[0029] It should be noted that the sequence of the following embodiments is not limited as the preferred sequence of the embodiments of the present application. In the following embodiments, the description of each embodiment is focused on, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.
[0030] Please refer to Figures 1-4 , a frame type automobile front anti-collision beam is shown in the figure, which comprises an upper beam part 100, a middle beam part 200, a lower beam part 300 and a mounting back plate 400, the upper beam part 100, the middle beam part 200 and the lower beam part 300 are arranged in sequence from top to bottom and are fixed relative to each other, thereby forming a frame type automobile front anti-collision beam.
[0031] Specifically, the upper beam part 100 comprises an upper anti-collision beam 110 and an upper energy absorption box 120, the upper energy absorption box 120 is arranged between the upper anti-collision beam 110 and the mounting back plate 400, thereby enabling the upper anti-collision beam 110 and the mounting back plate 400 to be mounted and fixed, preferably welded and fixed, that is, one side (front end) of the upper energy absorption box 120 is welded and fixed with the upper anti-collision beam 110, and the other side (rear end) is mounted and fixed with the mounting back plate 400.
[0032] The upper anti-collision beam 110 is an integrally formed box structure containing a cavity. The whole of the upper anti-collision beam 110 is in a smooth arc shape, and the center of the arc of the upper anti-collision beam 110 faces the center of the vehicle, so that the upper anti-collision beam 110 can better absorb the collision force generated when the vehicle collides.
[0033] The two upper energy absorption boxes 120 are fixedly arranged at one side of the upper anti-collision beam 110 close to the center of the vehicle, and are respectively fixedly connected with the two mounting back plates 400. The upper energy absorption box 120 is a hollow cavity, which can better absorb the collision force. The upper side of the upper energy absorption box 120 close to the upper anti-collision beam 110 is provided with a first flange 121. Two first flanges 121 are arranged along the up-down direction of the upper anti-collision beam 110, so that the upper energy absorption box 120 forms a structure after being rotated 90° clockwise like a similar “N” character. The two first flanges 121 are respectively fixed with the upper anti-collision beam 110, so that the upper energy absorption box 120 can be embedded into the upper anti-collision beam 110.
[0034] The advantages of such arrangement are that, on the one hand, the upper anti-collision beam 110 and the upper energy absorption box 120 can be fixed well; on the other hand, and more importantly, by arranging the first flange 121 on the upper energy absorption box 120, the structure of the upper anti-collision beam 110 can be avoided from being damaged, the coherence of the overall structure of the upper anti-collision beam 110 is ensured, and the collision capacity of the whole structure is ensured.
[0035] The positions of the two upper energy absorption boxes 120 are preferably corresponding to the front longitudinal beams of the vehicle, that is, the two upper energy absorption boxes 120 are at the same horizontal height as the front longitudinal beams of the lower vehicle body, and are preferably located on the same straight line in the front-rear direction (Y direction) of the vehicle, so as to ensure the crash performance of the whole vehicle.
[0036] Similarly, the middle beam part 200 is arranged below the upper beam part 100. The middle beam part 200 includes a middle anti-collision beam 210 and two middle energy absorption boxes 220. The two middle energy absorption boxes 220 are fixedly arranged at one side of the middle anti-collision beam 210 close to the center of the vehicle, and are respectively fixedly connected with the two mounting back plates 400. The middle energy absorption box 220 is a hollow cavity, which can better absorb the collision force. The upper side of the middle energy absorption box 220 close to the upper anti-collision beam 110 is provided with a second flange 221. Two second flanges 221 are arranged along the up-down direction of the middle anti-collision beam 210, so that the middle energy absorption box 220 forms a structure after being rotated 90° clockwise like a similar “N” character. The two second flanges 221 are respectively fixed with the middle anti-collision beam 210, so that the middle energy absorption box 220 can be embedded into the middle anti-collision beam 210.
[0037] The middle anti-collision beam 210 is also a box structure with a cavity formed by integral molding. The overall shape of the middle anti-collision beam 210 is smooth and arc-shaped, and the center of the arc of the middle anti-collision beam 210 is directed towards the center of the vehicle, so that the middle anti-collision beam 210 can better absorb the collision force generated when the vehicle collides. The positions of the middle anti-collision beam 210 and the upper anti-collision beam 110 in the front-rear direction (X direction) of the vehicle are substantially the same, so that the upper anti-collision beam 110 and the middle anti-collision beam 210 can be contacted at the same time when the vehicle collides, thereby better offsetting the collision force. The Z-direction position of the middle anti-collision beam 210 is set at the same height as the subframe of the vehicle, so that the middle anti-collision beam 210 is flush with the subframe, thereby providing better collision protection. Correspondingly, the two middle energy absorption boxes 220 are respectively arranged at the corresponding positions of the subframe, so that the middle energy absorption boxes 220 and the subframe are in the same straight line.
[0038] The height (Z-direction size) of the middle anti-collision beam 210 is smaller than the height of the upper anti-collision beam 110. The purpose of this arrangement is to ensure that the collision force can be dispersed as soon as possible while reducing the weight of the entire structure as much as possible to ensure that the weight of the entire vehicle meets the requirements. In a preferred embodiment, the height of the middle anti-collision beam 210 in the region between the two middle energy absorption boxes 220 is smaller than that in other regions, so that the middle anti-collision beam 210 has a shape in which the height of the two ends is smaller than that of the middle part.
[0039] For the positions of the two middle energy absorption boxes 220, it is preferred that they correspond to the subframe of the vehicle, i.e., the two middle energy absorption boxes 220 are respectively at the same horizontal height as the subframe of the vehicle, and are preferably located in the same straight line in the inward-outward direction (Y direction) of the vehicle, thereby ensuring the crash performance of the entire vehicle.
[0040] The lower cross beam part 300 is arranged below the middle cross beam part 200 and is fixedly arranged with the middle energy absorption boxes 220 of the middle cross beam part 200, preferably by bolt fixation. That is, the upper side of the lower cross beam part 300 is fixed with the energy absorption boxes of the middle cross beam part 200. The lower side of the lower cross beam part 300 is fixedly arranged with the radiator of the vehicle. The lower cross beam part 300 is arranged behind the upper anti-collision beam 110 of the upper cross beam part 100 and the middle anti-collision beam 210 of the middle cross beam part 200, so that in the event of a frontal collision, the collision object first contacts the upper cross beam part 100 and the middle cross beam part 200, and then contacts the lower cross beam part 300 after the upper cross beam part 100 and the middle cross beam part 200 collapse to a specific shape.
[0041] Specifically, the lower cross beam part 300 comprises a first horizontal plate 310 and a second horizontal plate 320 fixedly arranged; the first horizontal plate 310 is arranged above the second horizontal plate 320. The first horizontal plate 310 is a plate structure with high sides and low middle, and the second horizontal plate 320 is a plate structure with low sides and high middle. Thus, after the first horizontal plate 310 and the second horizontal plate 320 are combined in the up-down direction, a structure with gaps at both ends and adhesion in the middle region is formed. That is, the lower cross beam part comprises a first horizontal plate and a second horizontal plate fixedly arranged from top to bottom; the first horizontal plate is a plate structure with high sides and low middle; the second horizontal plate is a plate structure with low sides and high middle; the middle part of the first horizontal plate is fixedly adhered to the middle part of the second horizontal plate, so that the first horizontal plate and the second horizontal plate form a structure with gaps at both ends and adhesion in the middle region.
[0042] The purpose of such arrangement is that, on the one hand, the lower cross beam part 300 needs to be fixedly connected with the radiator, and in the case that the installation position of the radiator itself is relatively fixed, the lower cross beam part 300 needs to be in contact with the radiator to achieve the fixation of the radiator. On the other hand, the lower cross beam part 300 itself is part of the collision protection device, and needs to be in contact with the middle cross beam part 200 to improve the collision protection capability. On the other hand, by making the first horizontal plate 310 and the second horizontal plate 320 have gaps between the two ends, the first horizontal plate 310 and the second horizontal plate 320 can form an open cavity at both ends, thereby ensuring the rigidity of the lower cross beam part 300 itself and improving the collision absorption effect.
[0043] In a preferred embodiment, the first horizontal plate 310 is provided with a third flange 321 towards the side of the second horizontal plate 320 at the position where the first horizontal plate 310 and the second horizontal plate 320 have gaps at both ends, so that the first horizontal plate 310 and the second horizontal plate 320 are enclosed into a structure with open cavities at both ends and adhesion in the middle. The purpose of such arrangement is that, on the one hand, the adhesion in the middle of the first horizontal plate 310 and the second horizontal plate 320 can ensure that both the first horizontal plate 310 and the second horizontal plate 320 can be fixedly connected with the radiator below, thereby ensuring the fixation force of the first horizontal plate 310 and the second horizontal plate 320 on the radiator. On the other hand, the open cavities at both ends can well ensure the energy absorption effect. Naturally, it can be understood that the mounting point of the first horizontal plate 310 and the middle energy absorption box 220 is arranged in the region where the first horizontal plate 310 and the second horizontal plate 320 form the open cavities, so as to improve the collision absorption capability of the lower cross beam part 300 and the middle cross beam part 200.
[0044] Further, the first horizontal plate 310 of the lower cross beam part 300 is fixedly connected with the mounting back plate 400, preferably provided with a bolt hole on the third flange 321 of the first horizontal plate 310 towards the second horizontal plate 320, so that the first horizontal plate 310 is bolted with the mounting back plate 400 to further strengthen the collision absorption capability.
[0045] In a preferred embodiment, at least one lightening hole 330 is arranged in the area where the first cross plate 310 and the second cross plate 320 are attached to each other, and a plurality of lightening holes 330 are arranged to further reduce the weight of the lower cross beam part 300, thereby ensuring the light weight of the whole vehicle.
[0046] It should be noted that the specific manufacturing method of the lower cross beam part 300 is not limited in the present application, as long as the structure of the two ends having an open cavity and the middle attachment can be formed. In an alternative embodiment, the lower cross beam part 300 comprises a first mounting box, a second mounting box and a connecting plate, the connecting plate is fixedly connected with the first mounting box and the second mounting box on both sides to form the lower cross beam part 300. The first mounting box and the second mounting box each have a cavity. The cavity can be an open cavity or a closed cavity, which is not limited in the present application. For the first mounting box and the second mounting box, it is preferred to be integrally formed by die casting, and of course it can also be made by other ways, which is not limited in detail.
[0047] Therefore, the upper cross beam part 100, the middle cross beam part 200, the lower cross beam part 300 and the mounting back plate 400 provided by the present application can strengthen the parts between each other, and the design of the three anti-collision cross beams of the upper cross beam part 100, the middle cross beam part 200 and the lower cross beam part 300 can increase the contact area of the anti-collision beam and the barrier in the MPDB collision condition, reduce the penetration amount of the barrier, improve the collision test performance and score; in addition, the reinforcing piece connecting the upper cross beam and the middle cross beam can support and connect the two cross beams together, and in combination with the lower vehicle body and the subframe of the chassis, a frame type anti-collision beam structure with higher collision protection effect can be provided, and the energy absorption performance in the collision can be improved.
[0048] In addition, by making the lower cross beam part 300 contact and fix with the middle energy absorption box 220 of the middle cross beam part 200, the crushing stability of the middle energy absorption box 220 can be effectively improved, and by integrating the lower cross beam part 300 with the radiator, the special radiator frame structure is replaced, which can further save the manufacturing cost of the automobile and improve the integration efficiency of the production line.
[0049] Please continue to refer to Figures 1-4 , the frame type automobile front anti-collision beam further comprises a side reinforcing piece 500. The side reinforcing piece 500 is arranged on both sides of the upper cross beam part 100 and the middle cross beam part 200, and is fixedly connected with the upper cross beam part 100 and the middle cross beam part 200, thereby making the upper cross beam part 100 and the lower cross beam part 300 "hand in hand" to form a whole. The side reinforcing piece 500 is preferably a "N" shaped connecting rod, the side reinforcing piece 500 extends in an arc shape from both ends of the upper anti-collision beam 110 and the middle anti-collision beam 210, and the arc center is arranged towards the center of the vehicle.
[0050] Further, by setting the side reinforcement 500, the upper cross beam part 100 and the middle cross beam part 200 can be well supported in the vertical direction (Z direction) during the crushing process in the MPDB (Mobile Progressive Deformable Barrier) mobile barrier deformation barrier test, FFB (56 km / h frontal rigid wall) and other front collision conditions, increasing the contact area with the collision object, especially for the MPDB condition, the overall contact can significantly optimize the penetration damage to the barrier.
[0051] In addition, as Figure 4 shown, in the SOB collision (small offset collision) condition, by setting the side reinforcement 500, the side reinforcement 500 is in contact with the barrier, which can guide the vehicle to generate a lateral force away from the barrier, push the vehicle away from the barrier, thereby reducing the collision overlap of the barrier to the vehicle, reducing the impact, and reducing the risk of occupant injury. At the same time, the outwardly extending side reinforcement 500 can also flexibly set the headlamp mounting point due to the proximity of the headlamp, saving related mounting structural parts.
[0052] In a preferred embodiment, the upper energy-absorbing box 120 and the middle energy-absorbing box 220 are both welded by steel plate stamping parts, and by controlling the heat treatment process parameters, etc., the strength performance of the plate material for manufacturing the upper energy-absorbing box 120 and the middle energy-absorbing box 220 is gradiently enhanced from the front to the back, so that it is more stable and sufficient during the collision crushing process.
