Description

[Technical Field]

[0001] The present invention relates to a door beam catcher structure that connects the end of a door beam provided in a vehicle door to the vehicle body side. [Background technology]

[0002] Patent Document 1 discloses a door beam catcher structure that connects the end of a door beam provided in a vehicle door to the vehicle body, in which the rear end of a door beam (rear door lower beam) installed in a rear door is engaged with a rear quarter portion (vehicle body) via a catcher mechanism (rear door catcher mechanism) provided at the bottom of a C-pillar (rear pillar). As shown in Figure 3 of Patent Document 1, this catcher mechanism is composed of an insertion member that protrudes toward the rear of the vehicle from the rear end of a metal plate material that constitutes the rear door, and a receiving member provided at the bottom of the C-pillar.

[0003] According to the catcher mechanism described in Patent Document 1, for example, when a load caused by a side collision (side impact) is applied to the rear door, the door beam is pushed inward in the vehicle width direction (toward the passenger compartment) and deformed, and a tensile force acts on the catcher mechanism in the longitudinal direction of the vehicle. In this case, the engagement portion of the catcher mechanism engages with the fitting groove, restricting their relative movement. This restricts the movement of the door beam in the longitudinal direction of the vehicle. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6832762 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the conventional structure described in Patent Document 1, the engaging member (hook) of the catcher mechanism extends rearward from the rear end of the rear door, so when the longitudinal middle part of the door beam is pushed toward the passenger compartment by the load of a side collision, there is a risk that the engaging member will move in a direction rotating outward around the rear end of the rear door, which may cause the engaging member to become disengaged from the receiving member.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a door beam catcher structure that has a simple configuration and can effectively prevent the catcher structure from disengaging during a side collision of a vehicle, thereby improving the safety of vehicle traffic while suppressing a decrease in traffic smoothness. [Means for solving the problem]

[0007] In order to solve the above problems, the door beam catcher structure of the present invention includes a door (14A) attached to a vehicle body (10) so as to be able to open and close, and a catcher mechanism (50) for connecting the door (14A) to a vehicle body side member (17a) when the door (14A) is closed. The door (14A) includes an inner panel (20) and an outer panel (22) provided on the inside and outside in the vehicle width direction, respectively, and a catcher mechanism (50) for connecting the door (14A) to a vehicle body side member (17a) disposed between the inner panel (20) and the outer panel in the vehicle width direction. and a long door beam (40) extending in the width direction, and the catcher mechanism (50) is composed of an engaging member (60) connected to an end (40b) of the door beam (40) and an engaged portion (70) provided on a member (17a) on the vehicle body side and engaging the engaging member (60), and is characterized in that when the door (14A) is closed, the end (40b) of the door beam (40), the engaging member (60) of the catcher mechanism (50), and the engaged portion (70) are arranged in positions where they overlap each other when viewed from the vehicle width direction.

[0008] In addition, in this catcher structure, the engaging member (60) includes a protruding portion (62) that protrudes from the end portion (40b) of the door beam (40) toward the inside in the vehicle width direction, and the engaged portion (70) may include an insertion hole (70) that opens toward the outside in the vehicle width direction and into which the protruding portion (62) is inserted.

[0009] According to the door beam catcher structure of the present invention, when a load due to a side collision (side impact) is input to the door beam, the door beam is displaced inward in the vehicle width direction (toward the passenger compartment) due to the load, causing the engaging member to be displaced in a direction pushing into the engaged portion, thereby effectively reducing the risk of the protruding portion of the engaging member coming out of the insertion hole in the engaged portion. This makes it possible to prevent the catcher structure from disengaging during a side impact with a simple configuration. Therefore, a tensile force can be more reliably applied to the door beam in its longitudinal direction, effectively preventing the door beam from deflecting inward in the vehicle width direction (toward the passenger compartment) due to the load caused by the side impact.

[0010] In this catcher structure, the protrusion (62) of the engaging member (60) may be elongated such that its longitudinal direction (L1) extends in a direction intersecting the longitudinal direction (L2) of the door beam (40).

[0011] According to this configuration, when the load of a vehicle side collision causes the longitudinal center portion of the door beam to deform and be pushed closer to the passenger compartment than the opposite ends, displacing the engaging member toward the longitudinal center of the door beam, the protruding portion of the engaging member makes planar contact with the inner surface of the insertion hole on the door beam side (so-called surface contact), thereby more effectively preventing the protruding portion from slipping out of the insertion hole. That is, because the protruding portion of the engaging member is elongated with its longitudinal direction extending in a direction intersecting the longitudinal direction of the door beam, the longitudinal side of the protruding portion makes planar contact with the inner surface of the opposing insertion hole, thereby improving the contact resistance (friction resistance) between the protruding portion and the insertion hole. Furthermore, since the load applied to the contact portion between the protruding portion and the insertion hole can be effectively distributed and absorbed, disengagement of the catcher mechanism can be more effectively prevented, even under heavy loads.

[0012] This catcher structure may also include a bracket (80) for attaching the end (40b) of the door beam (40) to the inner panel (20), and the engaging member (60) may be fixed to the bracket (80).

[0013] With this configuration, the engaging member is fixed to the end of the door beam via the bracket, preventing relative displacement between the door beam and the engaging member. This allows a tensile force to be applied to the door beam in its longitudinal direction more reliably, more effectively preventing the longitudinal center of the door beam from being displaced (deformed) inward in the vehicle width direction (toward the passenger compartment).

[0014] In addition, with this configuration, the engaging member is fixed to the end of the door beam via a bracket made of a plate-shaped material that is relatively easy to process, which makes it possible to simplify the manufacturing process of the vehicle (car body), improve manufacturing efficiency, and reduce costs compared to when the engaging member is fixed directly to the end of the door beam.

[0015] In addition, in this catcher structure, the bracket (80) has a pair of extension portions (82, 82) extending in the longitudinal direction of the door beam (40) on both sides (upper and lower sides in the embodiment described below) of the direction intersecting the longitudinal direction relative to the end portion (40b) of the door beam (40), and the engaging member (60) may be fixed to the pair of extension portions (82, 82) of the bracket (80).

[0016] According to this configuration, the engaging member is fixed to the extension portion of the bracket provided on both sides (upper and lower sides) of the end of the door beam, thereby preventing the engaging member from moving in a direction that would cause it to fall on both sides (upper and lower sides) of the door beam in a direction that intersects with the longitudinal direction in the event of a side collision of the vehicle.

[0017] In addition, in this catcher structure, the engaging member (60) is composed of a first member (60A) consisting of a plate-like member with a substantially L-shaped cross section, which has a first mounting portion (61a) attached to the door (14A) and a first protruding portion (62a) extending inward in the vehicle width direction from the first mounting portion (61a), and a second member (60B) consisting of a plate-like member with a substantially L-shaped cross section, which has a second mounting portion (61b) attached to the door (14A) and the second protruding portion (61b) extending inward in the vehicle width direction from the second mounting portion (61b), and the first protruding portion (62a) of the first member (60A) and the second protruding portion (62b) of the second member (60B) are overlapped with each other, and the first mounting portion (61a) of the first member (60A) and the second mounting portion (61b) of the second member (60B) may extend in different directions from each other.

[0018] With this configuration, the first and second members constituting the engaging member can be formed by bending, improving the productivity of the vehicle body. Also, by overlapping the first protruding portion and the second protruding portion and extending the first and second mounting portions in different directions, it is possible to prevent the first and second protruding portions from tipping over (displacing the first and second members in the direction in which the first and second protruding portions tilt), which more reliably prevents the protruding portion of the engaging member from coming out of engagement with the insertion hole.

[0019] The reference numerals in parentheses above indicate, for reference, the drawing reference numbers of corresponding components in the embodiments described below. [Effects of the Invention]

[0020] The door beam catcher structure of the present invention has a simple configuration and can effectively prevent the catcher structure from disengaging during a side collision of the vehicle, thereby improving the safety of vehicular traffic while suppressing a decrease in traffic smoothness.

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the terms "front" and "rear" refer to the front side, which is the forward direction of a vehicle body (vehicle) described below, or the rear side, which is the reverse direction. Furthermore, the terms "left" and "right" refer to the left and right sides in the vehicle width direction when facing the forward direction (front side) of the vehicle body (vehicle). Furthermore, the terms "up" and "down" refer to the up-down direction (vertical up-down direction) of the vehicle body (vehicle).

[0023] FIG. 1 is a diagram showing a portion of the side of a vehicle body to which a door beam catcher structure according to one embodiment of the present invention is applied. As shown in the figure, a vehicle equipped with a door beam catcher structure according to one embodiment of the present invention is configured with a side door 14 provided on a vehicle body 10. The side door 14 is composed of a front door 14A and a rear door 14B. The vehicle body 10 is also provided with a door opening 16 to which the side door 14 is attached so as to be able to open and close. The door opening 16 has a front door opening 16A and a rear door opening 16B. In the following description, only the front door 14A and the front door opening 16A of the side door 14 and the door opening 16 will be described, and a description of the rear door 14B and the rear door opening 16B will be omitted.

[0024] The front door 14A is composed of a door body 14a that opens and closes the front door opening 16A. The door body 14a of the front door 14A includes an inner panel 20 provided on the inside in the vehicle width direction, an outer panel (not shown) provided on the outside in the vehicle width direction of the inner panel 20, and a door beam 40 provided between the inner panel 20 and the outer panel in the vehicle width direction. The inner panel 20 and the outer panel are plate-shaped metal members, and the door beam 40 is a long (rod-shaped) metal member.

[0025] The door beam 40 is disposed within the door body 14a of the front door 14A and is a cylindrical member having a hollow circular cross section that extends along the fore-and-aft direction of the vehicle body 10 (more specifically, the diagonal fore-and-aft direction sloping from top to bottom from the front to the rear).

[0026] A front end 40a of the door beam 40 is fixed to a front upper portion 20a of the inner panel 20. A rear end 40b of the door beam 40 is fixed to a rear lower portion 20b of the inner panel 20. That is, the door beam 40 extends obliquely from a front upper portion (near a front upper corner) of the front door 14A to a rear lower portion (near a rear lower corner).

[0027] The vehicle body 10 of this embodiment is equipped with a catcher mechanism 50 for connecting the front door 14A to a center pillar 17, which is a vehicle body component, when the front door 14A is closed. FIG. 2 is a view of the rear lower end of the front door 14A as seen from the front side, illustrating the rear end 40b of the door beam 40 and its vicinity. FIG. 3 is a view of the rear lower end of the front door 14A as seen from the back side, illustrating an engagement hook 60 of the catcher mechanism 50. FIG. 4 is a view of the rear lower end of the front door opening 16A, illustrating an insertion hole 70 of the catcher mechanism 50 provided on the vehicle body 10 side. FIG. 5 is a view showing a cross section at a position corresponding to the view of the arrow AA in FIG. 3. Note that FIG. 5 illustrates not only a cross section of the front door 14A, but also a cross section of the vehicle body 10 (center pillar 17 and front door opening 16A).

[0028] The catcher mechanism 50 is configured to include an engagement hook (engagement member) 60 connected to the rear end 40b of the door beam 40, and an insertion hole (engaged portion) 70 provided around the front door opening 16A of the vehicle body 10 (near the lower end 17a of the center pillar 17). The insertion hole 70 is a hole into which the engagement hook 60 is inserted and engaged. When the front door 14A is closed, the rear end 40b of the door beam 40, the engagement hook 60 of the catcher mechanism 50, and the insertion hole 70 are positioned so as to overlap each other when viewed in the vehicle width direction (substantially the same positions in the front-rear and up-down directions).

[0029] As shown in FIG. 2, a bracket 80 is provided to attach the rear end 40b of the door beam 40 to the inner panel 20. The rear end 40b of the door beam 40 is fixed to the front surface 20c (the outer surface in the vehicle width direction) of the inner panel 20 via the bracket 80. The engagement hook 60 is fixed to the bracket 80. That is, the engagement hook 60 attached to the back surface 20d (the inner surface in the vehicle width direction) of the inner panel 20 is fixed to the bracket 80 by fastening a bolt 85. That is, the bracket 80 attached to the front surface 20c of the inner panel 20 and the engagement hook 60 attached to the back surface 20d are connected and fixed by fastening the bolt 85 that penetrates the inner panel 20. Note that a reinforcing member 87, which is a metal plate-shaped member, is interposed between the back surface 20d of the inner panel 20 and the engagement hook 60.

[0030] 2, the bracket 80 is a member formed by bending a metal plate material, and includes a beam fixing portion 81 that fixes the rear end portion 40b of the door beam 40, and a pair of extending portions 82, 82 that extend along the longitudinal direction L2 of the door beam 40 on the upper side (one side in a direction intersecting the longitudinal direction L2 of the door beam 40) and the lower side (the other side in a direction intersecting the longitudinal direction L2 of the door beam 40) of the beam fixing portion 81. The beam fixing portion 81 is a portion formed by bending the plate material that constitutes the bracket 80 into a curved surface so as to fit along the outer surface (cylindrical surface) of the rear end portion 40b of the door beam 40, and the rear end portion 40b of the door beam 40 is clamped between the beam fixing portion 81. Bolts 85 are inserted into bolt holes (not shown) formed in the pair of extending portions 82, 82 of the bracket 80 for fixation. Therefore, the engagement hook 60 is fixed to a pair of extensions 82, 82 of the bracket 80 (via the bolts 85).

[0031] The engagement hook 60 is composed of a first member 60A and a second member 60B formed by bending a metal plate-like member. The first member 60A is a plate-like member having a substantially L-shaped cross section, and includes a first mounting portion (mounting surface) 61a attached to the front door 14A (the inner panel 20 and the bracket 80) and a first protruding portion (insertion portion) 62a extending from an end of the first mounting portion 61a toward the inside in the vehicle width direction (toward the passenger compartment). The second member 60B is a plate-like member having a substantially L-shaped cross section, and includes a second mounting portion (mounting surface) 61b attached to the front door 14A (the inner panel 20 and the bracket 80) and a second protruding portion (insertion portion) 62b extending from the second mounting portion 61b toward the inside in the vehicle width direction (toward the passenger compartment).

[0032] The first protrusion 62a of the first member 60A and the second protrusion 62b of the second member 60B are overlapped with each other. As shown in Fig. 3, the first protrusion 62a and the second protrusion 62b are elongated portions extending in a vertical direction (more specifically, a diagonal vertical direction inclined from the rear side to the front side) in which their longitudinal direction (the direction of arrow L1 in Fig. 3) intersects with the longitudinal direction of the door beam 40 (the direction of arrow L2 in Fig. 3). As shown in Fig. 5 and other figures, the first mounting portion 61a of the first member 60A extends from a base portion of the first protrusion 62a toward the front side of the vehicle body 10, and the second mounting portion 61b of the second member 60B extends from a base portion of the second protrusion 62b toward the rear side of the vehicle body 10, and these extend in different directions. That is, the first member 60A and the second member 60B of the engaging hook 60 are both plate-shaped members with an approximately L-shaped cross section, and are butted together in opposite directions so that they are back-to-back, and in this state are attached to the back surface 20d of the inner panel 20 of the front door 14A.

[0033] The insertion hole 70 is formed as a bottomed recess that opens outward in the vehicle width direction and is recessed inward in the vehicle width direction (toward the passenger compartment) near the lower end 17a of the center pillar 17 of the vehicle body 10 and near the rear lower part of the front door opening 16A. The insertion hole 70 is provided at a position that overlaps with the protrusion 62 (first protrusion 62a and second protrusion 62b) of the engagement hook 60 when viewed from the vehicle width direction with the front door 14A closed, so that the protrusion 62 of the engagement hook 60 is inserted into and engaged with the insertion hole 70 when the front door 14A is closed. As shown in FIG. 5 , when the protrusion 62 of the engagement hook 60 is inserted into the insertion hole 70, the surface of the protrusion 62 of the engagement hook 60 (the front surface of the first protrusion 62a) and the front inner surface 70a of the insertion hole 70 are substantially parallel to each other and are arranged opposite each other.

[0034] As described above, the door beam catcher structure of this embodiment includes the front door 14A attached to the vehicle body 10 so as to be able to open and close, and the catcher mechanism 50 for connecting the front door 14A to the lower end 17a of the center pillar 17, which is a vehicle body member, when the front door 14A is closed. The front door 14A includes an inner panel 20 and an outer panel provided on the inside and outside of the vehicle body 10 in the vehicle width direction, and an elongated door beam 40 disposed between the inner panel 20 and the outer panel in the vehicle width direction and extending in the front-to-rear direction of the vehicle body 10. The catcher mechanism 50 is composed of an engagement hook (engagement member) 60 connected to the rear end 40b of the door beam 40, and an insertion hole (engaged portion) 70 provided in the lower end 17a of the center pillar 17 to engage with the engagement hook 60 (into which the engagement hook 60 is inserted), and is positioned so that when the front door 14A is closed, the rear end 40b of the door beam 40, the engagement hook 60 of the catcher mechanism 50, and the insertion hole 70 overlap each other when viewed from the vehicle width direction.

[0035] In addition, the engagement hook 60 of the catcher mechanism 50 has a protrusion 62 (first protrusion 62a and second protrusion 62b) that protrudes from the rear end 40b of the door beam 40 toward the inside in the vehicle width direction, and the insertion hole 70 is a hole that opens toward the outside in the vehicle width direction, and the protrusion 62 is inserted into the insertion hole 70 to engage.

[0036] According to the catcher structure of this embodiment, when a load due to a collision from the side of the vehicle (side impact) is input to the door beam 40, the door beam 40 is displaced inward in the vehicle width direction (toward the passenger compartment) due to the load, and the engaging hook 60 (protrusion 62) is displaced in a direction to be pushed (inserted deeper) into the insertion hole 70, thereby reducing the risk of the protrusion 62 of the engaging hook 60 coming out of the insertion hole 70. This makes it possible, with a simple configuration, to effectively prevent the catcher mechanism 50 from disengaging during a side impact of the vehicle. Therefore, a tensile force in the longitudinal direction can be more reliably applied to the door beam 40, effectively preventing the door beam 40 from deflecting inward in the vehicle width direction (toward the passenger compartment) due to the load of the side impact.

[0037] In the catcher structure of this embodiment, the protruding portion 62 of the engaging hook 60 is elongated such that its longitudinal direction L1 extends in a direction intersecting with the longitudinal direction L2 of the door beam 40.

[0038] According to this configuration, when the load caused by a side collision of the vehicle causes the longitudinal central portion of the door beam 40 to deform so as to be pushed closer to the passenger compartment than the both end portions 40a, 40b, and the protrusion 62 of the engaging hook 60 is displaced toward the longitudinal central portion of the door beam 40, the surface of the protrusion 62 of the engaging hook 60 (the front surface of the first protrusion 62a) comes into planar contact (so-called face contact) with the inner surface 70a (see FIG. 5) of the insertion hole 70 on the door beam 40 side, thereby more effectively preventing the protrusion 62 of the engaging hook 60 from slipping out of the insertion hole 70. That is, the protrusion 62 of the engaging hook 60 has an elongated shape in which the longitudinal direction L1 extends in a direction intersecting the longitudinal direction L2 of the door beam 40, and therefore the surface of the protrusion 62 comes into planar contact with the inner surface 70a of the insertion hole 70, thereby improving the contact resistance (friction resistance) of the contact portion between the protrusion 62 and the insertion hole 70. Furthermore, since the load acting on the contact portion between the protrusion 62 and the insertion hole 70 can be effectively distributed and received, the catcher mechanism 50 can be more effectively prevented from coming out of engagement even when a large load is applied.

[0039] Moreover, the catcher structure of this embodiment includes a bracket 80 for attaching the rear end portion 40b of the door beam 40 to the inner panel 20, and the engaging hook 60 is fixed to the bracket 80.

[0040] According to this configuration, the engaging hook 60 is fixed to the rear end portion 40b of the door beam 40 via the bracket 80, thereby preventing relative displacement between the door beam 40 and the engaging hook 60. Therefore, a tensile force can be more reliably applied to the door beam 40 in its longitudinal direction, which more effectively prevents the central portion of the door beam 40 in the longitudinal direction from being displaced (deformed) inward in the vehicle width direction (toward the passenger compartment).

[0041] Furthermore, according to this configuration, the engagement hook 60 is fixed to the rear end 40b of the door beam 40 via the bracket 80 made of a plate-shaped member that is relatively easy to process, which simplifies the manufacturing process of the vehicle (car body), improves manufacturing efficiency, and reduces costs compared to when the engagement hook 60 is directly fixed to the rear end 40b of the door beam 40.

[0042] In addition, in the catcher structure of this embodiment, the bracket 80 has a pair of extension portions 82, 82 extending in the longitudinal direction L2 of the door beam 40 on the upper and lower sides (on both sides in a direction intersecting the longitudinal direction L2 of the door beam 40) of the rear end portion 40b of the door beam 40, and the engagement hook 60 is fixed to this pair of extension portions 82, 82 of the bracket 80.

[0043] According to this configuration, the engaging hook 60 is fixed to the extension portions 82, 82 of the bracket 80 provided on both sides (upper and lower sides) of the rear end portion 40b of the door beam 40, thereby preventing the engaging hook 60 from moving in a direction that would cause it to fall on both sides (upper and lower sides) of the door beam 40 in a direction that intersects with the longitudinal direction in the event of a side collision of the vehicle.

[0044] In addition, in the catcher structure of this embodiment, the engagement hook 60 is composed of a first member 60A made of a plate-like member with a substantially L-shaped cross section, which has a first mounting portion (mounting surface) 61a attached to the front door 14A and a first protruding portion (insertion portion) 62a extending from the first mounting portion 61a toward the inside in the vehicle width direction (toward the passenger compartment), and a second member 60B made of a plate-like member with a substantially L-shaped cross section, which has a second mounting portion (mounting surface) 61b attached to the front door 14A and a second protruding portion (insertion portion) 62b extending from the second mounting portion 61b toward the inside in the vehicle width direction (toward the passenger compartment), and the first protruding portion 62a of the first member 60A and the second protruding portion 62b of the second member 60B are overlapped with each other, and the first mounting portion 61a of the first member 60A and the second mounting portion 61b of the second member 60B extend in different directions from each other.

[0045] According to this configuration, the first member 60A and the second member 60B that constitute the engagement hook 60 can be formed by bending, thereby improving the productivity of the vehicle body. Furthermore, by overlapping the first protruding portion 62a and the second protruding portion 62b and extending the first mounting portion 61a and the second mounting portion 61b in mutually different directions, it is possible to prevent the first protruding portion 62a and the second protruding portion 62b from tipping over (displacement of the first member 60A and the second member 60B in the direction in which the first protruding portion 62a and the second protruding portion 62b tilt), and therefore it is possible to more reliably prevent disengagement between the protruding portion 62 of the engagement hook 60 and the insertion hole 70.

[0046] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and various modifications are possible within the scope of the claims and the technical concept described in the specification and drawings. For example, in the above embodiments, the catcher structure of the present invention is applied to the front door 14A, but the catcher structure of the present invention can also be applied to the rear door 14B or other doors.
