Description

Technical Field

[0001] The technology disclosed herein relates to a front bumper. In particular, the technology disclosed herein relates to a front bumper including an electronic device placed inside the front bumper. Background Art

[0002] Japanese Unexamined Patent Application Publication No. 2004-203158 (JP 2004-203158 A) discloses a front bumper including a bumper body (referred to as a "bumper face" in JP 2004-203158 A) and a bumper inner (referred to as a "reinforcement member" in JP 2004-203158 A). The bumper body is fixed to a vehicle body (e.g., an undercover) via the bumper inner located on the lower portion of the bumper body. Summary of the Invention

[0003] The electronic device may be placed between the bumper body and the inside of the bumper. In this case, the space in which the electronic device exists is smaller than the space in which the electronic device exists in the case where the electronic device is placed between the bumper body and the vehicle body in a configuration in which the bumper body is directly fixed to the vehicle body. A load may be applied externally to the bumper body exposed to the outside of the vehicle. In the configuration in which the electronic device is placed between the bumper body and the inside of the bumper, when a load is applied externally to the bumper body and the bumper body deforms inwardly, the electronic device is compressed between the bumper body and the inside of the bumper and the electronic device may be damaged. The present specification provides a front bumper that can reduce damage to the electronic device when a load is applied to the bumper body from the outside of the vehicle.

[0004] A front bumper disclosed herein includes a bumper body, a bumper interior, and a first electronic device. The bumper body is exposed to the exterior of a vehicle. The bumper interior is located on the inner side of the bumper body and is configured to fix the bumper body to the body of the vehicle. The first electronic device is located between the bumper body and the bumper interior. The bumper interior includes an inner body facing at least a portion of the first electronic device in a first direction, and at least one columnar portion positioned adjacent to the first electronic device in a second direction perpendicular to the first direction and extending from the inner body toward the bumper body in the first direction. In the front bumper disclosed herein, the length of the at least one columnar portion in the first direction is greater than the length of the first electronic device in the first direction. The front bumper is configured to be mounted on the front of a vehicle.

[0005] In the above front bumper, the first electronic device is located between the bumper body and the bumper interior, and the bumper interior faces at least a portion of the first electronic device in a first direction. Therefore, when a load is applied to the bumper body from the outside of the vehicle and the bumper body is displaced in the first direction, the first electronic device may be damaged. However, a columnar portion that is longer than the first electronic device in the first direction is located between the bumper body and the inner body and is adjacent to the first electronic device in a second direction perpendicular to the first direction. Accordingly, even when a load is applied to the bumper body from the outside of the vehicle and the bumper body is displaced in the first direction, the columnar portion can prohibit or reduce the displacement of the bumper body (in particular, the displacement of the bumper body relative to the bumper interior) before the first electronic device is compressed between the bumper body and the bumper interior. As described above, the front bumper disclosed herein can avoid or reduce damage to the first electronic device when a load is applied to the bumper body from the outside of the vehicle.

[0006] Details and further improvements of the technology disclosed herein are described in the following "Detailed Description" section. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Features, advantages, and technical and industrial significance of exemplary embodiments of the present invention will be described below with reference to the accompanying drawings, in which like symbols represent like elements, and in which:

[0008] Figure 1 is a front view of a vehicle 100 equipped with a front bumper 10 according to an embodiment;

[0009] Figure 2 is an exploded perspective view of the front bumper 10 of the embodiment;

[0010] Figure 3 It is along Figure 1 a cross-sectional view taken along line III-III in FIG; and

[0011] Figure 4 It is along Figure 3 A cross-sectional view taken along line IV-IV in FIG. DETAILED DESCRIPTION

[0012] In one embodiment of the present technology, the first electronic device may be fixed to the bumper body. In this case, the first electronic device and the inner body may define a space between the first electronic device and the inner body in a first direction, and the at least one columnar portion may be adjacent to the space in a second direction. In another embodiment, the first electronic device may be fixed to the interior of the bumper. In this case, a space may exist between the first electronic device and the bumper body in the first direction.

[0013] In one embodiment of the present technology, the at least one columnar portion may include a pair of columnar portions arranged in the second direction. In this case, the first electronic device may be located between the pair of columnar portions. According to this configuration, since the load applied to the bumper body is distributed to the columnar portions, displacement of the bumper body (particularly, displacement of the bumper body relative to the bumper interior) can be more reliably inhibited or reduced than in a configuration in which the bumper interior includes only one columnar portion.

[0014] In one embodiment of the present technology, the front bumper may further include a second electronic device located outside the pair of columnar sections. With this configuration, the columnar sections can mitigate damage to the second electronic device in addition to the first electronic device. In another embodiment, the second electronic device may be located between the columnar sections.

[0015] In one embodiment of the present technology, the second electronic device may include a camera configured to capture an image of an area in front of the vehicle. In another embodiment, the second electronic device may include an antenna that receives radio waves for remote control of the vehicle.

[0016] In one embodiment of the present technology, the first electronic device may include a millimeter wave radar. In another embodiment, the first electronic device may include an antenna that receives radio waves for remote control of the vehicle.

[0017] In one embodiment of the present technology, the bumper body may include a base protruding toward the inner body. In this case, the at least one columnar portion may extend toward the base. The base protruding toward the inner body has a relatively high rigidity compared to other parts of the bumper body. According to this construction, because the columnar portion extends toward the base having high rigidity, the rigidity around the first electronic device and / or the second electronic device is further increased. Compared to a construction in which the bumper interior includes a columnar portion extending toward any other part of the bumper body, this construction can further reduce damage to the first electronic device and / or the second electronic device.

[0018] In one embodiment of the present technology, the front bumper may further include a cover attached to the bumper body from the outside and covering the base from the outside. Since the outside of the base of the bumper body is not exposed, this configuration can improve the flexibility of the shape of the base.

[0019] In one embodiment of the present technology, the top end of the at least one columnar portion may be fixed to a base. This configuration, because the columnar portion and the base are structurally integrated, reliably protects the space between the bumper body and the inner body. Compared to configurations where the top end of the columnar portion is not fixed to the base, this configuration can further mitigate damage to the first and / or second electronic devices.

[0020] In one embodiment of the present technology, the first direction may be the longitudinal direction of the vehicle, and the second direction may be the lateral direction of the vehicle. In another embodiment, the first direction may be the vertical direction. In this case, the second direction may be the longitudinal direction or the lateral direction.

[0021] In one embodiment of the present technology, the bumper body may be configured to be secured to the bumper inner, and the bumper inner may be configured to be secured to the body of the vehicle.

[0022] A front bumper according to one embodiment will be described with reference to the accompanying drawings. Figure 1 A vehicle 100 equipped with the front bumper 10 of this embodiment will be described. In the following description, with respect to the vertical direction of the vehicle 100, the upward direction (i.e., the direction of arrow V in the drawings) is sometimes simply referred to as "up," and the opposite direction, i.e., the downward direction, is sometimes simply referred to as "down." With respect to the lateral direction of the vehicle 100, the leftward direction (i.e., the direction of arrow L in the drawings) when viewed from the passenger compartment of the vehicle 100 is sometimes simply referred to as "left," and the opposite direction is sometimes simply referred to as "right." Similarly, with respect to the longitudinal direction of the vehicle 100, the forward direction (i.e., the direction of arrow F in the drawings) is sometimes simply referred to as "front," and the opposite direction, i.e., the rearward direction, is sometimes simply referred to as "rear."

[0023] Figure 1 The front portion of vehicle 100 is shown. Vehicle 100 includes a pair of wheels 2R, 2L, a pair of headlights 4R, 4L, a body 6, and a front bumper 10. Vehicle 100 travels by driving wheels 2R, 2L. Headlights 4R, 4L illuminate the road ahead of vehicle 100. Body 6 is a sheet metal member that forms a structure protecting a passenger compartment (not shown) of vehicle 100.

[0024] The front bumper 10 is a so-called exterior member mounted on the front of the vehicle 100 and is mainly made of resin. The front bumper 10 includes a bumper body 11b, a cover 11g, a bumper inner 20, a millimeter wave radar 30, and a camera 40. Figure 2 In detail, the front bumper 10 is fixed to the vehicle body 6 of the vehicle 100 via the bumper inner 20. The bumper body 11b is a resin member exposed on the front of the vehicle 100. The cover 11g is a resin member that is fixed from the outside (ie, closer to the vehicle body 100). Figure 1 The millimeter-wave radar 30 is an electronic device for detecting obstacles in front of the vehicle 100. The camera 40 is an electronic device for capturing images of the area in front of the vehicle 100. The detailed structures of the millimeter-wave radar 30 and the camera 40 are well known in the art, so their description will be omitted.

[0025] Will refer to Figure 2 The structure of the front bumper 10 will be described in detail. The bumper body 11b has a portion in its upper portion that is oriented in the lateral direction of the vehicle 100 (ie, Figure 2 The bumper body 11b has a fixing portion 13b extending in the horizontal direction of the fixing portion 13b. The bumper body 11b has a base 13f in the middle part of the fixing portion 13b. The fixing portion 13b and the base 13f are seat surfaces on which structures such as a pair of bosses 16R, 16L and a pair of bosses 17R, 17L are located. First, the electronic device (i.e., the millimeter wave radar 30 and the camera 40) is fixed to the base 13f of the fixing portion 13b. Next, the bumper interior 20 is fixed to the fixing portion 13b of the bumper body 11b.

[0026] The bumper interior 20 includes an inner body 20b, a pair of columnar portions 22R, 22L, a pair of bumper stays 24R, 24L and a pair of through holes 26R, 26L. The inner body 20b extends in the lateral direction of the vehicle 100 and has a cutout along the middle portion of its lower edge. The columnar portions 22R, 22L extend forward from the inner body 20b toward the base 13f of the bumper body 11b. Each of the columnar portions 22R, 22L has a through hole at its top end. The bolt 60 passes through the through holes of the columnar portions 22R, 22L of the bumper interior 20 and is screwed into the bosses 16R, 16L of the base 13f of the bumper body 11b. Similarly, the bolt 60 passes through the through holes 26R, 26L of the inner body 20b and is screwed to the rear surface of the fixing portion 13b of the bumper body 11b (i.e., the distance between the fixing portion 13b and the rear surface). Figure 2 The bumper inner 20 is thus fixed to the bumper body 11b by bolts 60.

[0027] Then, the cover 11g is attached to the bumper body 11b from the front so as to cover the fixing portion 13b. Although not shown in the figure, the cover 11g is fixed by fitting resin clips, tabs, etc. into the through holes of the fixing portion 13b. Thus, the front bumper 10 is completed.

[0028] As in Figure 2 As shown in FIG, the body 6 of the vehicle 100 (see FIG. Figure 1) includes a body portion and a leg portion extending in the transverse direction of the vehicle 100. The vehicle body 6 includes a pair of brackets 8R and 8L. Brackets 8R and 8L are welded to the body portion of the vehicle body 6. Each of the brackets 8R and 8L has a bottom surface extending forward toward the front bumper 10. The bottom surface of each bracket 8R and 8L has a through hole.

[0029] The bumper stays 24R, 24L of the inner body 20b are positioned to face the brackets 8R, 8L, respectively, in the longitudinal direction of the vehicle 100. Specifically, in the bumper stays 24R, 24L located on the right side (ie, Figure 2 The right bumper stay 24R on the left side of the vehicle 100 faces the right bracket 8R on the right side of the brackets 8R, 8L in the longitudinal direction of the vehicle 100. Similarly, the right bumper stay 24R on the left side (ie, Figure 2 The left bumper stay 24L on the right side of the vehicle 100 faces the left bracket 8L on the left side in the longitudinal direction of the vehicle 100.

[0030] Make the completed front bumper 10 from the front (ie, closer to Figure 2 The bumper stays 24R, 24L and the brackets 8R, 8L are then fastened together from above by bolts 50, respectively. Although not shown in the drawings, the bumper inner 20 of the front bumper 10 of this embodiment is also fastened to the headlights 4R, 4L at both ends thereof in the lateral direction of the vehicle 100 (see FIG. Figure 1 ). The front bumper 10 is thus mounted on the vehicle 100 via the bumper inner 20 .

[0031] Will refer to Figure 3 and Figure 4 The detailed structure of the front bumper 10 around the electronic devices 30 and 40 will be described. The following will mainly describe the left side (ie, Figure 3 However, the right columnar portion 22R located on the right side also has a similar shape.

[0032] As described above, the bumper body 11b is fixed to the vehicle body 6 through the bumper inner 20. Accordingly, as in Figure 3 As shown in FIG, the bumper inner 20 is located between the bumper body 11b and the vehicle body 6. The electronic devices 30, 40 are therefore located between the bumper inner 20 and the bumper body 11b. As a result, the inner body 20b of the bumper inner 20 is located in the longitudinal direction of the vehicle 100 (i.e., Figure 3 facing the electronic devices 30 and 40).

[0033] As described above, the base 13f protruding toward the inner body 20b is provided in the middle portion of the fixing portion 13b in the lateral direction of the vehicle 100. The base 13f is a seat surface to which the bumper inner 20 and the electronic devices 30, 40 are fixed. Figure 3 There are a plurality of reinforcing ribs 18 on the side farther from the observer of the bumper body 11b), so that the base 13f has higher rigidity than other parts of the bumper body 11b.

[0034] The millimeter wave radar 30 is fixed to the base 13f via the radar bracket 32. Figure 4 As shown in FIG, the radar bracket 32 ​​is fixed to the base 13f by screws 56 screwed into the boss 12L of the base 13f. The radar bracket 32 ​​has a transversely symmetrical shape. Accordingly, also on the right side of the millimeter wave radar 30 (the millimeter wave radar 30 is away from the base 13f), Figure 4 The radar bracket 32 ​​is fixed to the base 13f by screws 56 that are screwed into the bosses 12R of the base 13f.

[0035] Similarly, the camera 40 is also fixed to the base 13f via the camera bracket 54. More specifically, the camera 40 is fixed to the base 13f by passing the screw 46 through the through hole of the camera bracket 54 and screwing the screw 46 into the bosses 14 and 15 of the base 13f. The columnar portions 22R and 22L of the bumper inner 20 are fixed to the base 13f by bolts 60.

[0036] As in Figure 3 As shown in FIG, because the inner body 20b of the bumper inner 20 is interposed between the bumper body 11b and the vehicle body 6, the space in which each electronic device 30, 40 exists is reduced in the longitudinal direction of the vehicle 100. In other words, because the inner body 20b is interposed between the bumper body 11b and the vehicle body 6, the space behind each electronic device 30, 40 is reduced.

[0037] The front bumper 10 is an exterior member and is exposed to the outside of the vehicle 100. Accordingly, for example, when the vehicle 100 is involved in a head-on collision, a rearward load F1 is applied to the front surface of the front bumper 10. As described above, the bumper body 11b is made of resin. Therefore, when the load F1 is applied to the front surface of the front bumper 10, the base 13f of the bumper body 11b is displaced rearward. As a result, the electronic devices 30, 40 are displaced toward the rear of the vehicle 100 (i.e., at the rear of the vehicle 100) as the base 13f is displaced. Figure 3 Move up in the middle).

[0038] As in Figure 3 As shown in FIG, the left columnar portion 22L is in the left direction (ie, Figure 3The left columnar portion 22L is adjacent to the millimeter-wave radar 30 in the longitudinal direction of the vehicle 100 (in the rightward direction). A length D1 of the left columnar portion 22L in the longitudinal direction of the vehicle 100 is greater than a length D2 of the millimeter-wave radar 30 in the longitudinal direction of the vehicle 100. Accordingly, a space S1 exists between the millimeter-wave radar 30 and the inner body 20b in the longitudinal direction of the vehicle 100. The left columnar portion 22L is also adjacent to the space S1 in the lateral direction of the vehicle 100.

[0039] Moreover, as in Figure 3 and Figure 4 As shown in FIG, the left column portion 22L has a box shape and has side surfaces on its upper side, lower side, right side, and left side. Each side surface of the left column portion 22L extends in the longitudinal direction of the vehicle 100.

[0040] When load F1 is applied to the front bumper 10 and the base 13f of the bumper body 11b shifts rearward, the millimeter-wave radar 30 moves into space S1. At this time, load F1 is transmitted to the left pillar portion 22L via the base 13f of the bumper body 11b. As described above, because each side surface of the left pillar portion 22L extends in the longitudinal direction of the vehicle 100, the rearward load F1 is transmitted to each side surface of the left pillar portion 22L as a compressive load. Compared to the base 13f to which load F1 is transmitted as a bending load, the left pillar portion 22L is less likely to deform in the longitudinal direction of the vehicle 100 due to load F1. In other words, even when the bumper body 11b is displaced by the load F1, the left column portion 22L is able to prohibit or reduce the displacement of the base 13f (particularly, the displacement of the base 13f relative to the inner body 20b) before the millimeter-wave radar 30 is compressed between the base 13f of the bumper body 11b and the inner body 20b of the bumper interior 20.

[0041] As a result, even when a load F1 is applied to the front bumper 10, the left pillar portion 22L maintains space S1 for the millimeter-wave radar 30. As described above, when a load F1 is applied to the front bumper 10 disclosed herein, the millimeter-wave radar 30 can be displaced into the space S1 protected by the left pillar portion 22L. This configuration prevents or suppresses compression of the millimeter-wave radar 30 between the base 13f and the inner body 20b. As a result, the front bumper 10 can mitigate damage to the millimeter-wave radar 30.

[0042] In the front bumper 10, the millimeter-wave radar 30 is located between the pair of columnar sections 22R and 22L, namely, between the left columnar section 22L and the right columnar section 22R located to the right of the left columnar section 22L. As described above, the right columnar section 22R has a similar structure to the left columnar section 22L. Accordingly, the space S1 is protected by the columnar sections 22R and 22L. The load F1 is distributed across the columnar sections 22R and 22L. Compared to a configuration in which the bumper interior 20 only has the left columnar section 22L, this configuration can further reduce damage to the millimeter-wave radar 30.

[0043] As in Figure 3 and Figure 4 As shown in the figure, the front top of the left columnar portion 22L abuts against the rear surface of the base 13f. In other words, the left columnar portion 22L extends toward the base 13f. As described above, because the base 13f protrudes toward the inner body 20b and is reinforced by the reinforcing ribs 18, the base 13f has higher rigidity than other parts of the bumper body 11b. Because the left columnar portion 22L extends toward the highly rigid base 13f, the rigidity around the millimeter-wave radar 30 can be increased. This configuration can further reduce damage to the millimeter-wave radar 30.

[0044] The front top of the left columnar portion 22L is fixed to the base 13f by a bolt 60. The left columnar portion 22L and the base 13f are thus structurally integrated. Specifically, the front top of the left columnar portion 22L (ie, the portion located at the Figure 3 The top end on the lower side in the vehicle 100) in the lateral direction of the vehicle 100 or the vertical direction of the vehicle 100 (ie, from closer to the vehicle 100). Figure 3 The left columnar portion 22L is displaced on the rear surface of the base 13f in a direction from the side of the observer to the side away from the observer, or vice versa. This configuration can more reliably protect the space S1 than a configuration in which the front top end of the left columnar portion 22L is not fixed to the base 13f. In other words, this configuration can further reduce damage to the millimeter wave radar 30.

[0045] As in Figure 3 As shown in FIG, the camera 40 is located outside the columnar portions 22R, 22L. The right columnar portion 22R is positioned in the left direction (ie, Figure 3 The right columnar portion 22R is adjacent to the camera 40 in the right direction (in the vehicle 100). The length D1 of the right columnar portion 22R is greater than the length D3 of the camera 40 in the longitudinal direction of the vehicle 100. Therefore, similar to the millimeter wave radar 30, a space S2 exists between the camera 40 and the inner body 20b in the longitudinal direction of the vehicle 100. This configuration can reduce damage to the camera 40 when a load F1 is applied to the front bumper 10.

[0046] As described above, the cover 11g is removed from the vehicle 100 (see FIG. Figure 1 ) is attached to the fixing portion 13b of the bumper body 11b. Figure 3 and Figure 4 As shown in FIG, cover 11g covers base 13f of fixing portion 13b from the outside. Multiple bosses are provided on the outside of base 13f. Because cover 11g covers base 13f from the outside, the bosses are not exposed to the outside. This configuration can improve the flexibility of the shape of base 13f to which electronic devices 30, 40 and bumper inner 20 are fixed.
