Description
Technical Field
[0001] The utility model relates to the technical field of vehicle parts, and in particular to a vehicle body pillar. Meanwhile, the utility model also relates to a vehicle using the above vehicle body pillar. Background Art
[0002] The body pillar is an important part of the automobile body structure, usually referring to the vertical or inclined rigid components that support the body frame. These pillars not only provide good structural strength, but also affect the overall safety, rigidity and driving stability of the vehicle.
[0003] Take the C-pillar as an example. The C-pillar is located between the rear windshield and the rear door. It is a pillar connecting the roof and the rear of the car body. Its main function is to support the roof and provide a certain degree of side collision protection.
[0004] The existing C-pillar is generally composed of a rear side window inner panel, an upper side beam reinforcement plate, a C-pillar reinforcement plate, and a side panel outer panel. A accommodating cavity is formed between the side panel outer panel and the rear side window inner panel. The upper side beam reinforcement plate and the C-pillar reinforcement plate are arranged in the accommodating cavity, and the upper side beam reinforcement plate and the C-pillar reinforcement plate are arranged up and down.
[0005] Due to the requirements of welding process reliability, four-layer welding is generally not allowed. Therefore, the upper side beam reinforcement plate and the C-pillar reinforcement plate cannot be welded or overlapped. There is a certain gap between the two in the vehicle height direction, that is, the reinforcement structure is interrupted in the vehicle height direction.
[0006] Since these two reinforcement plates are important components of the vehicle body frame, if they are only connected by two thin plates, the rear side window inner panel and the side panel outer panel, the connection stiffness will be weak, resulting in easy deformation of the vehicle body stiffness and modal conditions. How to strengthen the structure in this area has become a difficult point in design and development. Utility Model Content

[0047] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0048] Embodiment 1
[0049] This embodiment relates to a vehicle body pillar, which still adopts three-layer plate welding to achieve the continuity of the reinforcement structure in the vehicle height direction.
[0050] Based on the above design concept, an exemplary structure of the vehicle body pillar in the application state of this embodiment is as follows Figures 1 to 3 As shown, it generally includes a pillar outer panel, a pillar reinforcement plate 3 and a pillar inner panel, a receiving space for receiving the reinforcement plate is formed between the pillar inner panel and the pillar outer panel, the pillar reinforcement plate 3 is sandwiched between the pillar outer panel and the pillar inner panel, that is, the pillar reinforcement plate 3 is located in the receiving space, and the front side of the pillar reinforcement plate 3 forms a three-layer structure with the pillar outer panel and the pillar inner panel, and the rear side of the pillar reinforcement plate 3 also forms a three-layer structure with the pillar outer panel and the pillar inner panel, so that the front and rear sides of the vehicle body pillar are welded together through three-layer plates.
[0051] The vehicle body pillar of this embodiment is connected by welding the pillar reinforcement plate 3 to the pillar inner plate and the pillar outer plate. When the vehicle body pillar is subjected to a lateral impact, the pillar reinforcement plate 3 can effectively transfer the impact force from the pillar outer plate to the pillar inner plate, so that the pillar outer plate and the pillar inner plate jointly bear the impact force, which can improve the lateral impact resistance of the vehicle body pillar, thereby improving the application reliability of the vehicle body pillar.
[0052] In this embodiment, the vehicle body pillar may be, for example, an A-pillar, a B-pillar, a C-pillar 5 , etc. in the vehicle. For the convenience of description, and because the C-pillar 5 is located close to the rear quarter window 6 , it requires a higher structural strength. Therefore, the following embodiment is described by taking the C-pillar 5 as an example of the vehicle body pillar.

The C-pillar 5 adopts the structure of the vehicle body pillar of this embodiment, which can better improve the structural strength of the C-pillar 5 and is conducive to improving the side collision performance of the C-pillar 5 of the vehicle.
[0055] As a preferred embodiment, the length direction of the overlapping area 303 is arranged along the height direction of the vehicle, which is beneficial to improving the reinforcement effect of the overlapping area 303, so that the pillar reinforcement plate 3 can better achieve continuous reinforcement of the body pillar in the height direction of the vehicle.
[0056] As a preferred embodiment, the parts of the adjacent sub-reinforcement plates located at the front side of the overlapping area 303 are gap-fitted, which is conducive to preventing the adjacent sub-reinforcement plates from generating collision noise.

[0060] In the above structure, the connecting member is set as a bolt 401, and the bolt 401 can adopt an existing standard part to reduce the production cost. The nut 402 is pre-fixed on the side of the overlapping area 303 facing the outer plate of the column, and then the bolt 401 is passed through the connecting hole 3031 and screwed to the nut 402 using a tool, and the assembly method is relatively simple. In a preferred embodiment, the connecting member may also include a gasket, a spring washer, etc., which is sleeved on the bolt 401 to improve the reliability of the connection of the bolt 401.
[0061] It should be noted that, preferably, the number of the aforementioned clearance holes 201 is multiple, and the number of the clearance holes 201 corresponds to the number of the connecting pieces, so that the structural strength of the pillar inner plate, such as the rear side window inner plate 2 in this embodiment, is less affected. In addition, it is of course feasible to set the clearance hole 201 as one.

The formed reinforcement structures are complementary, which is beneficial to improving the reinforcement effect of the vehicle body pillar.
[0066] When assembling, Figure 2 and Figure 5 As shown, the upper side beam reinforcement plate 301 can be first welded to the side outer plate 1, and then Figure 3 and Figure 7 As shown, the C-pillar reinforcement plate 302 is welded to the rear side window inner plate 2, and then the two are buckled together.
