[0032] According to a first aspect of the embodiments of this application, a turning assist device is provided, which will be described below in conjunction with... Figures 1 to 5 Describe in detail the structure and working principle of the turning assist device.

[0033] According to the embodiments of this application, the turning assist device is used in a vehicle. The vehicle includes an A-pillar, and the turning assist device is disposed on the A-pillar. The turning assist device includes a connecting plate, a sensing plate, a first monitoring mechanism, and a second monitoring mechanism.

[0034] In one embodiment, the connecting plate is used to connect to the vehicle body, and the connecting plate has a first plate portion and a second plate portion that are perpendicular to each other. The sensing plate includes a third plate portion and a fourth plate portion that are perpendicular to each other, the third plate portion being detachably connected to the first plate portion, and the fourth plate portion being detachably connected to the second plate portion.

[0035] In one embodiment, a first monitoring mechanism is disposed on a third plate, and the first monitoring mechanism includes a plurality of first monitors, at least some of which are movable on the third plate. A second monitoring mechanism is disposed on a fourth plate, and the fourth plate includes a plurality of second monitors, at least some of which are rotatable about their own axis.

[0036] Thus, according to the turning assist device provided in this application embodiment, the turning assist device is installed on the A-pillar of the vehicle to assist the vehicle in turning. During assistance, the position of the first and second monitors is changed to expand the monitoring field of view, thereby improving the safety of turning operations. In addition, the first and second monitoring mechanisms are installed on the sensing plate, and the sensing plate and the connecting plate are detachable. Therefore, the first and second monitoring mechanisms are integrated on the sensing plate to form a pre-assembled module, which is convenient for installation and disassembly.

[0037] In this embodiment, both the first and second monitors can be, for example, cameras. The image signals captured by both can be received by the vehicle's controller, which then performs some control actions based on the image signals from the first and second monitors, as will be explained in the following description.

[0038] In the embodiments, both the connecting plate and the sensing plate are essentially right-angled plates, or approximately right-angled plates, with the term approximately right-angled plate intended to indicate that there is a rounded transition section between the two plate portions of the connecting plate (sensing plate).

[0039] In this embodiment, as an example, the motion trajectory of the first monitor capable of movement can be, for example, a straight line, and the direction of extension of the motion trajectory will be explained in detail later.

[0040] According to the turning assist device provided in the embodiments of this application, at least some of the aforementioned plurality of first monitors are capable of moving along a first horizontal direction, and the extension direction of the third plate includes the first horizontal direction.

[0041] As an example, in this embodiment, the third plate may be disposed, for example, on the side of the vehicle, and the fourth plate may be disposed, for example, on the front of the vehicle. In other words, the first monitoring mechanism is used to monitor the situation on the side of the vehicle, and the second monitoring mechanism is used to monitor the situation on the front of the vehicle.

[0042] As an example, the first horizontal direction can be, for example, the length direction of the vehicle, that is, the direction in which the vehicle travels in a straight line. As mentioned above, some of the monitors in the first monitoring mechanism move in a straight line along the first horizontal direction. For example, the first monitor can move in a straight line through a structure such as a lead screw, nut and slider, which will be explained in detail in the following description.

[0043] According to the turning assist device provided in the embodiments of this application, the first monitor moves along the side of the vehicle, thereby scanning a larger area of ​​the side of the vehicle near the A-pillar, thereby obtaining images of a larger area to reduce the blind spot of the vehicle when turning.

[0044] According to the turning assist device provided in the embodiments of this application, at least some of the aforementioned plurality of second monitors are capable of rotating about an axis extending vertically through themselves, and the extension direction of the fourth plate includes the vertical direction.

[0045] According to the turning assist device provided in the embodiments of this application, the second monitor rotates along the vertical axis, thereby increasing the area of ​​the front of the vehicle scanned by the second monitor, thereby further reducing the blind spot when the vehicle is turning.

[0046] In one embodiment, the second monitor may be mounted on a rotating shaft, which may be driven by a servo motor and rotate along the axis of the shaft, as will be described in detail later.

[0047] According to the turning assist device provided in the embodiments of this application, the turning assist device may further include a plurality of elastic members, the plurality of elastic members being disposed between the connecting plate and the sensing plate, the elastic members may have a first end and a second end opposite to each other, the first end may abut against the connecting plate, and the second end may abut against the sensing plate.

[0048] In this embodiment, the elastic element can, on the one hand, achieve pre-tightening of the sensor plate on the connecting plate by abutting against it. On the other hand, the elastic element can further compress when the sensor plate moves further toward the connecting plate due to vehicle bumps, thereby absorbing the kinetic energy of the sensor plate and preventing resonance between the sensor plate and the connecting plate. This prevents the images acquired by the first and second monitors from becoming blurred due to resonance.

[0049] According to the turning assist device provided in the embodiments of this application, the turning assist device may further include multiple buffer members, which may be arranged one-to-one with multiple elastic members, for example, arranged next to the elastic members. The buffer members are used to buffer the impact between the connecting plate and the sensing plate, thereby further avoiding the resonance situation mentioned above. As an example, the buffer member may be, for example, a damper, which uses hydraulic resistance to buffer the connecting plate and the sensing plate.

[0050] According to the turning assist device provided in the embodiments of this application, the turning assist device may further include a first prompting structure. The third plate has a first area where multiple first monitors are provided. The first prompting structure is provided at the top and bottom of the first area. As an example, the first prompting structure may be, for example, a first warning light, which can be communicatively connected to the vehicle controller and used to flash in response to the control of the vehicle controller according to the image information obtained by the first and second monitors, so as to prompt the driver.

[0051] According to the turning assist device provided in the embodiments of this application, similarly, the turning assist device may also include a second prompting structure. The fourth plate may have a second area where multiple second monitors are provided. The second prompting structure is provided at the top and bottom of the second area. As an example, the second prompting structure may be, for example, a second warning light, which can be communicatively connected to the vehicle controller and used to flash in response to the control of the vehicle controller according to the image information obtained by the first and second monitors, so as to prompt the driver.

[0052] Furthermore, according to the turning assist device provided in the embodiments of this application, the turning assist device may further include a first radar and a second radar. Multiple first monitors are arranged in two groups at intervals, with the first radar positioned between the two groups of first monitors. Similarly, multiple second monitors are arranged in two groups at intervals, with the second radar positioned between the two groups of second monitors. This further assists in monitoring turning operations through radar, and these radars can also be communicatively connected to the vehicle controller.

[0053] like Figures 1 to 5 As shown in the embodiment, this application provides a bus turning blind spot assistance device based on visual enhancement technology. As described above, the turning assistance device includes a connecting plate 1 connected to the vehicle body via a detachable connection means, such as bolts. A sensing plate 2 is installed on the side of the connecting plate 1 facing away from the vehicle body. At least one set of sliding blocks 33 are slidably assembled inside the sensing plate 2. In this embodiment, the sliding blocks 33 are used to drive a first monitor for turning monitoring assistance. At least one set of rotating plates 4 are rotatably installed inside the sensing plate 2, and a second monitor is correspondingly arranged on the rotating plates 4. By rotating the second monitor through the rotating plates 4, the turning assistance device further achieves turning monitoring assistance.

[0054] In this embodiment, the main structure of the turning assist device may include a connecting plate 1 bolted to the inside of the A-pillar of the bus. The outer edge of the connecting plate 1 may have an arc-shaped transition design to fit the contour of the vehicle body. As an example of a detachable connection method, the outer side of the connecting plate 1 may also be connected to the sensing plate 2 via a snap-fit ​​structure (for example, a male snap-fit ​​is provided on the side of the connecting plate 1 facing the sensing plate 2, and a female snap-fit ​​is provided on the side of the sensing plate 2 facing the connecting plate 1, with the corresponding male and female snap-fits engaging with each other). In this embodiment, the surface of the sensing plate 2 is covered with a transparent anti-scratch coating, and two parallel sliding grooves are formed inside the sensing plate 2, within which two sets of sliding blocks 33 are slidably assembled.

[0055] In this embodiment, the main body of the sliding block 33, i.e., the block structure, such as a cuboid block structure, can be made of aluminum alloy. In this embodiment, four sets of ball bearings are embedded at the bottom of the main body of the sliding block 33 to reduce sliding friction, and the top is connected to the monitoring board 3 via a universal joint. Two sets of rotating plates 4 are rotatably mounted at both ends of the sensing plate 2 via bearings. The rotating plates 4 can adopt a hollow structure design to reduce weight, and their rotation axis is perpendicular to the turning radius direction of the bus. When the vehicle activates the turn signal, the sliding block 33 can move along the slide groove towards the front of the vehicle, causing the monitoring board 3 to extend to the outside of the A-pillar. At the same time, the rotating plates 4 unfold outwards from the vehicle, expanding the monitoring field of view and covering the blind spot during turns through mechanical linkage.

[0056] In this embodiment, a plurality of arrayed springs 12 are connected between the connecting plate 1 and the sensing plate 2. Each spring 12 is equipped with a damper, and both ends of the connecting plate 1 are provided with a plurality of equally spaced connecting holes 11.

[0057] In this embodiment, the connection structure between the connecting plate 1 and the sensing plate 2 can be made of six arrayed springs 12, and the two ends of the springs 12 can be connected to the reinforcing ribs of the connecting plate 1 and the sensing plate 2 respectively by welding.

[0058] In this embodiment, a hydraulic damper is coaxially embedded inside the spring 12. The damper cylinder is fixed to the connecting plate 1, and the piston rod is connected to the sensing plate 2 via a floating joint. When the vehicle vibrates, the spring 12 absorbs the vibration energy of the sensing plate 2 through elastic deformation, and the damper suppresses the reciprocating oscillation of the spring 12 through the flow resistance of hydraulic oil. The two work together to prevent the monitoring board 3 from blurring due to resonance. Four sets of connecting holes 11 are opened at both ends of the connecting plate 1.

[0059] In this embodiment, the connecting hole 11 can be designed with an oblong shape to compensate for the manufacturing tolerances of the vehicle body and the connecting plate 1. The device is fixed to the vehicle body by bolts passing through the connecting hole 11. The turning assist device can ensure that the positional accuracy of the first monitoring mechanism and the second monitoring mechanism can still be maintained after long-term use.

[0060] In this embodiment, several arrays of equally spaced warning lights 21 can be provided on the upper and lower sides of the sensing plate 2, and several equally spaced radars 22 can be provided in the middle of the sensing plate 2.

[0061] In this embodiment, specifically, multiple sets of warning lights 21 can be embedded in the sensor plate 2. On the third plate, from top to bottom, there is a row of first alarm lights, namely the warning lights 21 mentioned here, a first set of first monitors, a row of first alarm lights, a first radar, a second set of first monitors, and a row of first alarm lights. On the fourth plate, from top to bottom, there is a row of second alarm lights, namely the warning lights 21 mentioned above, a first set of second monitors, a row of second alarm lights, a second radar, a second set of second monitors, and a row of second alarm lights.

[0062] In this embodiment, the warning light 21 uses an LED light source and integrates a photosensor, which can automatically adjust its brightness according to the ambient light intensity. When the monitoring system detects an obstacle in the blind spot area, the warning light 21, under the control of the vehicle control system, issues a visual warning to the driver through a high-frequency flashing mode. Three sets of millimeter-wave radars 22 are installed in the center of the sensing plate 2. The radars 22 are arranged at a 120° angle, and their beams cover the turning blind spot from the outer side of the front wheel of the bus to below the rearview mirror. The radars 22 detect the distance to obstacles by emitting frequency-modulated continuous waves. When the detected relative distance is less than a safety threshold, the warning light 21 and the vehicle voice prompt system are triggered. The linkage logic between the radars 22 and the warning light 21 is implemented through the vehicle ECU, ensuring that the driver is provided with multi-level safety warnings in complex traffic environments.

[0063] In this embodiment, at least one rotating motor 31 is installed inside the sensing plate 2. A lead screw 32 is installed at the output end of the rotating motor 31. At least one straight shaft 34 is fixedly connected inside the sensing plate 2. Sliding blocks 33 are movably sleeved on both the straight shaft 34 and the lead screw 32. A rotating motor 35 is installed on one side of one of the sliding blocks 33. A rotating shaft 351 is installed at the output end of the rotating motor 35. A monitoring plate 3 is fixedly sleeved on the outer circumferential surface of the rotating shaft 351. At least one first monitor 352 is provided on the monitoring plate 3.

[0064] In this embodiment, two sets of rotating motors 31 are installed inside the sensing plate 2. The main body of the rotating motor 31 is fixed to the reinforcing rib of the sensing plate 2 by bolts. The output shaft of the rotating motor 31 is connected to the lead screw 32 through a rigid coupling. The two ends of the lead screw 32 are rotatably connected to the sensing plate 2 through bearing seats. The bottom of the sliding block 33 has a threaded hole to form a helical drive with the lead screw 32, and the middle of the sliding block 33 has a through hole to form a sliding fit with the straight shaft 34.

[0065] In this embodiment, the two ends of the straight shaft 34 are fixed to the inner wall of the sensing plate 2 by snap rings. When the rotary motor 31 drives the lead screw 32 to rotate, the sliding block 33 translates axially along the straight shaft 34. The top of the sliding block 33 is fixed to the rotary motor 35 by bolts, and the output shaft of the rotary motor 35 is connected to the rotary shaft 351 by a shrink sleeve. The monitoring plate 3 is fixed to the end of the rotary shaft 351 by a flange. The rotary motor 35 can drive the monitoring plate 3 to rotate within a range of ±90°, adjusting the shooting angle of the first monitor 352 to adapt to the monitoring needs of different turning radii.

[0066] In this embodiment, a limiting plate 331 is fixedly connected to one side of the sliding block 33, and the limiting plate 331 is slidably assembled inside the sensing plate 2.

[0067] In this embodiment, two sets of limiting plates 331 are welded to both sides of the sliding block 33. The limiting plates 331 are made of self-lubricating nylon material to reduce sliding noise. A guide groove matching the limiting plate 331 is opened on the inner wall of the sensing plate 2. Elastic buffer pads are provided at both ends of the guide groove to prevent the sliding block 33 from exceeding the travel limit.

[0068] When the rotating motor 31 drives the lead screw 32 to rotate, the limiting plate 331 slides along the guide groove, and the mechanical constraint prevents the sliding block 33 from shifting circumferentially due to the rotation of the lead screw 32. The fit clearance between the limiting plate 331 and the guide groove is controlled within 0.1mm to ensure that the sliding block 33 can maintain the stability of the monitoring plate 3 during high-speed movement, and avoid the degradation of the image acquisition quality of the first monitor 352 due to mechanical vibration.

[0069] In this embodiment, a servo motor 41 is installed on one side of the sensing plate 2, and a transmission shaft 42 is installed at the output end of the servo motor 41. The rotating plate 4 is fixedly sleeved on the outer circumferential surface of the transmission shaft 42, and at least one second monitor 43 is installed on one side of the rotating plate 4.

[0070] Specifically, the servo motor 41 is fixed to the end of the sensing plate 2 by bolts. The output shaft of the servo motor 41 is connected to the transmission shaft 42 through a diaphragm coupling. The two ends of the transmission shaft 42 are rotatably connected to the sensing plate 2 through angular contact bearings. The rotating plate 4 is fixed to the middle of the transmission shaft 42 by a shrink-fitting connecting sleeve. When the servo motor 41 drives the transmission shaft 42 to rotate, the rotating plate 4 swings in the vertical plane.

[0071] In this embodiment, weight-reducing holes are formed on the surface of the rotating plate 4 to reduce rotational inertia, and a second monitor 43 is embedded in its outer edge. The second monitor 43 uses a wide-angle lens to cover a larger monitoring range. The servo motor 41 integrates an encoder, and closed-loop control ensures that the rotation angle accuracy of the rotating plate 4 is ≤0.1°, ensuring that the second monitor 43 can accurately target the dynamic blind spot when the bus turns. After the vehicle completes the turning operation, the rotating plate 4 automatically returns to the surface of the sensing plate 2, and excessive rotation is prevented by a mechanical limit block.

[0072] Compared with the prior art, the turning assist device provided according to the embodiments of this application, through the linkage design of the sliding block and the monitoring board, and the setting of radar and other structures, the sliding block moves along the slide groove to drive the monitoring board to extend to the outside of the A-pillar, while the rotating board unfolds outward, expanding the monitoring field of view through mechanical linkage; the radar covers the turning blind spot at a 120° angle, and triggers the high-frequency flashing of the warning light and the vehicle voice prompt when an obstacle is detected, forming a dual-channel warning of vision and hearing, ensuring that the driver receives multi-level safety feedback in complex traffic environments.

[0073] The turning assist device provided in this application significantly enhances the device's durability and environmental adaptability through the design of a spring-damper vibration suppression structure and a precise fit between the limiting plate and the guide groove. The spring absorbs vehicle vibrations through elastic deformation, while the damper suppresses the spring's reciprocating oscillations through hydraulic oil flow resistance. The two work together to prevent image blurring caused by resonance on the monitoring board. The limiting plate, made of self-lubricating nylon, controls the fit clearance with the guide groove, ensuring the sliding block maintains stable posture during high-speed movement, preventing mechanical vibration from degrading monitoring quality, and significantly extending the device's service life.

[0074] According to a second aspect of the embodiments of this application, a vehicle is provided, which includes the above-mentioned turning assist device, as well as the above-mentioned vehicle body and vehicle controller, and has the above-mentioned beneficial effects, which will not be repeated here.

[0075] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. All equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
