Description

Technical Field

[0001] This invention relates to a front structure of a vehicle, for example, equipped with high-voltage components such as an electric compressor. Background Technology

[0002] Electric vehicles, driven by electric motors, or hybrid vehicles combining a drive engine and an electric motor, have traditionally used electric compressors that can operate independently of engine drive to compress the refrigerant for air conditioning. For example, in the vehicle described in Patent Document 1, an electric compressor is installed in the frame portion of the front area of ​​the vehicle near the driver's seat.

[0003] As described above, the electric compressor has a live part through which high-voltage current flows inside the casing, and a high-voltage wiring harness that connects the power control unit and other components to the live part is connected to the outer periphery of the casing. To protect these live parts and wiring harness connections, for example, as described in Patent Document 1, after fixing the electric compressor to the rear side of the engine in the vehicle, the front side of the electric compressor can be protected by the engine.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2020-82789. Summary of the Invention

[0007] The technical problem that the invention aims to solve

[0008] For example, when an electric compressor is located at the front of the engine of a vehicle due to constraints such as component layout, it is necessary to cover the front of the electric compressor with a protective component to protect the electric compressor from impact loads applied at the front of the vehicle.

[0009] However, if the structure of the electric compressor is simply covered with protective components, the protective components will obstruct the connection of the high-voltage wiring harness to the electric compressor housing during vehicle assembly or removal of the high-voltage wiring harness from the electric compressor housing during maintenance, resulting in low operating efficiency.

[0010] It can be said that the same applies when high-voltage components other than electric compressors, such as electric water pumps, are installed in the front area of ​​the vehicle.

[0011] In view of the above, the present invention aims to provide a front structure of a vehicle that is easy to operate when installing and removing high-voltage wiring harnesses relative to high-voltage components located in the front region of a vehicle, and can reliably protect the live parts and wiring harness connections when impact loads are applied from the front of the vehicle.

[0012] Technical means to solve technical problems

[0013] To achieve the above objective, in the technical solution of the present invention, when an impact load is applied from the front side of the vehicle, a portion of the protective member bends toward the rear side of the vehicle to cover the connection portion of the high-voltage wiring harness in the high-voltage component.

[0014] That is, the front structure of the vehicle according to the first embodiment includes: a high-voltage component, fixed to the front side of a fixed part disposed in the front region of the vehicle, and having an energized part inside that is energized during operation; a protective member, protecting the high-voltage component; wherein, a wire harness connection portion for connecting a high-voltage wire harness is provided on the outer peripheral region of any one of the two sides in the vehicle width direction, the upper side of the vehicle, and the lower side of the vehicle in the high-voltage component; the protective member includes: a first cover portion, covering the area corresponding to the energized part from the front side of the vehicle; a second cover portion, continuously disposed with the first cover portion, located at a certain interval from the wire harness connection portion towards the front side of the vehicle, and covering the wire harness connection portion from the front side of the vehicle; and a low-rigidity portion, disposed in the portion where the first cover portion and the second cover portion are continuous, having a lower rigidity than the first cover portion and the second cover portion.

[0015] The second embodiment relates to a front structure of a vehicle, comprising: a high-voltage component, which is fixed to the front side of the vehicle by a fixed part disposed relative to the front region of the vehicle and has an energized part inside that is energized during operation; a protective member that protects the high-voltage component; wherein a wiring harness connection part for connecting a high-voltage wiring harness is provided on the outer periphery of any one of the two sides in the vehicle width direction, the upper side of the vehicle, and the lower side of the vehicle; the protective member comprises: a first cover part that covers the area corresponding to the energized part from the front side of the vehicle; a second cover part that is continuously disposed with the first cover part and is located at a certain interval from the wiring harness connection part towards the front side of the vehicle, covering the wiring harness connection part from the front side of the vehicle; and a low-rigidity part disposed at the portion where the first cover part and the second cover part are continuous, which becomes the starting point of bending deformation at least when an impact load is applied to the second cover part from the front side of the vehicle, wherein the bending deformation is such that the second cover part bends relative to the first cover part towards the rear of the vehicle so that the second cover part is positioned to cover the wiring harness connection part.

[0016] The front structure of the vehicle according to the third embodiment, in the first or second embodiment, is composed of one or more grooves or holes, and one or more continuous portions connecting the first cover portion and the second cover portion.

[0017] The fourth embodiment relates to a front structure of a vehicle in which, in the third embodiment, the wiring harness connection portion is provided on the outer peripheral region of either side of the high-voltage component in the vehicle width direction; the protective member is provided on a ridge portion extending in the vehicle width direction; and at least one of the groove recess or hole portion is formed at a position across the ridge portion.

[0018] The fifth embodiment relates to a front structure of a vehicle. In the first or second embodiment, the wiring harness connection portion is located on the outer periphery of either side of the high-voltage component in the vehicle width direction. The protective member includes: a third cover portion extending from the upper part of the first cover portion toward the rear of the vehicle and covering the area corresponding to the energized part from the upper side; and a fourth cover portion extending from the lower part of the first cover portion toward the rear of the vehicle and covering the area corresponding to the energized part from the lower side.

[0019] The sixth embodiment relates to a front structure of a vehicle in which, in the fifth embodiment, the third and fourth covers are not integrally formed with the first cover.

[0020] The seventh embodiment relates to a front structure of a vehicle, in the fifth embodiment, wherein at least one of the third and fourth covers is provided with a protruding shape portion that extends toward the upper or lower side of the vehicle and extends in the longitudinal direction of the vehicle.

[0021] Invention Effects

[0022] In the first and second embodiments, a space is provided between the second cover and the wiring harness connection, allowing the operator to easily install and remove the high-voltage wiring harness relative to the high-voltage component during assembly or maintenance. On the other hand, after the protective member is subjected to an impact load from the front of the vehicle, the high-voltage component fixed to the fixed part will hinder the first cover from moving towards the rear of the vehicle. Therefore, the first cover is maintained in a state where it covers the area corresponding to the live part of the high-voltage component from the front of the vehicle. Furthermore, since a space is provided at the rear of the vehicle for the second cover, the second cover moves towards the rear of the vehicle while bending relative to the first cover from a low-rigidity point, eventually covering the area corresponding to the wiring harness connection of the high-voltage component. In this way, the protective member covers the live part and wiring harness connection while approaching the live part of the high-voltage component, thus preventing the live part and wiring harness connection from becoming exposed and effectively protecting them.

[0023] In the third embodiment, the low-rigidity part can be formed through relatively easy processing, thus keeping the processing cost very low.

[0024] In the fourth embodiment, when the second cover is bent and deformed relative to the first cover toward the rear of the vehicle, the impact load can be efficiently transferred from the ridge portion to the low-rigidity portion, and a stable bending deformation can be induced with the low-rigidity portion as the entry point. Therefore, when an impact load is applied to the protective member from the front of the vehicle, the second cover can be prevented from deforming in an unexpected direction relative to the first cover, and the wiring harness connection portion can be reliably covered by the second cover.

[0025] In the fifth embodiment, the upper side of the area corresponding to the live part of the high-voltage component can be protected by the third cover, and the lower side of the area corresponding to the live part of the high-voltage component can be protected by the fourth cover. Therefore, the high-voltage component can be reliably protected even if an impact load is applied to it from the upper or lower side of the vehicle.

[0026] In the sixth embodiment, the complex-shaped protective member that covers the area corresponding to the live part of the high-voltage component from three sides—the front side, the upper side, and the lower side of the vehicle—is easier to manufacture. Therefore, the amount of machining work can be reduced, and the manufacturing cost can be kept very low.

[0027] In the seventh embodiment, due to the protruding shape portion extending in the vehicle's longitudinal direction, the section modulus of the section intersecting the vehicle's longitudinal direction in the third or fourth cover portion becomes larger. Therefore, the third or fourth cover portion is less likely to deform relative to the first cover portion in the vehicle's vertical direction, preventing abnormal noises or reduced durability caused by repeated up-and-down vibrations of the third or fourth cover portion.

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. Furthermore, the following description of preferred embodiments is merely illustrative in nature.

[0040] Figure 1 This indicates the front structure 10 of a vehicle 1 according to an embodiment of the present invention. This vehicle 1 is a hybrid vehicle that operates via a so-called hybrid system. An engine compartment R1 (front region of the vehicle) housing the engine E (fixed part) constituting the hybrid system is located approximately at the center of the front structure 10. Furthermore, in this description, the front side of the vehicle is simply referred to as "front," the rear side as "rear," the right side as "right," and the left side as "left."

[0041] A front bulkhead 10a is provided on the rear side of the engine compartment R1 to separate the engine compartment R1 from the cabin R2. Front hinge pillars 10b supporting the front door (not shown) and enabling it to rotate are provided on the left and right sides of the front bulkhead 10a.

[0042] In the upper part of the engine compartment R1, a pair of skirt members 10c, which are slowly curved and extend forward from each front hinge pillar 10b in a manner that approaches each other, are provided on the left and right sides at certain intervals. On the upper front side of the engine compartment R1, there is a roughly U-shaped cover member 10d that is wide in the vehicle width direction when viewed from above, and each end is connected to the front end of each skirt member 10c.

[0043] On the other hand, in the upper and lower middle part of the engine compartment R1, a pair of front side frames 10e with a cross-section of rectangular shape that extends in a roughly straight line from front to back are provided on the left and right sides at certain intervals. At the front end of each front side frame 10e, a square cylindrical energy-absorbing box 10g with the center line of the cylinder facing the front and back direction is connected by a flange portion 10f.

[0044] In addition, a bumper reinforcement 10h that extends in the vehicle width direction and whose central part is located in front of the upper and lower middle part of the engine compartment R1 is provided. The front end of the energy absorption box 10g is connected to the rear side of the left and right ends of the bumper reinforcement 10h.

[0045] A generally rectangular resin shield S with thickness is disposed between the bumper reinforcement 10h and the engine E. The shield S is positioned with its thickness along the longitudinal direction of the vehicle, and its upper edge is connected to the shield upper component 10d.

[0046] like Figure 2 and Figure 3 As shown, an electric compressor 2 (high-voltage component) for compressing air conditioning refrigerant is installed at the right end of the lower front part of engine E.

[0047] like Figures 3 to 7 As shown, the electric compressor 2 is a roughly cylindrical shape with its centerline extending along the width of the vehicle. From the central part inside to the left end, there is a live part 2a including a motor that is energized during operation, an inverter device, etc.

[0048] A wiring harness connection portion 2b protrudes from the upper part of the left outer peripheral region of the electric compressor 2, and a connector portion 3a of a high-voltage wiring harness 3 connected to a power control unit (not shown) is connected to the wiring harness connection portion 2b.

[0049] In addition, high voltage in this specification refers to DC voltage exceeding 60 volts or AC voltage exceeding 30 volts (RMS), and high voltage components broadly refer to electrical components that operate under such voltages.

[0050] A protective component 4 is provided on the front side of the electric compressor 2 to protect the electric compressor 2.

[0051] The protective component 4 is roughly U-shaped and opens to the rear when viewed in the vehicle width direction, and includes: a front protective plate 5, located in front of the electric compressor 2; an upper protective plate 6 and a lower protective plate 7, which are not integrally formed with the front protective plate 5, and are located on the upper and lower sides of the electric compressor 2, respectively.

[0052] The front protective plate 5 is made by pressing steel plates, such as... Figure 3As shown, the upper and lower central regions extend forward in an arc shape when viewed in the vehicle width direction. In the front protective plate 5, the ridge portion 5a, which extends in the vehicle width direction and is formed by bending during the pressing process, is formed in three places at certain intervals in the upper and lower parts, thereby improving the surface rigidity.

[0053] The area from the center of the front protective plate 5 in the vehicle width direction to the right end constitutes the first covering portion 8 of the present invention, and the left side area continuous with the first covering portion 8 of the front protective plate 5 constitutes the second covering portion 9 of the present invention.

[0054] like Figures 4 to 6 As shown, the first cover 8 covers the area corresponding to the charged part 2a of the electric compressor 2 from the front.

[0055] The upper region of the first cover 8 is shaped to extend further upward than the second cover 9, and is fastened to the engine E together with the electric compressor 2 at the right side position by a fastening member B.

[0056] The lower region of the first cover 8 extends further downward than the second cover 9. It is fixed to the engine E by two fastening members B together with the electric compressor 2 at the right and left positions that are separated in the vehicle width direction.

[0057] like Figure 3 As shown, a support plate 8a made of steel is installed on the upper right side of the front side of the first cover 8. The support plate 8a extends in a generally wavy shape when viewed from the vehicle width direction and supports a cooler hose (not shown).

[0058] In addition, such as Figure 4 As shown, an interference avoidance hole 8b is formed on the upper left side of the first cover portion 8, with the upper region being shorter than the lower region in the vehicle width direction. The drain valve 2c of the electric compressor 2 faces forward through this interference avoidance hole 8b.

[0059] like Figure 5 As shown, the second covering part 9 is located at a certain interval from the front side of the wire harness connecting part 2b, and covers the wire harness connecting part 2b from the front side.

[0060] A first groove recess 5b (grooving recess) that opens upward is formed at the upper end of the portion where the first cover portion 8 and the second cover portion 9 are continuous, and a second groove recess 5c (grooving recess) that opens downward is formed at the lower end of the portion where the first cover portion 8 and the second cover portion 9 are continuous.

[0061] Between the first groove recess 5b and the second groove recess 5c in the continuous part of the first cover portion 8 and the second cover portion 9, the first elongated hole 5d (hole portion) and the second elongated hole 5e (hole portion) are arranged in order from top to bottom, passing through each other and extending vertically. The first elongated hole 5d is located across the two ridge portions 5a on the upper side.

[0062] A first groove recess 5b, a second groove recess 5c, a first elongated hole 5d, and a second elongated hole 5e are provided in the continuous portion of the first covering portion 8 and the second covering portion 9, thereby providing three continuous portions 5f that connect the first covering portion 8 and the second covering portion 9 between the first groove recess 5b and the first elongated hole 5d, between the first elongated hole 5d and the second elongated hole 5e, and between the second groove recess 5c and the second elongated hole 5e.

[0063] Then, the first groove recess 5b, the second groove recess 5c, the first elongated hole 5d, the second elongated hole 5e, and the continuous portion 5f constitute the low-rigidity portion 11 of the present invention. This low-rigidity portion 11 is located at approximately the same position as the left end of the electric compressor 2 in the vehicle width direction, and its rigidity is lower than that of the first cover portion 8 and the second cover portion 9. Thus, as... Figures 8 to 11 As shown, at least when the impact load L1 is applied to the second cover 9 from the front, the second cover 9 is bent and deformed rearward relative to the first cover 8, starting from the low rigidity part 11, so that the second cover 9 becomes the position covering the wire harness connection part 2b.

[0064] like Figure 5 and Figure 7 As shown, the upper protective plate 6 is formed by pressing a steel plate into an L-shaped cross section, including a third covering portion 6a that is roughly rectangular when viewed from above, and a flange portion 6b that extends downward from the front edge of the third covering portion 6a.

[0065] The upper protective plate 6 is spot-welded to the upper part of the first cover part 8 via the flange 6b and assembled onto the front protective plate 5. The third cover part 6a extends from the upper part of the first cover part 8 to the rear side and covers the area corresponding to the live part 2a from the upper side.

[0066] Furthermore, a first protruding shape portion 6c is formed on the front side of the left end of the third cover portion 6a, which is generally semi-circular and extends upward from the front-rear direction of the vehicle and extends in the front-rear direction of the vehicle.

[0067] The lower protective plate 7 is obtained by pressing steel plates, such as... Figure 6 and Figure 7 As shown, it includes a fourth covering portion 7a that is roughly platform-shaped when viewed from above, and a pair of extending portions 7b that extend downward from two points on the front side edge of the fourth covering portion 7a.

[0068] The lower protective plate 7 is assembled to the front protective plate 5 by spot welding a pair of extensions 7b to the lower part of the first cover 8. The fourth cover 7a extends from the lower part of the first cover 8 to the rear and covers the area corresponding to the live part 2a from the lower side.

[0069] Furthermore, the left side region of the fourth covering portion 7a extends downward in a stepped manner compared to the right side region, forming the second protruding shape portion 7c of the present invention.

[0070] Next, the actions around the electric compressor 2 in the front structure 10 when the traveling vehicle 1 collides with obstacle A located on the right front will be described in detail. Furthermore, Figures 8 to 11 For ease of explanation, only the operation of the main structure of the front structure 10 under the applied collision load L is described.

[0071] like Figure 8 and Figure 9 As shown, after vehicle 1 traveling in the X direction collides with obstacle A from the front, the impact load L is first applied from the front to the right side region of bumper reinforcement 10h. Then, bumper reinforcement 10h moves while shifting to the left and deforming rearward. After bumper reinforcement 10h begins to move, the energy-absorbing box 10g on the right side collapses in the longitudinal direction, and the front region of the right front side frame 10e also begins to shift to the left while deforming. Then, the rear space of bumper reinforcement 10h narrows, and the shield S and its surrounding components begin to move rearward while being squeezed and collapsed.

[0072] The right side of the protective cover S, which is being squeezed and collapsed while moving backward, is located in front of the electric compressor 2, therefore... Figure 10 As shown, the shield S collides with the protective member 4 from the front, applying an impact load L1 to the protective member 4 from the front. After the protective member 4 is subjected to the impact load L1, the electric compressor 2 fixed to the engine E will prevent the first cover 8 of the protective member 4 from moving to the rear. Therefore, the first cover 8 is maintained in a state of covering the area corresponding to the charged part 2a of the electric compressor 2 from the front.

[0073] On the other hand, the second cover 9 of the protective member 4 has a certain space on the rear side, so that... Figure 10 and Figure 11 As shown, one side of the cover moves backward relative to the first cover 8, starting from the low-rigidity part 11, and becomes the position that covers the area corresponding to the wiring harness connection part 2b of the electric compressor 2.

[0074] In this way, according to an embodiment of the present invention, when an impact load L is applied from the front side to the front structure 10 of the vehicle 1, the protective member 4 covers the live part 2a and the wiring harness connection part 2b in a state close to the electric compressor 2, thereby preventing the live part 2a and the wiring harness connection part 2b from becoming exposed, and effectively protecting the live part 2a and the wiring harness connection part 2b.

[0075] On the other hand, under normal circumstances, a certain space is provided between the second cover 9 and the wire harness connection 2b, so that during assembly and maintenance operations, the operator can easily install and remove the high-voltage wire harness 3 relative to the electric compressor 2.

[0076] Furthermore, the low-rigidity portion 11 can be formed relatively easily at the point where the first cover portion 8 and the second cover portion 9 are continuous, such as the first groove recess 5b and the first elongated hole 5d. Therefore, the processing cost of the protective member 4 can be kept very low.

[0077] Furthermore, the first elongated hole 5d in the low-rigidity section 11 is formed at the position of the ridge section 5a extending in the vehicle width direction across the protective member 4. Therefore, when the second cover section 9 is bent and deformed rearward relative to the first cover section 8, the impact load L1 can be efficiently transmitted from the ridge section 5a to the low-rigidity section 11, and a bending deformation with the low-rigidity section 11 as the entry point can be stably induced. Therefore, when a collision load L1 is applied to the protective member 4 from the front, the second cover section 9 can be prevented from deforming in an unexpected direction relative to the first cover section 8, and the wiring harness connection section 2b can be reliably covered by the second cover section 9.

[0078] Furthermore, the third cover 6a can protect the upper side of the area corresponding to the live part 2a of the electric compressor 2, and the fourth cover 7a can protect the lower side of the area corresponding to the live part 2a of the electric compressor 2. Therefore, even if an impact load L is applied to the electric compressor 2 from the upper or lower side of the vehicle, the electric compressor 2 can be reliably protected.

[0079] Furthermore, the third cover portion 6a covering the upper side of the electric compressor 2 and the fourth cover portion 7a covering the lower side are not integrally formed with the first cover portion 8 covering the front side of the electric compressor 2. Therefore, it is relatively easy to manufacture a complex-shaped protective member 4 that covers the area corresponding to the live part 2a of the electric compressor 2 from the front, upper, and lower sides. As a result, the amount of processing work can be reduced, and the processing cost can be kept very low.

[0080] Furthermore, the third cover portion 6a has a first protruding shape portion 6c that extends upward and in the vehicle's longitudinal direction, and the fourth cover portion 7a has a second protruding shape portion 7c that extends downward and in the vehicle's longitudinal direction. Therefore, the section modulus of the section of the third cover portion 6a or the fourth cover portion 7a intersecting the vehicle's longitudinal direction is increased. Consequently, the third cover portion 6a or the fourth cover portion 7a is less likely to deform relative to the first cover portion 8 in the vehicle's vertical direction, preventing abnormal noise or reduced durability caused by repeated vertical vibrations.

[0081] Furthermore, in the front structure 10 according to the embodiments of the present invention, the operation of the second cover 9 when the shield S contacts the protective member 4 from the front and applies an impact load L1 to it is described, but when other parts such as the shield S contact the protective member 4 from the front, the second cover 9 also performs the same operation.

[0082] Furthermore, in embodiments of the present invention, the wiring harness connection portion 2b is provided in the left outer peripheral region of the electric compressor 2, but the front structure 10 of the present invention is also applicable when it is provided in the right outer peripheral region, upper outer peripheral region, or lower outer peripheral region of the electric compressor 2.

[0083] Furthermore, in embodiments of the present invention, the electric compressor 2 is fixed to the front side of the engine E, but is not limited thereto; for example, it may be a structure fixed to the front side of any frame part or component in the front region of the vehicle.

[0084] Furthermore, the low-rigidity portion 11 according to the embodiments of the present invention is composed of a first groove recess 5b, a second groove recess 5c, a first elongated hole 5d, a second elongated hole 5e, and a continuous portion 5f arranged in a row in the vertical direction. However, it is not necessary for them to be arranged in a row, as long as the second cover portion 9 bends rearward relative to the first cover portion 8 when an impact load L1 is applied. In addition, the low-rigidity portion 11 may be composed only of the first groove recess 5b and the second groove recess 5c, or it may be composed only of the first elongated hole 5d and the second elongated hole 5e. The first elongated hole 5d and the second elongated hole 5e may be other shapes, such as circular or polygonal. In particular, in order to make the rigidity of the continuous portion of the first cover portion 8 and the second cover portion 9 lower than that of the first cover portion 8 and the second cover portion 9, it is not necessary to provide a hole structure or a slot structure. For example, the thickness of the continuous portion of the first cover portion 8 and the second cover portion 9 can be made thinner than that of the first cover portion 8 and the second cover portion 9, thereby making it a low-rigidity structure.

[0085] Furthermore, in embodiments of the present invention, the first elongated hole 5d is formed at the position of the cross-ridge portion 5a, but it can also be a structure in which the first groove recess 5b, the second groove recess 5c, and the second elongated hole 5e are formed at the position of the cross-ridge portion 5a.

[0086] Furthermore, in embodiments of the present invention, the third covering portion 6a and the fourth covering portion 7a are not integrally formed with the first covering portion 8, but they can also be integrally formed.

[0087] Furthermore, in embodiments of the present invention, at the third covering portion 6a, the first protruding shape portion 6c is in an upward-extending shape, but it can also be in a downward-extending shape; at the fourth covering portion 7a, the second protruding shape portion 7c is in a downward-extending shape, but it can also be in an upward-extending shape. Moreover, it is not necessary for both the first protruding shape portion 6c of the third covering portion 6a and the second protruding shape portion 7c of the fourth covering portion 7a to be formed; forming at least one is sufficient.

[0088] Furthermore, the protective component 4 involved in the embodiments of the present invention protects the electric compressor 2, but it can also be applied to protect other high-voltage components, such as electric water pumps, electric oil pumps and other high-voltage components.
