Abstract
Description
Technical Field
[0001] The technology disclosed in this specification relates to a front bumper. In particular, it relates to a front bumper including a bumper body exposed to the outside of the vehicle and a bumper inner member for fixing the bumper body to the vehicle body. Background Art
[0002] A front bumper including a bumper body (referred to as a bumper front face in Japanese Patent Application Laid-Open No. 2004-203158) and a bumper inner member (referred to as a reinforcement member in Japanese Patent Application Laid-Open No. 2004-203158) is disclosed in Japanese Patent Application Laid-Open No. 2004-203158. A plurality of fixing portions between the bumper inner member and the vehicle body (for example, a bottom cover) are connected by a wall thickness portion formed in the bumper inner member. Thus, in the case where a pedestrian collides with the bumper body, the rigidity of the fixing portions between the bumper inner member and the vehicle body is used to suppress deformation of the lower portion of the bumper body. Summary of the Invention
[0003] As an exterior panel, the bumper body needs to be installed with no excessive gap relative to adjacent other components such as the vehicle body and other exterior parts in order to improve the aesthetics of the vehicle. For this purpose, it is important to appropriately maintain the position of the bumper body, and it is required to firmly fix the bumper body to the vehicle body. As described above, the bumper body is fixed to the vehicle body via the bumper inner member. A bumper bracket extending toward the vehicle body is provided in the bumper inner member. In this case, one end of the bumper bracket is fixed to the vehicle body, so the bumper bracket supports the bumper body in the form of a so-called cantilever beam. Therefore, the bumper body fixed to the vehicle body by the bumper bracket is likely to be displaced downward due to the self-weight of the bumper body. To prevent such deformation, it is effective to strengthen the bumper bracket. In particular, in the substrate combined with the vehicle body, it is possible to consider providing reinforcing walls extending in the vertical direction at the periphery of the substrate.
[0004] The strengthened bumper bracket is connected to an inner member main body that supports the bumper body. The inner member main body extends in the vehicle width direction along the inside of the bumper body. Therefore, the inner member main body can support the bumper body from the inside over the entire vehicle width direction. In this way, the front bumper can appropriately maintain the overall position of the bumper body by including the strengthened bumper bracket and the inner member main body that supports the bumper body over the entire vehicle width direction.
[0005] However, a bumper bracket having a reinforcing wall has high rigidity. In addition, the inner member body that extends long in the vehicle width direction also requires a certain degree of rigidity in order to suppress sagging and twisting at both ends of the inner member body. As a result, around the bumper bracket of the front bumper, the rigidity is likely to locally increase due to both the bumper bracket and the inner member body. If the bumper bracket located inside the front bumper has locally high rigidity, when an external force acts on the front bumper, the reaction force of the external force may locally increase. In this specification, a technique is provided that can increase the rigidity of the bumper bracket and suppress the local increase in the rigidity of the bumper inner member including the inner member body and the bumper bracket around the bumper bracket.
[0006] A front bumper according to one aspect disclosed in this specification is mounted on the front part of a vehicle. The front bumper includes a bumper body and a bumper inner member. The bumper body is exposed to the outside of the vehicle. The bumper inner member is disposed inside the bumper body. In addition, the bumper inner member has: an inner member body that extends in the vehicle width direction along the inner surface of the bumper body; and at least one bumper bracket that extends from the inner member body toward the vehicle body and is fixed to the vehicle body. The at least one bumper bracket has: a base plate that is coupled to the vehicle body; and a reinforcing wall that extends in the vertical direction from the periphery of the base plate. At least one of the upper edge and the lower edge of the inner member body that extends in the width direction has a cutout in a range including a position closest to the at least one bumper bracket.
[0007] In the above front bumper, a cutout is provided in the inner member body in accordance with the position of the bumper bracket. The cutout is provided in at least one of the upper edge and the lower edge of the inner member body in a range including a position closest to the bumper bracket. According to such a structure, around the bumper bracket having high rigidity, the rigidity of the bumper inner member locally decreases. Thereby, it is possible to suppress the local increase in the rigidity of the bumper inner member including the inner member body and the bumper bracket around the bumper bracket. In addition, since the cutout provided in the inner member body is located around the bumper bracket, the required rigidity of the inner member body will not be excessively decreased. That is, in the inner member body that extends long in the vehicle width direction, even if a cutout is provided near the bumper bracket, sagging and twisting at both ends of the inner member body are difficult to be amplified.
[0008] Details and further improvements of the technology disclosed in this specification will be described in the following "Detailed Description". BRIEF DESCRIPTION OF THE DRAWINGS
[0009] 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 reference numerals denote like elements, where:
[0010] Figure 1 The front view of a vehicle equipped with the front bumper of the mounting embodiment.
[0011] Figure 2 The perspective view of the front bumper of the embodiment after being disassembled.
[0012] Figure 3 It is Figure 1 The enlarged rear view of the range surrounded by the double-dashed line III.
[0013] Figure 4 It is Figure 3 The cross-sectional view along line IV-IV. Detailed implementation mode
[0014] In an embodiment of the present technology, the reinforcing wall can be provided on each of the two side edges located on both sides in the width direction of the periphery of the substrate. According to such a structure, the rigidity of the bumper bracket becomes higher, and the position of the bumper main body can be maintained more appropriately.
[0015] In an embodiment of the present technology, the at least one bumper bracket can be a pair of bumper brackets arranged in the width direction. For example, in the case of a structure having only one bumper bracket, a torsional moment is likely to be generated with respect to the bumper bracket. As a result, the position of the bumper main body is likely to shift. According to such a structure, since the generation of the torsional moment with respect to the bumper bracket is suppressed by the pair of bumper brackets, the position of the bumper main body can be maintained more appropriately.
[0016] In an embodiment of the present technology, the cutout can be continuously formed from the position closest to one of the pair of bumper brackets to the position closest to the other of the pair of bumper brackets. Between the pair of bumper brackets, the influence caused by each bumper bracket will occur. Therefore, at a position not close to the bumper bracket, the rigidity of the bumper inner member is also likely to increase. Therefore, between the pair of bumper brackets, by continuously forming the cutout of the inner member main body, the rigidity of the bumper inner member can be appropriately reduced.
[0017] In an embodiment of the present technology, the cutout can be provided on the lower edge of the inner member main body. However, in other embodiments, the cutout can also be provided on the upper edge of the inner member main body.
[0018] In one embodiment of the present technology, at least one electronic device may be further provided between the bumper main body and the inner member main body. In this case, at least a part of the at least one electronic device may be exposed from the cutout. With such a structure, it is possible to approach the exposed portion of the electronic device via the bumper inner member. That is, maintenance of the electronic device can be performed without disassembling the bumper inner member, and maintenance of the electronic device becomes easy.
[0019] In one embodiment of the present technology, the bumper main body may include a pedestal protruding toward the inner member main body. The at least one electronic device may be fixed to the pedestal. In this case, the front bumper may further include a cover. The cover may be attached to the bumper main body from the outside and cover the pedestal from the outside. With such a structure, the pedestal for fixing the electronic device can be covered by the cover, so that the degree of freedom in the shape of the pedestal can be increased.
[0020] In one embodiment of the present technology, the at least one electronic device may include a millimeter-wave radar. However, in other embodiments, the at least one electronic device may also include an antenna that receives radio waves for remote operation of the vehicle.
[0021] In one embodiment of the present technology, the at least one electronic device may include a camera that photographs a region in front of the vehicle. However, in other embodiments, the at least one electronic device may also include an antenna that receives radio waves for remote operation of the vehicle.
[0022] The front bumper of the embodiment will be described with reference to the drawings. First, Figure 1 a vehicle 100 equipped with the front bumper 10 of the embodiment will be described. In addition, hereinafter, the upper part of the vehicle 100 (that is, the direction of the arrow V in the figure) may be simply referred to as "up", and the lower part of the vehicle on the opposite side may be simply referred to as "down". Similarly, in the vehicle width direction of the vehicle 100, the left direction (that is, the direction of the arrow L in the figure) as observed from the occupants in the passenger compartment of the vehicle 100 may be simply referred to as "left", and the opposite side may be simply referred to as "right". Similarly, the front direction of the vehicle 100 (that is, the direction of the arrow F in the figure) may be simply referred to as "front", and the rear of the vehicle on the opposite side may be simply referred to as "rear".
[0023] Figure 1 The front part of the vehicle 100 is shown. The vehicle 100 includes a pair of wheels 2R, 2L, a pair of headlamps 4R, 4L, a vehicle body 6, and a front bumper 10. The vehicle 100 travels by driving a pair of wheels 2R, 2L. The pair of headlamps 4R, 4L are lamps that irradiate the front of the vehicle 100. The vehicle body 6 is a sheet metal part that constitutes a structure for protecting the passenger compartment (not shown) of the vehicle 100.
[0024] The front bumper 10 is an exterior component mounted on the front of the vehicle 100 and is mainly made of resin. The front bumper 10 includes a bumper main body 11b, a cover 11g, a bumper inner member 20, a millimeter-wave radar 30, and a camera 40. Details will be described with reference to Figure 2 which will be described later. The front bumper 10 is fixed to the vehicle body 6 of the vehicle 100 via the bumper inner member 20. The bumper main body 11b is a resin component exposed at the front of the vehicle 100. The cover 11g is mounted on the bumper main body 11b from the outside (i.e., Figure 1 the near side of the paper surface). 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 photographing the area in front of the vehicle 100. Since the detailed structures of the millimeter-wave radar 30 and the camera 40 are known, the description thereof is omitted here.
[0025] Refer to Figure 2 to describe the details of the structure of the front bumper 10. A pedestal 13 extending in the vehicle width direction of the vehicle 100 is provided on the upper part of the bumper main body 11b. Structures such as a plurality of protrusions 16 are arranged on the pedestal 13. First, each electronic device (i.e., the millimeter-wave radar 30 and the camera 40) is fixed to the back surface of the pedestal 13 (i.e., Figure 2 the inner surface of the paper surface). After that, the bumper inner member 20 is fixed to the back surface of the pedestal 13 of the bumper main body 11b.
[0026] The bumper inner member 20 includes an inner member main body 20b, a pair of bumper brackets 22R, 22L, and a plurality of through holes 26. The inner member main body 20b extends in the vehicle width direction (i.e., Figure 2 the left-right direction of the paper surface), and a notch 21 is provided at the center of the lower edge thereof. Bolts 60 are inserted through each of the plurality of through holes 26 of the inner member main body 20b. Each bolt 60 is screwed with the corresponding protrusion 16 among the plurality of protrusions 16 through the corresponding through hole in the plurality of through holes 26. Thus, the bumper inner member 20 is fixed to the bumper main body 11b.
[0027] Next, the resin cover 11g is mounted from the front of the bumper main body 11b so as to cover the pedestal 13. Although not shown in the figure, the cover 11g is fixed by fitting resin clips, claws, etc. into the through holes provided in the pedestal 13. Thus, the front bumper 10 is completed.
[0028] As Figure 2 shown, the vehicle body 6 of the vehicle 100 (refer to Figure 1 ) includes a main body portion and legs extending in the vehicle width direction. The vehicle body 6 includes a pair of brackets 8R, 8L. The pair of brackets 8R, 8L are respectively welded to the main body portion of the vehicle body 6. The pair of brackets 8R, 8L respectively have bottom surfaces extending forward toward the front bumper 10. Through holes are formed in the bottom surfaces of the pair of brackets 8R, 8L.
[0029] A pair of bumper brackets 22R and 22L of the inner member main body 20b are located at positions facing a pair of brackets 8R and 8L in the front-rear direction. Specifically, the right bumper bracket 22R of the pair of bumper brackets 22R and 22L, which is on the right side (i.e., Figure 2 the left side of the paper surface shown) faces the right bracket 8R of the pair of brackets 8R and 8L in the front-rear direction. Similarly, the left bumper bracket 22L, which is on the left side (i.e., Figure 2 the right side of the paper surface shown), faces the left bracket 8L on the left side in the front-rear direction.
[0030] The completed front bumper 10 approaches the vehicle body 6 from the front (i.e., Figure 2 the near front side of the paper surface shown), and the lower surfaces of the pair of bumper brackets 22R and 22L respectively abut against the bottom surfaces of the corresponding ones of the pair of brackets 8R and 8L. Thereafter, through bolts 50, the pair of bumper brackets 22R and 22L and the opposing brackets are fastened from above. It should be noted that although not shown in the figure, the end portions on both sides in the vehicle width direction of the bumper inner member 20 of the front bumper 10 in the embodiment are also fastened to a pair of headlamps 4R and 4L (refer to Figure 1 ). In this way, the front bumper 10 is mounted on the vehicle 100 via the bumper inner member 20.
[0031] Refer to Figure 3 , Figure 4 to describe the detailed structure around the pair of bumper brackets 22R and 22L. Figure 3 is an enlarged view when observing the periphery of the pair of bumper brackets 22R and 22L from the rear in a state where the front bumper 10 has been removed from the vehicle body 6 (refer to Figure 2 ). It should be noted that hereinafter, mainly the left bumper bracket 22L of the pair of bumper brackets 22R and 22L will be described, but the right bumper bracket 22R on the right side has the same shape.
[0032] As described above, the left bumper bracket 22L extends rearward from the inner member main body 20b toward the vehicle body 6. As Figure 3 shown, the inner member main body 20b is fixed to the pedestal 13 of the bumper main body 11b by a plurality of bolts 60. The inner member main body 20b supports the bumper main body 11b from the inside. In addition, as Figure 4 shown, the rear end of the left bumper bracket 22L extending rearward from the inner member main body 20b is fixed to the left bracket 8L by a bolt 50. In this way, the bumper main body 11b is fixed to the vehicle body 6 of the vehicle 100 via the bumper inner member 20.
[0033] Therefore, as Figure 4As shown, the bumper main body 11b having a hollow shape is not directly supported by the vehicle body 6. The left bumper bracket 22L of the bumper inner member 20 supports the bumper main body 11b in the form of a so-called cantilever beam. Therefore, the bumper main body 11b is liable to displace downward due to its own weight.
[0034] Therefore, in addition to being fastened (i.e., joined) to the left substrate 23L of the left bracket 8L by bolts 50, the left bumper bracket 22L also has a left reinforcing wall 24L. The left reinforcing wall 24L is a wall extending in the vertical direction from the periphery of the left substrate 23L. As Figure 4 shown, the left reinforcing wall 24L extends more upward toward the inner member main body 20b side. That is, the height of the left reinforcing wall 24L is higher toward the root side of the left reinforcing wall 24L. The left reinforcing wall 24L strengthens the left bumper bracket 22L. The left reinforcing wall 24L particularly suppresses the downward displacement of the front part of the left bumper bracket 22L. As a result, the left reinforcing wall 24L can suppress the downward displacement of the bumper main body 11b. That is, the left bumper bracket 22L can appropriately hold the position of the bumper main body 11b by using the left reinforcing wall 24L. Thus, the bumper main body 11b does not displace downward. Therefore, for example, the bumper main body 11b is mounted without excessive gaps relative to a pair of headlamps 4R, 4L (refer to Figure 1 ). As a result, the aesthetics around the bumper main body 11b can be improved.
[0035] As Figure 3 shown, the left reinforcing wall 24L is formed over the entire periphery of the left substrate 23L. That is, the left reinforcing wall 24L is provided on each of the two side edges located on both sides in the vehicle width direction (i.e., Figure 3 the left - right direction of the paper surface in the figure) of the periphery of the left substrate 23L. Thereby, the rigidity of the left reinforcing wall 24L is higher. As a result, the left reinforcing wall 24L can further suppress the downward displacement of the bumper main body 11b.
[0036] Moreover, as Figure 3 shown, a right bumper bracket 22R is arranged to the right of the left bumper bracket 22L. That is, the pair of bumper brackets 22R, 22L are arranged adjacent to each other in the vehicle width direction (i.e., Figure 3are arranged in the left - right direction of the paper surface). The right bumper bracket 22R also has a right reinforcing wall 24R that extends in the up - down direction over the entire circumference of the right substrate 23R. The bumper inner member 20 supports the bumper main body 11b on the vehicle body 6 by a pair of bumper brackets 22R and 22L. For example, in a structure where the bumper main body 11b is supported on the vehicle body 6 only by the left bumper bracket 22L, a torsional moment is likely to be generated with respect to the left bumper bracket 22L. In addition, since the load applied to the left bumper bracket 22L becomes larger, it is necessary to reinforce the left bumper bracket 22L more firmly. By supporting the bumper main body 11b on the vehicle body 6 by a pair of bumper brackets 22R and 22L, the generation of torsional moment can be suppressed, and the load applied to one left bumper bracket 22L can be reduced. Thereby, the position of the front bumper 10 can be appropriately maintained.
[0037] In addition, as described above, the bumper main body 11b and the bumper inner member 20 of the front bumper 10 are each made of resin. Therefore, compared with the vehicle body 6 made of a metal plate, the bumper main body 11b and the bumper inner member 20 are each prone to elastic deformation. As Figure 4 shown, there is a space in the front - rear direction between the bumper main body 11b and the vehicle body 6. Thus, when an external force acts on the front bumper 10 during the running of the vehicle 100, the resin - made front bumper 10 deforms backward toward the space. Thereby, the reaction force of the front bumper 10 with respect to the external force becomes smaller.
[0038] However, as described above, the pair of bumper brackets 22R and 22L of the bumper inner member 20 firmly fix the bumper main body 11b to the vehicle body 6. Moreover, the inner member main body 20b extends along the inner side surface (i.e., Figure 3 the near - front side surface of the paper surface) of the bumper main body 11b and is fixed to the pedestal 13 of the bumper main body 11b by a plurality of bolts 60, thereby supporting the bumper main body 11b from the inside. Moreover, the inner member main body 20b also has high rigidity in order to suppress torsion at both ends in the vehicle width direction of itself. At the portion where the inner member main body 20b exists between the bumper main body 11b and the vehicle body 6, a double - structure of the bumper main body 11b and the inner member main body 20b is formed, and the rigidity of this portion of the front bumper 10 becomes high. In particular, at the portion where the pair of bumper brackets 22R and 22L are arranged, the rigidity of the front bumper 10 locally becomes high due to both the inner member main body 20b and the pair of bumper brackets 22R and 22L. As a result, when an external force acts on the front bumper 10, the reaction force of the external force may locally become high.
[0039] As Figure 3As shown, a cutout 21 is provided at the lower edge of the inner member main body 20b directly below a pair of bumper brackets 22R and 22L. The edge of the cutout 21 passes through the point P1 closest to the left bumper bracket 22L and extends along the width direction of the vehicle 100 (i.e., Figure 3 the left - right direction of the paper surface of
[0040] while being displaced in the vertical direction). The cutout 21 reduces the height of the inner member main body 20b. That is, the cutout 21 reduces the cross - sectional area of the inner member main body 20b. As a result, at the portion of the inner member main body 20b where the cutout 21 is provided, the overlapping area of the bumper main body 11b and the inner member main body 20b decreases, and thus the rigidity decreases. In this way, the cutout 21 can prevent the rigidity of the bumper inner member 20 including the inner member main body 20b and the pair of bumper brackets 22R and 22L from locally becoming too high. Figure 1 The cutout 21 is located directly below the pair of bumper brackets 22R and 22L. In other words, the cutout 21 is located near the pair of bumper brackets 22R and 22L. Therefore, even if the rigidity of the inner member main body 20b decreases due to the cutout 21, the pair of bumper brackets 22R and 22L can compensate for the decreased rigidity of the inner member main body 20b. Thus, in the inner member main body 20b that extends long in the width direction of the vehicle 100 (
[0041] with reference), even if the cutout 21 is provided near the pair of bumper brackets 22R and 22L, sagging and torsion at both ends in the width direction of the inner member main body 20b are difficult to be amplified.
[0042] As Figure 3 shown, the millimeter - wave radar 30 is fixed to the pedestal 13 of the bumper main body 11b by three screws 34. The uppermost screw 34 among the three screws 34 is fastened or removed via a maintenance hole 28 formed in the inner member main body 20b. A wire harness 32 is connected to the lower part of the millimeter - wave radar 30. The wire harness 32 passes through an opening provided in the pedestal 13 of the bumper main body 11b and extends to the outside of the pedestal 13 (i.e., Figure 3is disposed on the inner side of the paper surface). The cutout 21 exposes the lower part of the millimeter-wave radar 30. More specifically, in a state where the front bumper 10 is detached from the vehicle body 6, an operator who is preparing the front bumper 10 can visually confirm a part of the millimeter-wave radar 30 from the rear via the cutout 21. Thus, the operator can remove the screw 34 that fixes the millimeter-wave radar 30 to the pedestal 13 of the bumper main body 11b, for example, without detaching the bumper inner member 20 from the bumper main body 11b. Moreover, when maintaining the millimeter-wave radar 30, the operator can confirm the state of the millimeter-wave radar 30 without detaching the bumper inner member 20. In addition, the operator can remove the wiring harness 32 from the millimeter-wave radar 30 without detaching the bumper inner member 20. That is, the maintenance of the millimeter-wave radar 30 becomes easy.
[0043] Similarly, the camera 40 is also exposed from the cutout 21. Therefore, the operator can remove the screw 44 that fixes the camera 40 to the pedestal 13 without detaching the bumper inner member 20. That is, the operator can easily perform the maintenance of the camera 40.
[0044] As Figure 4 shown, the pedestal 13 for fixing each electronic device (i.e., the millimeter-wave radar 30 and the camera 40) protrudes toward the inner member main body 20b. The pedestal 13 is covered from the outside (i.e., Figure 4 the left side of the paper surface) by the cover 11g. That is, the pedestal 13 is not exposed to the outside by the cover 11g. Thus, regardless of the external design shape of the front bumper 10, the position of the pedestal 13 in the front-rear direction can be aligned with the positions of the respective electronic devices 30, 40. That is, the degree of freedom in the shape of the pedestal 13 can be increased.
[0045] As described above, although the embodiments have been described in detail, they are merely illustrative and do not limit the claims. The technology described in the claims includes technologies obtained by various modifications and changes to the specific examples illustrated above. The following are examples of modifications of the above-described embodiments.
[0046] (Modification Example 1) In the above-described front bumper 10, the left reinforcing wall 24L is formed over the entire circumference of the left substrate 23L. In this modification example, the left reinforcing wall 24L may be formed on a part of the circumference of the left substrate 23L. For example, the left reinforcing wall 24L may be provided only on the right-side circumference of the circumference of the left substrate 23L. In this case, the right reinforcing wall 24R may be provided only on the left-side circumference of the circumference of the right substrate 23R.
[0047] (Modification Example 2) In the above front bumper 10, the bumper inner member 20 includes a pair of bumper brackets 22R and 22L. In this modification example, the bumper inner member 20 may, for example, include only one bumper bracket at the center in the vehicle width direction of the vehicle 100. In a further modification example, the bumper inner member 20 may include three or more bumper brackets.
[0048] (Modification Example 3) The cutout 21 of the above front bumper 10 is formed continuously from point P1 to point P2. In this modification example, it may also be that a first cutout whose edge passes through point P1 and a second cutout whose edge passes through point P2 are provided at the lower edge of the inner member main body 20b.
[0049] (Modification Example 4) In this modification example, the cutout 21 may also be provided at the upper edge of the inner member main body 20b.
[0050] (Modification Example 5) In this modification example, the millimeter-wave radar 30 and the camera 40 may not be exposed from the cutout 21.
[0051] (Modification Example 6) The bumper main body 11b may not include the pedestal 13. In this case, the millimeter-wave radar 30 may be directly fixed to the back surface of the bumper main body 11b.
[0052] (Modification Example 7) The front bumper 10 may not include the cover 11g. In this case, the millimeter-wave radar 30 may be directly fixed to the back surface of the portion of the bumper main body 11b that is exposed to the outside.
[0053] (Modification Example 8) In the modification example, the front bumper 10 may not include the millimeter-wave radar 30 and the camera 40. That is, the electronic devices can be omitted. In a further modification example, an antenna that receives a signal for remote operation of the vehicle 100 may be arranged between the bumper main body 11b and the inner member main body 20b instead of the millimeter-wave radar 30 or the camera 40, for example.

In addition, the technologies illustrated in this specification or the drawings can achieve multiple purposes simultaneously, and achieving one of the purposes itself has technical usefulness.
