Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle body structures, and in particular, to a vehicle front cabin structure and a vehicle. Background Art

[0002] The front cabin structure in the body structure is located at the front of the vehicle body, generally used to accommodate components such as engines and vacuum boosters. The water trough is generally arranged below the front windshield for draining rainwater along the water trough. The body structure near the water trough of this type of vehicle has weak dynamic stiffness in the left-right direction, which will cause the shock absorbers of the chassis to be prone to torsion and increased vibration when passing over uneven roads, thus bringing discomfort to the occupants. Moreover, due to insufficient dynamic stiffness, the body structure is more likely to be fatigued and damaged and torn. Summary of the Invention

Detailed description of the specific implementation

[0041] The following will describe in detail the specific implementation of the present disclosure in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0042] In the present disclosure, unless otherwise specified, the orientation terms such as "upper, lower, left, right, front, and back" generally refer to "upper, lower, left, and right" when the vehicle front cabin structure 100 is installed on the vehicle, which is consistent with the "upper, lower, left, and right" directions when the vehicle is driving normally. The X direction is the front-back direction, the Y direction is the left-right direction, and the Z direction is the up-down direction. "Inner and outer" refer to the inner and outer of the contours of relevant components. In addition, the terms "first", "second", etc. used in the embodiments of the present disclosure are used to distinguish one element from another and do not have sequentiality and importance.

[0043] In the related art, both ends of the water trough 10 are only connected to the wheel housing 42 and the shock absorber seat plate 41 through a small bracket. In such a structure, since there are few mounting and fixing connection points with the left and right wheel housings 42 and the seat plate, the Y-direction dynamic stiffness of the wheel housing of this type of vehicle is relatively weak.

[0044] In order to improve the Y-direction dynamic stiffness near the water trough 10, a vehicle front cabin structure 100 and a vehicle are provided in the present disclosure. As Figure 1-12 shown, the vehicle front cabin structure includes a water trough 10, two shock absorber seat plates 41, two upper side beams 20 arranged at intervals in the left-right direction, and two wheel housings 42 arranged at intervals in the left-right direction. The water trough 10 is connected between the two upper side beams 20. The shock absorber seat plates 41 and the wheel housings 42 correspond one by one. The top of each wheel housing 42 is provided with a shock absorber seat plate 41. The wheel housing 42 is connected to the inner side of the upper side beam 20. Both ends of the water trough 10 are respectively connected to the shock absorber seat plate 41, and both ends of the water trough 10 also extend to be connected to the upper side beam 20 and connected to the upper side beam 20.

[0045] Through the above technical solution, both ends of the water trough are connected to the upper side beam and the shock absorber seat plate 41 above the wheel housing, so as to support and connect the shock absorber seat plates 41, wheel housings 42 and upper side beams 20 on both sides, strengthening the Y-direction dynamic stiffness of the shock absorber, thereby greatly improving the overall vehicle life, driving mileage and occupant comfort. In addition, a complete force transmission path is formed, which helps to transmit the force on the wheel housing, etc. to the A-pillar on the vehicle body structure through the shock absorber seat plate 41, water trough 10 and upper side beam 20, contributing to the transmission and dispersion of force.

[0046] The vacuum booster is a component that uses vacuum (negative pressure) to increase the force applied by the driver to the pedal. The vacuum booster is generally located between the brake pedal and the brake master cylinder and is installed on the front bulkhead in the front cabin structure. The vacuum booster is a relatively easily damaged part on the vehicle and often needs to be repaired. When repairing the vacuum booster, it is usually disassembled and repaired from the chassis of the vehicle, which requires disassembling more parts and is not convenient for operation.

[0047] To facilitate the repair of the vacuum booster in the engine compartment 30, a vehicle front compartment structure 100 and a vehicle are provided in the present disclosure. As Figure 1-12 shown, the vehicle front compartment structure 100 includes a water trough 10 and two upper side beams 20 spaced apart in the left-right direction. The water trough 10 is connected between the two upper side beams 20. The water trough 10 includes a first water trough body 11 and a second water trough body 12 both extending in the left-right direction. The first water trough body 11 and the second water trough body 12 are detachably spliced in the front-rear direction of the vehicle, and the first water trough body 11 is located in front of the second water trough body 12. The second water trough body 12 is disposed adjacent to the front windshield. The vehicle front compartment structure 100 further includes an engine compartment 30 for accommodating the vacuum booster. The water trough 10 is disposed on the top of the engine compartment 30, and the first water trough body 11 is located on the top of the vacuum booster. The first water trough body 11 is detachably connected between the two upper side beams 20.

[0048] Through the above technical solution, since the first water trough body 11 is detachably connected between the two upper side beams 20, when parts such as the vacuum booster in the engine compartment 30 below the first water trough body 11 are damaged, the engine hood can be conveniently opened, the first water trough body 11 can be removed, and parts such as the vacuum booster in the engine compartment 30 can be repaired and replaced. Moreover, during the general assembly of the vehicle, it is also convenient to install the pipelines on the front bulkhead 52 through the operation space generated by the detachable first water trough body 11.

[0049] In an embodiment of the present disclosure, the first water trough body 11 is detachably connected between the two upper side beams 20, and both ends of the second water trough body 12 are fixedly connected between the two upper side beams 20. As Figure 1-2 shown in FIGS. 4-5, the vehicle front compartment structure 100 further includes two shock absorber seat plates 41 and two wheel housings 42 spaced apart in the left-right direction. The shock absorber seat plates 41 correspond to the wheel housings 42 one by one. A shock absorber seat plate 41 is disposed on the top of each wheel housing 42. The wheel housing 42 is connected to the inner side of the upper side beam 20, and both ends of the first water trough body 11 are detachably connected to the shock absorber seat plates 41 respectively, and both ends of the second water trough body 12 are fixedly connected to the shock absorber seat plates 41 respectively.

[0050] In the above technical solution of the present disclosure, the first water trough body 11 is installed by a detachable connection method such as bolt connection, which is convenient for the disassembly and assembly of the parts in the engine compartment 30. In addition, both ends of the second water trough are directly fixedly lapped on the shock absorber seat plates 41, so as to support and connect the shock absorber seat plates 41 and the wheel housings 42 on both sides, which helps to strengthen the Y-direction dynamic stiffness of the shock absorber, thereby greatly improving the vehicle life, driving mileage, and occupant comfort.

[0051] It can be understood that in other embodiments, both the first water trough body 11 and the second water trough body 12 are detachably connected between the two upper side beams 20.

[0052] In one embodiment of the present disclosure, in order to further enhance the Y-direction dynamic stiffness of the shock absorber, as Figure 1 and Figure 4 shown, the vehicle front cabin structure 100 further includes a glass cross beam 51 extending in the left-right direction. The front windshield of the vehicle is disposed above the glass cross beam 51. The upper side beam 20 extends in the front-rear direction of the vehicle. The rear side of the second water tank body 1 is fixedly connected to the glass cross beam 51. Both ends of the first water tank body 11 are detachably connected to the shock absorber seat plate 41, and both ends of the second water tank body 12 are connected to the shock absorber seat plate 41. Both ends of the first water tank body 11 and the second water tank body 12 continue to extend outward from the shock absorber seat plate 41 and extend to the upper side beam 20 and are connected to the upper side beam 20. Optionally, both ends of the first water tank body 11 can lean on the upper side beam 20, and both ends of the second water tank body 12 can abut against the upper side beam 20, so that the water chute 10, the glass cross beam 51, and the relatively arranged upper side beams 20 on both sides of the water chute 10 and the glass cross beam 51 together form a U-shaped support frame. The overall structure formed by the water chute 10 and the glass cross beam 51 is connected between the two spaced upper side beams 20, thereby forming a U-shaped support frame. Optionally, as Figure 11 shown, the rear end of the upper side beam 20 is connected to the A-pillar 201 of the vehicle.

[0053] On the one hand, the U-shaped support frame can significantly increase the Y-direction dynamic stiffness of the shock absorber and improve the comfort of the occupants. On the other hand, it increases the force transmission path during a collision. The force can be directly transmitted to the A-pillar 201 through the wheel housing 42 and the upper side beam 20, and the wheel housing 4 and the upper side beam 20 can also transmit the force to the A-pillar 201 on the other side through the water chute 10 and the glass cross beam 51, increasing the force transmission path and also dispersing the collision force received.

[0054] In one embodiment of the present disclosure, in order to increase the reliable connection between the water chute 10 and the shock absorber seat plate 41, as Figure 2 , 5 , 6 shown, both ends of the first water tank body 11 are provided with first overlapping portions 111. Optionally, the first overlapping portions 111 are formed into a semi-enclosed C-shaped structure or an L-shaped structure. The first overlapping portions 111 overlap on the shock absorber seat plate, and are matched with the outer contour shape of one side of the shock absorber seat plate 41. Both ends of the second water tank body 12 are provided with second overlapping portions 121. Optionally, the second overlapping portions 121 are formed into a semi-enclosed C-shaped structure or an L-shaped structure. The second overlapping portions 121 overlap on the shock absorber seat plate 41 and are matched with the outer contour shape of the other side of the shock absorber seat plate 41. The first overlapping portions 111 and the second overlapping portions 121 are oppositely arranged and surround the shock absorber seat plate 41 therebetween. The ends of the first overlapping portions 111 and the second overlapping portions 121 are connected to the inner side of the upper side beam 20.

[0055] By constructing the first overlapping part 111 and the second overlapping part 121 into a C-shaped structure or an L-shaped structure, the shock absorber seat plate 41 is surrounded, and the outer contour shapes of the first overlapping part 111 and the second overlapping part 121 are matched with that of the shock absorber seat plate 41. In this way, the contact area between the water chute 10 and the shock absorber seat plate 41 can be increased, which helps to increase the connection strength and is also convenient for transmitting the collision force.

[0056] To increase the strength of the water chute 10 itself, as Figure 2 and Figure 6-7 shown, the vehicle front cabin structure 100 further includes a glass cross beam 51 extending in the left-right direction. The vehicle front cabin structure 100 further includes a water chute reinforcing member 13, and the water chute reinforcing member 13 includes a connected first reinforcing part 131 and a second reinforcing part 132. The first reinforcing part 131 extends in the front-rear direction of the vehicle, and one end of the first reinforcing part 131 is connected to the first water chute body 11, and the other end is connected to the second reinforcing part 132. The bottom of the second reinforcing part 132 is connected to the second water chute body 12, and the side wall of the second reinforcing part 132 is connected to the glass cross beam 51. By providing the water chute reinforcing member 13, on the one hand, the water chute reinforcing member 13 is connected between the first water chute body 11 and the second water chute body 12, so that the connection strength between the first water chute body 11 and the second water chute body 12 can be increased. On the other hand, the water chute reinforcing member 13 is also connected between the water chute 10 and the glass cross beam 51, so that the overall strength of the water chute 10 can be increased, which is convenient for connecting and supporting the shock absorber seat plates 41 on both sides through the water chute 10 and increasing the Y-direction dynamic stiffness of the shock absorber.

[0057] Optionally, in order to facilitate the disassembly of the first water chute body 11, one end of the first reinforcing part 131 is detachably connected to the first water chute body 11, and the other end is detachably connected to the second reinforcing part 132. For example, the detachable connection can be achieved by screws, etc. The first reinforcing part 131 is generally configured as a strip structure, the second reinforcing part 132 is generally configured as a sheet structure, and a weight-reducing hole is also provided on the second reinforcing part 132.

[0058] In one implementation manner, as Figure 2 shown, a plurality of water chute reinforcing members 13 are arranged at intervals in the left-right direction of the water chute 10.

[0059] To prevent the water in the water chute 10 from flowing into the engine compartment 30, as Figure 6As shown in the figure, the cross-section of the first water tank body 11 is an L-shaped structure and includes a first bottom plate 112 and a first side plate 113. The cross-section of the second water tank body 12 is an L-shaped structure and includes a second bottom plate 122 and a second side plate 123. The first side plate 113 and the second side plate 123 are arranged opposite to each other, and the first bottom plate 112 and the second bottom plate 122 are detachably spliced in the front-rear direction of the vehicle, so that the cross-section of the water chute 10 (the cross-section along the front-rear direction of the vehicle) is configured into a U-shaped structure. Optionally, the edges of the first bottom plate 112 and the second bottom plate 122 are partially overlapped in the front-rear direction of the vehicle and are connected by bolts.

[0060] The erected first side plate 113 and the second side plate 123 can form a continuous vertical water retaining structure, which can effectively prevent the water in the water chute 10 from overflowing. Moreover, the erected first side plate 113 and the second side plate 123 can also drain the water to the first bottom plate 112 and the second bottom plate 122 for discharging through the drain port 14 below. Optionally, the edge of the second side plate 123 is turned outwards towards the water chute 10.

[0061] In order to prevent the water chute 10 formed by splicing the first water tank body 11 and the second water tank body 12 from leaking, in an embodiment of the present disclosure, as Figure 6 shown, the first bottom plate 112 and the second bottom plate 122 at least partially overlap each other, and the edges of the first bottom plate 112 and the second bottom plate 122 overlap together. A seal (not shown in the figure) is provided at the overlapping portion between the first bottom plate 112 and the second bottom plate 122. One end of the seal extends in the left-right direction of the vehicle to the shock absorber seat plate 41 and the upper side beam 20 on one side, and the other end of the seal extends in the left-right direction to the shock absorber seat plate 41 and the upper side beam 20 on the other side. Both ends of the seal are arranged at the overlapping portion between the shock absorber seat plate 41 and the water chute 10. The seal extends through the overlapping portion between the shock absorber seat plate 41 and the water chute 10 and continues to extend to the upper side beam 20. Seals are provided at all mating surfaces where the water chute 10 may leak, thereby increasing the sealing performance of the water chute 10 and effectively preventing the water in the water chute 10 from leaking.

[0062] In the present disclosure, there is no limitation on how to drain the accumulated water in the water chute 10. Optionally, in an embodiment, as Figure 1 、 2 、6 shown, a drain port 14 communicating with the outside is opened on the water chute 10 and faces the bottom of the vehicle.

[0063] In the related art, the drain outlet 14 faces the left and right directions of the vehicle, and is provided at the connection between the water trough 10 and the upper side beam 20, and the accumulated water is discharged through the drain outlet 14 provided at the upper side beam 20. However, opening a hole in the upper side beam 20 will affect the strength of the upper side beam 20. In the event of a collision, the upper side beam 20 is prone to deformation and intrusion. The existing automobile's water trough 10 flows water through the upper side beam inner plate with openings on the left and right sides, resulting in the need for separate welding of parts at the water hole of the upper side beam 20, which leads to higher requirements for the overlap sealing of the parts, and often the risk of repair due to leakage or seepage due to poor glue coating. Moreover, arranging the front charging port at this location will have the risk of leakage due to water erosion, and the waterproof and anti-leakage performance of the charging port is difficult to guarantee.

[0064] In the above-described embodiment of the present disclosure, since the drain outlet 14 faces the bottom of the vehicle, i.e., the Z-direction, the water in the trough 10 is discharged directly outside the vehicle. For example, the drain outlet 14 faces the wheel guard, discharging the water directly into the surrounding environment near the guard. This avoids the need for holes in the roof rail 20, ensuring the strength of the roof rail 20 and the integrity and load-bearing performance of the inner and outer panels of the roof rail 20. This allows the impact force during a frontal collision to be distributed from the front to the rear A-pillar 201, avoiding force transmission interruption caused by holes in the roof rail 20, which could lead to deformation and excessive intrusion of the engine compartment 30. Furthermore, this effectively addresses the waterproofing and leakage prevention issues associated with the placement of the charging port in the front fender 53. Furthermore, both sides of the trough 10 can be directly welded to the roof rail 20, eliminating the need for intermediate transitional connections. This ensures better connection precision and sealing requirements, better meets sealing and waterproofing requirements, and improves the vehicle's corrosion resistance.

[0065] In order to drain the drain outlet 14 in the water trough 10 as quickly as possible, Figure 6 As shown, at least two drain outlets 14 are provided on the water trough 10. The two drain outlets 14 are provided on the second water trough body 12 and are respectively arranged at both ends of the second water trough body 12. The first bottom plate 112 of the first water trough body 11 is located above the second bottom plate 122 of the second water trough body 12, so that the accumulated water in the first water trough body 11 will flow into the second water trough body 12. Optionally, the water trough 10 as a whole has a structure with a high middle and low sides in the left-right direction, and the drain outlet 14 is located at the lowest position of the second water trough body 12. The accumulated water in the water trough 10 will flow toward the drain outlets 14 at the left and right ends, and finally be discharged from the drain outlets 14.

[0066] In order to further enhance the strength of the front cabin structure near the water trough 10, in one embodiment of the present disclosure, Figure 5As shown, the vehicle front compartment structure 100 further includes a bulkhead 52, a first wheelhouse reinforcement 71, and two longitudinal beams 54 spaced apart in the vehicle width direction. The longitudinal beams 54 are disposed below the water trough 10. The wheelhouse 42 extends in the up-and-down direction. The upper part of the first wheelhouse reinforcement 71 is connected to the water trough 10, the lower part is connected to the longitudinal beam 54, the side part is connected to the wheelhouse 42, and the rear part is connected to the bulkhead 52. The first wheelhouse reinforcement 71 is supported on the bottom of the water trough 10.

[0067] By providing the first wheelhouse reinforcement 71, the longitudinal beam 54, the water trough 10, the wheelhouse 42, and the bulkhead 52 are connected together. On the one hand, the strength of the wheelhouse 42 and the water trough 10 can be significantly increased. On the other hand, since the outer side of the wheelhouse 42 is also connected to the upper side beam 20, the collision force borne by the longitudinal beam 54 can be transmitted to the water trough 10 and the wheelhouse 42 through the first wheelhouse reinforcement 71, and then transmitted to the upper side beam 20 and the A-pillar 201, increasing the dispersion path of the collision force, thereby improving the anti-collision performance of the front compartment structure.

[0068] Optionally, two first wheelhouse reinforcements 71 are provided in the front compartment structure of the present disclosure, which are respectively disposed on the left and right sides of the vehicle and are symmetrically arranged with respect to the central axis extending in the vehicle length direction.

[0069] In the present disclosure, the specific structure of the upper side beam 20 is not limited. In one embodiment of the present disclosure, the upper side beam 20 includes an upper side beam inner panel and an upper side beam outer panel, both of which extend in the vehicle front-rear direction. The upper side beam inner panel and the upper side beam outer panel are buckled with each other to form a cavity. A side beam reinforcement is disposed in the cavity of the upper side beam 20, and the side beam reinforcement fits against the inner wall of the cavity. The side beam reinforcement extends in the length direction of the upper side beam 20 and extends to the connection position between the upper side beam 20 and the wheelhouse 42.

[0070] The upper side beam 20 with a cavity structure has low weight, high strength, and good bending resistance. Moreover, by providing a side beam reinforcement in the cavity, the strength of the upper side beam 20 can be further enhanced, which helps the force on the longitudinal beam 54 to be transmitted to the vehicle body A-pillar 201 through the upper side beam 20. The longitudinal beam 54 and the vehicle body A-pillar 201 are the main components with relatively high strength at the front of the vehicle that can resist collisions. Ensuring the sufficient strength and force-bearing performance of the upper side beam 20 can disperse the collision force during a front collision from the front to the rear A-pillar 201, avoiding deformation and excessive intrusion of the engine compartment 30 due to insufficient strength of the upper side beam 20 resulting in interruption of force transmission.

[0071] In one embodiment of the present disclosure, as Figure 4As shown, a water retaining strip 21 is formed on the upper edge side inside the upper side beam 20. The water retaining strip 21 stands on the upper surface of the upper side beam 20 and extends in the front-rear direction. In the present disclosure, there is no limitation on how to form the above-mentioned water retaining strip 21. Optionally, the upper edge inside the upper side beam 20 can be flanged upward to form the above-mentioned water retaining strip 21. This water retaining strip 21 can prevent the water of the ventilation cover plate from flowing into the engine compartment. The water chute 10 extends to the water retaining strip 21, so as to form a water flow channel between the water retaining strip 21 and the water chute 10. The water retaining strip is a vertical welded facade, which can block the water flowing down from the water chute and the windshield to prevent it from flowing into the engine compartment.

[0072] To increase the overall strength of the front cabin structure, as Figure 11 shown, the vehicle front cabin structure 100 further includes two connecting members 73 and two longitudinal beams 54 arranged at intervals in the left-right direction. The longitudinal beams 54, the connecting members 73 and the upper side beam 20 correspond one by one. The rear end of the upper side beam 20 is used to connect with the A-pillar 201, and the front end of the upper side beam 20 is connected to the longitudinal beam 54 through the connecting member 73. Therefore, both ends of the upper side beam 20 can be respectively connected to the A-pillar 201 and the longitudinal beam 54, playing a role in strengthening the front-rear connection. Thus, a force transmission path from the longitudinal beam 54 to the A-pillar 201 can be established through the upper side beam 20, so as to transmit the collision force received by the longitudinal beam 54 during a frontal collision from the front to the rear A-pillar 201 for dispersion, reducing the possible deformation and intrusion amount of the engine compartment 30. Since the frontal collision force during a collision is not only transmitted through the longitudinal beam 54, but also a force transmission path that transmits the collision force to the A-pillar 201 through the upper side beam 20 and the wheelhouse 42 also exists synchronously, the deformation and intrusion amount of the longitudinal beam 54 can be smaller. For vehicles with a short front overhang and short longitudinal beam 54, the intrusion amount of the front bulkhead 52 of the engine compartment 30 being pushed by the motor or engine into the cockpit can be reduced, so that the front cabin structure in the present disclosure has a higher collision rating and the safety of the vehicle provided with this front cabin structure is better. On the other hand, since the wheelhouse 42 and the shock absorber seat plate 41 can also be connected to the longitudinal beam 54 through the upper side beam 20, therefore, the dynamic stiffness performance of the wheelhouse 42 and the shock absorber in the X, Y, and Z directions is further strengthened.

[0073] To increase the strength of the front cabin structure, as Figure 5 shown, the vehicle front cabin structure 100 further includes a second wheelhouse reinforcement 72. The side wall of the second wheelhouse reinforcement 72 is connected to the wheelhouse 42. One end of the second wheelhouse reinforcement 72 is connected to the connection part of the wheelhouse 42 and the upper side beam 20, and the other end is connected to the longitudinal beam 54, and the other end is arranged at an interval from the connecting member 73, so that the upper side beam 20, the longitudinal beam 54 and the second wheelhouse reinforcement 72 form a triangular support structure.

[0074] The triangular support structure has high strength and strong stability, thereby increasing the dynamic stiffness of the wheelhouse 42 and the front bulkhead 52, and being able to jointly withstand and disperse the collision force during a collision, enhancing the anti-collision performance of the front cabin structure.

[0075] As Figure 14 shown, the second wheelhouse reinforcement 72 includes a first wheelhouse reinforcement outer panel 721 and a second wheelhouse reinforcement inner panel 722. After the first wheelhouse reinforcement outer panel 721 and the second wheelhouse reinforcement inner panel 722 are welded, a hollow cavity structure is formed. The upper part of the hollow cavity structure is connected to the upper side beam 20, and the side part is connected to the wheelhouse 42 and the shock absorber seat plate 41.

[0076] Optionally, two second wheelhouse reinforcements 72 are provided in the front cabin structure of the present disclosure, respectively arranged on the left and right sides of the vehicle, symmetrically arranged with respect to the central axis extending in the length direction of the vehicle. Therefore, the above triangular support structure can be formed on both the left and right sides of the vehicle.

[0077] In order to increase the strength at the installation position of the brake pedal bracket 85, in an embodiment of the present disclosure, as Figure 8-10 shown, the vehicle front cabin structure 100 further includes a front bulkhead 52 connected between two upper side beams 20, a front cabin lower cross beam 82 extending in the left-right direction, an instrument pipe beam mounting reinforcement plate 81, and a booster mounting reinforcement plate 83. The front bulkhead 52 includes a pedal mounting portion 84 for mounting the brake pedal bracket 85. The pedal 202 is fixed to the brake pedal bracket 85. The booster mounting reinforcement plate 83 is disposed in contact with the pedal mounting portion 84, and the upper part of the booster mounting reinforcement plate 83 is connected to the instrument pipe beam mounting reinforcement plate 81, and the lower part is connected to the front cabin lower cross beam 82. The side part of the booster mounting reinforcement plate 83 passes through the front bulkhead 52 and is connected to the first wheelhouse reinforcement 71. The vacuum booster is mounted at the booster mounting reinforcement plate 83, below the water trough 10. Therefore, the first water tank body 11 can be removed to repair or replace the vacuum booster.

[0078] By arranging the booster mounting reinforcement plate 83 in this way, the stiffness requirement at the installation position of the brake pedal bracket 85 can be met, and the thickness of the booster mounting reinforcement plate 83 can be minimized as much as possible, with a smaller area, making the weight of the booster mounting reinforcement plate 83 lighter and the cost lower.

[0079] In the related art, in an electric vehicle or a hybrid vehicle, a power battery is used as a power source for a motor, and the motor is used to drive the wheels to run. The power battery is charged through a charging port on the vehicle body, and the power battery can be charged through a DC charging socket or an AC charging socket. However, when the DC charging socket and the AC charging socket are arranged at the same place, it will occupy a large space on the vehicle body. Therefore, on some vehicles, the DC charging socket and the AC charging socket are respectively arranged on the left and right sides of the vehicle body, but this will increase the total length of the high-voltage wiring harness. In addition, some vehicles integrate the DC charging socket and the AC charging socket into one body, and the integrated AC / DC charging port is arranged on the same side of the vehicle body. Moreover, in order to have a larger layout space, the charging port is usually arranged at the rear of the vehicle body. This will make the distance between the charging port and the power battery charging port in the engine compartment 30 located at the front of the vehicle body relatively far, and a longer high-voltage wiring harness is required for connection, and the wiring design is relatively complex.

[0080] To solve the above problems, as Figure 1 , 3 shown in FIGS. 11, the vehicle front compartment structure 100 in the present disclosure further includes a charging port seat 60 and a front fender 53. The charging port seat 60 includes a first charging port 61 for installing a DC charging socket and a second charging port 62 for installing an AC charging socket. The front fender 53 is disposed outside the upper side beam 20, and a recessed portion 24 is formed by the inward depression of the outer surface of the upper side beam 20 to form a charging port accommodation cavity between the front fender 53 and the recessed portion 24, and the charging port seat 60 is disposed in the charging port accommodation cavity.

[0081] Compared to conventional techniques that involve drilling a hole in the roof rail 20, the above-described technical solution minimizes the impact on the strength and stiffness of the roof rail 20 and its impact on its collision resistance by recessing the outer surface of the roof rail 20 inward to form a recessed portion 24 to accommodate the charging port holder 60. This minimizes the impact on the strength and stiffness of the roof rail 20 and its impact on its collision resistance, thereby ensuring collision force transmission through the roof rail 20 and the dynamic stiffness of the wheel arch 42 connected to the roof rail 20. Routing the charging port cable without passing through the hole in the roof rail 20 further ensures the integrity and load-bearing performance of the roof rail 20. Therefore, the roof rail 20 can disperse the collision force transmitted from the front to the rear A-pillar 201 during a frontal collision, avoiding deformation of the cabin 30 and excessive intrusion due to force transmission interruption caused by the hole in the roof rail 20. Moreover, both the AC and DC charging ports are arranged on the same charging port holder 60. On the one hand, it is convenient for users to perform charging operations. When parking, it is only necessary to ensure that the side where the charging port holder 60 is arranged is facing the charging pile. On the other hand, the AC and DC charging sockets are arranged in the same place and are arranged on the front cabin structure. Since the powertrain is also arranged in the front cabin 30, the length of the cable can be greatly shortened, which is also convenient for cable arrangement. The charging port is close to the grounding point, which is easy to operate and saves the cost of cables. In addition, the cables in the above scheme do not need to pass through the holes on the inner and outer plates of the upper side beam 20 during assembly like the traditional structure. Therefore, there is no risk of the sharp metal holes of the inner and outer plates of the upper side beam 20 being squeezed and deformed during a collision, resulting in damage to the cable skin and leakage.

[0082] Optionally, the charging port holder 60 is provided at one end of the roof rail 20 for connection with the A-pillar 201. Since this part of the roof rail 20 is connected to the A-pillar 201 and has higher strength, providing the charging port holder 60 here can minimize the impact on the strength of the roof rail 20.

[0083] In order to facilitate the fixing of the charging port 60, as shown in FIG. Figure 12 As shown, in one embodiment of the present disclosure, the vehicle front cabin structure 100 further includes a charging port mounting member 90. The charging port mounting member 90 has a mounting opening, the charging port seat 60 is fixed to the mounting opening, and the charging port mounting member 90 is fixed to the recessed portion 24, and at least a portion of the charging port mounting member 90 is in contact with the surface of the recessed portion 24.

[0084] By setting a charging port mounting member 90 in the recessed portion 24, it is possible to conveniently fix the charging port seat 60, and the charging port mounting member 90 can also be used to strengthen the strength of the recessed portion 24, compensate for the possible reduction in strength of the upper side beam 20 after the recess, and ensure that the recessed portion 24 also has sufficient strength.

[0085] Alternatively, as Figure 12As shown, in an embodiment of the present disclosure, the charging port mounting member 90 includes a mounting member main body and a plurality of lugs that extend and bend outward from the mounting member main body toward the outside of the mounting port. At least a part of the lugs are attached to the outer surface of the upper side beam 20, thereby increasing the strength of the recessed portion 24 and facilitating the fixing of the charging port seat 60 to the upper side beam 20 through the lugs.

[0086] For convenient wiring and to minimize the length of the cable as much as possible, in an embodiment of the present disclosure, as Figure 5 、 12 shown, the vehicle front compartment structure 100 further includes an engine compartment 30 for mounting the powertrain. A wire passing hole 421 for allowing the high-voltage wire of the charging port to pass through is provided in the wheel housing 42. The wire passing hole 421 communicates with the engine compartment 30, and there is a wire passing cavity 31 between the charging port seat 60 and the upper side beam 20.

[0087] As Figure 13 shown, the cable at the charging port seat 60 only needs to pass through the wire passing cavity 31 to reach the wheel housing 42, and then pass through the wire passing hole 42 on the wheel housing 42 to enter the engine compartment 30, realizing electrical connection with the charging port on the powertrain in the engine compartment 30. When performing the wiring assembly operation, it only needs to pass through the charging port seat 60 and the wheel housing 42 with a single-layer plate that is convenient to operate and has a large space, thereby reducing the labor intensity of the operating workers and improving the assembly work efficiency.

[0088] To strengthen the strength of the wire passing hole 421 of the wheel housing 42, as Figure 5 shown, in an embodiment of the present disclosure, the vehicle front compartment structure 100 further includes a wire passing hole reinforcing plate 422. A first passing hole is provided in the wire passing hole reinforcing plate 422, and the first passing hole corresponds to and communicates with the wire passing hole 421. The wire passing hole reinforcing plate 422 is fixed to the inner side of the wheel housing 42, thereby strengthening the strength of the wheel housing 42 with the opening and ensuring the force-bearing performance of the wheel housing 42.

[0089] To increase the sealing performance at the wheel housing 42, in an embodiment of the present disclosure, as Figure 13 shown, the vehicle front compartment structure 100 further includes a sealing cover plate 423. A second passing hole for allowing the wire harness to pass through is provided in the sealing cover plate 423, and a sealing member is provided around the second passing hole. The second passing hole corresponds to and communicates with the wire passing hole 421, and the sealing cover plate 423 is fixed to the outer side of the wheel housing 42. A sealing member is also provided on the mating surface between the sealing cover plate 423 and the wheel housing 42, thereby increasing the sealing performance at the location of the wire passing hole 421 of the wheel housing 42 and preventing water from flowing into the engine compartment 30 through the wire passing hole 421.

[0090] To prevent leakage to the charging port when the water chute 10 drains water, which may cause a risk of electric leakage, as described above, in the present disclosure, the drain port 14 of the water chute 10 opens towards the bottom of the vehicle instead of being opened on the upper side beam 20. This way, it neither occupies the space at the upper side beam 20 nor poses a risk of electric leakage. Thus, the waterproof and anti-electric leakage problems when the charging port is arranged on the front fender 53 are solved.

[0091] Furthermore, to increase the waterproof property of the charging port, a charging through hole corresponding to the charging port seat 60 is provided on the front fender 53, and a charging port cover 531 is arranged on the outer surface of the fender. The charging port cover 531 is pivotally mounted to cover the charging through hole. Two charging port covers 531 may be provided on the fender, one of the charging port covers 531 corresponding to the DC charging socket and the other charging port cover 531 corresponding to the AC charging socket.

[0092] According to another aspect of the present disclosure, a vehicle is also provided, which includes the above-described vehicle front cabin structure 100.

However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0094] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure does not separately describe various possible combination manners.

[0095] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
