[0002] With the increasing popularity of vehicles, vehicle safety is considered by more and more consumers to be one of the most important indicators of vehicle performance. Among them, the drainage system is an area on the vehicle that is prone to collisions. In order to improve the safety performance of the drainage system for pedestrians and occupants, the drainage system is often designed to be easily deformable. Because the drainage system will deform as a whole when it is subjected to a collision, the maintenance cost is relatively high in subsequent maintenance. Utility Model Content

The front plate is provided with a first crumple zone, and the upper plate is provided with a second crumple zone. The maximum load borne by the second crumple zone is greater than the maximum load borne by the first crumple zone.

[0005] In one embodiment of this utility model, a first bend is provided on the lower plate, the first bend forming a third collapse, and the maximum load borne by the third collapse is greater than the maximum load borne by the second collapse.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1

[0035] The water trough structure of this utility model includes a first connecting member 1 and a front plate 2, an upper plate 3 and a lower plate 4 arranged in sequence. The first connecting member 1 is provided with a first connecting end 5 and a second connecting end 6. The first connecting end 5 is connected to the connection between the front plate 2 and the upper plate 3, and the second connecting end 6 is connected to the lower plate 4. The front plate 2 is provided with a first contraction point, and the upper plate 3 is provided with a second contraction point. The maximum load borne by the second contraction point is greater than the maximum load borne by the first contraction point.

[0036] This application achieves graded crumple zone during vehicle collisions by using a first connecting member 1 on the drainage channel structure, thereby reducing the maintenance costs of the drainage channel structure after a collision. Specifically, the drainage channel structure of this application includes a front plate 2, an upper plate 3, a lower plate 4, and a first connecting member 1. The front plate 2, upper plate 3, and lower plate 4 are connected in a zigzag pattern from top to bottom, as shown below. Figure 1 As shown. The first connector 1 is provided with a first connecting end 5 and a second connecting end 6. The first connecting end 5 is connected to the connection between the front plate 2 and the upper plate 3, and the second connecting end 6 is connected to the lower plate 4, as shown. Figure 1 , Figure 2 , Figure 3As shown, the second connecting end 6 can be connected to different positions on the lower plate 4. Because the water trough structure is equipped with the first connecting member 1, the connection between the front plate 2 and the upper plate 3 is supported by the first connecting member 1, improving the connection stability between the upper plate 3 and the lower plate 4. The front plate 2 has a first collapse point, and the upper plate 3 has a second collapse point. The first connecting member 1, in conjunction with the first and second collapse points, achieves sequential collapse of the front plate 2 and the upper plate 3. Furthermore, the maximum load that the water trough structure can withstand includes a first load and a second load. The first load is less than the second load. When the collision load between the impactor and the water trough structure reaches the first load, the front plate 2 collapses at the first collapse point, and the upper plate 3 maintains structural integrity under the support of the first connecting member 1. When the collision load between the impactor and the water trough structure reaches the second load, the front plate 2 forms a first collapse at the first collapse point, and the upper plate 3 forms a second collapse at the second collapse point, while the first connecting member 1 collapses simultaneously.

[0037] The water trough structure of this application places the first connector 1 between the upper plate 3 and the lower plate 4. The first connector 1 improves the connection stability between the upper plate 3 and the lower plate 4. At the same time, the first connector 1, together with the first crumple point on the front plate 2 and the second crumple point on the upper plate 3, enables the front plate 2 and the upper plate 3 to achieve graded crumple when subjected to collision load. That is, when the collision load between the impacting object and the water trough structure is small, the front plate 2 crumples, and subsequent maintenance only requires maintenance of the front plate 2, without the need to maintain the upper plate 3; when the collision load between the impacting object and the water trough structure is large, the front plate 2, the first connector 1, and the upper plate 3 all crumple, and subsequent maintenance requires maintenance of the front plate 2, the first connector 1, and the upper plate 3. Therefore, the graded crumple adopted in this application reduces the maintenance cost of the water trough structure.

[0038] In one embodiment, the lower plate 4 is provided with a first bend 7, which forms a third collapse point. The maximum load borne by the third collapse point is greater than the maximum load borne by the second collapse point.

[0039] This application further reduces the maintenance cost of the water channel structure by utilizing the third crumple zone on the lower plate 4. Specifically, such as... Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the lower plate 4 has a first bend 7, which forms a third crumple zone. When the water channel structure is subjected to an impact load, the lower plate 4 can achieve a third crumple zone. Furthermore, the maximum load that the water channel structure can withstand includes a first load, a second load, and a third load, which increase sequentially. When the collision load between the impactor and the water channel structure reaches the first load, the front plate 2 collapses at the first crumple zone, while the upper plate 3 and lower plate 4 maintain structural integrity under the support of the first connector 1. Subsequent maintenance only requires repair of the front plate 2. When the collision load between the impactor and the water channel structure reaches the second load, the front plate 2 collapses at the first crumple zone, and the upper plate 3 collapses at the second crumple zone. Simultaneously, the first connector 1 collapses, and the lower plate 4 undergoes elastic deformation. Subsequent maintenance only requires repair of the front plate 2, the upper plate 3, and the first connector 1. When the collision load between the impactor and the water channel structure reaches the third load, the front plate 2 collapses at the first crumple zone, the upper plate 3 collapses at the second crumple zone, and simultaneously, the first connector 1 collapses, and the lower plate 4 collapses at the third crumple zone. Subsequent maintenance requires repair of the front plate 2, the upper plate 3, the first connector 1, and the lower plate 4. Therefore, the water channel structure of this application reduces its post-collision maintenance costs. Furthermore, by absorbing the impact energy generated during a collision in stages through graded crumple, not only can the safety protection performance for pedestrians be improved when they are the colliding object, but the speed at which the impact energy is transmitted to the passenger compartment can also be delayed, reducing the peak impact force that passengers are subjected to instantly. Therefore, the water channel structure of this application also improves the safety protection performance for pedestrians and passengers.

[0040] In one embodiment, the front plate 2 has an upwardly protruding protrusion 8, which forms a first contraction, and the upper plate 3 has a second bend 9, which forms a second contraction.

[0041] This application achieves the collapse of the front plate 2 through a first collapse point and the collapse of the upper plate 3 through a second collapse point. Specifically, as shown... Figure 6 As shown, a protrusion 8 is provided on the front panel 2. The protrusion 8 protrudes upward and is used to connect the windshield 30. The windshield 30 can be arranged on the protrusion 8 in two ways, the first being as follows... Figure 12 As shown, the stop of the windshield 30 is located on the protrusion 8, the second type as... Figure 11As shown, the stop of the windshield 30 extends downward beyond the protrusion 8 by a certain distance. For the first arrangement of the windshield 30, when a collision occurs between the object and the windshield 30, the specific collapse process is as follows: the object first impacts the windshield 30. When the impact energy generated by the object is less than or equal to the first load, the elastic deformation of the windshield 30 and the protrusion 8 absorbs the impact energy. When the impact energy generated by the object is greater than the first load but less than or equal to the second load, the windshield 30 breaks, the impact energy is transmitted downwards, and the protrusion 8 is flattened. Since the collision point of the object is located above the connection between the front panel 2 and the upper panel 3, the front panel 2 rotates clockwise around its connection with the upper panel 3, causing the front panel 2 to be in a compressed state and undergo elastic deformation. The elastic deformation of the front plate 2 absorbs part of the impact energy. At this time, the front plate 2 experiences a first collapse at the first collapse point formed by the protrusion 8. When the impact energy generated by the colliding object is greater than the second load but less than or equal to the third load, the impact energy continues to be transmitted downwards, and a second collapse occurs at the second collapse point formed by the second bend 9 of the upper plate 3. At the same time, the first connecting piece 1 collapses, and the front plate 2 has undergone plastic deformation. When the impact energy generated by the colliding object is greater than the third load, the impact energy continues to be transmitted downwards, and a third collapse occurs at the third collapse point formed by the first bend 7 on the lower plate 4. At the same time, the elastic deformation generated by the lower plate 4 rotating clockwise around the first bend 7 absorbs part of the energy.In the second arrangement of the windshield 30, when a collision occurs between the object and the windshield 30, the specific collapse process is as follows: the object first impacts the windshield 30. When the impact energy generated by the object is less than or equal to the first load, the elastic deformation of the windshield 30 and the protrusion 8 absorbs the impact energy. When the impact energy generated by the object is greater than the first load but less than or equal to the second load, the windshield 30 breaks, the impact energy is transmitted downwards and flattens the protrusion 8. At this time, the front panel 2 experiences the first collapse at the first collapse point formed by the protrusion 8. Since the stop of the windshield 30 is located a distance below the connection between the front panel 2 and the upper panel 3, after the protrusion 8 is flattened, the impact energy acts directly on the connection between the front panel 2 and the upper panel 3, and there is no front panel 2 surrounding the connection between it and the upper panel 3. The clockwise rotation at the connection point; when the impact energy generated by the colliding object is greater than the second load and less than or equal to the third load, the impact energy continues to be transmitted downward in a direction perpendicular to the windshield 30, and a second collapse occurs at the second collapse point formed at the second bend 9 of the upper plate 3. At the same time, the first connecting piece 1 collapses, and the elastic deformation generated by the counterclockwise rotation of the upper plate 3 relative to the lower plate 4 around the second bend 9, and the elastic deformation generated by the clockwise rotation of the front plate 2 relative to the upper plate 3 around the connection point of the two absorb part of the impact energy; when the impact energy generated by the colliding object is greater than the third load, the impact energy continues to be transmitted downward, and a third collapse occurs at the third collapse point formed at the first bend 7 on the lower plate 4. At the same time, the elastic deformation generated by the clockwise rotation of the lower plate 4 around the first bend 7 absorbs part of the energy.

[0042] In one embodiment, the upper plate 3 includes a first connecting plate 10, a second connecting plate 11 and a third connecting plate 12 arranged sequentially. A third bend 13 is provided between the first connecting plate 10 and the second connecting plate 11, and a second bend 9 is provided between the second connecting plate 11 and the third connecting plate 12.

[0043] This application achieves the second collapse through the upper plate 3. Specifically, as follows: Figure 4 As shown, the upper plate 3 comprises three parts: a first connecting plate 10, a second connecting plate 11, and a third connecting plate 12, which are arranged sequentially. Further, as... Figure 4As shown, a third bend 13 is provided between the first connecting plate 10 and the second connecting plate 11, and a second bend 9 is provided between the second connecting plate 11 and the third connecting plate 12. The third bend 13 connects the first connecting plate 10 and the second connecting plate 11 at a preset angle, and the second bend 9 connects the second connecting plate 11 and the third connecting plate 12 at a preset angle. The second bend 9 is used to allow the upper plate 3 to collapse when a colliding object impacts the water tank structure, thereby absorbing the impact energy. Simultaneously, the elastic deformation of the first connecting plate 10 and the second connecting plate 11 at the third bend 13 can also absorb some of the impact energy. Both the second bend 9 and the third bend 13 bend towards one side of the lower plate 4.

[0044] In one embodiment, the lower plate 4 is recessed in a direction away from the front plate 2 to form a groove 14, and the first connector 1 is also provided with a third connecting end 15, and the second connecting end 6 and the third connecting end 15 are respectively connected to the two side walls of the groove 14.

[0045] This application improves the connection stability between the upper plate 3 and the lower plate 4 by using the first connector 1. Specifically, as shown... Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the lower plate 4 is recessed towards the bottom of the vehicle to form a groove 14, and the left and right sidewalls of the groove 14 form a first sidewall 23 and a second sidewall 24. To further improve the connection stability between the upper plate 3 and the lower plate 4, the first connector 1 is configured as a triangular structure, with a connecting end corresponding to each corner of the triangle. Therefore, the first connector 1 has a total of three connecting ends, namely, a first connecting end 5, a second connecting end 6, and a third connecting end 15. The first connecting end 5 is connected to the connection between the front plate 2 and the upper plate 3, the second connecting end 6 is connected to the first sidewall 23, and the third connecting end 15 is connected to the second sidewall 24. The triangular first connector 1 connects the connection between the front plate 2 and the upper plate 3, the first sidewall 23 of the lower plate 4, and the second sidewall 24 of the lower plate 4 together, improving the connection stability between the upper plate 3 and the lower plate 4. In addition, as Figure 13 and Figure 14 As shown, a reinforcing plate 31, a wiper motor mounting bracket 32, an instrument panel crossbeam mounting bracket 33, and a sub-instrument panel mounting bracket 26 are also provided between the first side wall 23 and the second side wall 24; the reinforcing plate 31 is used to improve the connection strength of the lower plate 4, the wiper motor mounting bracket 32 ​​is used to install the wiper motor, the instrument panel crossbeam mounting bracket 33 is used to connect the instrument panel crossbeam, and the sub-instrument panel mounting bracket 26 is used to connect the sub-instrument panel. Figure 8As shown, the first connector 1 is also provided with a reinforcing rib 28 and a wire harness mounting bracket 29. The reinforcing rib 28 is used to improve the deformation resistance of the first connector 1, and the wire harness mounting bracket 29 is used to fix the wire harness of the wiper motor. The first connecting end 5 has a slender and weakened structure to facilitate the collapse of the first connector 1 in the vertical direction.

[0046] In one embodiment, the water trough structure further includes a second connector 16, one end of which is connected to the front plate 2 and the other end of which is connected to the upper plate 3, forming a buffer cavity 25 between the front plate 2, the second connector 16 and the upper plate 3.

[0047] This application improves the impact energy absorption capacity of the front plate 2 through the second connector 16. Specifically, as shown... Figure 9 As shown, the second connector 16 is disposed above the upper plate 3, and the second connector 16 is connected to the front plate 2 and the upper plate 3 to form a buffer cavity 25, which improves the impact energy absorption capacity of the front plate 2. Furthermore, the top of the second connector 16 is connected to the top of the front plate 2, and both ends of the upper plate 3 are connected to the bottom of the second connector 16 and the bottom of the front plate 2, respectively.

[0048] In one embodiment, the second connector 16 includes a fourth connecting plate 17, a fourth bend 18, a fifth connecting plate 19, a fifth bend 20, and a sixth connecting plate 21 arranged sequentially. The fourth connecting plate 17 is connected to the front plate 2, and the sixth connecting plate 21 is connected to the upper plate 3.

[0049] This application improves the impact energy absorption capacity through the fourth bend 18 and the fifth bend 20 on the second connector 16. Specifically, as... Figure 10 As shown, the structure of the second connector 16 is similar to that of the upper plate 3. The second connector 16 includes a fourth connecting plate 17, a fifth connecting plate 19, and a sixth connecting plate 21, which are arranged sequentially. Further, as... Figure 10 As shown, the fourth bend 18 connects the fourth connecting plate 17 and the fifth connecting plate 19 at a preset angle, and the fifth bend 20 connects the fifth connecting plate 19 and the sixth connecting plate 21 at a preset angle. When the impacting object strikes the water channel structure, the impact energy first flattens the protrusion 8, and the first collapse absorbs part of the impact energy through the protrusion 8 on the front plate 2. When the front plate 2 rotates clockwise relative to its connection with the upper plate 3, the elastic deformation of the fourth bend 18 and the fifth bend 20 on the second connecting member 16 can absorb part of the impact energy, thereby improving the impact energy absorption rate during the first collapse. Both the fourth bend 18 and the fifth bend 20 bend towards the lower plate 4.

[0050] In one embodiment, the first connector 1 is provided with a weight reduction hole 22, which is a collapse hole.

[0051] The first connector 1 in this application achieves collapsibility through a collapse hole. Specifically, as shown... Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the first connector 1 improves the connection stability between the upper plate 3 and the lower plate 4 through its own triangular structure. However, the strength of the first connector 1 cannot be too high, otherwise the second collapse will not be easily achieved. Therefore, a through hole is provided on the first connector 1. The through hole is both a weight-reducing hole 22 to reduce the weight of the water channel structure and a collapse hole to facilitate the collapse of the first connector 1. Therefore, by setting the first connector 1 and the collapse hole, it can be achieved that: when the collision load is greater than the first load and less than or equal to the second load, the front plate 2 collapses, while the upper plate 3 and the lower plate 4 do not collapse; when the collision load is greater than the second load and less than or equal to the third load, the front plate 2 and the upper plate 3 collapse, while the lower plate 4 does not collapse; and when the collision load is greater than the third load, the front plate 2, the upper plate 3, and the lower plate 4 collapse.

[0052] In one embodiment, sealant (not shown in the figure) and structural adhesive (not shown in the figure) are provided at the connection between the front plate 2 and the upper plate 3, as well as between the upper plate 3 and the lower plate 4.

[0053] This application achieves the sealing performance of the water channel structure through sealant, preventing water on the windshield 30 from flowing into the cockpit, and improves the strength of the water channel structure through structural adhesive. Specifically, sealant and structural adhesive are applied between the front panel 2 and the upper panel 3, and the welding between the front panel 2 and the upper panel 3 ensures the sealing ability and connection strength between them; similarly, sealant and structural adhesive are applied between the upper panel 3 and the lower panel 4, and the welding between the upper panel 3 and the lower panel 4 ensures the sealing ability and connection strength between them.

[0054] In one embodiment, the protrusion 8 is provided with a downwardly recessed groove 27.

[0055] This application uses silicone sealant to connect the windshield 30 to the front panel 2. Specifically, as shown... Figure 5 As shown, a protrusion 8 is provided on the front panel 2, which is used to mount the windshield 30. Furthermore, a groove 27 is provided on the protrusion 8, which is used to fill with silicone sealant. The sealant connects the windshield 30 to the protrusion 8, thereby connecting the windshield 30 to the front panel 2. In addition, the groove 27 enhances the vertical strength of the protrusion 8 to a certain extent.

[0056] Example 2

[0057] A front bulkhead assembly includes a drainage channel structure and a front bulkhead panel (not shown in the figure). The drainage channel structure is disposed on the front bulkhead panel. The drainage channel structure includes a first connector 1 and a front panel 2, an upper panel 3, and a lower panel 4 arranged sequentially. The first connector 1 is provided with a first connecting end 5 and a second connecting end 6. The first connecting end 5 is connected to the connection between the front panel 2 and the upper panel 3, and the second connecting end 6 is connected to the lower panel 4. The front panel 2 is provided with a first crumple zone, and the upper panel 3 is provided with a second crumple zone. The maximum load borne by the second crumple zone is greater than the maximum load borne by the first crumple zone.

[0058] The front bulkhead assembly of this application includes a drainage channel structure and a front bulkhead panel, with the drainage channel structure positioned on top of the front bulkhead panel. The drainage channel structure places a first connector 1 between the upper panel 3 and the lower panel 4, improving the connection stability between them. Simultaneously, the first connector 1, in conjunction with a first crumple zone on the front panel 2 and a second crumple zone on the upper panel 3, enables graded crumple of the front panel 2 and the upper panel 3 under impact loads. Specifically, when the impact load between the impactor and the drainage channel structure is small, the front panel 2 crumples, requiring only maintenance of the front panel 2 without needing to repair the upper panel 3. When the impact load is large, the front panel 2, the first connector 1, and the upper panel 3 crumple, requiring maintenance of all three components. Therefore, this application reduces the maintenance cost of the drainage channel structure, thereby reducing the maintenance cost of the front bulkhead assembly.

[0059] Example 3

[0060] A vehicle includes a front bulkhead assembly, which includes a drainage channel structure and a front bulkhead panel (not shown in the figure). The drainage channel structure is disposed on the front bulkhead panel and includes a first connector 1 and a front panel 2, an upper panel 3, and a lower panel 4 arranged sequentially. The first connector 1 is provided with a first connecting end 5 and a second connecting end 6. The first connecting end 5 is connected to the connection between the front panel 2 and the upper panel 3, and the second connecting end 6 is connected to the lower panel 4. The front panel 2 is provided with a first crumple zone, and the upper panel 3 is provided with a second crumple zone. The maximum load borne by the second crumple zone is greater than the maximum load borne by the first crumple zone.

[0061] The vehicle of this application includes a front bulkhead assembly, which includes a channel structure and a front bulkhead panel. The channel structure is connected to the top of the front bulkhead panel. The channel structure places a first connector 1 between the upper panel 3 and the lower panel 4. The first connector 1 improves the connection stability between the upper panel 3 and the lower panel 4. Simultaneously, the first connector 1, in conjunction with a first crumple zone on the front panel 2 and a second crumple zone on the upper panel 3, enables the front panel 2 and the upper panel 3 to achieve graded crumple under impact loads. That is, when the impact load between the impactor and the channel structure is small, the front panel 2 crumples, and subsequent maintenance only requires repair of the front panel 2, without needing to repair the upper panel 3. When the impact load between the impactor and the channel structure is large, the front panel 2, the first connector 1, and the upper panel 3 crumple, and subsequent maintenance requires repair of the front panel 2, the first connector 1, and the upper panel 3. Therefore, this application reduces the maintenance cost of the channel structure, reduces the maintenance cost of the front bulkhead assembly, and thus reduces the vehicle's maintenance cost.

[0062] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed.
