AI Technical Summary
When the existing vehicle detection structure uses autonomous driving technology, it is easy to have random reflections, resulting in identification errors, and it is difficult to change the configuration position of the detection component to avoid random reflections while suppressing costs. Moreover, it is difficult to deform the bumper beam to absorb collision energy when the vehicle collides, which has safety concerns.
Design a vehicle inspection structure, including bumper beam, detection component and filler component. The filling component is installed on the side end of the bumper beam, and covers the opening through structures such as the outer peripheral edge and protrusion and abuts against the inner wall surface of the side end to block the electric waves to reduce the phenomenon of random reflection. At the same time, the non-uniform width design of the protrusion makes it easy to squeeze and destroy during collision, allowing the bumper beam to deform and absorb collision energy.
It effectively reduces identification errors caused by random reflection, improves safety, and takes into account collision deformation performance, ensuring the safety and reliability of the vehicle in autonomous driving and collision situations.

Technical Field
[0001] The utility model relates to a detection structure for a vehicle. Background Art
[0002] In recent years, efforts have been actively made to provide access to sustainable transportation systems that also take into account the disadvantaged positions of traffic participants such as the elderly, the disabled, and children. In order to achieve the above-mentioned goals, research and development efforts are being made to further improve the safety and convenience of traffic through developments related to improving safety. However, in the developments related to improving safety, the vehicle detection structure used in the vehicle's autonomous driving technology is a problem.
[0003] In the prior art, the vehicle detection structure can be set on the inside of the bumper at the front or rear of the vehicle, and it uses detection components such as radar to send radio waves to the outside of the vehicle, thereby detecting parameters such as the surrounding environment of the vehicle as the basis for automatic driving. Strong reflective components such as bumper beams are provided on the inside of the bumper. The radio waves emitted by the detection components enter the hole structure of these strong reflective components after being reflected by the bumper beam, and return to the detection components after generating random reflections in the hole structure, thereby causing recognition errors. In addition, due to the limited layout space of the vehicle, it is difficult to change the configuration position of the detection component to avoid random reflections while suppressing costs. At present, it is also considered to place filling components that are difficult for radio waves to pass through in strong reflective components such as bumper beams to fill the hole structure. However, such an approach makes it difficult for the bumper beam to deform to absorb the collision energy when the vehicle collides, which raises safety concerns.
[0004] The utility model aims to improve safety in order to solve the above-mentioned problems and further improve traffic safety and contribute to the development of a sustainable transportation system. Utility Model Content
[0005] The utility model provides a vehicle detection structure, which can reduce the recognition error caused by the phenomenon of random reflection to improve safety, and can also take into account the collision deformation performance.
[0006] The vehicle detection structure of the utility model comprises: a bumper beam, which is installed on the vehicle to hold the bumper of the vehicle and has a side end and an opening opened at the side end; a detection component, which is installed on the inner side of the vehicle and is located near the side end of the bumper beam; and a filling component, which is installed on the side end of the bumper beam to fill the opening, wherein the filling component comprises an outer peripheral edge portion abutting against the outer peripheral edge of the side end, and a protrusion extending from the opening into the interior of the bumper beam, at least a portion of the protrusion abuts against the inner wall surface of the side end, and in a top view, at least a portion of the protrusion from the front end to the rear end in the vehicle front-rear direction has a different width in the vehicle left-right direction.
[0007] In an embodiment of the present invention, in a top view, the width of the front end portion of the protrusion in the left-right direction of the vehicle is smaller than the width of the rear end portion in the left-right direction of the vehicle.
[0008] In an embodiment of the present invention, in a top view, the width of the middle portion of the protrusion between the front end and the rear end in the left-right direction of the vehicle is greater than the width of other portions of the protrusion in the left-right direction of the vehicle.
[0009] In an embodiment of the present invention, the inner side of the protruding portion has an inclined surface inclined along the front-rear direction of the vehicle.
[0010] In an embodiment of the present invention, the inner side of the protruding portion has a step portion arranged between the front end portion and the rear end portion.
[0011] In an embodiment of the present invention, in a plan view, the lengths of edges of the protruding portion at opposite end sides in the left-right direction of the vehicle are different.
[0012] In an embodiment of the present invention, the filling component further includes a recessed portion provided at an outer portion opposite to the protruding portion, and a shape of the recessed portion corresponds to a shape of the protruding portion, so that the filling component is constituted as a cover structure extending into the inner side of the opening.
[0013] Based on the above, in the vehicle detection structure of the utility model, the filling component is installed on the side end portion of the bumper beam with an opening, and the opening is covered by structures such as the outer peripheral edge portion and the protrusion and abuts against the inner wall surface of the side end portion to fill the opening, which can block radio waves to reduce the phenomenon of random reflection of the vehicle detection structure, thereby improving safety. In addition, the width of at least a part of the protrusion from the front end to the rear end is different (that is, non-uniform width). In this way, the protrusion of the filling component can be easily squeezed and destroyed when facing a collision from the front (the front of the vehicle), so that the bumper beam can be easily deformed to absorb the collision energy. Accordingly, the vehicle detection structure of the utility model can reduce the recognition error caused by the phenomenon of random reflection to improve safety, and can also take into account the collision deformation performance.

[0058] Please refer to Figures 1 to 2C In the first embodiment, the vehicle detection structure 100 is suitable for being installed on the inner side of the bumper 52 of the vehicle 50. The bumper 52 is installed on the front or rear side of the vehicle body 54 of the vehicle 50 in the vehicle front-rear direction ( Figure 1 The detection structure 100 for a vehicle includes a bumper beam 110, a detection component 120, and a filler component 130 (in the left and right directions of the vehicle). The bumper beam 110 is installed on the side corresponding to the front direction Fr, and is configured as a beam structure extending in the left-right direction of the vehicle, thereby serving as a collision structure on the front end side or the rear end side of the vehicle 50. Although a straight bumper 52 is shown as an example here, it can also be set in an arc shape to match the shape of the vehicle 50 (not limited to this). FIG. 2A to FIG. 2C ). The bumper beam 110 is mounted on the vehicle 50 to hold the bumper 52 of the vehicle 50 (as shown in FIG. Figure 1 ), and having a side end portion 112, and an opening 114 opened at the side end portion 112 (as shown Figure 1 and Figure 2C The detection component 120 is installed in the inner part of the vehicle 50 and is located near the side end 112 of the bumper beam 110 (as shown in FIG. Figure 1 The filling member 130 is installed on the side end portion 112 of the bumper beam 110 to fill the opening 114 (as shown). Figure 2C shown).
[0059] Specifically, in this embodiment, if Figure 1 As shown in FIG. 1 , the bumper beam 110 is, for example, installed in front of the vehicle body 54 of the vehicle 50 (on one side corresponding to the front direction Fr), and is configured as a beam structure extending in the left-right direction of the vehicle, thereby holding the bumper 52 in front of the vehicle body 54 along the left-right direction of the vehicle. That is, the bumper beam 110 is provided on the inner side (rear side) of the bumper 52 to connect the bumper 52 to the vehicle body 54. In addition, the bumper beam 110 may be provided as a pair of left and right beam structures (such as a pair of left and right beam structures) that are separated in the left-right direction of the vehicle and located in front of the vehicle body 54. Figure 1The bumper beam 110 may be arranged as a single beam structure (not shown) that spans the vehicle body 54 along the left-right direction of the vehicle. In other embodiments not shown, the bumper beam 110 may also be installed at the rear of the vehicle body 54 of the vehicle 50 (corresponding to the side in the rear direction Rr) to keep the bumper 52 at the rear of the vehicle body 54. This embodiment does not limit the area where the vehicle detection structure 100 is applied to the front or rear of the vehicle 50, and it can be adjusted according to needs.
[0060] Furthermore, in this embodiment, if Figure 1 As shown, a detection component 120 (eg, a radar) is installed near the bumper beam 110 . Figure 1 As an example, a pair of left and right detection components 120 are shown to be provided at the left and right corners of the front of the vehicle body 54 (corresponding to the side of the front direction Fr), and the left and right pair of detection components 120 are respectively located near the left and right pair of bumper beams 110. In other embodiments not shown, the detection components 120 may also be provided at the left and right corners of the rear of the vehicle body 54 (corresponding to the side of the rear direction Rr). Preferably, the detection components 120 are provided at positions corresponding to the four corners of the vehicle 50 (not shown) and are respectively located near the side ends 112 of the bumper beams 110 provided at the front and rear of the vehicle. Thus, the vehicle detection structure 100 can emit radio waves to the outside of the vehicle 50 via the detection component 120 to detect parameters such as the surrounding environment of the vehicle 50 as a basis for automatic driving. However, as long as the vehicle 50 is equipped with the vehicle detection structure 100 (including at least one bumper beam 110 and at least one detection component 120), the present embodiment does not limit the number of bumper beams 110 and detection components 120 and the side of the vehicle 50 to which the detection components 120 are applied, which can be adjusted according to needs. In the case where multiple detection components 120 are provided, it is not limited that all detection components 120 are located near the bumper beam 110, and in the case where multiple bumper beams 110 are provided, it is not limited that detection components 120 are provided near all bumper beams 110.
[0061] In addition, in this embodiment, since the bumper beam 110 has an open opening 114 (such as Figure 2C As shown in the figure, the bumper beam 110 and other strong reflective components may produce random reflections due to the radio waves emitted by the detection component 120, thereby causing recognition errors. In response to this, the filling component 130 is installed on the side end 112 of the bumper beam 110 to fill the opening 114. Figure 2COnly the filling component 130 is shown to be installed on the side end portion 112 of the bumper beam 110 corresponding to the left direction L to fill the opening 114, but in the case where the side ends 112 on both sides of the bumper beam 110 have openings 114 open to the outside (not shown), the filling components 130 can also be installed on the side ends 112 on both sides of the bumper beam 110 to fill the openings 114 on both sides. Preferably, the filling component 130 is installed on the side end portion 112 of the bumper beam 110 and is located between the opening 114 of the bumper beam 110 and the detection component 120, so as to prevent the radio waves of the detection component 120 from being transmitted from the opening 114 to the inside of the strong reflection component such as the bumper beam 110, thereby reducing the phenomenon of random reflection of the vehicle detection structure 100. That is, when a plurality of bumper beams 110 and a plurality of detection members 120 are provided, it is preferred that the filling member 130 be provided at the side end portion 112 of the bumper beam 110 close to the detection member 120 , but the present invention is not limited thereto.
[0062] Furthermore, in this embodiment, if FIG. 2A to FIG. 2C As shown, the filling member 130 includes an outer peripheral edge portion 132 and a protrusion 134. The outer peripheral edge portion 132 abuts against the outer peripheral edge 112a of the side end portion 112, the protrusion 134 extends from the opening 114 into the interior of the bumper beam 110, and at least a portion of the protrusion 134 (for example, the front side surface 134S1 and the rear side surface 134S2 of the protrusion 134 in the vehicle front-to-rear direction, and any one of the upper side surface 134S3 and the lower side surface 134S4 in the vehicle up-down direction) abuts against the inner wall surface 112b of the side end portion 112 (for example, the protrusion 134 has a front side surface 134S1 and a rear side surface 134S2 in the vehicle front-to-rear direction, and a top side surface 134S3 and a bottom side surface 134S4 in the vehicle up-down direction) Figure 2C That is, the plugging member 130 extends into the opening 114 with the protrusion 134 and abuts against the inner wall surface 112b of the side end 112 with at least a portion of the protrusion 134, and the outer peripheral edge 132 abuts against the outer peripheral edge 112a of the side end 112 to cover the gap between the opening 114 and the protrusion 134 (as shown in FIG. Figure 2C As shown), it is installed on the side end 112 to fill the opening 114. And, in the top view (i.e. Figure 2B In the perspective of FIG. 1 , at least a portion of the protrusion 134 from the front end 134P1 to the rear end 134P2 in the vehicle front-rear direction has a different width in the vehicle left-right direction. In other words, the protrusion 134 has a non-uniform width structure along the vehicle front-rear direction.
[0063] As an example, in this embodiment, if FIG. 2A to FIG. 2C As shown, in the top-down perspective (i.e. Figure 2BThe width W1 of the front end portion 134P1 of the protrusion 134 in the left-right direction of the vehicle is smaller than the width W2 of the rear end portion 134P2 in the left-right direction of the vehicle. In addition, the inner side of the protrusion 134 (the side corresponding to the right direction R in this case) has an inclined surface 134V inclined along the front-rear direction of the vehicle. That is, the front end portion 134P1 and the rear end portion 134P2 of different widths are connected by the inclined surface 134V. In this way, in a top view (i.e. Figure 2B (under the perspective of the vehicle), the lengths of the edges of the protrusion 134 at the opposite ends in the left-right direction of the vehicle are different. For example, the edge length L1 of the edge 134L of the protrusion 134 adjacent to the left end of the outer peripheral edge portion 132 is smaller than the edge length L2 of the edge 134R on the right end of the inclined surface 134V. Preferably, the upper side surface 134S3 and the lower side surface 134S4 of the protrusion 134 are formed into planes parallel to each other, and are arranged so that the width gradually increases from the front end 134P1 to the rear end 134P2 to form a shape (here, a trapezoid) with inclined edges so that the edge lengths of the left and right ends are different. In addition, the front side surface 134S1, the rear side surface 134S2, and the inclined surface 134V of the protrusion 134 are formed into planes that are perpendicular to the upper side surface 134S3 and the lower side surface 134S4 and connected to each other. However, the above-mentioned surfaces of the protrusion 134 are not limited to being planes, and are not limited to being parallel or perpendicular to each other.
[0064] Through the above arrangement, in the vehicle detection structure 100 of the present embodiment, the filling component 130 is installed on the side end portion 112 of the bumper beam 110 having the opening 114, and the opening 114 is covered by the outer peripheral edge portion 132 and the protrusion 134 and the inner wall surface 112b of the side end portion 112 is abutted to fill the opening 114, which can block radio waves to reduce the phenomenon of random reflection of the vehicle detection structure 100, thereby improving safety. In addition, the width of at least a portion of the protrusion 134 from the front end portion 134P1 to the rear end portion 134P2 is different (that is, non-uniform width) to form an inclined surface 134V, which helps to reduce the collision load F (such as the collision load F) borne by the vehicle 50 when it is subjected to a frontal collision. Figure 2C The protrusion 134 of the filling component 130 is easily crushed and destroyed when facing a collision from the front (in front of the vehicle), so that the bumper beam 110 can be easily deformed to absorb the collision energy. Accordingly, the vehicle detection structure 100 can reduce the recognition errors caused by the phenomenon of random reflection to improve safety, and can take into account the collision deformation performance. However, the utility model does not limit the specific composition of the vehicle detection structure 100, and does not limit the specific structure of the filling component 130 used in the vehicle detection structure 100, which can be adjusted according to needs.
[0065] Furthermore, in the present embodiment, the filling component 130 is installed on the side end portion 112 of the bumper beam 110 to fill the opening 114 to achieve the purpose of blocking radio waves, so it is preferred that the filling component 130 is formed of a material that shields radio waves. The shielding of radio waves includes reflecting radio waves, absorbing radio waves, etc., which can further block radio waves near the side end portion 112, thereby reducing the recognition error caused by the phenomenon of random reflection of the vehicle detection structure 100. As a material for shielding radio waves, a metal plate can be used to form the filling component 130. As a material for absorbing radio waves, a radio wave absorbing resin can be used. Considering that it is preferred to install the filling component 130 on the side end portion 112 of the bumper beam 110 to fill the opening 114, it is preferred that the filling component 130 is formed of a radio wave absorbing resin. In this way, the filling component 130 can not only effectively absorb radio waves to block radio waves near the side end 112, but also utilize the compressibility of the resin material to tightly contact the inner wall surface 112b of the side end 112 when filling the opening 114. However, the present invention does not limit the material composition and specific structure of the filling component 130, which can be adjusted according to needs.
[0066] Furthermore, in this embodiment, if Figure 2A As shown, the filling member 130 further includes a recessed portion 136 disposed at an outer portion opposite to the protruding portion 134, and the shape of the recessed portion 136 corresponds to the shape of the protruding portion 134, so that the filling member 130 is configured to extend into the inner side of the opening 114 (such as Figure 2C The invention further comprises a cover structure (shown in the figure). That is, through the cooperation between the protrusion 134 and the recessed portion 136, the filling component 130 is constituted as a hollow cover structure with a relatively thin thickness and composed of a plurality of side walls. In this way, the filling component 130 can not only be installed on the side end portion 112 to fill the opening 114, but also reduce the volume, thereby reducing the manufacturing cost. Moreover, setting the filling component 130 as a hollow cover structure helps to make the protrusion 134 of the filling component 130 easily squeezed and destroyed when facing a collision from the front (the front of the vehicle), so that the bumper beam 110 can be easily deformed to absorb the collision energy. However, in other embodiments not shown, the filling component 130 may also not be provided with the recessed portion 136, but constitute a solid block structure. As long as the filling component 130 can be installed on the side end portion 112 of the bumper beam 110 to fill the opening 114, the utility model is not limited thereto.
[0067] Correspondingly, in Figure 3 In the modified example shown, the filling member 130A has a similar structure to the aforementioned filling member 130 (particularly, the protrusion 134A has a similar structure in a top view). Figure 2CThe main difference is that the plugging member 130A has a dividing groove 138 located on the protrusion 134A and dividing the protrusion 134A into two parts. In this way, the plugging member 130A can not only be installed on the side end 112 and fill the opening 114 (for example, Figure 3 Replacement of the packing component 130A Figure 2C In the case where the filling component 130A is provided with a separation groove 138 to divide the protrusion 134A into two parts, the filling component 130A may also be provided with a plurality of recessed portions 136. However, in other embodiments not shown, the separation groove 138 may not be provided on the protrusion 134A, and the protrusion 134A may be provided in a manner avoiding the separation plate (i.e., adjusting the extension range of the protrusion 134A). In the case where the separation groove 138 is provided, the recessed portion 136 may not be provided, and the filling component 130A may constitute two solid block structures (not shown). As long as the filling component 130A can be installed on the side end portion 112 of the bumper beam 110 to fill the opening 114, the present invention is not limited thereto.
[0068] Please refer to FIG. 4A to FIG. 4C In the second embodiment, the vehicle detection structure 100B is suitable for being installed on the inner side of the bumper 52 of the vehicle 50 (for example, the vehicle detection structure 100B is replaced by Figure 1 The vehicle detection structure 100B includes a bumper beam 110, a detection member 120, and a filling member 130B (in FIG. 4A to FIG. 4C ), the filling member 130B is installed on the side end portion 112 of the bumper beam 110 to fill the opening 114 (as shown in Figure 4C That is, the main difference between the vehicle detection structure 100B and the aforementioned vehicle detection structure 100 is that the structure of the filling component 130B is different from the aforementioned filling component 130. The rest of the parts can refer to the aforementioned description and will not be elaborated here.
[0069] Specifically, in this embodiment, if FIG. 4A to FIG. 4CAs shown, the filling member 130B includes an outer peripheral edge portion 132 and a protrusion 134B. The outer peripheral edge portion 132 abuts against the outer peripheral edge 112a of the side end portion 112, the protrusion 134B extends from the opening 114 into the interior of the bumper beam 110, and at least a portion of the protrusion 134B (for example, the front side surface 134S1 and the rear side surface 134S2 of the protrusion 134B in the vehicle front-to-rear direction, and any one of the upper side surface 134S3 and the lower side surface 134S4 in the vehicle up-down direction) abuts against the inner wall surface 112b of the side end portion 112 (for example, the protrusion 134B has a front side surface 134S1 and a rear side surface 134S2 in the vehicle front-to-rear direction, and an upper side surface 134S3 and a lower side surface 134S4 in the vehicle up-down direction) Figure 4C That is, the plugging member 130B extends into the opening 114 with the protrusion 134B and abuts against the inner wall surface 112b of the side end 112 with at least a portion of the protrusion 134B, and the outer peripheral edge 132 abuts against the outer peripheral edge 112a of the side end 112 to cover the gap between the opening 114 and the protrusion 134B (as shown in FIG. Figure 4C As shown), it is installed on the side end 112 to fill the opening 114. And, in the top view (i.e. Figure 4B In other words, the protrusion 134B has a non-uniform width structure along the vehicle front-rear direction.
[0070] As an example, in this embodiment, if FIG. 4A to FIG. 4C As shown, in the top-down perspective (i.e. Figure 4B), the width W3 of the front end portion 134P1 of the protrusion 134B in the left-right direction of the vehicle is smaller than the width W4 of the rear end portion 134P2 in the left-right direction of the vehicle. Furthermore, the inner side of the protrusion 134B (here, the side corresponding to the right direction R) has a step portion 134T provided between the front end portion 134P1 and the rear end portion 134P2. That is, the front end portion 134P1 and the rear end portion 134P2 having different widths are connected by the step portion 134T. In this way, in a top view, the edge lengths of the opposite end sides of the protrusion 134B in the left-right direction of the vehicle are different. For example, the edge length L3 of the edge 134L of the protrusion 134B adjacent to the left end side of the outer peripheral edge portion 132 is smaller than the edge length L4 of the edge 134R on the right end side constituting the step portion 134T. Preferably, the upper side surface 134S3 and the lower side surface 134S4 of the protrusion 134B are formed into planes parallel to each other, and are configured such that the width of the front end portion 134P1 is larger than the width of the rear end portion 134P2 and has a bent edge so that the lengths of the edges on the left and right ends are different (here, a stepped shape). In addition, the three surfaces of the front side surface 134S1, the rear side surface 134S2, and the step portion 134T of the protrusion 134B are formed into planes that are perpendicular to the upper side surface 134S3 and the lower side surface 134S4 and connected to each other. However, the above-mentioned surfaces of the protrusion 134B are not limited to being planes, and are not limited to being parallel or perpendicular to each other.
[0071] Through the above arrangement, in the vehicle detection structure 100B of the present embodiment, the filling component 130B is installed on the side end portion 112 of the bumper beam 110 having the opening 114, and the opening 114 is covered by the outer peripheral edge portion 132 and the protrusion 134B and the inner wall surface 112b of the side end portion 112 is abutted to fill the opening 114, which can block radio waves to reduce the phenomenon of random reflection of the vehicle detection structure 100B, thereby improving safety. In addition, the width of at least a portion of the protrusion 134B from the front end portion 134P1 to the rear end portion 134P2 is different (that is, non-uniform width) to form a step portion 134T, which helps to reduce the collision load F (such as the collision load F) borne by the vehicle 50 when it is subjected to a frontal collision. Figure 4C The filler member 130B is transmitted from the front end portion 134P1 to the rear end portion 134P2 (as shown by the arrow), so that the protrusion 134B of the filler member 130B can be easily squeezed and destroyed when facing a collision from the front (in front of the vehicle), so that the bumper beam 110 can be easily deformed to absorb the collision energy. Accordingly, the vehicle detection structure 100B can reduce the recognition errors caused by the phenomenon of random reflection to improve safety, and can take into account the collision deformation performance. However, the utility model does not limit the specific composition of the vehicle detection structure 100B, and does not limit the specific structure of the filler member 130B used in the vehicle detection structure 100B, which can be adjusted according to needs.
[0072] Similarly, in this embodiment, if Figure 4A As shown, the plugging member 130B further includes a recessed portion 136 disposed at an outer portion opposite to the protruding portion 134B, and the shape of the recessed portion 136 corresponds to the shape of the protruding portion 134B, so that the plugging member 130B is configured to extend into the inner side of the opening 114 (such as Figure 4C ) of the cover structure. That is, through the cooperation between the protrusion 134B and the recessed portion 136, the filling component 130B is formed into a hollow cover structure with a relatively thin thickness and composed of a plurality of side walls. In this way, the filling component 130B can not only be installed on the side end portion 112 to fill the opening 114, but also reduce the volume, thereby reducing the manufacturing cost. In addition, setting the filling component 130B as a hollow cover structure helps to make the protrusion 134B of the filling component 130B easily squeezed and destroyed when facing a collision from the front (the front of the vehicle), so that the bumper beam 110 can be easily deformed to absorb the collision energy. Correspondingly, in Figure 5 In the modified example shown, the filling member 130C has a similar structure to the aforementioned filling member 130B (particularly, the protrusion 134C has a similar structure in a top view). Figure 4C The main difference is that the plugging member 130C has a dividing groove 138 located on the protrusion 134C and dividing the protrusion 134C into two parts. In this way, the plugging member 130C can not only be installed on the side end 112 and fill the opening 114 (for example, Figure 5 Replacement of the packing component 130C Figure 4C The filling member 130B can be installed on the side end 112 of the bumper beam 110 to fill the opening 114, and the separation groove 138 can be used to avoid the structure near the opening 114 (for example, the reinforcing plate), so as to increase the stability of the filling member 130C installed on the side end 112. However, the arrangement of the recessed portion 136, the separation groove 138, etc. can be adjusted according to needs. As long as the filling member 130C can be installed on the side end 112 of the bumper beam 110 to fill the opening 114, the utility model is not limited thereto.
[0073] Please refer to FIG. 6A to FIG. 6C In the third embodiment, the vehicle detection structure 100D is suitable for being installed on the inner side of the bumper 52 of the vehicle 50 (for example, the vehicle detection structure 100D is replaced by Figure 1 The vehicle detection structure 100D includes a bumper beam 110, a detection member 120, and a filling member 130D (in FIG. 6A to FIG. 6C ), the filling member 130D is installed on the side end portion 112 of the bumper beam 110 to fill the opening 114 (as shown in Figure 6CThat is, the main difference between the vehicle detection structure 100D and the aforementioned vehicle detection structure 100 and vehicle detection structure 100B is that the structure of the filling component 130D is different from the aforementioned filling component 130 and filling component 130B. The rest of the parts can refer to the aforementioned description and will not be elaborated here.
[0074] Specifically, in this embodiment, if FIG. 6A to FIG. 6C As shown, the filling member 130D includes an outer peripheral edge portion 132 and a protrusion 134D. The outer peripheral edge portion 132 abuts against the outer peripheral edge 112a of the side end portion 112, the protrusion 134D extends from the opening 114 into the interior of the bumper beam 110, and at least a portion of the protrusion 134D (for example, the front side surface 134S1 and the rear side surface 134S2 of the protrusion 134D in the vehicle front-to-rear direction, and any one of the upper side surface 134S3 and the lower side surface 134S4 in the vehicle up-down direction) abuts against the inner wall surface 112b of the side end portion 112 (for example, the protrusion 134D has a front side surface 134S1 and a rear side surface 134S2 in the vehicle front-to-rear direction, and an upper side surface 134S3 and a lower side surface 134S4 in the vehicle up-down direction) Figure 6C That is, the plugging member 130D extends into the opening 114 with the protrusion 134D and abuts against the inner wall surface 112b of the side end 112 with at least a portion of the protrusion 134D, and the outer peripheral edge 132 abuts against the outer peripheral edge 112a of the side end 112 to cover the gap between the opening 114 and the protrusion 134D (as shown in FIG. Figure 6C As shown), it is installed on the side end 112 to fill the opening 114. And, in the top view (i.e. Figure 6B In other words, the protrusion 134D has a non-uniform width structure along the vehicle front-rear direction.
[0075] As an example, in this embodiment, if FIG. 6A to FIG. 6C As shown, in the top-down perspective (i.e. Figure 6B(from a perspective of ), the width W5 of the middle portion 134P3 of the protrusion 134D between the front end portion 134P1 and the rear end portion 134P2 in the left-right direction of the vehicle is greater than the width of the other portions of the protrusion 134D in the left-right direction of the vehicle (for example, greater than the width W6 of the front end portion 134P1 and greater than the width W7 of the rear end portion 134P2). In addition, the inner side of the protrusion 134D (here, the side corresponding to the right direction R) has an inclined surface 134V1 and an inclined surface 134V2 provided between the front end portion 134P1 and the rear end portion 134P2. That is, the front end portion 134P1 and the middle portion 134P3, which have different widths, are connected by the inclined surface 134V1, and the middle portion 134P3 and the rear end portion 134P2, which have different widths, are connected by the inclined surface 134V2. Thus, in a top view, the edge lengths of the opposite ends of the protrusion 134D in the left-right direction of the vehicle are different. For example, the edge length L5 of the edge 134L of the protrusion 134D adjacent to the outer peripheral edge 132 is smaller than the edge length L6 of the edge 134R on the right end of the inclined surface 134V1 and the inclined surface 134V2. Preferably, the upper side surface 134S3 and the lower side surface 134S4 of the protrusion 134D are formed as planes parallel to each other, and are set to have a pair of inclined edges so that the width gradually increases from the front end 134P1 to the middle part 134P3 and gradually decreases from the middle part 134P3 to the rear end 134P2 to form a shape (here, a hexagon) with different edge lengths on the left and right ends. The front side 134S1, rear side 134S2, and inclined surfaces 134V1 and 134V2 of the protrusion 134D are planes perpendicular to the upper side 134S3 and the lower side 134S4 and connected to each other. However, the above-mentioned surfaces of the protrusion 134D are not limited to being planes, and are not limited to being parallel or perpendicular to each other.
[0076] Through the above arrangement, in the vehicle detection structure 100D of the present embodiment, the filling component 130D is installed on the side end portion 112 of the bumper beam 110 having the opening 114, and the opening 114 is covered by the outer peripheral edge portion 132 and the protrusion 134D and the inner wall surface 112b of the side end portion 112 is abutted to fill the opening 114, which can block radio waves to reduce the phenomenon of random reflection of the vehicle detection structure 100D, thereby improving safety. In addition, the width of at least a portion of the protrusion 134D from the front end portion 134P1 to the rear end portion 134P2 is different (that is, non-uniform width) to form inclined surfaces 134V1 and inclined surfaces 134V2, which helps to reduce the collision load F (such as the collision load F) borne by the vehicle 50 when it is subjected to a frontal collision. Figure 6CThe filler member 130D is transmitted from the front end portion 134P1 to the rear end portion 134P2 (as shown by the arrow), so that the protrusion 134D of the filler member 130D can be easily squeezed and destroyed when facing a collision from the front (the front of the vehicle), so that the bumper beam 110 can be easily deformed to absorb the collision energy. Accordingly, the vehicle detection structure 100D can reduce the recognition errors caused by the phenomenon of random reflection to improve safety, and can take into account the collision deformation performance. However, the utility model does not limit the specific composition of the vehicle detection structure 100D, and does not limit the specific structure of the filler member 130D used in the vehicle detection structure 100D, which can be adjusted according to needs.
[0077] Similarly, in this embodiment, if Fig. 6A As shown, the filling member 130D further includes a recessed portion 136 disposed at an outer portion opposite to the protruding portion 134D, and the shape of the recessed portion 136 corresponds to the shape of the protruding portion 134D, so that the filling member 130D is configured to extend into the inner side of the opening 114 (such as Figure 6C ) of the cover structure. That is, through the cooperation between the protrusion 134D and the recessed portion 136, the filling component 130D is formed into a hollow cover structure with a relatively thin thickness and composed of a plurality of side walls. In this way, the filling component 130D can not only be installed on the side end portion 112 to fill the opening 114, but also reduce the volume, thereby reducing the manufacturing cost. In addition, setting the filling component 130D as a hollow cover structure helps to make the protrusion 134D of the filling component 130D easily squeezed and destroyed when facing a collision from the front (the front of the vehicle), so that the bumper beam 110 can be easily deformed to absorb the collision energy. Correspondingly, in Figure 7 In the modified example shown, the filling member 130E has a similar structure to the aforementioned filling member 130D (particularly, the protrusion 134E has a similar structure in a top view). Figure 6C The main difference is that the plugging member 130E has a dividing groove 138 located on the protrusion 134E and dividing the protrusion 134E into two parts. In this way, the plugging member 130E can not only be installed on the side end 112 and fill the opening 114 (for example, Figure 7 Replacement of the packing component 130E Figure 6C The filling component 130E can be installed on the side end portion 112 to fill the opening 114. The separation groove 138 can also avoid the structure near the opening 114 (for example, the reinforcing plate), so as to increase the stability of the filling component 130E installed on the side end portion 112. However, the arrangement of the recessed portion 136, the separation groove 138, etc. can be adjusted according to needs. As long as the filling component 130E can be installed on the side end portion 112 of the bumper beam 110 to fill the opening 114, the utility model is not limited thereto.
[0078] Although the above three embodiments and their variations illustrate the Figure 2C , Figure 4C , Figure 6C The protrusions 134 to 134E have different shapes (from a perspective of the vehicle), but the purpose is to make the width of at least a portion of the protrusions 134 to 134E from the front end 134P1 to the rear end 134P2 in the vehicle front-to-rear direction different (that is, non-uniform width), and preferably have inclined surfaces 134V, 134V1, 134V2 or step portions 134T on the inner sides of the protrusions 134 to 134E, but as long as the filling components 130 to 130E can be installed on the side end 112 of the bumper beam 110 to fill the opening 114, and their protrusions 134 to 134E have non-uniform widths when viewed from a top view. That is, compared with the method of forming a plane between the front end 134P1 and the rear end 134P2 with a uniform width, the method of forming an inclined surface 134V, 134V1, 134V2 or a step portion 134T between the front end 134P1 and the rear end 134P2 with a non-uniform width helps to transfer the collision load F borne by the vehicle 50 when it is subjected to a frontal collision from the front end 134P1 to the rear end 134P2, so that the protrusions 134 to 134E of the filling parts 130 to the filling parts 130E can be easily crushed and broken when facing a collision from the front (the front of the vehicle). Therefore, in other embodiments not shown, the front end 134P1 and the rear end 134P2 may also have a curved surface or a corrugated surface different from the inclined surface 134V, 134V1, 134V2 or the step portion 134T. Furthermore, an embodiment in which the width of the front end portion 134P1 is greater than that of the rear end portion 134P2 is not excluded.
[0079] In summary, in the vehicle detection structure of the utility model, the filling component is installed on the side end portion of the bumper beam with an opening, and the opening is covered by the outer peripheral edge portion and the protrusion and the inner wall surface of the side end portion is abutted to fill the opening, which can block the radio waves to reduce the phenomenon of random reflection of the vehicle detection structure, thereby improving safety. In addition, the width of at least a part of the protrusion from the front end to the rear end is different (that is, non-uniform width). Preferably, in a top view, the width of the front end of the protrusion is smaller than the width of the rear end, or the width of the middle part of the protrusion is greater than the width of other parts, and the inner side of the protrusion has an inclined surface or a step difference portion, so that the length of the edge of the protrusion on the opposite ends of the vehicle in the left and right directions is different. In this way, the protrusion of the filling component can be easily squeezed and destroyed when facing a collision from the front (the front of the vehicle), so that the bumper beam can be easily deformed to absorb the collision energy. Accordingly, the vehicle detection structure of the utility model can reduce the recognition error caused by the phenomenon of random reflection to improve safety, and can take into account the collision deformation performance.
[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solution of the embodiments of the utility model.
