Description

Technical Field

[0001] This invention relates to the field of vehicle vision system technology, specifically a vehicle vision navigation blind spot filling device based on a multi-lens array. Background Technology

[0002] With the rapid development of automotive intelligence and connectivity technologies, in-vehicle vision systems are playing an increasingly important role in navigation, driver assistance, parking, and active safety. Traditional in-vehicle cameras are typically positioned near the front, rear, and side mirrors to record driving images or provide reversing images. However, due to limitations in installation location and the fixed angle of view of a single camera, blind spots around the vehicle, especially the low areas near the sides, the front and rear, and structures such as the A-pillars and B-pillars, are often difficult to effectively cover. The existence of these blind spots poses potential safety risks to scenarios such as low-speed maneuvering in complex road conditions, navigating narrow roads, and automatic parking.

[0003] To expand the field of view, some solutions attempt to use wide-angle or fisheye lenses. However, while these lenses offer a wide field of view, they inevitably introduce severe image distortion, affecting the accuracy of image recognition and the driver's intuitive judgment. Other solutions employ multiple cameras positioned at different locations on the vehicle body, using image stitching technology to synthesize a panoramic image. However, such systems typically require complex calibration processes, and the alignment of the fields of view between cameras is easily affected by factors such as vehicle vibration and temperature changes, leading to errors or misalignments. Furthermore, the system wiring is complex and costly. In addition, the viewing angle of existing vehicle cameras is usually fixed after installation, making it difficult to fine-tune according to the installation position of different vehicle models or the habits of different drivers, resulting in poor blind spot coverage. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle-mounted visual navigation blind spot compensation device based on a multi-lens array. This device, by integrating a multi-lens array with a high-precision mechanical adjustment mechanism, can achieve blind spot compensation around the vehicle without blind spots, and features stable installation, flexible and precise angle adjustment, good sealing, dustproof and waterproof performance, and easy maintenance.

[0005] To address the above problems, the present invention provides a vehicle-mounted visual navigation blind spot filling device based on a multi-lens array.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a vehicle-mounted visual navigation blind spot filling device based on a multi-lens array, the structure of which includes an adjustment device and a blind spot filling device, wherein the adjustment device is detachably installed on the top of the blind spot filling device, the two are coaxially arranged and their connecting surfaces are tightly fitted.

[0007] The blind spot compensation device includes a housing, inside which a control module is fixedly embedded. The control module is electrically connected to an external vehicle navigation system and can receive, process, and transmit image signals. The housing has symmetrically arranged 45-degree inclined surfaces on both sides, which are polished to reduce debris adhesion. Multi-lens cameras are embedded at the bottom of the housing and on the two inclined surfaces. Each camera is electrically connected to the control module, and the shooting range of the multi-lens array is interconnected, eliminating blind spots and enabling omnidirectional blind spot coverage around the vehicle during in-vehicle navigation.

[0008] The above technical solution involves three cameras positioned at the bottom and sides of the vehicle's slope. By precisely calculating the installation angles, their fields of view are seamlessly connected, forming a composite field of view that covers over 180° horizontally and the near-ground area of ​​the vehicle vertically. The control module is responsible for real-time processing, distortion correction, and stitching and fusion of the images, ultimately outputting a continuous, distortion-free panoramic or wide-angle blind-spot-filling image, directly supplied to the vehicle's navigation or display system. The polished surface of the housing effectively reduces the adhesion of mud, water, and dust, keeping the lens clean and improving image quality in adverse weather conditions.

[0009] The blind spot filling device also includes a rotating base for adjusting the horizontal angle. The rotating base is coaxially fixedly installed at the bottom of the adjusting device, and a positioning structure is provided between the rotating base and the adjusting device to ensure rotation accuracy. The bottom of the rotating base is fixedly connected to the outer shell by a high-strength thread, and a sealing gasket is provided at the threaded connection to achieve dustproof and waterproof sealing.

[0010] Through the above technical solution: the rotating seat, as the core component for the horizontal rotation of the blind spot compensation device, allows the orientation of the entire camera array to be precisely adjusted in the horizontal plane. The positioning structure between it and the adjustment device ensures the stability of the rotation center and avoids shaking. The high-strength threaded connection with the outer shell ensures the mechanical strength of the overall structure. The sealing gasket effectively isolates the control module and circuit inside the outer shell from the harsh external vehicle environment, improving the reliability and service life of the device. The adjustment device includes an installation structure for fixed connection with the vehicle components.

[0011] The above technical solution provides a stable connection interface between the entire device and the vehicle body, which is the basis for the device to remain stable in the vibration environment of vehicle driving.

[0012] The mounting structure includes a fixed base for supporting the overall structure. The fixed base is rotatably connected to the mounting base via a high-precision rotating shaft. Wear-resistant bushings are provided at the connection points between the rotating shaft and the fixed base and the mounting base to reduce rotational wear and ensure smooth rotation. The top front end of the fixed base has an adjustment structure for adjusting the pitch angle of the mounting base. The bottom of the adjustment structure is rotatably connected to a slot at the front end of the mounting base. The fixed base has symmetrically arranged fixing screw holes on both sides. The fixing screw holes have a countersunk structure, which facilitates the insertion of fixing bolts without protruding from the surface of the fixed base. The top two sides of the fixed base also have symmetrically arranged protrusions. The height of the protrusions is higher than the height of the adjustment structure extending upwards from the fixed base, providing sufficient operating space for the adjustment operation and avoiding interference during adjustment.

[0013] Through the above technical solution: the mounting base is firmly installed on the vehicle body through the fixing screw holes on both sides. The mounting base is pivotally connected to the mounting base in the pitch direction through a high-precision rotating shaft. The wear-resistant bushing extends the service life of the rotating shaft and ensures smooth rotation. The raised design provides space for the operation of the adjustment structure and prevents tools or hands from interfering with the mounting base body during adjustment. The countersunk screw holes ensure that the bolt heads do not protrude after installation, resulting in a neat appearance and preventing accidental scratches.

[0014] A servo motor is fixedly embedded inside the mounting base. The output shaft of the servo motor passes through the bottom of the mounting base and precisely meshes with the gear on the top of the rotating base to ensure the rotation accuracy of the rotating base.

[0015] The above technical solution involves a servo motor receiving signals from the vehicle control unit or manual control, driving the output shaft to rotate, and then using gear transmission to precisely rotate the rotating base and the entire blind spot compensation device in the horizontal plane. The servo motor features high control precision and fast response speed, enabling stepless and precise positioning of the horizontal angle to meet the optimal viewing angle adjustment requirements in different scenarios.

[0016] The servo motor is a DC servo motor, which is compatible with the vehicle power supply specifications and can achieve precise forward and reverse rotation control.

[0017] The above technical solution directly uses the vehicle's power supply, eliminating the need for additional voltage conversion, which simplifies the system power supply design. The DC servo motor is easy to reverse and achieves precise speed and position control, making it very suitable for the horizontal rotation drive requirements of this device.

[0018] The adjustment structure includes a threaded rod for manual adjustment. The bottom of the threaded rod is threadedly connected to the threaded tube to form a threaded pair. The threaded pair adopts a fine thread structure to improve the angle adaptability of the blind patching device. The threaded tube is provided with locking rods on both sides. The locking rods are integrally formed with the threaded tube. The two ends of the locking rods are respectively embedded in the grooves opened on the two side walls of the empty slot and are rotatably connected to the empty slot. The end of the locking rod is provided with a positioning ring to prevent axial displacement during rotation.

[0019] Through the above technical solution, the adjustment structure constitutes a precise pitch angle adjustment mechanism. When rotating the threaded rod, since the threaded tube is hinged to the mounting base via the clamp and cannot move axially, the threaded rod will move axially up and down relative to the threaded tube, thereby lifting or loosening the front end of the mounting base. This allows the mounting base, along with the blind spot repair device, to adjust the pitch angle around a high-precision rotating shaft. The fine thread provides a smaller adjustment increment, enabling fine-tuning of the pitch angle and allowing the device to more accurately adapt to the installation position and visibility requirements of different vehicle models. The hinged connection between the clamp and the slot, as well as the design of the positioning ring, ensures that the connection point of the adjustment structure is stable under stress, preventing it from falling off or shifting.

[0020] A knob is fixedly provided on the top of the threaded rod. The surface of the knob has anti-slip texture to increase the friction between the hand and the knob, making it easy for the operator to adjust manually. The knob and the threaded rod are fixed by welding. The weld is flat and smooth to ensure the connection strength. The outer diameter of the knob is larger than the outer diameter of the threaded rod, making it easy to hold and operate.

[0021] Through the above technical solution, the knob provides a convenient manual operation interface. The anti-slip texture and large outer diameter design allow for easy adjustment even with wet hands or while wearing gloves. Welding ensures a firm connection between the knob and the threaded rod, capable of withstanding the torque of repeated adjustments.

[0022] The rotating base includes a rotating block for achieving rotation. A protrusion is evenly provided on the side end of the rotating block. The protrusion is integrally formed with the rotating block. The protrusion engages with a slot opened at the bottom of the mounting base to form a circumferential positioning structure, preventing radial displacement of the rotating block during rotation. A top cover is fixedly provided at the bottom of the rotating block. The top cover and the rotating block are sealed together with sealant. A threaded block is fixedly provided inside the top cover. The threaded block is integrally formed with the top cover. The threaded block and the internal thread opened at the top of the outer shell form a threaded pair, realizing a detachable connection between the rotating base and the outer shell, which is convenient for later maintenance and repair.

[0023] Through the above technical solution: the protrusion on the rotating block cooperates with the slot inside the mounting base, which plays a guiding and radial limiting role when the servo motor drives the rotation, preventing the rotating block from swaying and ensuring smooth rotation and high concentricity. The top cover is sealed to the rotating block to prevent moisture from entering the upper adjustment device. The threaded connection between the threaded block and the outer shell allows the main body of the blind spot repair device to be easily removed from the rotating base for lens cleaning, module replacement or fault repair, which greatly improves the convenience of maintenance.

[0024] The threaded connection between the threaded block and the outer shell is equipped with a sealing gasket. The sealing gasket is made of nitrile rubber, which has good dustproof, waterproof and aging resistance properties, and can effectively protect the control module inside the outer shell from the influence of the complex vehicle environment.

[0025] Through the above technical solution, the nitrile rubber sealing gasket is compressed during thread tightening, filling the tiny gaps between the threaded parts and forming a reliable sealing barrier. Its oil resistance and aging resistance ensure that the sealing performance will not significantly decrease under harsh environments such as long-term high temperature, vibration, and contact with automotive fluids, thus reliably protecting the internal precision electronic components. Beneficial effects

[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses an array of three cameras arranged on the bottom and two side slopes to achieve full coverage monitoring of the vehicle's surroundings, especially traditional blind spots, through precise angle calibration and image processing, effectively improving driving and parking safety.

[0027] 2. This invention achieves independent, precise, and stepless adjustment of the blind spot coverage angle in both the horizontal and vertical directions through a servo motor-driven horizontal rotation mechanism and a manually adjustable fine-thread pitch mechanism. It can perfectly adapt to different vehicle models and installation positions to achieve the best blind spot coverage effect.

[0028] 3. The device of the present invention adopts a modular design, and each connection part adopts high-strength threads, positioning structure and wear-resistant bushings to ensure the overall structural stability and motion accuracy under vehicle vibration environment.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example: Please refer to Figure 1 , Figure 2 This invention provides a vehicle-mounted visual navigation blind spot compensation device based on a multi-lens array, consisting of two main parts: an adjustment device 1 and a blind spot compensation device 2. The adjustment device 1 is responsible for connecting to the vehicle body and providing angle adjustment functions with two degrees of freedom: horizontal and pitch; the blind spot compensation device 2 integrates a multi-camera array and an image processing unit, responsible for image acquisition and processing.

[0038] Please see Figure 3 First, determine the installation location based on the vehicle model and the area that needs to be filled. Place the fixing seat 111 of the adjustment device 1 onto the selected vehicle body plane. Use the appropriate bolts to pass through the countersunk fixing screw holes 113 on both sides of the fixing seat 111 to firmly lock the fixing seat 111 onto the vehicle body. Due to the countersunk structure, the bolt heads will not protrude, resulting in a flat and safe appearance.

[0039] Please see Figures 3 to 5After the device is fixed, the viewing angle needs to be initially adjusted. The operator holds the knob 1143 on the top of the adjustment structure 114. The surface of the knob 1143 is provided with anti-slip texture for easy application of force. Rotating the knob 1143 causes the threaded rod 1141, which is welded and fixed to it, to rotate. The threaded rod 1141 and the threaded tube 1142 are connected by a fine thread pair. The threaded tube 1142 is hinged in the empty groove 117 at the front end of the mounting base 112 by the locking rods 1144 integrally formed on both sides. The positioning ring at the end of the locking rod 1144 prevents its axial movement. Therefore, when the threaded rod 1141 is rotated, the threaded rod 1141 will move up and down axially relative to the threaded tube 1142.

[0040] The bottom end of the threaded rod 1141 rests against the lower edge of the slot 117 or is connected via a bearing. When the threaded rod 1141 is screwed out downwards, its top end pushes the front end of the mounting base 112 downwards; conversely, when screwed in upwards, the front end of the mounting base 112 is relaxed and can be lifted upwards under its own weight or the action of an elastic element. The rear end of the mounting base 112 is hinged to the fixed base 111 via a high-precision rotating shaft 116. The wear-resistant bushings at both ends of the rotating shaft 116 ensure smooth rotation and minimal wear. In this way, the pitch angle of the mounting base 112, along with the entire blind spot filling device 2 below it, can be manually and precisely adjusted. The protrusions 115 on both sides of the top of the fixed base 111 provide sufficient space for the rotation and operation of the knob 1143, avoiding interference. After adjustment to the desired pitch angle, the angle is maintained by the self-locking property of the threaded pair.

[0041] Please see Figure 2 , Figure 6 A DC servo motor 13 is embedded inside the mounting base 112. The power cable of the servo motor 13 is connected to the vehicle power supply and control signal line. When the vehicle system needs to adjust the horizontal direction of the blind spot compensation field of vision, the control unit sends a command to the servo motor 13, and the output shaft of the servo motor 13 begins to rotate. The pinion at the end of the output shaft precisely meshes with the gear 242 on the top of the rotating seat 24, thereby driving the rotating seat 24 to rotate horizontally within the bottom cavity of the mounting base 112. A protrusion 243 is provided on the side of the rotating block 241 of the rotating seat 24. The protrusion 243 is embedded in the corresponding arc-shaped groove at the bottom of the mounting base 112. The cooperation between the protrusion 243 and the groove plays the role of circumferential guidance and radial limiting, ensuring that the rotating seat 24 is stable in the center during rotation without radial wobble, thus ensuring rotational accuracy. The servo motor 13 can precisely control the rotation angle and speed to achieve arbitrary angle positioning in the horizontal direction.

[0042] The housing 21 of the blind spot filling device 2 is tightly screwed into the threaded block 245 at the bottom of the rotating seat 24 via the internal thread at its top. The connection is equipped with a nitrile rubber sealing gasket to ensure waterproof and dustproof protection. The control module 23 is fixed inside the housing 21, which is connected to the vehicle navigation host or display system via a cable.

[0043] On the bottom plane of the housing 21 and the two symmetrical, 45-degree inclined polished bevels, a camera 22 is embedded in each of them. The lenses of the three cameras 22 all face outward and are precisely optically designed and positioned to ensure that their field of view can be seamlessly connected, together covering a wide area in front of / behind the vehicle and on both sides near the vehicle body, eliminating traditional blind spots. All cameras 22 are electrically connected to the control module 23.

[0044] When the vehicle is driving or parked, the three cameras 22 simultaneously collect image data and transmit it to the control module 23. The control module 23 has a built-in image processing chip. First, it corrects the inherent distortion of each camera lens. Then, according to the pre-calibrated parameters, it performs real-time stitching and fusion processing on the three images to generate a continuous, distortion-free, and ultra-wide blind spot coverage view. This view can be displayed directly on the vehicle's central control screen or provided to automatic parking systems, blind spot monitoring systems, etc., as a basis for decision-making.

[0045] When the lens needs cleaning, the control module 23 needs upgrading, or maintenance is required, there is no need to disassemble the entire device. Simply operate at the housing 21 and loosen the connection between it and the threaded block 245 of the rotating seat 24. The entire blind spot repair device 2 can then be removed from the adjustment device 1. After maintenance, simply tighten it again. The sealing gasket will form a reliable seal again. This design greatly simplifies daily maintenance.

Various modifications and variations can be made to the present invention by those skilled in the art.
