Detailed Description
Embodiments of the present invention will be described in detail below, by way of example with reference to the accompanying drawings.
A vehicle front cabin structure 100 and a vehicle according to an embodiment of the present invention are described below with reference to fig. 1 to 5.
The vehicle front cabin structure 100 according to the embodiment of the first aspect of the invention includes: left side rail 10, right side rail 20, powertrain 40, air conditioning system 30, and crash transfer.
As shown in fig. 1, the right side member 20 and the left side member 10 are disposed opposite to each other in the Y direction, and an arrangement space is formed between the left side member 10 and the right side member 20, the powertrain 40 is connected to the vehicle body in the arrangement space, the air conditioning system 30 is connected to the vehicle body in the arrangement space, and the air conditioning system 30 is disposed adjacent to the powertrain 40. The Y direction is the width direction of the whole vehicle, namely the left-right direction, the X direction is the length direction of the whole vehicle, namely the front-back direction, and the Z direction is the height direction of the whole vehicle, namely the up-down direction.
The crash transfer member includes a first push block 50 and a second push block 60, the first push block 50 being located between the left side of the power assembly 40 and the air conditioning system 30 as a whole and the left side rail 10, and the second push block 60 being located between the right side of the power assembly 40 and the air conditioning system 30 as a whole and the left side rail 10.
It should be noted that, the first pushing block 50 and the second pushing block 60 are configured to be capable of transmitting the collision force, and the first pushing block 50 and the second pushing block 60 may be made of rigid materials, so as to have an effect of better absorbing the collision energy.
The number of the first pushing blocks 50 and the second pushing blocks 60 may be one or more, and when the number is plural, the plurality of first pushing blocks 50 may be disposed at intervals from each other, and the plurality of second pushing blocks 60 may be disposed at intervals from each other. The first pushing block 50 may be connected to the left side member 10 on one side, or may be connected to the air conditioning system 30 on the other side; the second pusher block 60 may be connected to the right side member 20 on one side or to the power train 40 on the other side.
At 25% small offset impact, the impact force transmission path is: the side member of the left side member 10 and the right side member 20 that is close to the collision side, one of the first push block 50, the power assembly 40, and the air conditioning system 30, the other of the power assembly 40, and the air conditioning system 30, the second push block 60, and the side member of the left side member 10 and the right side member 20 that is far from the collision side.
The 25% small offset collision is a test for detecting the collision safety of vehicles, is a test experiment for detecting the safety of vehicles by the American Highway safety insurance Association IIHS (Insurance Institute for Highway Safety), and aims to check the damage degree of the vehicles after the vehicles strike the solid matters (barriers) with the speed of 40 miles per hour and the impact area of the vehicles is only equivalent to 25% of the width of the vehicles, and correspondingly score the damage degree. The test mainly considers that the safety threat to personnel in the vehicle is larger when the collision similar to the test state occurs in the driving process, so that the safety of the vehicle in the test state needs to be considered in the vehicle body design process.
The powertrain 40 and the air conditioning system 30 are each secured to the vehicle body, respectively, and the housings may be connected to each other or may be maintained at a suitable spacing that will dissipate in the event of a 25% small offset crash, thereby bringing the powertrain 40 and the air conditioning system 30 into contact with each other to transmit Y-direction forces.
Further, describing the air conditioning system 30 as being located near the left side rail 10 and the powertrain 40 as being located near the right side rail 20, a 25% offset crash test may be selected in at least one of the following ways: 1) When the front left side of the vehicle head is subjected to 25% small offset collision, the impact force is transmitted to the right side frame 20 along the left side frame 10, the first pushing block 50, the air conditioning system 30, the power assembly 40 and the second pushing block 60, so that the vehicle can sideslip to the right; 2) In the event of a 25% small offset collision in the front right of the vehicle head, the impact force is transmitted to the left side member 10 along the right side member 20, the second push block 60, the power assembly 40, the air conditioning system 30 and the first push block 50, so that the vehicle can sideslip to the left.
In the vehicle front cabin structure 100, a first push block 50, an air conditioning system 30, and a power train 40, and a second push block 60 are disposed between the left side member 10 and the right side member 20 in this order along the Y direction. Wherein, the air conditioning system 30 may be disposed near the left longitudinal beam 10 and the powertrain 40 near the right longitudinal beam 20, and the collision force transmission path is: the air conditioning system comprises a left longitudinal beam 10, a first pushing block 50, an air conditioning system 30, a power assembly 40, a second pushing block 60 and a right longitudinal beam 20; of course, the air conditioning system 30 may be disposed near the right longitudinal beam 20 and the power assembly 40 near the left longitudinal beam 10, where the collision force transmission path is as follows: the left longitudinal beam 10, the first pushing block 50, the power assembly 40, the air conditioning system 30, the second pushing block 60 and the right longitudinal beam 20.
Therefore, the collision transmission members are arranged on one side of the left longitudinal beam 10 and the right longitudinal beam 20 close to the arrangement space, so that when a 25% small offset collision occurs in the front cabin structure 100 of the vehicle, a force or component force along the Y direction can be generated under the transmission path of the collision force, the vehicle can sideslip towards the side far away from the collision, the possibility that the cab is impacted in the front direction due to excessive energy absorption and bending or compression of the longitudinal beams of the vehicle is avoided, and the life safety of drivers and passengers is improved.
In the particular embodiment shown in fig. 1, the first push block 50 is located between the air conditioning system 30 and the left side rail 10, the first push block 50 is connected to the left side rail 10, the first push block 50 has a first spacing from the air conditioning system 30 in the Y-direction, and the first spacing is configured to disappear upon a 25% small offset collision such that the first push block 50 presses the air conditioning system 30.
That is, there is a first distance between the first push block 50 and the air conditioning system 30, which is not contacted when the vehicle is not subjected to a severe collision, and is deformed due to the compression of the left side member 10 when the collision occurs, the left side member 10 moves toward the air conditioning system 30 together with the first push block 50 after being compressed and deformed, and the first push block 50 stops against the air conditioning system 30, transmitting force to the air conditioning system 30 and the power train 40.
Therefore, under the action of the first pushing block 50, the force generated by collision is transmitted from the left longitudinal beam 10 to the power assembly 40, so that at least part of the collision force can be transmitted along the Y direction, the front of a driver is prevented from being impacted, and the driving safety is improved.
Further, a second push block 60 is located between the air conditioning system 30 and the right side rail 20, the second push block 60 is connected to the right side rail 20, the second push block 60 has a second spacing from the powertrain 40 in the Y-direction and the second spacing is configured to disappear upon a 25% small offset collision, such that the powertrain 40 presses the second push block 60.
As shown in fig. 1 and 4, when the force generated when the left side member 10 is collided is transmitted to the power unit 40, the power unit 40 is displaced in the Y direction, and the force is buffered at the second pitch and then is stopped against the second pusher 60, and finally is transmitted to the right side member 20, thereby causing the side slip and the offset of the vehicle. Of course, when the right side member 20 is subjected to a 25% small offset collision, the force is transmitted to the left side member 10 along the Y direction, and the principle is the same and will not be described in detail.
Therefore, the second pushing block 60 is arranged on one side, close to the power assembly 40, of the right longitudinal beam 20, so that the transmitted collision force can be transmitted to the right longitudinal beam 20, the vehicle can sufficiently absorb energy to shift or sideslip, and the structure of the vehicle and the safety of drivers and passengers of the vehicle are better protected. Meanwhile, a second interval is arranged between the second pushing block 60 and the power assembly 40, so that the second pushing block 60 and the power assembly 40 are kept independent in a normal driving state, and the second interval is arranged so that vehicles can not interfere with each other in normal driving, and the performance of NVH (Noise Vibration Harshness) is not reduced.
Alternatively, the second push block 60 corresponds to a damper mount of the vehicle body in the Y direction. I.e. the side of the right longitudinal beam 20 facing away from the power assembly 40 is provided with a shock absorber mounting seat (not shown in the figures) and the other side, i.e. the side facing the arrangement space, is provided with a second push block 60.
Therefore, the second pushing block 60 is arranged corresponding to the shock absorber mounting seat, so that the force generated by collision can be further buffered, and the shock absorber has good energy absorption effect.
Optionally, the first spacing and the second spacing are 20mm-25mm. Therefore, the distances between the first pushing block 50 and the air conditioning system 30 and the distances between the second pushing block 60 and the power assembly 40 are controlled, so that abnormal sound caused by collision in the running process of the vehicle can be avoided, and the force can be timely transmitted to the adjacent air conditioning system 30 and power assembly 40 when the vehicle is in collision deformation.
Specifically, the first pushing block 50 and the second pushing block 60 are hollow structures and have at least one crush cavity. Alternatively, the materials of the first and second push blocks 50 and 60 may be 45 steel.
Therefore, the first pushing block 50 and the second pushing block 60 are both arranged into a hollow structure, so that on one hand, the use of materials can be reduced, the weight of the pushing blocks and the production and manufacturing cost are reduced, and on the other hand, the effect of absorbing collision energy is better when the pushing blocks are extruded by the crumple cavities.
Optionally, the first pushing block 50 is formed by welding a plurality of square tubes, the collapsing cavity is formed by an inner hole of the square tube, and the first pushing block 50 includes: a plurality of first square pipes 51 and a plurality of second square pipes 52. Each first square tube 51 extends along the Z direction, the plurality of first square tubes 51 are sequentially arranged along the X direction to form a plate body, the second square tubes 52 are vertically connected to the plate body and are positioned on the same side of the plate body, the extending directions of the second square tubes 52 and the extending directions of the first square tubes 51 are mutually perpendicular, one part of the second square tubes 52 is arranged close to one end of the plate body, the other part of the second square tubes 52 is arranged close to the other end of the plate body, the two parts of the second square tubes 52 are separated in the extending directions of the first square tubes 51 to form a line passing space 53 for a line of the air conditioning system 30 to pass through, and the second square tubes 52 and the left longitudinal beam 10 are fixed through the auxiliary frame mounting seat 70.
As shown in fig. 2 and 3, the first pushing block 50 has a concave shape, the opening direction faces the subframe mounting seat 70, the first square tube 51 arranged along the X direction and the second square tube 52 extending along the Y direction are perpendicular to each other, and the length of the first square tube 51 is significantly longer than that of the second square tube 52. The sub-frame mount 70 refers to a member provided near the front of the vehicle body, which is directed downward from the side of the layout space, and to which the first pusher 50 can be mounted.
Specifically, the plurality of second square tubes 52 may be vertically connected to two ends of the first square tube 51 disposed side by side, that is, a surface of the first square tube 51 connected to the second square tube 52 and a surface of the subframe mount 70 facing the first push block 50 are parallel to each other, one end of the plurality of second square tubes 52 is fixedly mounted on the subframe mount 70, the other end is vertically connected to the first square tube 51, and a certain wire passing space 53 is formed between the two ends. The square tubes and the subframe mount 70 may be welded to each other. In an actual manufacturing process, each of the first square pipe 51 and the second square pipe 52 forming the first push block 50 may be welded to form a single body, and then mounted to the surface of the subframe mount 70 facing the side of the power assembly 40.
Thus, the plurality of side-by-side first square pipes 51 and the side-by-side second square pipes 52 are welded to form the first pushing block 50, and each square pipe is designed to have a hollow structure, so that the weight of the first pushing block 50 can be reduced, the production cost can be reduced, and the structural strength of the first pushing block 50 can be improved.
In addition, the first pushing block 50 is fixed through the auxiliary frame mounting seat 70, so that vibration and noise can be effectively reduced, riding comfort is improved, the first pushing block 50 and the auxiliary frame mounting seat 70 can be preassembled, and vehicle assembly efficiency and convenience are improved.
Alternatively, the second pusher block 60 may be welded from a plurality of section steel (a bar-type steel material having a certain cross-sectional shape and size), the crush cavity being formed by the inner bore of the section steel, the second pusher block 60 comprising: a plurality of third-party pipes 61, a plurality of fourth-party pipes 62, and a diagonal brace plate 63. Each third-party pipe 61 extends in the Y direction, and a plurality of third-party pipes 61 are connected side by side, each fourth-party pipe 62 extends in the X direction, and the fourth-party pipes 62 are connected perpendicularly to the third-party pipes 61 and constitute an L-shaped plate, and a diagonal brace 63 is connected inside the L-shaped plate, and the ends of the third-party pipes 61 of the L-shaped plate are connected to the right side member 20, and the fourth-party pipes 62 are opposite to the power assembly 40 in the Y direction.

After the fourth pipe 62 is connected to the third pipe 61, a diagonal plate 63 is further provided on the side of the fourth pipe 62 facing away from the power unit 40, so that the third pipe 61 and the fourth pipe 62 can be supported and connected.
Therefore, the third square pipes 61 and the fourth square pipes 62 are vertically connected in an L shape, so that the contact area of the second pushing block 60 and the power assembly 40 in deformation contact can be increased, the force can be better transmitted to the power assembly 40, the weight of the second pushing block 60 can be reduced, and the rigidity and strength of the structure of the second pushing block 60 can be improved.
Further, the first pushing block 50 is disposed forward relative to the second pushing block 60, i.e. the first pushing block 50 and the second pushing block 60 are sequentially distributed in the X direction, and the first pushing block 50 is closer to the vehicle body head.
Therefore, the first pushing block 50 is arranged more forward than the second pushing block 60, after the longitudinal beams are extruded by collision, the vehicle can not only sideslip along the Y direction, but also generate component force along the X direction, so that the vehicle can also generate backward displacement, the safety of a driver can be better protected, the safety of the vehicle is improved, and the transmission of force during collision is facilitated.
A vehicle according to an embodiment of the second aspect of the invention comprises the vehicle front cabin structure 100 of any one of the embodiments described above.
That is, during a 25% small offset collision, the longitudinal beam on the collision side is transferred to the longitudinal beam on the other side through the two pushing blocks, the air conditioning system 30 and the power assembly 40, and the collision force can generate a component force along the Y direction, so that the vehicle can generate lateral displacement in the 25% small offset collision process, the obstacle avoidance can not directly strike the cab, and the stress and the extrusion deformation of drivers and passengers are reduced. At the same time, the greater stiffness of the powertrain 40 provides better resistance to impact deformation.
