Background
By 2030, all people were provided with a safe, affordable, easy to use, sustainable transportation system, improving road safety, especially expanding public transportation, with special attention to the needs of fragile, women, children, disabled and elderly people. In the automatic driving technique of a vehicle, a vehicle detection device is generally provided inside a bumper (bumper) in front of or behind the vehicle, and a parameter such as a surrounding environment of the vehicle is detected by emitting an electric wave to an outside of the vehicle using a detection means such as a radar (radar) as a basis for automatic driving. However, the radio waves emitted to the outside through the bumper generate different radio wave attenuation amounts at different emission angle portions on the bumper. As described above, the detection member having a wide radio wave emission range (i.e., a wide Field of view) is affected by parameters such as the shape and thickness of the bumper, and the radio wave attenuation amount is varied in different portions. Accordingly, it is desirable to improve the vehicle detection device so as to suppress a difference in radio wave attenuation amount at different locations.

Detailed Description
Fig. 1 is an exploded schematic view of a vehicle detection device according to an embodiment of the present invention, fig. 2 is a schematic top view of the vehicle detection device shown in fig. 1 applied to a vehicle, fig. 3 is a partially enlarged schematic view of a bumper used in the vehicle shown in fig. 1 around an opening, and fig. 4 is a schematic perspective view of a cover member used in the vehicle detection device shown in fig. 1. The following describes specific components of the detecting device 100 for a vehicle according to the present embodiment with reference to fig. 1 to 4, wherein the front and rear directions of the vehicle are, for example, a vehicle front direction Fr and a vehicle rear direction Rr in the drawings, and the left and right directions of the vehicle are, for example, a vehicle left direction L and a vehicle right direction R in the drawings, but these are only one example of the present invention.
Referring to fig. 1 and 2, in the present embodiment, the vehicle detection device 100 is adapted to be mounted around a bumper 52 of a vehicle 50. Among them, the bumper 52 is, for example, a beam structure that is mounted in front of or behind (e.g., disposed on a side corresponding to the vehicle front direction Fr in the drawing) a vehicle body (not shown) of the vehicle 50 and is configured to extend in the vehicle left-right direction (i.e., the vehicle left direction L and the vehicle right direction R in fig. 1), thereby serving as a collision structure on a front side surface or a rear side surface (e.g., disposed on a side corresponding to the vehicle front direction Fr in the drawing) of the vehicle 50. Further, the vehicle detection device 100 is mounted on the periphery of the bumper 52, preferably at positions corresponding to four corners of the vehicle 50 (on both right and left sides of the bumper 52 shown in fig. 1). Thus, the vehicle detection device 100 can be used to detect parameters such as the surrounding environment of the vehicle 50 by emitting radio waves to the outside of the vehicle 50 as a basis for automatic driving. However, the present invention is not limited thereto, and can be adjusted as needed.
Specifically, in the present embodiment, as shown in fig. 1 and 2, the vehicle detection device 100 includes a detection member 110 and a cover member 120. The detection part 110 is installed inside the bumper 52 and corresponds to the opening 52a on the bumper 52. The detection member 110 is, for example, a radar, and is attached to the inside of the bumper 52 such that the detection surface 112 faces the outside, and the detection surface 112 faces the opening 52a. The cover member 120 is provided on the bumper 52 so as to fit the opening 52a. As shown in fig. 3 and 4, an engaging portion 52b is provided around the opening 52a of the bumper 52, an engaged portion 122 is provided at the edge of the cover member 120, and the engaging portion 52b and the engaged portion 122 are engaged with each other. Preferably, the cover member 120 is disposed outside the bumper 52 so as to cover the opening 52a and the detection member 110 corresponding to the opening 52a, but not limited thereto.
In the present embodiment, the outer contour of the cover member 120 corresponds to the inner contour (including the size and shape) of the opening 52a, so that the cover member 120 can be engaged with the engaged portion 122 via the engaging portion 52b, and the cover member 120 can be seamlessly engaged with the opening 52a. In this manner, it can be considered that the portion of the bumper 52 corresponding to the detection member 110 (i.e., the opening 52 a) is replaced by the cover member 120. The cover member 120 is made of a resin material, and thus has a slight material elasticity, and can be slightly deformed by a force, which facilitates the cover member 120 to be more easily engaged with the opening 52a by elastic deformation, and the use of a metal locking member that may interfere with radio waves can be omitted. However, the present invention is not limited to the material of the cover member 120, and it can be adjusted as required.
In addition, in the present embodiment, as shown in fig. 3 and 4, the engaging portion 52b provided at the periphery of the opening 52a of the bumper 52 includes a plurality of engaging protrusions, and the engaged portion 122 provided at the edge of the cover member 120 includes a plurality of engaging holes, and the engaging protrusions and the engaging holes are engaged with each other. Further, a rib 124 protruding in the lateral direction is provided on the edge of the cover member 120, and an engagement hole as the engaged portion 122 is provided on the rib 124. In this way, when the cover member 120 is attached to the opening 52a from the outside of the bumper 52, for example, the laterally projecting rib 124 of the cover member 120 abuts against the side wall projecting from the periphery of the opening 52a, and the plurality of engaging projections as the engaging portions 52b are inserted into the plurality of engaging holes as the engaged portions 122, respectively, contributing to better engagement of the cover member 120 on the opening 52a. However, the present invention is not limited to the number and specific structure of the engaging portions 52b and the engaged portions 122, and the number and the specific structure may be adjusted according to the requirement.
In the present embodiment, as shown in fig. 3 and 4, the edge of the cover member 120 is provided with the positioning portion 126, the periphery of the opening 52a of the bumper 52 is provided with the positioned portion 52c, and the positioning portion 126 and the positioned portion 52c correspond to each other. Preferably, the positioning portion 126 disposed on the edge of the cover member 120 includes a plurality of positioning protrusions, and the positioning portion 52c disposed on the periphery of the opening 52a of the bumper 52 includes a plurality of positioning holes, and the positioning protrusions and the positioning holes are engaged with each other. The positioning projections as the positioning portions 126 are provided to be large in size and located at the corners of the cover member 120, and the engaging holes as the engaged portions 122 are provided to be small in size and distributed over the entire periphery of the edge of the cover member 120. Similarly, the positioning hole as the positioned portion 52c is provided to be large in size and positioned at the corner of the opening 52a of the bumper 52, and the engaging projection as the engaging portion 52b is provided to be small in size and dispersed over the entire periphery of the opening 52a. In this way, when the cover member 120 is attached to the opening 52a from the outside of the bumper 52, for example, the positioning portion 126 and the positioned portion 52c, which are large in size and located at the corners, can be preferentially positioned, and then the engaging portion 52b and the engaged portion 122, which are dispersed over the entire circumference, can be engaged with each other, which helps the cover member 120 to be better engaged with the opening 52a. However, the present invention does not limit the number, specific structure and arrangement of the positioning portions 126 and the positioned portions 52c, and can be adjusted according to the requirement.
Further, in the present embodiment, as shown in fig. 2 and 3, the portion of the bumper 52 corresponding to the detection member 110 (i.e., the opening 52 a) is replaced with the cover member 120, and the thickness of the cover member 120 is adjusted. That is, the thickness of the cover member 120 gradually increases from a position (for example, a center line C shown in fig. 2 and 3) corresponding to the radio wave emission center of the detection member 110 toward the periphery. Here, the position of the cover member 120 corresponding to the radio wave emission center of the detection member 110 (for example, the center line C) corresponds to the position where the radio wave emitted from the detection member 110 passes through the cover member 120 at an emission angle of 0 degrees, and the emission angle increases toward the periphery, so that the thickness of the cover member 120 gradually increases. Preferably, the outer side surface of the cover member 120 corresponds to the outer surface of the bumper 52, so that the thickness of the cover member 120 is increased toward the inner side, thereby maintaining the integrity of the outer shape of the outer surface, but not limited thereto.
In the present embodiment, as shown in fig. 2, the coverage area of the cover member 120 (i.e., the size of the opening 52 a) substantially corresponds to the radio wave emission range RN of the detection member 110, which is approximately a range in which the emission angle is about 80 degrees to the left and right of the radio wave emission center (e.g., the center line C), but this angle value is merely an example of the radio wave emission range RN, and the present invention is not limited thereto. The thickness of the cover member 120 in the direction in which the radio wave passes corresponds to N times the half wavelength of the radio wave, where N is a natural number other than 0, i.e., 1, 2, 3, 4, 5, etc., but is not limited thereto. In this way, the portion of the bumper 52 corresponding to the detection member 110 (i.e., the opening 52 a) is replaced with the cover member 120, and the thickness of the cover member 120 is adjusted in accordance with the emission angle of the radio wave emission range (i.e., the viewing angle) of the detection member 110, thereby preventing the radio wave attenuation amount from generating a drop in level at different portions. Accordingly, the vehicle detection device 100 can suppress a difference in radio wave attenuation amount at different locations.
As described above, in the vehicle detection device of the present invention, the detection member is provided inside the bumper, and the cover member is provided on the bumper so as to fit the opening, corresponding to the opening in the bumper. The periphery of the opening of the bumper is provided with an engaging part, the edge of the cover part is provided with an engaged part, the engaging part and the engaged part are mutually buckled, and the thickness of the cover part is gradually increased from a position corresponding to the radio wave emission center of the detection part to the periphery. Preferably, the thickness of the cover member in the direction in which the radio wave passes corresponds to N times the half wavelength of the radio wave, where N is a natural number other than 0. In this way, the portion of the bumper corresponding to the detection member is replaced with the cover member, and the thickness of the cover member is adjusted in accordance with the emission angle of the radio wave emission range (i.e., the viewing angle) of the detection member, thereby preventing the radio wave attenuation amount from falling at different portions. Accordingly, the vehicle detection device of the present invention can suppress the drop in the radio wave attenuation at different positions.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the embodiments of the present invention, and the essence of the corresponding technical solutions is not disclosed.
