Description

Technical Field

[0001] The present invention relates to a protective structure. Background Art

[0002] In recent years, as electric vehicles have become more common, hybrid vehicles, electric vehicles, and the like may have an inverter unit installed on the front of the vehicle to convert a DC voltage into an AC voltage in order to drive the electric motor.

[0003] For example, the inverter generates a high voltage required for the vehicle to run, and when the vehicle is deformed or disconnected due to a head-on collision or the like, a sudden abnormal reaction may occur.

[0004] Therefore, when a vehicle crashes, a structure is required to reduce the impact on devices requiring high voltage, such as an inverter and an air compressor.

[0005] As a technology for addressing the above-mentioned issues, the following technology is disclosed: the gap between the air compressor as an auxiliary machine and the bracket is narrowest near the upper mounting portion, so that when the vehicle collides with the front, the upper mounting portion with lower rigidity will be deformed, and the air compressor will rotate relative to the bracket with the lower mounting portion with higher rigidity as a fulcrum; by making the bracket and the air compressor abut at the narrowest part of the gap between the air compressor and the bracket, the air compressor can be properly suppressed from falling off due to the impact during a frontal collision of the vehicle (for example, refer to patent document 1).

[0040] Use below Figures 1 to 3 The configuration of the protection structure 1 according to the present embodiment will be described.

[0041] <About the front structure S>

[0042] In vehicle V, if Figure 1 As shown, a vehicle body front structure S is formed on the vehicle front side of a cabin CA as a vehicle interior in which passengers ride. The vehicle body front structure S is provided on the vehicle front side of the footrest portion TB. The vehicle body front structure S includes a frame portion FL and a drive portion DA.

[0043] (About the frame FL)

[0044] Frame part FL Figure 1 As shown in the dotted part of , in the vehicle body front structure S, they are connected in a cross-shaped pattern in the vehicle width direction and the vehicle front-rear direction. The frame part FL is the skeleton of the vehicle V and is composed of a strong metal having a substantially rectangular closed cross-sectional shape.

[0045] When a collision occurs, the frame portion FL protects the cabin CA and the drive unit DA by absorbing and dispersing the impact generated by the collision.

[0046] (About the drive unit DA)

[0047] The driving portion DA is disposed in the region of the vehicle body front structure S and is surrounded by the footrest portion TB and the frame portion FL.

[0048] The drive unit DA includes, for example, a power unit having an internal combustion engine driving the front wheels FT or a vehicle driving electric motor in an electric vehicle, and is a drive device provided with a transmission, a clutch, a drive shaft, and the like.

[0049] The driving portion DA is firmly fixed to the frame portion FL.

[0050] <About protection structure 1>

[0051] The protection structure 1 is a structure applied to a device constituting a driving portion DA that drives the front wheels FT of a vehicle V, for example.

[0052] like Figure 2(a) to Figure 2(c) As shown, the protection structure 1 includes a base 10, a lower bracket 100 as a first bracket, a front bracket 200 as a second bracket, and a sub-bracket SB.

[0053] In the driving portion DA, an adjacent component AD is disposed adjacent to the front bracket 200 on the front side of the protection structure 1. The adjacent component AD is, for example, an oil filter or an oil cooler.

[0054] The adjacent component AD is an object that collides with the protective structure 1 when the vehicle V collides.

[0055] Inside the protection structure 1 , an air compressor 20 as a protection target component, such as a device requiring a high voltage, is fixed to the base 10 via a front bracket 200 and a sub-bracket SB.

[0056] Specifically, for example, a front bracket 200 is provided at the front side of the protection structure 1 of the air compressor 20, and a sub-bracket SB is provided at the rear side of the protection structure 1 of the air compressor 20. A pedestal 21 and a pedestal 22 are formed at the upper and lower sides of the air compressor 20.

[0057] The air compressor 20 is fixed by bolts or the like via the pedestals 21 and 22 while being sandwiched between the front bracket 200 and the sub-bracket SB in the front-rear direction of the protection structure 1. The air compressor 20 is fixed to the base 10 via the front bracket 200 and the sub-bracket SB.

[0058] (Regarding base 10)

[0059] The base 10 is, for example, an internal combustion engine provided in the driving unit DA, and when a collision occurs, the impact caused by the collision is dispersed to the frame FL. The base 10 is firmly fixed to the frame FL.

[0060] (About Sub-Bracket SB)

[0061] The sub-bracket SB is provided on the rear side of the protection structure 1 of the air compressor 20 , sandwiches the air compressor 20 between the front bracket 200 and the sub-bracket SB, and fixes the air compressor 20 in the front-rear direction of the protection structure 1 by bolts or the like.

[0062] On the rear side of the protection structure 1 , the sub-bracket SB is fixed to the base 10 via the lower bracket 100 by means of bolts or the like.

[0063] The sub-bracket SB is a casting formed of a strong member such as metal.

[0064] (About the lower bracket 100)

[0065] A lower bracket 100 as a first bracket is fixed to the base 10 .

[0066] The lower bracket 100 is a casting formed of a solid member such as metal, for example.

[0067] As shown in Fig. 2(c), the lower bracket 100 is placed on the upper side of the base 10 and is arranged to cover the lower side of the air compressor 20. The front side of the lower bracket 100 in the protective structure 1 is bent along the base 10 into a substantially L shape.

[0068] The lower bracket 100 is fixed to the base 10 by bolts or the like.

[0069] A plurality of bolt holes penetrating from the upper side to the lower side are provided on the upper side of the lower bracket 100 , and as shown in FIG. 2( a ), the lower bracket 100 is fixed to the base 10 by bolts B11 to B13 .

[0070] The lower bracket 100 is provided with a plurality of bolt holes penetrating from the front side to the rear side of the protective structure 1 on the front side of the protective structure 1 , and is fixed to the base 10 by bolts B14 to B15 as shown in FIG. 2( b ).

[0071] The lower bracket 100 is provided with a plurality of bolt holes for the front bracket 200 and the sub-bracket SB to be fixed to the base 10 by bolts or the like.

[0072] (About the front bracket 200)

[0073] The front bracket 200 as the second bracket fixes and supports the air compressor 20 as the protection target component, and is fixed to the base 10 through the lower bracket 100 .

[0074] The front bracket 200 is formed of a casting made of a solid member such as metal, etc. The front bracket 200 is disposed on the front side of the protective structure 1 of the air compressor 20 and is provided to cover the air compressor 20 in the up-down and left-right directions.

[0075] The front bracket 200 is provided with a plurality of bolt holes penetrating from the front side to the rear side of the protection structure 1 for fixing the air compressor 20. In the front bracket 200, bolts BA1 to BA3 penetrate the base 21 and the base 22 to sandwich and fix the air compressor 20 between the front bracket 200 and the sub-bracket SB.

[0076] The front bracket 200 is provided with a plurality of bolt holes penetrating from the front side to the rear side of the protection structure 1. As shown in FIG2(b), the front bracket 200 penetrates the lower bracket 100 through bolts B21 to B23 and is fixed to the base 10. The front bracket 200 is fixed to the base 10 in surface contact with the lower bracket 100.

[0077] The bolts B21 to B23 that fix the front bracket 200 to the base 10 face in a direction different from the bolts B11 to B13 that fix the lower bracket 100 to the base 10. Specifically, for example, the bolts B21 to B23 are arranged from the front side to the rear side of the protective structure 1, and the bolts B11 to B13 are arranged from the upper side to the lower side as shown in FIG. 2(c).

[0078] like Figure 3 As shown, the front bracket 200 is formed with a contact portion 210 that protrudes toward an adjacent component AD disposed adjacent to the front bracket 200 .

[0079] The contact portion 210 is formed integrally with the front bracket 200 by a strong member such as metal.

[0080] The contact part 210 extends vertically at the left end and bends rightward below the bolt BA3 when viewed from the front of the protection structure 1. The contact part 210 has a reinforcing rib extending vertically on the right side of the bolt B23 and between the bolts BA2 and BA3.

[0081] like Figure 3 As shown in the shaded area of ​​, the contact portion 210 forms a contact surface SF at the front end of the protection structure 1. The contact surface SF is formed in a coplanar shape.

[0082] The bolts B21 to B23 that fix the front bracket 200 face a direction perpendicular to the abutment surface SF. Specifically, the abutment surface SF is formed into a plane shape in the up-down and left-right directions when viewed from the front side of the protection structure 1. The bolts B21 to B23 fix the front bracket 200 in the front-back direction of the protection structure 1. Therefore, the bolts B21 to B23 face a direction perpendicular to the abutment surface SF.

[0083] The rear side of the abutting portion 210 is provided with an overlapping portion OR where at least a portion of the abutting portion 210 and the lower bracket 100 overlap when viewed from the front side of the protection structure 1. Specifically, for example, at the overlapping portion OR, Figure 3 As shown by the thick two-dot chain line, the front bracket 200 and the lower bracket 100 are in surface contact with each other at the rear side of the abutment portion 210. In addition, the front bracket 200, the lower bracket 100 and the base 10 are firmly fixed by bolts B14 to B15 and bolts B21 to B23.

[0084] In the overlapping part OR Figure 3 In the range shown by the cross-hatched portion, the lower bracket 100 is disposed on the rear side of the abutment portion 210 in the protective structure 1 in an overlapping manner.

[0085] <Function and Effect>

[0086] use Figure 4 In the protective structure 1 of the present embodiment constructed as above, a collision occurs to the vehicle V, for example, the adjacent component AD Figure 4 The effect when a collision occurs in the direction indicated by arrow AR1 in (a) will be described.

[0087] When the vehicle V collides, the adjacent component AD collides in the direction indicated by the arrow AR1. Figure 4 The energy is transmitted in the direction indicated by the arrow AR1 in (a).

[0088] The adjacent component AD collides with the abutment portion 210 in the front bracket 200. The collision energy is as follows: Figure 4 As shown in (b) of FIG. 1 , the light is dispersed in the directions indicated by arrows AR2 , AR3 , and AR4 and is transmitted to the rear side of the protective structure 1 .

[0089] The collision energy in the direction of arrow AR2 is transferred from the front bracket 200 to the sub-bracket SB in the directions indicated by arrows AR5 and AR6 through the pedestals 21 and 22. The collision energy transferred to the sub-bracket SB is transferred to the base 10 in the direction indicated by arrow AR7 through the lower bracket 100 in the direction indicated by arrow AR8 and absorbed.

[0090] The collision energy in the direction of arrow AR3 is transmitted to the upper side of the lower bracket 100 through the front bracket 200. Then, the collision energy is transmitted to the base 10 through the bolts B11 to B13 fixing the upper side of the lower bracket 100 and the base 10, and the bolts BS1 to BS2 fixing the sub-bracket SB, the lower bracket 100 and the base 10.

[0091] The bolts B21 to B23 fixing the front bracket 200 to the base 10 face in a direction different from the bolts B11 to B13 fixing the down bracket 100 to the base 10. Furthermore, the bolts BA1 to BA3 fixing the front bracket 200 to the sub-bracket SB face in a direction different from the bolts BS1 to BS2 fixing the sub-bracket SB to the base 10.

[0092] Specifically, for example, bolts B11 to B13 and bolts BS1 to BS2 are fixed to the base 10 from the upper side to the lower side. The collision energy transmitted to the upper side surface of the lower bracket 100 is transmitted to the base 10 through the bolts B11 to B13 and bolts BS1 to BS2. Therefore, the collision energy is dispersed from the direction indicated by the arrow AR3 to the direction indicated by the arrow AR8 or the arrow AR10 and transmitted to the base 10.

[0093] Furthermore, the front bracket 200 , the front side surface of the lower bracket 100 and the base 10 are in close contact with each other, and the movement of the upper side surface of the lower bracket 100 toward the rear side is restricted.

[0094] Therefore, the collision energy applied to the bolts B11 to B13 and BS1 to BS2 fixing the lower bracket 100 to the base 10 toward the rear side of the protection structure 1 is limited.

[0095] The collision energy in the direction of arrow AR4 is transmitted through the front side of the front bracket 200 in the protective structure 1 to the front side of the lower bracket 100 in the protective structure 1 and to the base 10 .

[0096] The bolts B21 to B23 that fix the front bracket 200 face in a direction orthogonal to the abutment surface SF. Specifically, the bolts B21 to B23 fix the front bracket 200 in a linear shape in the direction protruding from the abutment portion 210. Therefore, the collision energy transmitted from the abutment portion 210 is effectively transmitted to the base 10 in a linear shape in the direction of the arrow AR4 through the bolts B21 to B23.

[0097] Part of the collision energy in the direction of arrow AR4 is transmitted to the base 10 in the direction indicated by arrow AR9 at the lower side of the lower bracket 100 fixed to the base 10 by bolts B14 and B15 .

[0098] The collision energy in the directions of arrows AR3 and AR4 is transmitted through the overlapping portion OR where the abutting portion 210 of the front bracket 200 and the lower bracket 100 overlap.

[0099] At the overlapping portion OR, the front bracket 200, the lower bracket 100 and the base 10 are in surface contact with each other on the front side of the protection structure 1 and are firmly fixed by bolts B21 to B23. The lower bracket 100 and the base 10 are further firmly fixed by bolts B14 to B15.

[0100] Bolts B21 to B23 and bolts B14 to B15 are fixed to the lower bracket 100 and the base 10 from the front side to the rear side of the protection structure 1. The collision energy transmitted to the front bracket 200 is transmitted to the base 10 through the bolts B21 to B23 and bolts B14 to B15.

[0101] Furthermore, since the front bracket 200 , the under bracket 100 , and the base 10 are in surface contact, the collision energy transmitted to the contact portion 210 is transmitted to the under bracket 100 and the base 10 in the directions of arrows AR3 and AR4 .

[0102] Therefore, at the overlapping region OR, the collision energy transmitted to the contact portion 210 is efficiently transmitted to the base portion 10 in a linear shape, and is absorbed by the base portion 10 and the frame portion FL.

[0103] Furthermore, when the collision energy is transferred from the adjacent component AD, as Figure 4 As shown in (c), the collision energy is transmitted to the rear side of the protective structure 1 while deforming the abutment portion 210 and the front bracket 200. The lower bracket 100 and the base 10 are compressed in the directions of arrows AR3 and AR4, so that the collision energy is absorbed.

[0104] The collision energy transmitted to the abutment portion 210 is further dispersed to the lower bracket 100 and the sub-bracket SB through the bolts B21 to B23 and the bolts BA1 to BA3 that fix the front bracket 200. The collision energy transmitted to the lower bracket 100 is further dispersed to the base 10 through the bolts B11 to B15. The collision energy transmitted to the sub-bracket SB is further dispersed to the lower bracket 100 and the base 10 through the bolts BS1 to BS2.

[0105] Then, the collision energy is transmitted to the base portion 10 while being dispersed in the directions indicated by arrows AR2 to AR10 .

[0106] The collision energy transmitted to the base portion 10 is transmitted in the direction indicated by the arrow AR11 and is absorbed by the frame portion FL.

[0107] Then, the protective structure 1 stops the movement of the adjacent component AD, and the transfer of the collision energy ends.

[0108] As described above, when the vehicle V collides, for example, when the adjacent component AD collides with the protective structure 1, the abutment portion 210 receives the collision energy, and the protective structure 1 transfers the collision energy to the base 10 while dispersing the collision energy to the base 21, base 23, sub-bracket SB and lower bracket 100 of the air compressor 20.

[0109] Then, the protective structure 1 transmits the collision energy to the base 10 while dispersing the collision energy, thereby allowing the base 10 to absorb the collision energy without causing the air compressor 20 as the protection target component to be interfered with by the adjacent components AD.

[0110] As described above, the protective structure 1 of the present embodiment includes a frame portion FL constituting a skeleton of the vehicle V, a base portion 10 that disperses the impact caused by the collision to the frame portion FL when a collision occurs, a lower bracket 100 as a first bracket fixed to the base portion 10, and a front bracket 200 as a second bracket, the front bracket 200 fixing and supporting the air compressor 20 as a protection target component to be protected in the impact caused by the collision, and being fixed to the lower bracket 100 and fixed to the base portion 10 through the lower bracket 100. The front bracket 200 is formed with an abutment portion 210 that protrudes toward the adjacent component AD disposed adjacent to the front bracket 200, and the abutment portion 210 is overlapped with at least a portion of the lower bracket 100 at an overlap portion OR when viewed from the side from which the abutment portion 210 protrudes.

[0111] That is, when the vehicle V collides, for example, when the adjacent component AD hits the protective structure 1, the collision energy is transmitted to the abutment portion 210 provided on the front bracket 200. The protective structure 1 transmits the collision energy transmitted from the abutment portion 210 to the front bracket 200 to the base 10 while dispersing the collision energy to the bolts B11 to B15 fixing the lower bracket 100 and the base 10 and the bolts B21 to B23 fixing the front bracket 200 and the lower bracket 100. Furthermore, at the overlapping portion OR, the front bracket 200 provided with the abutment portion 210 is in surface contact with the base 10 through the lower bracket 10, and the front bracket 200, the lower bracket 100 and the base 10 are firmly fixed by the bolts. Then, at the overlapping portion OR, the collision energy transmitted to the abutment portion 210 is effectively transmitted to the base 10 in a linear shape and absorbed by the base 10 and the frame portion FL.

[0112] Therefore, the protective structure 1 can transfer the collision energy from the front bracket 200 provided with the abutment portion 210 to the base 10 by dispersing the collision energy through the bolts B11 to B15 and the bolts B21 to B23 that fix the lower bracket 100 to the base 10. The collision energy transferred to the front bracket 200 can be effectively transferred to the base 10 at the overlapping portion OR.

[0113] The protection structure 1 transmits the collision energy to the base 10 while dispersing the collision energy, and the collision energy is dispersed and absorbed by the base 10 and the frame portion FL, thereby preventing the adjacent components AD from interfering with the air compressor 20 as the protection target component.

[0114] Therefore, when a vehicle collides, interference with devices that need to be protected can be effectively prevented.

[0115] In the protection structure 1 of the present embodiment, the fixing direction of the front bracket 200 to the lower bracket 100 is oriented in a direction perpendicular to the abutment surface SF formed by the abutment portion 210 protruding therefrom.

[0116] That is, the collision energy transmitted to the abutting portion 210 is transmitted to the front side of the lower bracket 100 through the front side of the front bracket 200 , and is thus transmitted to the base 10 .

[0117] The bolts B21 to B23 that fix the front bracket 200 face in a direction perpendicular to the contact surface SF. Specifically, the bolts B21 to B23 fix the front bracket 200 in a linear shape in a direction protruding toward the contact portion 210 .

[0118] Therefore, the collision energy received by the contact surface SF formed by the abutment portion 210 can be efficiently transmitted to the base portion 10 in a linear shape in the direction of the arrow AR4 through the bolts B21 to B23.

[0119] Therefore, when a vehicle collides, interference with devices that need to be protected can be effectively prevented.

[0120] In the protection structure 1 of the present embodiment, at least a portion of the fixing direction of the lower bracket 100 to the base 10 is oriented in a direction different from the direction in which the front bracket 200 is fixed to the lower bracket 100 .

[0121] That is, the bolts B21 to B23 and BS1 to BS2 that fix the front bracket 200 to the base 10 face in a direction different from the bolts B11 to B13 that fix the lower bracket 100 to the base 10. Specifically, for example, the bolts B11 to B13 and the bolts BS1 to BS2 are fixed to the base 10 from the upper side to the lower side. Then, the collision energy transmitted to the upper side of the lower bracket 100 is transmitted to the base 10 through the bolts B11 to B13 and the bolts BS1 to BS2. Then, the collision energy is converted from the direction from the front side to the rear side of the protective structure 1 to the direction from the upper side to the lower side and transmitted to the base 10.

[0122] Therefore, the protective structure 1 converts the direction of the collision energy transmitted from the front bracket 200 to the lower bracket 100 and transmits it to the base 10, whereby the protective structure 1 can limit the collision energy transmitted to the base 10. Thereafter, the base 10 can effectively absorb the collision energy.

[0123] Therefore, when a vehicle collides, interference with devices that need to be protected can be effectively prevented.

[0124] The embodiments of the present invention have been described in detail above with reference to the drawings, but the specific configuration is not limited to the embodiments, and designs that do not depart from the scope of the present invention are also included in the present invention.
