[0002] The automotive intelligent driving assistance system (ADAS) can provide assistance and supplement to the driver in complex traffic environments and vehicle control processes, and is one of the important technologies for active safety in modern vehicles.

[0003] However, blind spot monitoring is usually installed in the left and right rearview mirrors or other sensors to sense the road information behind and warn the driver; automatic parking uses sensors to sense the surrounding environment and road information to enable the car to automatically park without manual control.

[0004] When the vehicle is changing lanes, due to the blind spots in the rearview mirror when turning, the driver cannot fully judge the information of the vehicle behind based on the information from the rearview mirror alone, which increases the risk of collision or scratches when changing lanes. In addition, blind spots are easily generated when turning, which affects the accuracy of automatic parking. Summary of the invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide a blind spot monitoring and automatic parking device for new energy vehicles. This solution can better monitor the blind spot field of view through a telescopic and tilted field of view monitoring method, thereby providing a good field of view environment when the vehicle changes lanes, turns or automatically parks.

[0014] Furthermore, the curved component also includes a second transmission plate hinged to the slider and hinged to the bottom surface protrusion of the guide block.

[0015] The beneficial effect of adopting the above further solution is that, by providing a telescopic spring, the telescopic spring can facilitate the sliding of the sliders on both sides on the surface of the fixed rod, so that the sliders elastically support the guide block through the second transmission plate.

[0016] Furthermore, the adjustment mechanism includes a slide groove provided on the inner side wall of the installation frame and slidably matched with the outer end of the push rod; the adjustment mechanism also includes a plurality of ventilation grooves provided on the outer surface of the installation frame.

[0017] The beneficial effect of adopting the above further solution is that, by setting the slide groove, the push rod can be easily limited and guided to avoid shaking and deviation of the push rod during movement, thereby improving the stability of transmission between components.

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0035] As described in the background technology, the driver cannot fully judge the information of the rear vehicle only by the information in the rearview mirror, which increases the risk of collision or scratching the car when changing lanes, and blind spots are easily generated when turning, which will affect the accuracy of automatic parking. For this reason, this embodiment provides a blind spot monitoring and automatic parking device for new energy vehicles. The device can better monitor the blind spot field of view through a telescopic and tilted field of view monitoring method, thereby facilitating the provision of a good field of view environment when the vehicle changes lanes, turns or automatically parks.

[0036] See also Figure 1 - Figure 5 This embodiment proposes a blind spot monitoring and automatic parking device for new energy vehicles, including an inclined plate 2 located outside a vehicle body 1, a transparent cover 3 is provided on the outer surface of the inclined plate 2, and a sensing unit 4 connected to the inclined plate 2 and located in the transparent cover 3.

[0037] refer to Figures 1 to 5The transparent cover 3 is made of transparent material and is waterproof, which can prevent rainwater from remaining on the surface of the transparent cover 3 and affecting the monitoring of the surrounding blind spots by the sensing unit 4 in the transparent cover 3. The sensing unit 4 is connected to the display device in the vehicle through a connecting line, so that the dangers within the blind spot can be displayed and warned.

[0038] A sealing strip 6 is provided on the outer surface of the inclined plate 2 , and the outer surface of the sealing strip 6 is in close contact with the reserved groove on the outer surface of the automobile body 1 .

[0039] By providing the sealing strip 6, the sealing and waterproof properties between the tilting plate 2 and the automobile body 1 can be better improved, and dirt or rainwater can be prevented from entering the installation frame 501 to cause damage to the device components, thereby greatly improving the safety of the overall device.

[0040] An adjustment mechanism 5 is installed in the reserved groove on the outer surface of the automobile body 1, and the adjustment mechanism 5 includes a vertical pushing component and a curved pushing component connected to the tilting plate 2. The vertical component is used to push the tilting plate 2 and the sensing unit 4 to extend or retract in the automobile body 1, and the curved component is used to push the tilting plate 2 and the sensing unit 4 to tilt at an angle after being extended.

[0041] refer to Figures 1 to 6 The arrangement of the vertical pushing component and the curved pushing component can push the inclined plate 2 to be extended and retracted outside the automobile body 1, and after extension and retraction, the inclined plate 2 can be tilted by the curved pushing component, so that the inclined plate 2 can be tilted, and the sensing unit 4 in the inclined plate 2 can be tilted at an angle, so as to facilitate monitoring within the blind spot range.

[0042] In addition, the sensing unit 4 is mainly composed of a camera, a detection radar, and an ultrasonic sensor, and is mainly used for detecting and sensing the external environment, objects, etc. This is an existing technology and therefore will not be elaborated on.

[0043] The vertical assembly includes an electric push rod 502 connected to the mounting frame 501 , a push rod 503 connected to the output end of the electric push rod 502 , and a first transmission plate 504 rotatably connected to the push rod 503 and hinged to the tilting plate 2 .

[0044] By setting up an electric push rod 502, the output end of the electric push rod 502 pushes the push rod 503 to perform lifting and lowering movements, so that the push rod 503 can push the tilting plate 2 to move through the first transmission plate 504 during the lifting and lowering movements, and the tilting plate 2 can be stably extended and retracted due to the action of the subsequent limiting components during the movement, thereby preventing the tilting plate 2 from shaking during movement.

[0045] The vertical assembly also includes a U-shaped guide rod 505 connected to the inclined plate 2 and located in the installation frame 501. The inner wall of the installation frame 501 is fixedly connected with a fixing block 506, and a guide groove 508 is opened in the fixing block 506 and slidably cooperates with the U-shaped guide rod 505 on the same side.

[0046] By setting up the U-shaped guide rod 505, it is convenient to limit the tilting plate 2 during the telescopic movement, so that the U-shaped guide rod 505 can contact the inside of the installation frame 501, thereby limiting the tilting plate 2 and avoiding excessive left and right shaking when pushing the tilting plate 2 to move, which affects the telescopic effect. The stability of the tilting plate 2 during telescopic movement can be further improved through the action of the fixing block 506 and the guide groove 508.

[0047] The curved component includes a guide block 507 opposite to the fixed block 506 and located in the installation frame 501, and a curved guide groove 509 opened in the guide block 507 and slidably matched with the U-shaped guide rod 505 on the same side. The curved guide groove 509 is used to guide the U-shaped guide rod 505.

[0048] By setting the guide block 507, the guide block 507 can be extended and retracted synchronously with the U-shaped guide rod 505, and the guide block 507 will be limited by the sliding movement between the installation frame 501 during the extension and retraction process, thereby preventing the guide block 507 from falling and deflecting, and the guide block 507 stops extending and retracting when it is extended to the moving position.

[0049] The U-shaped guide rod 505 is guided by the curved guide groove 509 to move, and then one side of the U-shaped guide rod 505 is guided and the other side is limited, so that the tilting plate 2 can tilt, which is convenient for adjusting the angle and monitoring the blind spot when the vehicle turns.

[0050] A fixing rod 5010 is fixedly connected to the inner wall of the mounting frame 501, and the curved component also includes two sliders 5011 which are sleeved on the outer surface of the fixing rod 5010 and slidably cooperate with the fixing rod 5010, and a telescopic spring 5012 which is connected to the two sliders 5011 and sleeved on the outer surface of the fixing rod 5010, and the curved component also includes a second transmission plate 5013 which is hinged to the sliders 5011 and hinged to the bottom protrusion of the guide block 507.

[0051] By providing the telescopic spring 5012 , the telescopic spring 5012 can facilitate the sliding blocks 5011 on both sides to slide on the surface of the fixing rod 5010 , so that the sliding blocks 5011 elastically support the guide block 507 through the second transmission plate 5013 .

[0052] Therefore, when the inclined plate 2 rises, the guide block 507 can be synchronously pushed upward by the elasticity of the telescopic spring 5012, and when pushed to the top, the U-shaped guide rod 505 can be limited by the curved guide groove 509 and perform a guiding movement.

[0053] The adjusting mechanism 5 includes a slide groove 5014 formed on the inner wall of the mounting frame 501 and slidably matched with the outer end of the push rod 503 ; the adjusting mechanism 5 also includes a plurality of ventilation grooves 5015 formed on the outer surface of the mounting frame 501 .

[0054] By setting the slide groove 5014, it is possible to facilitate the limiting and guiding of the push rod 503, thereby preventing the push rod 503 from shaking and deflecting during movement, thereby improving the stability of transmission between components. The setting of the ventilation groove 5015 can better facilitate ventilation within the installation frame 501, thereby effectively reducing heat accumulation in the installation frame 501, and further improving the service life of the components of the entire device.

[0055] The adjustment mechanism 5 further includes a slide bar 5016 fixed to the inner wall of the installation frame 501 and slidably matched with the guide block 507 . The slide bar 5016 is used to keep the guide block 507 in a position-limiting guide for vertical movement.

[0056] By setting the slide bar 5016, it is possible to better facilitate the limiting guidance of the guide block 507, and to facilitate the installation and sliding of the guide block 507, so that the guide block 507 can rise and move downward stably, and then it is possible to facilitate the guidance of the U-shaped guide rod 505 through the curved guide groove 509 after rising.

[0057] Working principle:

[0058] During the process of turning or automatic parking of the car, the electric push rod 502 is first started, and the output end of the electric push rod 502 pushes the push rod 503 to rise under the limiting action of the slide groove 5014, and the push rod 503 drives the first transmission plate 504 to push the inclined plate 2, so that the inclined plate 2 drives the U-shaped guide rod 505 to move during the movement, and one side of the U-shaped guide rod 505 can stably rise at the fixed block 506 through the limiting action of the guide groove 508 during the movement, and the guide block 507 on the other side can push the guide block 507 under the elastic action of the slider 5011, the telescopic spring 5012 and the second transmission plate 5013. The guide block 507 rises synchronously, and when the U-shaped guide rod 505 on one side moves to the top of the guide groove 508, the guide block 507 rises to the top and stops, and at this time, the first transmission plate 504 pushes the inclined plate 2 to continue to rise, so that the inclined plate 2 can be guided by the U-shaped guide rod 505 on the other side under the guidance of the curved guide groove 509, so that the inclined plate 2 is tilted, so that the sensing unit 4 in the inclined plate 2 can monitor the blind spot, so as to improve the field of vision of the vehicle when turning or automatically parking, reduce the occurrence of accidents, and reduce the risk of collision with obstacles or vehicles in the blind spot.

[0059] 1. Start-up and initial outreach

[0060] When the car needs to turn or park automatically, the system first starts the electric push rod 502. The electric push rod 502 acts as a power source, and its output end starts to push the push rod 503 to move. Under the precise limit of the slide groove 5014, the push rod 503 maintains a stable upward trajectory to avoid shaking or deviation. In this process, the push rod 503 transmits power to the tilting plate 2 through the first transmission plate 504 connected thereto, so that the tilting plate 2 begins to extend outward from the inside of the car body 1.

[0061] 2. Steady rise and synchronous movement

[0062] As the inclined plate 2 extends, the U-shaped guide rod 505 thereon also starts to move. One side of the U-shaped guide rod 505 is stably raised along the fixed block 506 under the close cooperation of the guide groove 508. This design ensures the stability of the inclined plate 2 during the rising process. At the same time, the guide block 507 on the other side is elastically connected with the telescopic spring 5012 through the slider 5011, and the transmission effect of the second transmission plate 5013, so as to achieve the synchronous rise with the U-shaped guide rod 505. The existence of the telescopic spring 5012 not only provides the necessary elastic support, but also enhances the stability and response speed of the system.

[0063] 3. Tilt adjustment and field of view monitoring

[0064] When the U-shaped guide rod 505 on one side moves to the top of the guide groove 508, the guide block 507 also reaches the top of its ascending stroke and stops. At this time, the first transmission plate 504 continues to push the tilting plate 2 to rise, but due to the special guiding effect of the curved guide groove 509 on the U-shaped guide rod 505 on the other side, the tilting plate 2 begins to tilt. This tilt adjustment process enables the tilting plate 2 and its internal sensing unit 4 (including cameras, detection radars, ultrasonic sensors, etc.) to be more accurately aligned with the blind area of ​​vision. The sensing unit 4 immediately starts to work, monitoring and sensing the environment and objects in the blind area in real time, providing the driver with clear vision information.

[0065] The blind spot monitoring and automatic parking device of new energy vehicles can significantly improve the safety of vehicles during turning or automatic parking. It effectively expands the driver's field of vision and reduces the risk of collision caused by blind spots. At the same time, the device can also display and warn of detected dangerous situations in a timely manner, further improving the reliability and safety of driving.
