In an embodiment according to the present invention, because the central axis of the adjusting rod 502 overlaps or coincides with the central axis of the lens of the camera module 103, the central axis of the lens of the camera module 103 is also in a horizontal position, so that the angle formed by the central axis of the lens of the camera module 103 and the mounting surface is 90 degrees. The field of view obtained by the lens of the camera module 103 in the initial position can be seen in fig. 7. In the extreme position (shown by the adjustment lever 502 '), the centre axis of the adjustment lever 502' is in a near vertical position. In theory, in the extreme position, the central axis of the adjustment rod 502 'may be in a vertical position, but in practical applications, the central axis of the adjustment rod 502' may only be close to a vertical position and not in a completely vertical position. For example, in the extreme position, an angle formed by the center line of the lens of the camera module 103 and the mounting surface may be 0.5 to 30 degrees, preferably 5 to 25 degrees, more preferably 15 to 20 degrees, and for example 18 degrees. In an embodiment according to the present invention, an angle formed by the central line of the lens of the camera module 103 and the mounting surface is 17.5 degrees. It is noted that the adjusting lever 502 in the initial position and the adjusting lever 502' in the extreme position are shown in fig. 5 at the same time, and such expressions are merely provided for clarity of explanation of the positions of the two end points of the adjusting lever 502, and are not provided for limiting the scope of the embodiment of the adjusting lever 502 in the exemplary configuration.

In addition, as shown in fig. 5, the intelligent driving assistance apparatus 10 further includes a function main board 201 and

connection lines

202 and 203. The LED lamps at the LED lamp holes 112 are communicatively connected to the functional motherboard 201, for example, by a connection line 202. The circuit board of the camera module 103 is in communication connection with the functional motherboard 201, for example, through a connection line 203. Also shown in fig. 5 is a volume up or down button 115.

Fig. 6 schematically shows an enlarged schematic structural view of a lens adjustment device for an intelligent driving assistance apparatus according to the present invention. As described above, the vehicle driving assistance apparatus 10 includes at least the housing, the camera module 103, and the lens angle adjustment device 50. In fig. 6, a specific structure of the lens angle adjusting apparatus 50 can be seen. The lens angle adjusting device 50 includes a first limiting mechanism 501 and a second limiting mechanism 504, wherein the first limiting mechanism 501 is fixedly connected to the housing, the second limiting mechanism 504 is connected to the camera module 103, and an angle of the lens of the camera module 103 relative to the housing can be adjusted by changing a position of the second limiting mechanism 504 relative to the first limiting mechanism 501. In an embodiment according to the present invention, the angle adjusting device 50 includes at least one spring element 507, and the connection or disconnection between the first limiting mechanism 501 and the second limiting mechanism 504 can be realized through at least one spring element 507. In another embodiment according to the present invention, the angle adjusting device comprises an adjusting rod 502, the adjusting rod 502 is fixedly connected to the second limiting mechanism 504, and the first limiting mechanism 501 can be connected to or disconnected from the second limiting mechanism 504 and the second limiting mechanism 504 can be moved relative to the first limiting mechanism 501 by the cooperation of the adjusting rod 502 and the at least one spring element 507. The engagement between the adjustment lever 502 and the at least one spring member 507 enables accurate positioning of the rotational angle of the lens. For example, the first stopper mechanism 501 can be disengaged from the second stopper mechanism 504 by pressing the adjustment lever 502. By pressing and pushing the adjustment lever 502, not only the first position-limiting mechanism 501 can be disengaged from the second position-limiting mechanism 504 but also the second position-limiting mechanism 504 can be moved relative to the first position-limiting mechanism 501, and then, for example, by releasing the adjustment lever 502, the first position-limiting mechanism 501 can be re-engaged or locked with the second position-limiting mechanism 504. In this way, the rotation of the lens can be realized, the adjustment and the installation are simple and flexible, and the precision is high. In an embodiment according to the present invention, the first position-limiting mechanism 501 has a plurality of protruding portions and/or the second position-limiting mechanism 504 has at least one protruding portion. In the exemplary embodiment shown in fig. 6, the first limiting mechanism 501 may be, for example, a rack or a bridge 501, and the rack or bridge 501 may have an arc shape or an arc shape, for example. The rack or bridge 501 has a plurality of serrated raised portions. The second limiting mechanism 504 may be, for example, a limiting pad 504, and at least one convex portion and/or at least one concave portion is disposed on the limiting pad 504.

In an embodiment according to the present invention, the camera module 103 has a camera module swivel base 509, the camera module 103 may be formed integrally with the swivel base 509, for example, the camera module swivel base 509 has a rotation axis 508, and the rotation axis 508 may be rotatably connected to the housing, i.e., may be rotatably connected to the housing. For example, the rotating shaft 508 is rotatably fixed on the fixing seat of the housing, so as to achieve stable positioning of the camera module in the housing. In another embodiment according to the present invention, the camera module rotating base 509 is fixed or rigidly connected to the camera module 103. Furthermore, a plurality of first struts 511 and at least one second strut 512 are arranged on the camera module swivel base 509, wherein the plurality of first struts 511 are used for supporting and/or fixing the camera module 103, in particular for supporting and/or fixing a substrate 513 of the camera module 103. That is, the substrate 513 of the camera module 103 is supported on the camera module rotating base 509 by the plurality of first support columns 511, so that the substrate 513 of the camera module 103 and the substrate of the camera module rotating base 509 are arranged in parallel and in a fixed position relative to each other. At least one guide cylinder 506 is arranged on the limiting plate 504, and the at least one guide cylinder 506 extends from the limiting plate 504 and through the base plate 513 of the camera module 103. The base plate 513 has a guide hole or a guide recess through which the at least one guide drum 506 can be moved back and forth or against which it rests. At least one spring element 507 is fitted over the corresponding second leg 512, wherein one end of the spring element 507 is supported on the base plate of the camera module swivel mount 509 and the other end is supported on the end of the guide cylinder 506 of the position limiting pad 504. Due to the elastic function (flexibility) of the spring member 507, the relative distance between the camera module rotating base 509 and the limit pad 504 can be changed in a telescopic manner, so that the relative distance between the base 513 of the camera module 103 and the limit pad 504 can be changed in a telescopic manner.

As can also be seen in fig. 6, the adjustment lever 502 is located in the sliding groove 503, and the adjustment lever 502 can be moved along the sliding groove 503. The adjustment rod 502 is fixedly or rigidly connected to the limiting pad 504. In an embodiment according to the present invention, the adjusting rod 502 is integrally formed with the limiting pad 504. In an embodiment according to the present invention, the adjusting rod 502 is connected with the limiting pad 504 in a screw fastening manner. The adjusting rod 502 can be, for example, a threaded rod that can be screwed into a threaded hole in the limiting plate 504 to achieve a secure connection of the threaded rod to the limiting plate 504. It is obvious to those skilled in the art that the height of the threaded rod protruding from the surface of the restraining pad 504 and the surface of the sliding groove 503 can be adjusted by controlling the screwing depth of the threaded rod into the threaded hole. In the installation and commissioning process of the intelligent driving assistance device 10, after the angle of the lens of the camera module 103 relative to the housing is adjusted and determined, the position and the angle of the camera module 103 relative to the housing can be further fastened by screwing the threaded rod, so that the stability of the lens in the intelligent driving assistance device 10 is further enhanced.

As shown in fig. 6, the first limiting mechanism 501, such as a rack or a bridge, has a fastening connection portion 510 at an end thereof, and the rack or the bridge can be fixed to the housing by, for example, a screw and the fastening connection portion 510.

As already described above, the camera module swivel base 509 has a swivel axis 508, and the swivel axis 508 can be fixed to the housing of the intelligent driving assistance device 10 in a pivotable manner, so that the camera module 103 can be pivoted relative to the housing of the intelligent driving assistance device 10. In an embodiment according to the present invention, the second limiting mechanism 504 is a limiting pad 504, the limiting pad 504 has a guiding tube 506, a first limiting portion 505 and a second limiting portion 515, wherein the first limiting portion 505 can limit the position of the rack 501 in a first direction X, and the second limiting portion 515 can limit the position of the rack 501 in a second direction Y, wherein the first direction X is the moving direction of the adjusting rod 502, and the second direction Y is perpendicular to the first direction X and the optical axis direction (third direction) Z of the lens. When the adjustment lever 502 moves in the sliding slot 503 of the first limiting mechanism 501, the second limiting portion 515 moves along the outer edge of the first limiting mechanism 501 in a manner of abutting against the first limiting mechanism 501. The adjusting rod 502 and the second limiting portion 515 are both fixedly connected to the limiting base plate 504 or integrally formed. In an alternative according to the present invention, the second limit portion 515 may be replaced by one or more angle indication posts having indication tips pointing to the scale marks on the rack 501, thereby indicating the current lens angle value. The scale marks facilitate accurate angular positioning of the lens. It is obvious to those skilled in the art that, since the adjusting rod 502 is located in the sliding slot 503 of the first limiting mechanism 501 (as shown in fig. 6), the adjusting rod 502 has a limiting effect on the position of the first limiting mechanism 501 in the second direction Y.

Fig. 7 shows a schematic cross-sectional view of an intelligent driving assistance device according to the invention. In the cross-sectional view shown in fig. 7, the upper housing 101, the lower housing 102, the camera module 103, the fixing mechanism 104, the rack 501, the adjusting rods 502 and 502', the limiting base plate 504, and the camera module rotating base 509 are all clearly visible. Furthermore, the upper connection line 107 and the lower connection line 108 are clearly visible in fig. 7. As shown in fig. 7, the adjusting rod 502 is fixedly connected to the limiting pad 504. In an embodiment according to the present invention, the adjusting rod 502 is screwed, bolted or integrally formed with the limiting pad 504. The distance between the limiting pad 504 and the camera module swivel mount 509 can be adjusted by a spring element. By pressing the adjustment lever 502, the first limit portion 505 (e.g., limit teeth) on the limit pad 504 can be disengaged from the teeth of the rack 501, so that the adjustment lever 502 can be further pushed to move in the direction toward the limit position. During the movement, if the pressing of the adjusting lever 502 is stopped, the first limiting portion 505 of the limiting pad 504 can be engaged with the teeth of the rack 501 again, thereby adjusting the angle of the lens from the initial angle to the corresponding angle. In fig. 7, the adjustment lever 502 is shown in solid lines in its initial position. The adjustment lever 502' shown in dashed lines indicates the position and state of the adjustment lever in its extreme position. In the extreme position of the adjustment lever 502 ', other parts or components connected to the adjustment lever 502' are not shown in order not to obscure the drawing and unnecessarily make the structure and the connection of the intelligent driving assistance device difficult to understand. In the initial position of the adjustment rod 502, the central axis of the adjustment rod 502 overlaps or coincides with the central axis of the lens of the camera module 103, that is, both are in the horizontal direction. When the adjustment lever 502 is at its initial position, the optical axis direction Z of the lens, which is the third direction Z in the coordinate system shown in fig. 6 and 7, is perpendicular to the mounting surface of the vehicle driving assistance apparatus 10. In the extreme position of the adjustment lever 502', the lens angle is in the extreme angle of the adjustable lens angle range, wherein the adjustable angle range is about 90 degrees. When the adjusting lever 502 is at its initial position, an angle formed by a center line of a lens of the camera module 103 and the mounting surface may be, for example, 90 degrees. When the adjusting lever 502' is at its extreme position, the angle formed by the center line of the lens of the camera module 103 and the mounting surface may be, for example, 0.5 to 30 degrees, preferably 5 to 25 degrees, more preferably 15 to 20 degrees, for example 18.3 degrees. In an embodiment according to the present invention, an angle formed by the central line of the lens of the camera module 103 and the mounting surface is 16.5 degrees. Note that the adjusting lever 502 in the initial position and the adjusting lever 502' in the extreme position are shown in fig. 7 at the same time, and such representation is only for the purpose of clearly explaining the two end positions of the adjusting lever 502, and is not intended to limit the scope of the implementation of the adjusting lever 502 in the exemplary structure.

It will be apparent to those skilled in the art that numerous modifications and variations can be made to the embodiments described herein without departing from the spirit and scope of the claimed subject matter. Thus, it is intended that the present specification cover the modifications and variations of the various embodiments described herein provided they come within the scope of the appended claims and their equivalents.
