AI Technical Summary
In existing vehicle layout schemes, the passenger compartment space is constrained by the front structure layout, especially the arrangement of the front bulkhead and steering system, which limits the expansion of the passenger compartment.
By placing the motor in the front engine compartment, positioning the front bulkhead above the motor and in front of the front wheels, and placing the steering gear in the front engine compartment and in front of the motor, the traditional "motor-steering gear-front bulkhead" layout is completely reconstructed. Some components of the air conditioning system are also moved forward into the front engine compartment, thus moving the front bulkhead and steering system forward.
Without changing the overall vehicle wheelbase, the passenger compartment space is significantly increased, improving space utilization efficiency, ergonomics, and ride comfort.

Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a front structure of a vehicle and a vehicle. Background Technology
[0002] With the development of automotive electrification technology, more and more vehicles are using electric motors as the sole or primary drive source, gradually eliminating the bulky and complex traditional internal combustion engines and their auxiliary systems, resulting in significant space redundancy in the engine compartment. This structural change provides unprecedented design freedom for the overall vehicle platform layout, especially creating favorable conditions for optimizing the passenger compartment space.
[0003] Passenger cabin space is one of the important indicators for measuring the ergonomics and ride comfort of a vehicle. Under the same wheelbase, how to maximize passenger cabin space and improve the overall space utilization efficiency of the vehicle is an important issue in current automotive platform architecture design.
[0004] However, in existing vehicle layouts, passenger compartment space remains constrained by the front structure. For example, influenced by traditional design inertia and component placement logic, the front bulkhead of existing vehicles is positioned behind the center of the front wheels to avoid the powertrain installation area, while the steering gear in the steering system is located behind the motor, with the steering column connected to the steering gear extending through the bulkhead into the passenger compartment. Even with significant simplification and reduction in the size of the powertrain structure, this layout constraint persists without coordinated optimization of the layout of the motor, bulkhead, and steering system, thus limiting further expansion of passenger compartment space. Utility Model Content

[0020] In the above scheme, by setting the kingpin inclination angle a between the kingpin axis and the central plane of the front wheel as a≤10°, the motion outward envelope of the front suspension system in the second direction Y is effectively reduced, so that the inner walls of the left and right wheel covers can be closer to the central planes of the respective front wheels, thereby increasing the lateral spacing between the left and right wheel covers under the condition that the overall width of the vehicle body remains unchanged, significantly improving the lateral available space of the foot area of the passenger cabin, and improving the ergonomics and ride comfort.

[0025] Optionally, the height H1 of the motor is ≤ 260 mm.
[0026] In the above scheme, by controlling the height H1 of the motor to be within 260 mm, the space occupation of the motor in the third direction Z is effectively reduced, so that the front panel can be arranged above the motor under a limited vertical clearance, while avoiding the intrusion into the foot area of the passenger cabin, thereby providing a key structural condition for improving the human engineering layout and ride comfort in the vehicle under the premise of ensuring the power performance.

[0058] The passenger cabin space is one of the important indicators to measure the level of vehicle ergonomics and ride comfort. Under the same wheelbase, how to maximize the passenger cabin space and improve the space utilization efficiency of the whole vehicle is an important issue in the current automobile platform architecture design. However, in the existing vehicle arrangement scheme, the passenger cabin space is still restricted by the front structure layout. For example, due to the influence of traditional design inertia and component arrangement logic, the existing front panel of the vehicle is arranged behind the wheel center of the front wheel to avoid the installation area of the power system, and the steering gear of the steering system is arranged behind the motor, and the steering column connected with the steering gear extends through the front panel to the passenger cabin, which restricts the further expansion of the passenger cabin space.
[0059] Therefore, in order to realize the forward movement of the front panel and the steering system to increase the passenger cabin space, on the one hand, the embodiment of the present application provides a vehicle front structure, in which the vehicle front-rear direction is set as the first direction X, the vehicle left-right direction is set as the second direction Y, and the vehicle up-down direction is set as the third direction Z. Please refer to Figure 1 and Figure 2 , the vehicle front structure comprises a front engine compartment 100, a passenger cabin 200, and a motor 1, a front wheel 2, a front panel 3, and a steering system 4, wherein:
[0060] The front engine compartment 100 is arranged at the front of the vehicle and is used to accommodate power and steering related components; the passenger cabin 200 is arranged behind the front engine compartment 100, and the two are separated in structure and function by the front panel 3 in the first direction X;
[0061] The motor 1 is installed in the front engine compartment 100, and in this embodiment, preferably, in order to reduce the occupation of the motor 1 to the foot space of the passenger cabin 200 in the third direction Z, a flat motor structure with small height in the third direction Z in the installed state is preferentially adopted;
[0062] The front wheel 2 is provided with two, which are arranged on the left and right sides of the front engine compartment 100 in the second direction Y, and the front wheel 2 has a wheel center;
[0063] The front panel 3 is located above the motor 1 in the third direction Z, and is located in front of the wheel center of the front wheel 2 in the first direction X, which breaks through the limitation that the front panel 3 needs to retreat to the rear of the wheel center of the front wheel 2 to avoid the power assembly in the traditional arrangement;
[0064] The steering system 4 comprises a steering gear 41 and a steering column 42; wherein the steering gear 41 is installed in the front engine compartment 100 and is located in front of the motor 1 in the first direction X; one end of the steering column 42 is in transmission connection with the steering gear 41, and the other end extends through the front panel 3 into the passenger cabin 200 and is connected with a steering wheel.
[0065] The vehicle front structure provided by the embodiment of the present application completely reconfigures the traditional "motor-steering gear-front wall" layout from front to back by arranging the motor 1 in the front engine compartment 100, arranging the front wall 3 above the motor 1 and in front of the wheel center of the front wheel 2, and arranging the steering gear 41 in the front engine compartment 100 and in front of the motor 1. Not only is the compact integrated layout of the components in the front engine compartment 100 achieved, but the intrusion depth of the rear end of the front engine compartment 100 into the passenger compartment 200 is also significantly compressed. Thus, the overall front movement of the front wall 3 and the steering system 4 is achieved under the premise of keeping the wheelbase unchanged, the passenger compartment space is increased, the space utilization efficiency of the vehicle is improved, and the man-machine engineering level and the ride comfort of the vehicle are significantly improved.
[0066] In other embodiments, as shown in Figure 1 , Figure 3 The vehicle front structure further includes an air conditioning system 5, which includes a distribution box 51, a heater core 52, an evaporator 53, a blower 54, an air conditioning filter 55, and an internal and external circulation air door 56. The distribution box 51 is arranged in the passenger compartment 200 as a core component for air distribution and air outlet control. Part or all of the heater core 52, the evaporator 53, the blower 54, the air conditioning filter 55, and the internal and external circulation air door 56 are arranged in the front engine compartment 100. Preferably, as shown in the embodiment, all of the heater core 52, the evaporator 53, the blower 54, the air conditioning filter 55, and the internal and external circulation air door 56 are arranged in the front engine compartment 100.
[0067] In the above scheme, by retaining the distribution box 51 in the passenger compartment 200 and arranging at least part of the heater core 52, the evaporator 53, the blower 54, the air conditioning filter 55, and the internal and external circulation air door 56 of the air conditioning system 5 in the front engine compartment 100, the occupation of the air conditioning system 5 to the front space of the passenger compartment 200 is effectively reduced, and the thickness and intrusion depth of the instrument panel assembly are reduced, thereby further releasing the available space in the foot and knee areas without sacrificing the air conditioning performance, and improving the man-machine engineering level and the ride comfort of the vehicle.
[0068] In other embodiments, continuing as Figure 3As shown, the front compartment 100 is provided with a front cross beam 6 extending along the second direction Y; the distribution box 51 is installed at the rear side of the front bulkhead 3; the heater core 52, the evaporator 53, the blower 54, the air conditioner filter 55 and the inside-outside circulation air door 56 are all arranged in the front compartment 100, specifically, the heater core 52, the evaporator 53, the air conditioner filter 55 and the inside-outside circulation air door 56 are installed at the front side of the front bulkhead 3, and the blower 54 is installed on the front cross beam 6.
[0069] In the above scheme, by connecting the distribution box 51 to the rear side of the front bulkhead 3 and placing it in the passenger compartment 200, and arranging the heater core 52, the evaporator 53, the blower 54, the air conditioner filter 55 and the inside-outside circulation air door 56 and other air conditioning components that need to be cooled or have a large volume on the front side of the front bulkhead and in the front compartment, the front bulkhead 3 is used to realize the efficient space distribution of the air conditioning system 5 between the front compartment 100 and the passenger compartment 200, significantly reducing the thickness and longitudinal depth of the instrument panel assembly, effectively releasing the front foot and knee space of the passenger compartment 200, further increasing the internal space of the passenger compartment 200, and improving the vehicle ergonomics and ride comfort; at the same time, the structural rigidity of the front cross beam 6 provides a stable and low-vibration mounting base for the blower 54, which can effectively reduce the noise and vibration of the blower 54 during operation.
[0070] In some embodiments, as shown in FIG. 1, Figure 4 As shown, the vehicle front structure further includes a front suspension system 7, a steering knuckle of the front suspension system 7 rotates around a virtual rotation axis, i.e. the kingpin axis 71 of the front suspension system 7, the included angle between the kingpin axis 71 and the center plane of the front wheel 2 forms a kingpin inclination angle α, and α≤ 10°.
[0071] In the above scheme, by setting the kingpin inclination angle α between the kingpin axis 71 and the center plane of the front wheel 2 as α≤ 10°, the motion envelope of the front suspension system 7 in the second direction Y is effectively reduced, so that the inner walls of the left and right wheel covers can be closer to the center planes of the respective front wheels 2, thereby increasing the lateral distance between the left and right wheel covers under the premise of constant overall vehicle width, significantly improving the lateral available space of the foot area of the passenger compartment 200, and improving the ergonomics and ride comfort. In some embodiments, α can be 4°, 4.5°, 5°, 5.5°, 6°, 7°, 8°, 9°, etc.
[0072] In some embodiments, as shown in FIG. 1, Figure 1 As shown, the minimum distance L1 between the front bulkhead 3 and the center of the front wheel 2 in the vehicle front-rear direction (i.e. the first direction X) is 50mm to 150mm.
[0073] In the above scheme, by setting the minimum distance L1 between the front panel 3 and the wheel center of the front wheel 2 to 50-150 mm, the forward movement of the front panel 3 is effectively realized, without changing the wheelbase and the overall vehicle length, the intrusion depth into the passenger compartment 200 is greatly reduced, thereby significantly expanding the foot and knee space, and improving the ergonomics and ride comfort. In some embodiments, L1 can be 60 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, etc.

[0075] In the above scheme, by setting the minimum distance L2 between the steering device 41 and the motor 1 to 25-30 mm, high-density integration of the two in the first direction X within the front compartment 100 is realized; this layout effectively avoids the space occupation caused by the rearward movement of the steering device 41 towards the passenger compartment 200, significantly expands the available space in the front part of the passenger compartment 200 under the premise of ensuring assembly process and dynamic safety clearance, and improves the ergonomics and ride comfort. In some embodiments, L2 can be 25.5 mm, 26 mm, 26.5 mm, 27 mm, 28 mm, 29 mm, etc.
[0076] In some other embodiments, as shown in Figure 1 the height H1 of the motor 1 is ≤260 mm.
[0077] In the above scheme, by controlling the height H1 of the motor 1 to be within 260 mm, the space occupation in the third direction Z is effectively reduced, so that the front panel 3 can be arranged above the motor 1 under limited vertical clearance, while avoiding the intrusion into the foot area of the passenger compartment 200, thereby providing a key structural condition for improving the ergonomics and ride comfort of the vehicle under the premise of ensuring the power performance. In some embodiments, H1 can be 150 mm, 180 mm, 200 mm, 220 mm, 250 mm, etc.

[0079] In the above scheme, by arranging the top surface of the front longitudinal beam 8 to be higher than the floor of the passenger cabin 200 and lower than the top surface of the front bumper beam 9, while controlling the height difference H2 between the top surface of the front longitudinal beam 8 and the top surface of the front bumper beam 9 to be 40-50 mm and the height difference H3 between the top surface of the front longitudinal beam 8 and the floor of the passenger cabin 200 to be 120-130 mm, the front longitudinal beam 8 is arranged downwardly while meeting the collision force transmission requirement, which can effectively avoid the problem of lifting the foot position of the passenger cabin 200 and compressing the foot space due to the front longitudinal beam 8 being too high, significantly improve the riding posture and comfort, and at the same time, the rigidity and safety performance of the front structure are considered. In some embodiments, H2 can be 41 mm, 42 mm, 44.5 mm, 45 mm, 46 mm, 47 mm, 49 mm, etc., and H3 can be 121 mm, 123 mm, 125 mm, 125.5 mm, 127 mm, 128 mm, 129 mm, etc.
