Description

Technical Field

[0001] The present invention relates to the technical field of metrological verification, and more specifically, to a rhino-like body collision and rollover structure. Background Art

[0002] In automobile collision accidents, the proportion and casualty probability of frontal collisions are the highest. In severe accident statistics, the casualty rates of vehicle rollovers after frontal collisions and the intrusion of the power system into the passenger compartment caused by collisions are the highest.

[0003] Existing technologies all use traditional anti-collision beams and longitudinal beams to deform and absorb energy, and make the passenger compartment strong to prevent passengers from being squeezed and ensure safety.

[0004] Regarding the collision safety of electric vehicles, as the driving range of electric vehicles increases, the weight of the vehicle is getting higher and higher. The original collision energy absorption strategy formulated for fuel vehicle models with a curb weight of 1400 - 1700 kg is difficult to work in vehicles with a weight of 1900 - 2300 kg.

[0005] For traditional fuel vehicles, their weight distribution is forward, and the power assembly has a great influence. However, for electric vehicles, their electric motors are relatively small, and the battery weight is very large and located below the passenger compartment. This results in the center of gravity and weight distribution of electric vehicles being relatively rearward, making it easier for the vehicle to roll forward during a frontal collision, thus causing serious casualties.

[0006] Therefore, how to provide a body collision and anti-rollover structure that can avoid damage caused by the intrusion of the electric motor into the passenger compartment has become a technical problem that needs to be solved urgently in this field. Summary of the Invention

Detailed description of the specific implementation mode

[0039] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.

[0040] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention or its application or use.

[0041] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods and devices should be regarded as part of the specification.

[0042] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values.

[0043] It should be noted that like reference numerals and letters refer to like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0044] According to Figures 1 to 9 As shown, the present invention provides a rhino-like body collision and rollover structure, including a front cross beam 11, a rear cross beam 12, and upper longitudinal beams 1 and lower longitudinal beams 2 symmetrically arranged.

[0045] The upper longitudinal beam 1 and the lower longitudinal beam 2 on the same side are connected by two front and rear support rods 8, and the front cross beam 11 and the rear cross beam 12 are respectively connected between the front support rod 8 and the rear support rod 8 on the front side.

[0046] The front end of the upper longitudinal beam 1 is also connected with an upper anti-collision beam 3, and the front end of the lower longitudinal beam 2 is connected with a lower anti-collision beam 4; a rhino horn 6 with a forwardly curved end is provided above the upper longitudinal beam 1, and an obliquely arranged rhino horn support 7 is also provided between the rear side of the rhino horn 6 and the upper longitudinal beam 1.

[0047] A motor moving beam 13 is provided between the front and rear support rods 8 on the same side, and a motor 5 is carried between the motor moving beams 13; front brackets 14 and rear brackets 15 are respectively provided on the front cross beam 11 and the rear cross beam 12, and the front brackets 14 and the rear brackets 15 are used to support the motor 5.

[0048] Further, a vertically obliquely arranged front support rod 9 is also provided between the upper anti-collision beam 3 and the front cross beam 11. A horizontally obliquely arranged rear support rod 10 is also provided between the rear cross beam 12 and the rear section of the lower longitudinal beam 2.

[0049] In this embodiment, the motor 5 beam is fixed to the upper longitudinal beam 1. The motor 5 beam and the support rod 8 are connected in the Z direction by bolts. After the bolts fail and break, the support rod 8 will lose Z-direction support.

[0050] The front end of the front support rod 9 is connected to the upper anti-collision beam 3, and the Z-direction height is relatively high. The rear end of the front support rod 9 is connected to the front cross beam 11, and the Z-direction height is relatively low. The front end of the rear support rod 10 is connected to the rear cross beam 12, and the Z-direction height is relatively high. The rear end of the rear support rod 10 is connected to the rear section of the lower longitudinal beam 2, and the Z-direction height is relatively low. Therefore, when receiving a collision squeeze, the front support rod 9 will transmit force to cause the front cross beam 11 to fold downward at the connection point, and the rear support rod 10 will transmit force to cause the rear cross beam 12 to fold upward at the connection point.

[0051] In summary, the front and rear crossbeams 12 will have the following characteristics: When being squeezed during a frontal collision, after the front and rear crush zones of the lower longitudinal beam 2 are crushed, the lower longitudinal beam 2 loses its load-bearing function. The force is transmitted obliquely downward from the front strut 9 to the front crossbeam 11. The front crossbeam 11 is pulled downward, and the two bolts connecting its two ends to the motor 5 beam break and fail, causing the front crossbeam 11 to move downward. Then the force is transmitted from the front strut 9 to the motor 5 and then to the rear strut 10, and is transmitted obliquely downward to the rear section of the lower longitudinal beam 2. Since the rear section of the lower longitudinal beam 2 is very rigid, the rear crossbeam 12 is pushed upward, and the two bolts connecting its two ends to the motor 5 beam break and fail, causing the rear crossbeam 12 to move upward.

[0052] At this time, all the peripheral connections in the middle section of the entire lower longitudinal beam 2 have failed or broken, and the entire front and rear crossbeams 12, the middle section of the lower longitudinal beam 2, and the motor 5 can sink. Then according to Figure 3 As shown, according to the arrangement of the induction ribs in the rear crush zone of the lower anti-collision beam 4, there are three induction ribs on the upper surface, two induction ribs on the side surface, and no induction ribs are designed on the lower surface, in order to generate a bend towards the upper surface at this position, so that the middle section of the lower longitudinal beam 2 can sink.

[0053] Furthermore, one end of the front strut 9 connected to the front crossbeam 11 is provided with a front support block 17. A front support groove corresponding to the front support block 17 is formed on the front crossbeam 11. The front support block 17 is embedded in the front support groove, and the front bracket 14 is arranged directly above the front support groove.

[0054] Furthermore, a first opening 18 is provided above the front support block 17. A first notch 21 corresponding to the first opening 18 is formed on the front crossbeam 11, and the first notch 21 partially coincides with the first opening 18; the front bracket 14 has a hollow structure, and its bottom is provided with a front connecting plate connected to the side wall of the front crossbeam 11. A front rigid column strut 16 is arranged inside the front bracket 14 to enhance the strength of the front bracket 14;

[0055] The front rigid column strut 16 has a barbell structure, and its two ends are attached to the inner side wall of the front bracket 14, and the bottom of the front rigid column strut 16 abuts against the rear side wall of the front support block 17 so that the front rigid column strut 16 can be stabilized inside the front bracket 14.

[0056] Furthermore, first sliding grooves 19 are formed on both sides of the bottom of the front support block 17. First sliding blocks 20 matching the first sliding grooves 19 are formed on the side wall of the front support groove. The dimensions of both ends of the front rigid column strut 16 are smaller than the dimensions of the first opening 18 and the first notch 21; when the upper anti-collision beam 3 is hit, the front strut 9 can drive the front support block 17 to move backward along the first sliding block 20, so that the front rigid column strut 16 can fall into the front support block 17.

[0057] In this embodiment, the front support block 17 is a hollow square block with five sides enclosed and an open top. The front strut 9 is connected to the front support block 17 as a whole. Inside the front bracket 14, a front rigid column strut 16 is designed. The strength of the front bracket 14 is weak and insufficient to support the motor 5, and it entirely depends on the front rigid column strut 16 for support.

[0058] When the front strut 9 transmits the frontal collision force, it squeezes the front support block 17 to slide backward in the front support groove of the front crossbeam 11, and the front rigid column strut 16 drops downward into the front support block 17. At this time, the front bracket 14 cannot effectively support the motor 5, and the motor 5 presses down and crushes the front bracket 14.

[0059] Further, one end of the rear strut 10 connected to the rear crossbeam 12 is provided with a rear support block 22. A rear support groove corresponding to the rear support block 22 is opened on the rear crossbeam 12. The rear support block 22 is embedded in the rear support groove, and the rear bracket 15 is arranged directly above the rear support groove.

[0060] Still further, a second opening is provided above the rear support block 22. A second notch corresponding to the second opening is opened on the rear crossbeam 12, and the second notch partially coincides with the second opening; the rear bracket 15 is of a hollow structure, and its bottom is provided with a rear connecting plate connected to the side wall of the rear crossbeam 12. A rear rigid column strut 23 is arranged inside the rear bracket 15 to enhance the strength of the rear bracket 15;

[0061] The rear rigid column strut 23 is of a barbell structure, and its two ends are attached to the inner side wall of the rear bracket 15, and the bottom of the rear rigid column strut 23 abuts against the rear side wall of the rear support block 22 so that the rear rigid column strut 23 can be stabilized inside the rear bracket 15.

[0062] Still further, second sliding grooves are opened on both sides of the bottom of the rear support block 22. Second sliders matched with the sliding grooves are opened on the side wall of the rear support groove. The dimensions of both ends of the rear rigid column strut 23 are smaller than the dimensions of the second opening and the second notch; when the upper anti-collision beam 3 is impacted, the rear strut 10 can drive the rear support block 22 to move backward along the second slider so that the rear rigid column strut 23 can fall into the rear support block 22.

[0063] Similar to the structures in the front bracket 14, the front strut 9, and the front crossbeam 11, and achieving similar technical effects, the difference is that the main function of the rear crossbeam 12 is to jack up upward to ensure the sinking of the motor 5.

[0064] When a frontal collision occurs to the vehicle, the upper anti-collision beam 3 and the lower anti-collision beam 4 collide with an object and transmit the force backward, and the front crush zones of the upper longitudinal beam 1 and the lower longitudinal beam 2 are axially crushed.

[0065] The collision continues, the rear crush zone of the lower longitudinal beam 2 is axially crushed, and the lower longitudinal beam 2 fails. At the same time, the front strut 9 and the rear strut 10 act, the front cross beam 11 of the motor 5 moves downward, and the rear cross beam 12 moves upward. At the same time, the front bracket 14 and the rear bracket 15 are crushed. As a result, the motor 5 tilts forward and sinks as a whole. It is possible to reduce the X-direction dimension occupied by the motor 5 and ensure the integrity of the occupant compartment.

[0066] The collision continues. At this time, the motor 5 begins to be impacted and moves backward. The lower longitudinal beam 2 continues to fail and is bent, driving the whole motor 5 to be crushed downward, avoiding the direct front of the occupant's vital parts, which are currently in front of the feet and the battery. At this time, the vehicle begins to tilt forward during the collision. The upper part of the rhino horn 6 invades the powertrain of the opponent vehicle and jams, or other collision objects, thus preventing the vehicle from tilting forward continuously. The rhino horn 6 that is impacted above will transmit the force downward, further pushing the motor 5 and the cross beam downward.

[0067] Finally, the collision ends, and the motor 5 moves downward and is embedded in the lower side of the front bulkhead. Due to a certain angle of flipping, the rear section of the motor 5 does not impact the battery but invades the occupant's leg space, avoiding the leakage and combustion of the whole vehicle.

[0068] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for the purpose of illustration and not for the purpose of limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
