Technical Field

[0001] The embodiments of the present application relate to the field of vehicle driving technology, and in particular to a driving assistance device and a vehicle. Background Art

[0002] Parallel parking is a way of parking a vehicle at the edge of the road and is an important skill in driving.

[0003] When a vehicle is moving, its front wheels primarily control its trajectory. Front fenders are located above the front wheels to protect the vehicle and reduce drag. When parking sideways, the front wheels and fenders are more susceptible to damage.

[0004] Specifically, when performing parallel parking, due to the driver's limited vision, he is often unable to accurately judge the distance between the front wheels and side obstacles, which causes the front wheels, front fenders, etc. to easily scratch against side obstacles and cause damage to the vehicle.

[0039] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0044] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0045] For ease of understanding, some of the terms involved in the embodiments of this application are explained below:

[0046] Front fender: installed above the front wheel of the vehicle, serving as the outer panel on the side of the vehicle, used to prevent sand, mud, etc. rolled up by the wheels from splashing onto the bottom of the car during driving. At the same time, the front fender is generally designed according to aerodynamics to reduce the vehicle's driving resistance. In addition, there is generally a certain gap on the back of the front fender to prevent water and mud accumulation and to facilitate maintenance.

[0047] When parking parallel, the driver mainly observes the surrounding environment through the rearview mirror and side mirrors. After confirming that there are no pedestrians or other obstacles, the driver parks the vehicle at the edge of the road based on experience. During the parking process, since the vehicle is generally parked on the right side of the road and the driver's seat is on the left, many drivers find it difficult to judge whether the parking position is appropriate. They also need to get off the vehicle to confirm whether the vehicle is parked in place and adjust the vehicle position to avoid affecting the passage of other vehicles.

[0048] Parallel parking is not only difficult but also prone to vehicle damage. Specifically, due to limited vision, drivers often cannot accurately judge the distance between the front wheels and the curb during parallel parking, causing scrapes and unnecessary damage to the vehicle. Furthermore, blind spots in the front and side of the vehicle increase safety risks for drivers during starting.

[0049] In order to avoid the above-mentioned problems, an embodiment of the present application provides a driving assistance device and a vehicle. The driving assistance device is installed on the front fender and integrates components such as a detection component and a drive component. During parking, the detection component can monitor the distance between the front wheel and obstacles such as curbs and vehicles in front in real time, and retract the detection component into the first installation cavity when the vehicle speed is high to reduce wind resistance and protect the detection component, thereby solving the problems of limited driver vision and difficulty in parallel parking in the prior art.

[0050] It can be understood that the driving assistance device in the embodiment of the present application can be applied to a variety of common vehicles as long as there is a blind spot on the side, including but not limited to passenger cars, commercial vehicles, public transportation, and special-purpose vehicles.

[0051] The following describes in detail the driving assistance device and vehicle provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0052] See Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a driving assistance device, primarily for use on vehicles with blind spots during parallel parking. Such vehicles include front wheels and a front fender 10. The driving assistance device in this embodiment is mounted on the front fender 10 to assist the driver in parallel parking and improve starting safety. The driving assistance device in this embodiment includes a device body 100, a detection assembly 200, and a drive assembly 300.

[0053] The device body 100 is used to be connected to the front fender 10, and a first installation cavity 121 is provided on the device body 100, and the first installation cavity 121 has an inlet and outlet 122; the detection component 200 is at least partially located in the first installation cavity 121, and the detection component 200 is used to obtain distance information between an obstacle on the side of the vehicle or an obstacle in front of the side and the vehicle; the driving component 300 is connected to the detection component 200, and the driving component 300 is used to drive the detection component 200 to move, so that the detection component 200 partially passes through the inlet and outlet 122 and extends outside the first installation cavity 121 to obtain distance information, or the detection component 200 is completely entered into the first installation cavity 121 and stops obtaining distance information.

[0054] Specifically, the detection assembly 200 can be rotatably connected or slidably connected to the first installation cavity 121.

[0055] Illustratively, when the detection assembly 200 is slidably connected to the first installation cavity 121 , the driving assembly 300 is used to drive the detection assembly 200 to move back and forth in the X direction, so that the detection assembly 200 enters and exits the first installation cavity 121 through the inlet and outlet 122 .

[0056] At this time, the driving component 300 can be set as a telescopic electric cylinder, a pneumatic cylinder, a hydraulic cylinder, a gear rack and a motor, etc., as long as it can smoothly drive the detection component 200 to move back and forth relative to the first installation cavity 121.

[0057] Illustratively, when the detection component 200 is rotationally connected to the first installation cavity 121 , the driving component 300 is used to drive the detection component 200 to rotate so that its detection end can extend out of the first installation cavity 121 through the inlet and outlet 122 to obtain distance information.

[0058] At this time, the driving component 300 can be a structure such as a motor or a crank connecting rod that can drive the detection component 200 to rotate, and this embodiment does not limit it here.

[0059] Specifically, the detection component 200 may include a mounting body 230 and a sensor arranged on the mounting body 230. The mounting body 230 is connected to the driving component 300, so that when the mounting body 230 is driven to rotate by the driving component 300, the sensor can extend or retract into the first mounting cavity 121.

[0060] Exemplarily, the sensor can be a camera 220 or a radar 210, or a combination of the camera 220 and the radar 210. The camera 220 is used to obtain image information so that the driver can accurately determine the vehicle position through the image, while the radar 210 can directly measure the distance and broadcast the distance between the vehicle and the obstacle to the driver. It can also issue an alarm when the distance between the vehicle and the obstacle is less than a preset threshold to avoid collision between the front wheels, front fenders 10 and other components and the obstacle.

[0061] Among them, when the sensor includes a camera 220, the detection component 200 can also be linked with the side lights of the vehicle. For example, at night, when the vehicle is parked sideways near the curb, the side lights are started to assist the camera 220 in obtaining image information to improve the safety of side parking.

[0062] The types of sensors used in the above-mentioned detection component 200 are only examples and are not limiting. Other sensors that can assist the driver in determining the vehicle position can be used.

[0063] The distance information in this embodiment may be image information or actual distance information, etc. As long as it can assist the driver in determining the vehicle position and reduce the difficulty of parallel parking, this embodiment does not limit it.

[0064] In addition, the device body 100 can be adaptively designed according to the shape of the front fender 10 so that the device body 100 also has a streamlined shape to reduce resistance and is also more beautiful.

[0065] When performing parallel parking, the detection component 200 is driven to move by the driving component 300 until the detection component 200 partially extends outside the first mounting cavity 121 and reaches the detection position. At this time, the detection component 200 can obtain the distance information between the obstacle on the side of the vehicle or the side in front of the vehicle and the vehicle, and feedback the distance information to the driver. The feedback method can be presented in the form of graphics, or voice prompts, or a combination of the two, thereby assisting the driver to more accurately determine the vehicle position based on the distance information. That is, when parking sideways, the detection component 200 can obtain the distance information between the obstacle on the side of the vehicle and the vehicle, thereby reducing the difficulty of parallel parking and avoiding scratches between the front wheels and the side obstacles. When the vehicle starts, due to the blind spot in the front of the vehicle, safety accidents are prone to occur. Therefore, when starting, the distance information between the obstacle in front of the side and the vehicle can also be obtained by the detection component 200 to assist the driver in improving the safety of starting. When the detection component 200 is not needed, the driving component 300 can be used to drive the detection component 200 to be completely retracted into the first installation cavity 121, thereby reducing the probability of damage to the detection component 200 during high-speed movement or parking of the vehicle. In addition, during high-speed movement of the vehicle, the detection component 200 does not protrude outside the first installation cavity 121, which also helps to reduce wind resistance.

[0066] In some embodiments, a separate controller and battery module can be set up so that the detection component 200 and the driving component 300 are both connected to the controller and the battery module. The controller feeds back distance information and drives the detection component 200 and the driving component 300 to operate, while the battery provides power for the detection component 200 and the driving component 300.

[0067] In some embodiments, see Figure 4 As shown, the detection component 200 and the drive component 300 can be connected to the vehicle's power supply system through the power cable 20, and the detection component 200 and the drive component 300 can be connected to the vehicle's control system through the control cable 30. The power cable 20 is used to transmit electrical energy to provide energy for the detection component 200 and the drive component 300, and the control cable 30 transmits information between the control system and the detection component 200 and the drive component 300 to feedback distance information through the vehicle-mounted control system, and facilitate the driver to directly control the actions of the drive component 300 and the detection component 200 through the vehicle-mounted control system, thereby reducing the number of required components and improving ease of use.

[0068] In some embodiments, a protective plate 400 is provided on the device body 100, and the protective plate 400 is configured to open the inlet and outlet 122 when the detection component 200 needs to partially extend to the outside of the inlet and outlet 122, and to close the inlet and outlet 122 when the detection component 200 completely enters the first installation cavity 121.

[0069] Exemplarily, the protective plate 400 can be connected to the mounting body 230 of the detection component 200, thereby moving synchronously with the detection component 200. When the detection component 200 needs to obtain distance information, the inlet and outlet 122 is automatically opened as the detection component 200 moves. When the detection component 200 retracts into the first mounting cavity 121, the inlet and outlet 122 is automatically closed as the detection component 200 moves back, thereby providing better protection for the detection component 200 when the vehicle is parked or moving at high speed.

[0070] For example, the protection plate 400 may be equipped with an additional driving device to drive the movement so as to open or close the inlet and outlet 122 .

[0071] It can be understood that the above examples are only illustrative of the setting method of the protective plate 400, rather than limiting. As long as the protective plate 400 can open or close the inlet and outlet 122 accordingly as the detection component 200 moves, this embodiment does not limit it.

[0072] In some embodiments, the protective plate 400 is rotatably connected to the cavity wall of the first installation cavity 121 through a reset member 410 .

[0073] The protective plate 400 is configured to push the detection component 200 to open the inlet and outlet 122 when the detection component 200 partially extends to the outside of the inlet and outlet 122, and to close the inlet and outlet 122 under the drive of the reset member 410 when the detection component 200 completely enters the first installation cavity 121.

[0074] Specifically, the reset member 410 may be a common structure such as an automatic device, an electric door closer, a spring hinge, etc., and this embodiment does not limit them.

[0075] The spring hinge has a relatively simple structure and requires no electrical energy. It operates on the torsion of a spring. When the hinge is opened, the torsion spring is stretched or compressed, storing energy. When the spring is released, the stored energy is released, pushing the hinge back to its original position, thereby enabling the protective plate 400 to automatically close the entrance 122, making it more convenient to use. The protective plate 400 is completely driven by the mounting body 230 to open the entrance 122, again requiring no additional energy.

[0076] In some embodiments, two grilles 500 are arranged opposite to each other on the side of the first installation cavity 121 facing away from the front fender 10. The extension direction of the two grilles 500 is the same as the extension direction of the device body 100. The holes on the grilles 500 are connected to the first installation cavity 121. The inlet and outlet 122 are located between the two grilles 500, and the protective plate 400 is rotatably connected to the grilles 500.

[0077] Specifically, when a vehicle is driven or parked in rainy days or in flooded areas, water may enter the first installation cavity 121. Although the protective plate 400 can close the inlet and outlet 122 to protect the detection component 200, when water accumulates in the first installation cavity 121, it is easy to cause the drainage of the accumulated water to be blocked. After adding the grille 500, the holes on the grille 500 can connect the first installation cavity 121 and the outside, so that when water accumulates in the first installation cavity 121, the water can be directly discharged through the grille 500.

[0078] For ease of installation and protection, the driving assembly 300 can be set in the first installation cavity 121. At this time, the driving assembly 300 and the detection assembly 200 installed in the first installation cavity 121 can also be ventilated and cooled through the holes on the grille 500.

[0079] In some embodiments, an arc-shaped air guide plate 600 is also provided on the device body 100. The air guide plate 600 is located between the two grilles 500. One end of the air guide plate 600 is connected to the cavity wall of the first installation cavity 121, and the other end extends to one side of the protective plate 400.

[0080] Specifically, the wind deflector 600 is set to an arc shape according to aerodynamics so that it adapts to the shape of the front fender 10 and has a streamlined shape, which can reduce wind resistance and be more beautiful.

[0081] Furthermore, the protective plate 400 is also configured to be arc-shaped. When the inlet / outlet 122 is closed, the outer surface of the protective plate 400 and the outer surface of the air deflector 600 connect to form an arc-shaped air deflecting surface. That is, when the protective plate 400 closes the inlet / outlet 122, the outer surface of the protective plate 400 and the outer surface of the air deflector 600 form an arc as a whole, creating a streamlined structure that effectively reduces wind resistance.

[0082] In some embodiments, see Figure 1 and Figure 5 As shown, the device body 100 includes a mounting portion 110 and a connecting portion 120. The mounting portion 110 is used to connect to the front fender 10. A second mounting cavity 111 is provided on the mounting portion 110. The connecting portion 120 is located in the second mounting cavity 111 and is connected to the bottom of the second mounting cavity 111 through an adjusting member 123. The first mounting cavity 121 is provided on the connecting portion 120.

[0083] The connecting portion 120 is configured to move toward the second mounting cavity 111 when subjected to an externally applied extrusion force. When the externally applied extrusion force disappears, it is driven by the adjusting member 123 to move until the inlet and outlet 122 is flush with the outer surface of the mounting portion 110 or partially extends to the outside of the second mounting cavity 111.

[0084] Specifically, the mounting portion 110 may include a connecting frame and a main body, the connecting frame being connected to the main body. A second mounting cavity 111 is provided in the main body. The depth of the second mounting cavity 111 is in the opposite direction of the X-direction, and the opening of the second mounting cavity 111 may be flush with the front fender 10, or slightly closer to the outside or inside of the front fender 10. A mounting hole is provided in the front fender 10. The size of the mounting hole may be slightly larger than that of the main body, but must be at least the same as that of the main body. During installation, the main body is inserted into the mounting hole until the connecting frame is secured to the outer surface of the front fender 10. Positioning holes may be provided at the four corners of the connecting frame, and corresponding positioning holes may be provided at corresponding positions on the front fender 10. The connecting frame and the positioning holes on the front fender 10 are locked with bolts. The positioning holes in the connecting frame may be countersunk to prevent the bolts from protruding outside the connecting frame. The shape of the mounting portion 110 can also be adapted to the shape of the front fender 10, both being streamlined to reduce wind resistance.

[0085] The adjusting member 123 may be a spring or damper, for example, that stores energy when compressed and automatically releases the energy to reset itself after the external force is removed. This embodiment is not limited thereto. When the connecting portion 120 is subjected to external pressure, the spring or damper is compressed, causing the connecting portion 120 to move toward the second mounting cavity 111. This reduces the length of the components mounted on the connecting portion 120 that protrude beyond the front fender 10, thereby preventing the protective plate 400 or wind deflector 600 mounted on the connecting portion 120 from rubbing against obstacles on the side of the vehicle, thereby providing improved protection.

[0086] Taking parallel parking as an example, at this time, the protective plate 400 is opened and protrudes to the outside of the front fender 10. If an obstacle contacts the protective plate 400 at this time, the protective plate 400 will be squeezed and an extrusion force will be applied, so that the connecting part 120 and the components installed thereon move as a whole toward the second installation cavity 111 to avoid scratches with obstacles. When leaving the area where the obstacle is located or the obstacle no longer exists, the connecting part 120 will automatically return to its original position and will not affect the normal operation of the detection component 200.

[0087] To better limit the relative position of the connecting portion 120 and the second mounting cavity 111, adjustment members 123 can be provided at the four corners of the connecting portion 120. For example, if the adjustment members 123 are springs, a spring can be provided at each of the four corners of the connecting portion 120, with one end of the spring connected to the connecting portion 120 and the other end connected to the bottom of the second mounting cavity 111. To limit the movement path of the connecting portion 120 and prevent it from deflecting, at least one sliding groove can be provided on the side wall of the second mounting cavity 111, and a slider can be provided on the side wall of the connecting portion 120 so that the slider can move along the slide rail, thereby guiding the movement trajectory of the connecting portion 120.

[0088] In some embodiments, the drive assembly 300 may include a drive motor 310, a driving gear 320 and a driven gear 330 located in the first installation cavity 121. The drive motor 310 can be fixed at the top of the first installation cavity 121. In this way, when there is water accumulated in the first installation cavity 121, it can basically be discharged through the holes on the grille 500. The drive motor 310 is located at the top of the first installation cavity 121, which can reduce the probability of the drive motor 310 coming into contact with the accumulated water.

[0089] Among them, the output shaft of the driving motor 310 is connected to the driving gear 320, the driving gear 320 is meshed with the driven gear 330, and the detection component 200 is eccentrically connected to the eccentric shaft 700, that is, the eccentric shaft 700 is eccentrically set on the installation body 230, and the driven gear 330 is also set on the eccentric shaft 700, which can be key-connected with the eccentric shaft 700, and the eccentric shaft 700 is rotatably connected to the cavity wall of the first installation cavity 121.
