealing structure is a sealing ring.

[0011] In some embodiments, the vehicle-mounted binocular camera integration structure further includes:

[0012] The second sealing structure is disposed between the connector and the rear shell bracket, and the second sealing structure is a sealing ring.

[0013] In some embodiments, the monocular module is bolted to the rear shell bracket, and / or the connector is bolted to the rear shell bracket.

[0014] As can be seen from the above, by adjusting the mounting position and spacing of the monocular module on the rear housing bracket, binocular cameras with different baselines can be assembled, thereby achieving a compact camera design and improving the versatility of the module; by setting a sealing structure between the monocular module and the rear housing bracket and between the rear housing bracket and the connector interface, moisture can be effectively prevented from entering the interior of the vehicle-mounted binocular camera; at the same time, the detachable connection method facilitates the disassembly and assembly of the monocular module, improving the reusability of the monocular module.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0022] Reference Figure 1-2 The vehicle-mounted binocular camera integrated structure based on a small baseline provided by this utility model includes a monocular module 1, a sealing ring 2, a rear shell bracket 3, and a connector 4; wherein, the rear shell bracket 3 has at least two mounting slots, and the monocular module 1 consists of at least two monocular modules, each corresponding to one of the mounting slots, and is detachably connected to the rear shell bracket 3, and the rear shell bracket 3 provides a mounting base and protection for the monocular module 1.

[0023] In specific application scenarios, the installation position and spacing of each monocular module 1 on the rear shell bracket 3 can be flexibly adjusted according to actual needs to form binocular cameras with different baselines. After installation, the connector interface 8 of the monocular module 1 is brought out to connect with other systems of the vehicle.

[0024] Specifically, the monocular module 1 includes a lens 5 and a lens mount 6. The lens mount 6 is installed in the mounting groove of the rear shell bracket. The lens 5 is fixed to the front end of the lens mount and is used to collect external image information. The lens mount 6 provides stable support and positioning for the lens 5 to ensure stable optical performance of the lens. The monocular circuit board 7 is installed at the rear end of the lens mount 6. The monocular circuit board 7 integrates various electronic components and circuits and is responsible for processing and transmitting the image data collected by the lens. The connector 8 is electrically connected to the monocular circuit board 7. The monocular module 1 outputs the processed image signal through the interface of the connector 8. The connector 8 is detachably connected to the rear shell bracket 3.

[0025] In specific application scenarios, the monocular module 1 can be flexibly combined into binocular cameras with different baselines according to different application requirements. It has high independence and versatility, while greatly improving the reusability of the monocular module 1, reducing the cost of research and development and production, and shortening the product development cycle.

[0026] Reference Figure 2A first sealing structure exists between the monocular module 1 and the mounting slot. This first sealing structure can specifically be a sealing ring 2. The sealing ring 2 is installed at the connection between the monocular module 1 and the rear housing bracket 3, ensuring that it is installed flat and undamaged. The sealing ring 2 effectively fills the gap between the monocular module 1 and the rear housing bracket 3, preventing moisture from entering the vehicle-mounted binocular camera from the connection point. Theoretically, the first sealing structure is not limited to the sealing ring 2; it can also be other structures capable of achieving a seal, such as sealant.

[0027] Reference Figure 2 A second sealing structure exists between the connector 4 and the rear seat bracket 3. This second sealing structure can specifically be the sealing ring. Installing the sealing ring at the connection between the rear seat bracket 3 and the connector 4 further prevents moisture from entering the vehicle-mounted binocular camera through the connector 4, thereby improving the overall waterproof performance of the vehicle-mounted binocular camera. Theoretically, the second sealing structure is not limited to the sealing ring 2; it can also be other structures capable of achieving a seal, such as sealant.

[0028] In specific application scenarios, by setting sealing rings 2 between the monocular module 1 and the rear shell bracket 3 and between the rear shell bracket 3 and the connector 4, a double waterproof barrier is formed, which effectively prevents moisture from entering the interior of the vehicle-mounted binocular camera, ensuring that the vehicle-mounted binocular camera can still work normally in harsh environments such as humid and rainy conditions, and extending the service life of the vehicle-mounted binocular camera.

[0029] The aforementioned monocular module 1 is bolted to the rear shell bracket 3, and / or the connector 4 is bolted to the rear shell bracket 3.

[0030] In specific application scenarios, the monocular module 1 and the rear shell bracket 3 are connected by bolts to ensure that the monocular module 1 is firmly installed and accurately positioned. The bolted connection between the monocular module 1 and the rear shell bracket 3, and / or the bolted connection between the connector 4 and the rear shell bracket 3, reduces the difficulty and complexity of assembly, improves production efficiency, and thus reduces labor costs and assembly time. Theoretically, the connection between the monocular module and the rear shell bracket, and between the connector and the rear shell bracket, is not limited to bolted connections; other detachable connection structures such as snap-fit ​​connections can also be used.

[0031] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
