Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a front end structure of a vehicle and a vehicle. Background Art

[0002] As consumers have higher and higher requirements for car styling, the front of new energy vehicles is getting shorter and shorter, which is called short front overhang in engineering, resulting in less and less space left in the front cabin for the powertrain. In vehicles with many and large powertrain components in the front cabin, the gap between the powertrain and the front panel of the vehicle will become smaller.

[0003] During a vehicle collision, there is a risk that the powertrain will move backwards. Since a high-voltage wire harness is provided in the gap between the powertrain and the front panel, the powertrain is likely to press the high-voltage wire harness against the master brake cylinder during movement, which may damage the high-voltage wire harness and cause a high-voltage risk. In the prior art, after a vehicle is hit, the high-voltage wire harness is cut off to avoid the high-voltage risk, but this cannot fundamentally avoid the powertrain from squeezing the high-voltage wire harness.

[0012] In some specific embodiments, the longitudinal beam is extended along the length direction of the vehicle, and a weakened groove is provided on the side wall of the longitudinal beam close to the inner side of the vehicle, and the weakened groove is recessed toward the outer side of the vehicle.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

[0031] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] In a first aspect, the present application provides a front end structure 10 of a vehicle. The front end structure 10 of the vehicle may be a front end structure of a new energy vehicle. Figure 1 It is a structural schematic diagram of an embodiment of a front end structure 10 of a vehicle provided in the present application.

[0033] Combination Figure 1 The front end structure 10 of the vehicle includes a front panel 11 and a power assembly 13. The power assembly 13 is arranged on one side of the front panel 11 close to the front of the vehicle in the length direction of the vehicle. The power assembly 13 is fixed to the longitudinal beam 12 of the vehicle and is spaced apart from the front panel 11.

[0034] Specifically, the dash panel 11 can be extended in both the vehicle width direction and the vehicle height direction, and the dash panel 11 can separate the front cabin of the vehicle from the passenger compartment. A hollow area can be formed between the dash panel 11 and the longitudinal beam 12, and the power assembly 13 is arranged at the hollow area to achieve fixed assembly. When the power assembly 13 and the dash panel 11 are arranged at intervals, a gap 14 is formed between the power assembly 13 and the dash panel 11 in the vehicle length direction. For the specific structure of the power assembly 13, the power assembly 13 can include an engine, a generator, and a drive motor, etc. At this time, the volume of the power assembly 13 is large, resulting in a small spacing between the gap 14 formed between the power assembly 13 and the dash panel 11 in the vehicle length direction. Due to the small spacing of the gap 14, when the vehicle is hit and the power assembly 13 moves backward in the vehicle length direction, the power assembly 13 is more likely to squeeze the high-voltage wire harness 16.

[0035] Continue to combine Figure 1The front end structure 10 of the vehicle further includes a brake master cylinder 15 and a high-voltage wire harness 16. The brake master cylinder 15 is protruded toward the front of the vehicle compared to the front panel 11, and at least part of the brake master cylinder 15 is located between the front panel 11 and the power assembly 13. The high-voltage wire harness 16 is connected to the power assembly 13, and part of the wire harness section of the high-voltage wire harness 16 is located in the gap 14 between the power assembly 13 and the front panel 11.

[0036] Specifically, the master brake cylinder 15 is used to provide brake pressure during the braking process of the vehicle. The master brake cylinder 15 can be raised in all or in part relative to the front panel 11. Based on this arrangement of the master brake cylinder 15, the distance between the master brake cylinder 15 and the power assembly 13 is smaller than the distance between the front panel 11 and the power assembly 13. In addition to being connected to the power assembly 13, the high-voltage wire harness 16 can also be connected to structures such as a battery pack to achieve power transmission. The high-voltage wire harness 16 can be a relatively long wire harness, and the portion of the wire harness segment located in the gap 14 between the power assembly 13 and the front panel 11 may be a relatively small portion of the wire harness segment.

[0037] Continue to combine Figure 1 The front end structure 10 of the vehicle further includes a guide mechanism 17, which is disposed on the side of the front panel 11 close to the front of the vehicle in the longitudinal direction of the vehicle. The guide mechanism 17 is provided with a guide slope on the side facing the powertrain 13, and an angle is formed between the guide slope and the longitudinal direction of the vehicle. The guide mechanism 17 may be a plate-shaped structure, a strip-shaped structure, etc., which is not specifically limited here. The guide slope may be a plane having an angle with the longitudinal direction of the vehicle. Of course, in other embodiments, the guide slope may also be an arc-shaped surface.

[0038] Specifically, the guide slope is arranged at intervals between the power assembly 13, and the guide slope can be arranged opposite to the rear structure of the power assembly 13 in the vehicle length direction. Based on the setting of the guide slope, the power assembly 13 can slide on the guide slope during the movement toward the rear of the vehicle, that is, when the power assembly 13 moves to abut against the guide slope, if the power assembly 13 moves further, it will slide on the guide slope. When the power assembly 13 slides on the guide slope, it will move in the vehicle width direction, that is, it can move in the vehicle length direction and width direction at the same time. It should be understood that at this time, it is mainly the rear part of the power assembly 13 that moves in the vehicle width direction. By moving the power assembly 13 in the vehicle width direction, the part of the high-voltage wire harness 16 located in the gap 14 and the brake master cylinder 15 in the vehicle width direction generates a gap 14 or the gap 14 increases. If the brake master cylinder 15 overlaps with the high-voltage wire harness 16 in the vehicle length direction, the movement of the power assembly 13 causes the brake master cylinder 15 and the high-voltage wire harness 16 to generate a gap 14 in the vehicle width direction. If the master brake cylinder 15 and the high-voltage wire harness 16 do not overlap in the vehicle length direction, there is a gap 14 between the master brake cylinder 15 and the high-voltage wire harness 16 in the vehicle width direction, and the gap 14 between the master brake cylinder 15 and the high-voltage wire harness 16 is further increased by the movement of the powertrain 13.

[0039] Figure 2 is a moving schematic diagram of the power assembly 13, Figure 3 is another moving schematic diagram of the power assembly 13 .

[0040] Combination Figure 2 as well as Figure 3 The power assembly 13 is connected to the longitudinal beam 12 through the suspension 18, and then the shock absorption can be achieved through the suspension 18. Among them, the suspension 18 can be provided on both the left and right sides of the power assembly 13, and then the suspension 18 is respectively connected to the left and right longitudinal beams 12.

[0041] After the vehicle is hit, especially when the front of the vehicle is hit, the powertrain 13 will move backward in the length direction of the vehicle. At this time, the longitudinal beam 12 of the vehicle will be deformed, and the suspension 18 will also change its relative position with respect to the powertrain 13. Figure 2 In some application scenarios, although the longitudinal beam 12 is deformed, the suspension 18 will not fall off from the powertrain 13. Figure 3 In other application scenarios, after the longitudinal beam 12 is deformed, the suspension 18 will fall off from the power assembly 13. However, no matter which method is used, the power assembly 13 will eventually contact the guide slope and then slide on the guide slope.

[0042] Figure 4 yes Figure 1 The structure shown is a schematic diagram of the power assembly 13 in the first moving state, Figure 5 yes Figure 1 The structure shown is a schematic diagram when the power assembly 13 is in the second moving state.

[0043] Combination Figure 4 , Figure 4 The power assembly 13 shown in the figure abuts against the guide slope and can slide on the guide slope. After further movement, the power assembly 13 slides on the guide slope and moves in the length direction and width direction of the vehicle at the same time, and finally moves to Figure 5 Position shown. Combined Figure 5 At this time, the high-voltage wire harness 16 is arranged in the gap 14 and the brake master cylinder 15 in the vehicle width direction. Although the rear of the power assembly 13 abuts against the brake master cylinder 15, the high-voltage wire harness 16 does not press against the brake master cylinder 15. Figure 4 The movement of the positions shown, and the Figure 4 Move the position shown to Figure 5 The movement modes of the positions shown can all be rotational movement modes, specifically counterclockwise rotation modes.

[0044] In summary, through the setting of the guide mechanism 17 and the guide slope, when the vehicle is hit and the power assembly 13 moves backward in the length direction of the vehicle, the guide slope can make the power assembly 13 move in the width direction of the vehicle, thereby causing a gap or an increase in the gap between the portion of the high-voltage wire harness 16 located in the gap 14 and the master brake cylinder 15 in the width direction of the vehicle. Therefore, even if the power assembly 13 collides with the brake assembly at this time, the high-voltage wire harness 16 is not between the master brake cylinder 15 and the power assembly 13, and the power assembly 13 will not squeeze the high-voltage wire harness 16 to cause damage to the high-voltage wire harness 16, and will not cause high voltage danger.

[0045] Continue to combine Figure 1 In some specific embodiments, the portion of the high-voltage wire harness 16 located in the gap 14 extends in the vehicle width direction in a direction away from the brake master cylinder 15, and the guide mechanism 17 is disposed on the side of the brake master cylinder 15 in the vehicle width direction away from the extension direction of the high-voltage wire harness 16. At this time, when the power assembly 13 slides on the guide slope, the high-voltage wire harness 16 will move in the vehicle width direction away from the guide mechanism 17.

[0046] Combination Figure 1, the portion of the high-voltage wire harness 16 located in the gap 14 extends to the left in the vehicle width direction, and the guide mechanism 17 is arranged on the right side of the brake master cylinder 15 in the vehicle width direction. At this time, if the power assembly 13 slides on the guide slope, the high-voltage wire harness 16 can move in the direction toward the left. Of course, the accompanying drawings only exemplarily show that the high-voltage wire harness 16 extends to the left side of the brake master cylinder 15, and the guide mechanism 17 is located on the right side of the brake master cylinder 15, which can be the opposite in other embodiments. It should be understood that through this arrangement, since the guide mechanism 17 is arranged on the side away from the extension direction of the high-voltage wire harness 16, when the power assembly 13 slides on the guide slope, the high-voltage wire harness 16 can move in the extension direction of the high-voltage wire harness 16, thereby avoiding the high-voltage wire harness 16 from being pulled and damaged.

[0047] Regarding the specific arrangement of the high-voltage wire harness 16, in some specific embodiments, the high-voltage wire harness 16 includes a first wire harness segment and a second wire harness segment connected to each other, the first wire harness segment is located on the top of the power assembly 13, and a portion of the second wire harness segment is located in the gap 14. The second wire harness segment overlaps with the brake master cylinder 15 in the vehicle width direction, or the spacing in the vehicle width direction is less than the preset spacing.

[0048] Specifically, one end of the first harness segment is connected to the powertrain 13, the other end of the first harness segment is connected to one end of the second harness segment, and the other end of the second harness segment is connected to the battery pack. Among them, the second harness segment is not fully displayed, and the high-voltage harness 16 located in the gap 14 is part of the second harness segment. When the part of the second harness segment located in the gap 14 overlaps with the brake master cylinder 15 in the vehicle width direction, it can be partially overlapped with the brake master cylinder 15, or it can be completely overlapped with the brake master cylinder 15. It should be understood that when the second harness segment overlaps with the brake master cylinder 15 in the vehicle width direction, when the powertrain 13 moves backward, the powertrain 13 is easy to squeeze the high-voltage harness 16. When the spacing between the second harness segment and the brake master cylinder 15 in the vehicle width direction is less than the preset spacing, it is not easy for the powertrain 13 to squeeze the high-voltage harness 16 when it moves backward, but there is still a certain risk of squeezing.

[0049] Regarding the specific arrangement of the guide mechanism 17, in some specific embodiments, the guide mechanism 17 is connected to the front panel 11 and the longitudinal beam 12 respectively, and the guide slope is directly opposite to the corner of the power assembly 13 near the rear side in the vehicle length direction, so that the corner of the power assembly 13 can slide on the guide slope. Figure 1At this time, the guide mechanism 17 can be specifically arranged at the corner position of the hollow area formed by the front wall panel 11 and the longitudinal beam 12, so as to avoid the arrangement of the guide mechanism 17 affecting the arrangement of other structures. The guide slope is directly opposite to the corner of the power assembly 13 near the rear side in the vehicle length direction, so that the corner of the power assembly 13 can slide on the guide slope, and the rear part of the power assembly 13 can move in the vehicle width direction through its corner, so that the rear part can move well in the vehicle width direction, so that the high-voltage wire harness 16 can move fully.

[0050] Figure 6 It is a structural schematic diagram of an embodiment of the guide mechanism 17 provided in the present application.

[0051] Combination Figure 6 The guide mechanism 17 may include a straight portion 171, the two ends of which are respectively fixed to the front panel 11 and the longitudinal beam 12, so that the straight portion 171, the front panel 11 and the longitudinal beam 12 enclose a hollow area, and a guide slope is formed on one side of the straight portion 171 close to the power assembly 13. Figure 1 At this time, the hollow area formed by the straight portion 171, the front wall plate 11 and the longitudinal beam 12 is roughly triangular in top view. Among them, the straight portion 171 can be arranged in a strip shape or a plate shape, which can be arranged according to the specific application scenario.

[0052] More specifically, the guide mechanism 17 further includes a first fitting portion 172 and a second fitting portion 173, the first fitting portion 172 and the second fitting portion 173 are respectively arranged at the two ends of the straight portion 171, the first fitting portion 172 is used to fit and fix to the front panel 11, and the second fitting portion 173 is used to fit and fix to the longitudinal beam 12. Among them, the straight portion 171, the first fitting portion 172 and the second fitting portion 173 can be integrally formed to ensure the stability of the structure. The first fitting portion 172 and the second fitting portion 173 can form an angle with the straight portion 171, so that the guide mechanism 17 is generally arranged in the shape of an arch bridge.

[0053] Figure 7 It is a diagram showing the angle formed by the straight portion 171 of the guide mechanism 17 in the length direction of the vehicle.

[0054] In some specific embodiments, the angle between the straight portion 171 and the vehicle length direction is smaller than a preset angle, and the distance between the straight portion 171 and the angled portion in the vehicle length direction is smaller than the distance between the powertrain 13 and the master brake cylinder 15 in the vehicle length direction. Figure 7 , the included angle between the straight portion 171 and the length direction of the vehicle is a, and at this time a is less than the preset angle. The preset angle may be 60°.

[0055] It should be understood that by setting the angle between the straight portion 171 and the vehicle length direction to be smaller than the preset angle, the guide slope is tilted sufficiently, thereby facilitating the reduction of the resistance generated by the sliding of the power assembly 13 on the guide slope, and facilitating the movement of the power assembly 13. By setting the spacing between the straight portion 171 and the corner portion in the vehicle length direction to be smaller than the spacing between the power assembly 13 and the brake master cylinder 15 in the vehicle length direction, the power assembly 13 will first hit the guide slope instead of the brake master cylinder 15 during the backward movement, thereby enabling the power assembly 13 to slide on the guide slope.

[0056] Figure 8 is a structural schematic diagram of an embodiment of the longitudinal beam 12 provided in the present application, Fig. 9 It is a structural schematic diagram of another embodiment of the longitudinal beam 12 provided in the present application.

[0057] Combination Figure 8 as well as Fig. 9 In some specific embodiments, the longitudinal beam 12 is extended along the length direction of the vehicle, and a weakened groove 121 is provided on the side wall of the longitudinal beam 12 close to the vehicle interior, and the weakened groove 121 is recessed toward the vehicle exterior. It should be understood that the power assembly 13 is located on the side of the longitudinal beam 12 close to the vehicle interior, and the weakened groove 121 is provided so that the longitudinal beam 12 can bulge toward the vehicle exterior during deformation, thereby facilitating the power assembly 13 to slide on the guide slope, such as Figure 2 , 3 shown.

[0058] Specifically, the weakened groove 121 may be a strip-shaped groove. In this case, the weakened groove 121 may extend along the height direction of the longitudinal beam 12. Figure 8 In some application scenarios, the length of the strip-shaped weakened groove 121 may be equal to the height of the longitudinal beam 12. Alternatively, the weakened groove 121 is a circular groove, and the weakened groove 121 is arranged at the bottom of the longitudinal beam 12, as shown in FIG. Fig. 9 In order to ensure the effect of the weakening groove 121 , a plurality of weakening grooves 121 may be provided on the longitudinal beam 12 .

[0059] The second aspect of the present application provides a vehicle, which includes a front end structure 10 of the vehicle in any of the above embodiments. For the specific description of the front end structure 10 of the vehicle, please refer to the content of the above embodiments, which will not be repeated here.

[0060] In summary, the front end structure 10 of the vehicle and the vehicle provided by the present application include: a front panel 11; a power assembly 13, which is arranged on the side of the front panel 11 close to the front of the vehicle in the length direction of the vehicle, and the power assembly 13 is fixed to the longitudinal beam 12 of the vehicle and is spaced apart from the front panel 11; a brake master cylinder 15, which is protruded in the direction toward the front of the vehicle compared to the front panel 11, and at least part of the brake master cylinder 15 is located between the front panel 11 and the power assembly 13; a high-voltage wire harness 16, which is connected to the power assembly 13, and part of the wire harness section of the high-voltage wire harness 16 is located between the power assembly 13 and The guide mechanism 17 is arranged on the side of the front panel 11 close to the front of the vehicle in the length direction of the vehicle, and a guide slope is arranged on the side of the guide mechanism 17 facing the power assembly 13, and an angle is formed between the guide slope and the length direction of the vehicle; wherein, the power assembly 13 can slide on the guide slope during the movement toward the rear of the vehicle, so that the power assembly 13 moves in the width direction of the vehicle, so that a gap 14 is generated between the part of the high-voltage wiring harness 16 located in the gap 14 and the master brake cylinder 15 in the width direction of the vehicle or the gap 14 is increased.

[0061] Therefore, based on any of the above embodiments, based on the setting of the guide mechanism 17, the power assembly 13 will move in the vehicle width direction during the backward movement, thereby causing a gap 14 to be generated between the high-voltage wire harness 16 and the master brake cylinder 15 or the gap 14 to increase, thereby preventing the power assembly 13 from pressing the high-voltage wire harness 16 against the master brake cylinder 15, thereby causing damage to the high-voltage wire harness 16 and causing a high voltage hazard.

[0062] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the scheme of the present application, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present application.
