Description

Technical Field

[0001] The present invention relates to the technical field of vehicle engineering, and in particular to a reinforcement bracket, an A-pillar assembly and a vehicle. Background Art

[0002] With the advancement of automobile manufacturing technology, people are paying more and more attention to the collision safety performance of passenger cars and the control of noise and vibration inside passenger cars. The control level of interior noise and the strength of the white body have become important indicators of passenger car quality.

[0003] When a car is driving at high speed, the A-pillar at the front of the car is the air inlet, which generates high-speed airflow. The friction between the high-speed airflow and the sheet metal parts produces a strong roar, which seriously affects the comfort of the driver and passengers. The structural strength of the A-pillar is also a key impact point of the whole vehicle collision. Therefore, effectively closing the A-pillar of the car, blocking the airflow, and improving the strength of the A-pillar have become a difficult problem that troubles car design developers.

[0004] In the conventional scheme, a high-expansion foam and a high-rigidity low-expansion foam are generally set in the front section of the A-pillar. The A-pillar cavity expansion rubber block is designed separately from the A-pillar body reinforcement plastic part, and the expansion rubber block is generally designed as a skeleton + EVA foam material structure. The skeleton generally has 1 to 2 installation buckles, and the sheet metal needs to open the same number of installation holes. The sheet metal strength is low and the body safety performance is poor. At the same time, the conventional A-pillar cavity expansion rubber block is generally consistent with the cross-sectional shape of the sheet metal cavity, with a large area and a wide force range. It is easy to deform in the impact of electrophoretic fluid, and the sealing effect after expansion is poor. Summary of the invention

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] Referring to the accompanying drawings Figure 1-Figure 8 The reinforcement bracket 30 according to the embodiment of the present invention is described.

[0040] Reference Figure 1-Figure 3 According to the reinforcement bracket 30 of the first aspect of the present invention, the A-pillar body 10 includes an A-pillar inner panel 11 and an A-pillar reinforcement panel 12. The A-pillar inner panel 11 and the A-pillar reinforcement panel 12 jointly define a cavity 101. The portion of the A-pillar body 10 corresponding to the engine compartment of the vehicle is the A-pillar lower section 21. The portion of the A-pillar body 10 corresponding to the windshield of the vehicle is the A-pillar upper section 22. For example, the A-pillar reinforcement panel 12 may be a part of the side enclosure reinforcement door ring of the vehicle; for example, the A-pillar body 10 also includes an A-pillar outer panel 13 arranged outside the A-pillar reinforcement panel 12. Specifically, the A-pillar outer panel 13 may be a part of the side enclosure outer door ring.

[0041] Reference Figure 3-Figure 6The reinforcing bracket 30 includes a bracket frame 3 and an expansion sound insulation member 4. The bracket frame 3 is disposed in the cavity 101 of the A-pillar upper section 22, and the bracket frame 3 is connected to the A-pillar inner panel 11. Specifically, the bracket frame 3 extends along the extension direction of the A-pillar upper section 22 to strengthen the structural strength of the A-pillar upper section 22. For example, the bracket frame 3 and the A-pillar inner panel 11 can be connected by a snap connection, the bracket frame 3 and the A-pillar inner panel 11 can also be connected by a fastener connection, or the bracket frame 3 and the A-pillar inner panel 11 can also be connected by welding or bonding.

[0042] Reference Figure 4 , Figure 5 and Figure 8 The support frame 3 includes a frame body 31 and an expansion reinforcement member 32, the expansion reinforcement member 32 is embedded in the frame body 31, and the frame body 31 defines an annular groove in a portion close to the lower section 21 of the A-pillar; for example, referring to Figure 8 The skeleton body 31 may include a first plate 311, a second plate 312 and a baffle 313. The first plate 311 and the second plate 312 are spaced apart along the extension direction of the skeleton body 31. The baffle 313 is arranged in a ring shape, and the baffle 313 encloses a bone cavity 3131. The two axial sides of the baffle 313 are respectively connected to the first plate 311 and the second plate 312. The first plate 311, the second plate 312 and the baffle 313 jointly define an annular groove, and the annular groove is enclosed on the outer peripheral side of the bone cavity 3131.

[0043] By embedding the expansion reinforcement member 32 with a relatively large structural strength on the frame body 31, the structural strength of the reinforcement bracket 30 can be effectively improved, while reducing the overall weight of the reinforcement bracket 30, improving the structural strength of the A-pillar body 10, improving the safety performance of the vehicle, and realizing a lightweight design of the vehicle. For example, the frame body 31 can be a plastic part, thereby further reducing the weight of the reinforcement bracket 30.

[0044] The expansion sound insulation member 4 is disposed around the outer peripheral side of the support frame 3, and a part of the expansion sound insulation member 4 is inserted into the annular groove, and the expansion sound insulation member 4 is suitable for expanding after heating to seal the cavity 101; wherein the strength of the expansion reinforcement member 32 is greater than the strength of the expansion sound insulation member 4. For example, the expansion reinforcement member 32 can be made of high-strength low-expansion foamed rubber, and the expansion sound insulation member 4 can be made of low-strength high-expansion foamed rubber.

[0045] During the production of the vehicle, the expansion reinforcement 32 can be first connected to the skeleton body 31, and the expansion sound insulation 4 can be connected to the annular groove of the skeleton body 31. Then, the reinforcement bracket 30 can be connected to the A-pillar inner panel 11, and the A-pillar inner panel 11 can be connected to the A-pillar reinforcement plate 12. The vehicle is then produced by electrophoresis process so that the electrophoretic liquid can flow in the inner cavity of the A-pillar body 10. Then, the expansion sound insulation 4 is heated to cause the expansion sound insulation 4 to expand to connect the inner wall of the inner cavity, thereby sealing the inner cavity of the A-pillar body 10.

[0046] By providing an annular groove on the portion of the skeleton body 31 close to the lower section 21 of the A-pillar, and passing part of the expansion sound insulation member 4 through the annular groove, the skeleton body 31 can limit the expansion sound insulation member 4 through the annular groove, thereby reducing the risk of deformation or displacement of the expansion sound insulation member 4 during vehicle electrophoresis, so that the expansion sound insulation member 4 can be reliably fixed relative to the skeleton body 31, so that the expansion sound insulation member 4 can reliably expand and seal the inner cavity of the A-pillar body 10, effectively absorbing the noise from the lower section 21 of the A-pillar toward the upper section 22 of the A-pillar, reducing the noise transmitted from the upper section 22 of the A-pillar to the cab, and improving the NVH performance of the vehicle.

[0047] Moreover, compared with the solution of independently arranging the support frame 3 and the expansion sound insulation component 4, arranging the expansion sound insulation component 4 on the support frame 3 can eliminate the need to arrange a connection hole on the A-pillar inner panel 11 for connecting with the expansion sound insulation component 4, thereby reducing the number of holes opened on the A-pillar inner panel 11, improving the structural strength of the A-pillar inner panel 11, improving the structural strength of the A-pillar body 10, and improving the safety performance of the vehicle.

[0048] According to the reinforcing bracket 30 of the present invention, by embedding the expansion reinforcement member 32 with relatively large structural strength on the skeleton body 31, the structural strength of the reinforcing bracket 30 can be effectively improved, while the overall weight of the reinforcing bracket 30 can be reduced; by providing an annular groove on the portion of the skeleton body 31 close to the lower section 21 of the A-pillar, and inserting the portion of the expansion sound insulation member 4 into the annular groove, the skeleton body 31 can limit the expansion sound insulation member 4 through the annular groove, thereby reducing the risk of deformation or displacement of the expansion sound insulation member 4 during vehicle electrophoresis, so that the expansion sound insulation member 4 is fixed relative to the skeleton body 31. The expansion sound insulation member 4 can reliably expand and seal the cavity 101 of the A-pillar body 10, effectively absorb the noise from the A-pillar lower section 21 toward the A-pillar upper section 22, reduce the noise transmitted from the A-pillar upper section 22 to the cab, and improve the NVH performance of the vehicle; moreover, the expansion sound insulation member 4 is arranged on the bracket frame 3, and it is not necessary to arrange a clamping hole for clamping with the expansion sound insulation member 4 on the A-pillar inner plate 11, thereby reducing the number of holes opened in the A-pillar inner plate 11, improving the structural strength of the A-pillar inner plate 11, improving the structural strength of the A-pillar body 10, and improving the safety performance of the vehicle.

[0049] Reference Figure 3 , Figure 6 and Figure 8 According to some optional embodiments of the present invention, the skeleton body 31 includes a first plate 311, a second plate 312 and a baffle 313, the first plate 311 and the second plate 312 are arranged at intervals along the extension direction of the skeleton body 31, the baffle 313 is arranged in an annular shape and encloses a bone cavity 3131, and the two axial surfaces of the baffle 313 are respectively connected to the first plate 311 and the second plate 312, and the first plate 311, the second plate 312 and the baffle 313 jointly define an annular groove, which is arranged on the outer peripheral side of the bone cavity 3131; the baffle 313 is provided with an avoidance notch, and part of the expansion sound insulation member 4 is arranged in the bone cavity 3131 through the avoidance notch. In this way, the cross-sectional area of ​​the expansion sound insulation member 4 after expansion can be larger, so that the expansion sound insulation member 4 can more effectively absorb the noise from the lower section 21 of the A-pillar to the upper section 22 of the A-pillar, thereby further reducing the noise transmitted from the upper section 22 of the A-pillar to the cab, and improving the NVH performance of the vehicle.

[0050] Reference Figure 3 , Figure 6 and Figure 8 In some optional embodiments of the present invention, the skeleton body 31 further includes a reinforcing rib 315, the reinforcing rib 315 is connected between the first plate 311 and the second plate 312, and the reinforcing rib 315 is located in the bone cavity 3131. For example, there may be a plurality of reinforcing ribs 315. In this way, the connection strength between the first plate 311 and the second plate 312 can be improved, the structural strength of the skeleton body 31 can be improved, and the reliability of the skeleton body 31 can be improved.

[0051] Reference Figure 3 , Figure 6 and Figure 7 According to some embodiments of the present invention, the expansion sound insulation member 4 is a strip structure, and the head and tail of the expansion sound insulation member 4 are snap-connected together. When the expansion sound insulation member 4 is enclosed in the annular groove, one end thereof can be fixed in the annular groove, and the other end can be passed around the skeleton body 31 and connected to one end thereof. Compared with the expansion sound insulation member 4 arranged in an annular shape, the expansion sound insulation member 4 can be connected without expanding the expansion sound insulation member 4 outward, which can reduce the risk of damage to the expansion sound insulation member 4, improve the reliability of the expansion sound insulation member 4, and improve the reliability of the reinforcement bracket 30. Moreover, the snap-connection has a simple structure and is easy to use, which is convenient for assembling the expansion sound insulation member 4 and improving the assembly efficiency of the reinforcement bracket 30.

[0052] Reference Figure 3 , Figure 6 and Figure 7According to some embodiments of the present invention, the two ends of the expansion sound insulation member 4 are respectively a first end and a second end, the portion of the expansion sound insulation member 4 facing the A-pillar inner plate 11 and including the first end is the first section 41, the portion of the expansion sound insulation member 4 facing the A-pillar inner plate 11 and including the second end is the second section 42, the first section 41 and the second section 42 are overlapped in the width direction of the vehicle, and the first section 41 and the second section 42 are connected by snapping. After the expansion sound insulation member 4 expands, the second section 42 can abut against the inner wall of the inner cavity and squeeze the first section 41 in the width direction of the vehicle, so that the first section 41 and the second section 42 are reliably connected, reducing the risk of the first section 41 and the second section 42 being separated from each other, effectively ensuring the sealing effect of the expansion sound insulation member 4 on the inner cavity, and improving the reliability of the reinforcement bracket 30.

[0053] Reference Figure 3 , Figure 6 and Figure 7 In some embodiments of the present invention, the first section 41 includes a first main body 411 and a first protrusion 412, the first protrusion 412 is connected to one end of the first main body 411 facing the second section 42, and the first protrusion 412 is located at a portion of the first main body 411 away from the A-pillar inner panel 11; that is, the first main body 411 and the first protrusion 412 form a step-like structure.

[0054] The second section 42 includes a second body 421 and a second protrusion 422 . The second protrusion 422 is connected to one end of the second body 421 facing the first section 41 , and is located at a portion of the second body 421 close to the A-pillar inner panel 11 , that is, the first body 411 and the first protrusion 412 form a stepped structure.

[0055] The second protrusion 422 is superposed on the first protrusion 412, and the second protrusion 422 is engaged with the first protrusion 412, the second protrusion 422 abuts against the first body 411 in the extending direction of the first body 411, and the first protrusion 412 abuts against the second body 421 in the extending direction of the first body 411. In other words, the step-like structure of the first section 41 and the step-like structure of the second section 42 are meshed and matched with each other.

[0056] When the expansion sound insulation member 4 expands, the expanded first section 41 and the second section 42 can be reliably abutted together in the width direction of the vehicle and in the extension direction of the first main body 411, further reducing the risk of the first section 41 and the second section 42 being separated from each other, and reducing the risk of a gap being generated between the first section 41 and the second section 42, thereby effectively ensuring the sealing effect of the expansion sound insulation member 4 on the inner cavity and improving the reliability of the reinforcement bracket 30.

[0057] Reference Figure 3 , Figure 6 and Figure 7In some embodiments of the present invention, the second body 421 is engaged with the bracket skeleton 3. In this way, the bracket skeleton 3 can limit the second protrusion 422 through the second body 421, so that the second protrusion 422 can be reliably superimposed on the first protrusion 412, so that the second protrusion 422 is reliably engaged with the first protrusion 412, thereby effectively reducing the risk of the first section 41 and the second section 42 being separated from each other, reducing the risk of a gap between the first section 41 and the second section 42, effectively ensuring the sealing effect of the expansion sound insulation member 4 on the inner cavity, and improving the reliability of the reinforced bracket 30.

In this way, the connection between the second body 421 and the bracket skeleton 3 can be achieved. At the same time, the operator can observe whether the stop portion 3162 stops on the stop plate 43 through the through hole 423, which is convenient for the operator to clamp the second body 421 to the skeleton body 31.
