Description

Technical Field

[0001] This utility model relates to the field of vehicle body structure technology, and in particular to a vehicle pillar. This utility model also relates to a vehicle equipped with the aforementioned vehicle pillar. Background Technology

[0002] Vehicle pillars, as one of the important components of the vehicle body, support the roof and are located between the windows and doors. Vehicle pillars are generally divided into A, B, and C pillars; depending on the model, some models also have a D pillar. Taking the A pillar as an example, the lower part of the A pillar is a critical protection position for the driver, making reinforcement of the lower A pillar particularly important.

[0003] In existing technology, the lower part of the A-pillar is mainly composed of a side reinforcement plate and an inner A-pillar panel that are fastened together to form a cavity. Traditionally, the structural strength of the lower A-pillar is enhanced by attaching or welding reinforcement plates or supplementary plates to the side reinforcement plate and the inner A-pillar panel. However, this method still has certain limitations; the collision response capability of the A-pillar needs further improvement in the event of a vehicle collision. Utility Model Content

[0004] In view of this, the present invention aims to provide a vehicle pillar that improves the structural strength of the pillar while facilitating the dispersion of collision forces.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A vehicle pillar includes a pillar body and a reinforcing member disposed within a cavity of the pillar body;

[0007] The reinforcing member extends along the front-rear direction of the vehicle, and the front and rear parts of the reinforcing member are respectively connected to the two opposite sides of the cavity;

[0008] The reinforcing member is vertically arranged in the cavity and extends from front to back along the front-to-back direction of the vehicle. The size of the reinforcing member gradually increases in the vertical direction of the vehicle.

[0009] Furthermore, the column body includes an outer column plate and an inner column plate that enclose the cavity, with the front and rear portions of the outer column plate and the inner column plate overlapping and connected respectively; the reinforcing member includes a reinforcing plate vertically arranged in the cavity, with the front and rear portions of the reinforcing plate respectively inserted between the overlapping outer column plate and the inner column plate, and connected to both the outer column plate and the inner column plate.

[0010] Furthermore, in the left-right direction of the vehicle, the reinforcing plate is arranged close to the middle of the outer plate and the inner plate of the pillar; and / or, in the up-down direction of the vehicle, the front part of the reinforcing plate is continuously arranged in the area between the outer plate and the inner plate of the pillar.

[0011] Furthermore, a first adhesive is provided between the front part of the reinforcing plate and the inner plate of the column to bond the reinforcing plate and the inner plate of the column together; and / or, a second adhesive is provided between the front part of the reinforcing plate and the outer plate of the column to bond the reinforcing plate and the outer plate of the column together.

[0012] Furthermore, in the front-rear direction of the vehicle, the outer edge of the pillar, the inner edge of the pillar, and the reinforcing plate are staggered.

[0013] Furthermore, the area where the rear of the reinforcing plate is inserted between the outer plate and the inner plate of the column is provided with multiple clearance grooves, and the multiple clearance grooves are arranged at intervals along the vertical direction of the whole vehicle.

[0014] The outer plate of the column and / or the inner plate of the column are provided with protrusions, and the protrusions are correspondingly provided with the clearance grooves, and each protrusion is embedded in the corresponding clearance groove.

[0015] Furthermore, the reinforcing plate has a recessed portion in the middle that is recessed to one side; the depth of the recessed portion gradually decreases from front to back along the front-rear direction of the vehicle; and / or, the recessed portion is provided with reinforcing ribs.

[0016] Furthermore, the recessed portion is provided with a positioning portion for positioning the reinforcing plate within the cavity; and / or, the recessed portion is provided with a through hole for external tools to pass through.

[0017] Furthermore, the vehicle pillar is an A-pillar, and in the vertical direction of the entire vehicle, the reinforcing member is located at the middle position of the lower part of the A-pillar.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] (1) The vehicle pillar described in this utility model provides a reinforcing member in the cavity of the pillar body, which is arranged vertically in the cavity. The front and rear parts of the reinforcing member are connected to the two opposite sides of the cavity, which can support the cavity and improve the structural strength of the cavity. Furthermore, from front to back in the front-to-back direction of the vehicle, the size of the reinforcing member in the vertical direction of the vehicle gradually increases. That is, the size of the reinforcing member in the XZ plane of the vehicle gradually increases from the front to the rear. This allows the impact force received at the front to be transmitted to the rear in a dispersed manner, which is beneficial to disperse the impact force. Thus, while improving the structural strength of the pillar, it is also beneficial to disperse the impact force and improve the impact performance of the pillar.

[0020] (2) The reinforcing member adopts a vertically arranged reinforcing plate in the cavity, so that the front and rear parts of the reinforcing plate are respectively sandwiched between the corresponding overlapping parts of the inner plate and the outer plate of the column, and are welded to both the outer plate and the inner plate of the column. This structure can form three force transmission paths from front to back along the outer plate, the reinforcing plate and the inner plate of the column body, which is conducive to improving the transmission of impact force. It can also strengthen the welding position to avoid tearing of the weld point at this position and improve the reliability of use.

[0021] (3) In the left-right direction of the vehicle, by arranging the reinforcing plate close to the middle position of the outer and inner plates of the pillar, the force transmission path can be further optimized, which is conducive to further improving the transmission of collision force. The front part of the reinforcing plate is continuously arranged in the area welded to the outer and inner plates of the pillar, so that the front part of the reinforcing plate is more closely fitted to the outer and inner plates of the pillar, thereby increasing the front bearing area of ​​the reinforcing plate and better bearing the front force.

[0022] (4) A first adhesive is provided between the front part of the reinforcing plate and the inner plate of the upright plate. This optimizes the overlap between the front part of the reinforcing plate and the inner plate of the upright plate from a welded joint to a large-area joint, which enhances the connection strength between the reinforcing plate and the inner plate of the upright plate and also seals the mating surfaces. Similarly, a second adhesive is provided between the front part of the reinforcing plate and the outer plate of the upright plate. This optimizes the overlap between the front part of the reinforcing plate and the inner plate of the upright plate from a welded joint to a large-area joint, which also enhances the connection strength between the reinforcing plate and the inner plate of the upright plate and also seals the mating surfaces. Moreover, the use of both the first and second adhesives further enhances the connection strength between the reinforcing plate and the inner and outer plates of the upright plate and also further seals the surfaces.

[0023] (5) In the front-rear direction of the whole vehicle, the outer edge of the pillar, the inner edge of the pillar and the reinforcing plate are staggered. This design is to ensure that the adhesive can cover the three layers of sheet metal for sealing during the application of the first adhesive and the second adhesive, which can effectively avoid poor sealing and also avoid the problem of adhesive cracking caused by excessive height difference at the three welding positions.

[0024] (6) Multiple clearance slots are provided at intervals along the vertical direction of the vehicle at the rear of the reinforcing plate, and the multiple clearance slots can cooperate with the protrusions on the outer plate or inner plate of the pillar. This allows for welding edge clearance on the inner plate or outer plate of the pillar, avoiding the formation of four layers of weld between the reinforcing plate and the surrounding components, which would affect the welding quality.

[0025] (7) A recess is provided in the middle of the reinforcing plate, such that the depth of the recess gradually decreases from front to back in the longitudinal direction of the vehicle, that is, the recess is deeper in the front and shallower in the back. In the event of a collision, if the welded edge at the front is crushed and deformed, the recess can directly abut against the inner plate of the pillar and participate in the force transmission, preventing the cavity at this position from continuing to deform. Reinforcing ribs are provided on the recess, which can improve the overall rigidity of the reinforcing plate, improve its stress performance, and also prevent the springback of the concave surface during the stamping process of the reinforcing plate.

[0026] (8) The positioning part provided on the recess is conducive to the positioning of the reinforcing plate in the cavity and ensures the accuracy of the reinforcing plate installation position. The through hole provided on the recess facilitates the passage of external tools such as welding clamps, thereby helping to ensure welding quality and smooth withdrawal of welding clamps.

[0027] (9) The reinforcement is placed in the middle of the lower part of the A-pillar. Through safety collision and durability model analysis, it was found that this position is the weakest point of the lower part of the A-pillar. At this time, placing the reinforcement in this position can not only improve the overall structural strength of the lower part of the A-pillar, but also improve the torsional strength of the lower part of the A-pillar.

[0028] Another objective of this utility model is to provide a vehicle equipped with vehicle pillars as described above.

[0029] The vehicle of this invention, by employing the aforementioned vehicle pillar, allows the impact force received at the front to be transmitted rearward in a dispersed manner. This facilitates the dispersion of impact force, not only improving the structural strength of the pillar but also enhancing its load-bearing capacity, thereby improving the overall vehicle's collision performance.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Example 1

[0049] This embodiment relates to a vehicle pillar that can improve the structural strength of the pillar while facilitating the dispersion of collision forces, thereby enhancing the pillar's collision performance.

[0050] Vehicle pillars, as one of the important components of the vehicle body, support the roof and are located between the windows and doors. Vehicle pillars are generally divided into A, B, and C pillars, and some models also have a D pillar. Taking the A pillar as an example, the lower part of the A pillar is a critical protection position for the driver, making reinforcement of the lower part of the A pillar particularly important.

[0051] In existing technology, the lower part of the A-pillar is mainly composed of a side reinforcement plate and an inner A-pillar panel that are fastened together to form a cavity. In traditional structures, the structural strength of the lower A-pillar is enhanced by attaching or welding reinforcement plates or supplementary plates to the side reinforcement plate and the inner A-pillar panel. Typically, the reinforcement plates or supplementary plates are flat, U-shaped, or box-shaped, with overlapping edges on their circumference. These overlapping edges are attached to the side reinforcement plate or the inner A-pillar panel and then welded to fix them in place. While this structural form can improve the structural strength of the lower A-pillar to some extent, its collision resistance capability in the event of a vehicle collision needs further improvement.

[0052] Therefore, this embodiment addresses the shortcomings of the prior art by proposing a new vehicle pillar, and in its overall structure, as follows: Figures 1 to 3 As shown, the vehicle pillar in this embodiment includes a pillar body and a reinforcing member disposed in the cavity of the pillar body.

[0053] The reinforcing member extends along the longitudinal direction of the vehicle, and its front part 31 and rear part 32 are connected to the two opposite sides of the cavity, respectively. At the same time, the reinforcing member is vertically arranged in the cavity, and its size gradually increases from front to back along the longitudinal direction of the vehicle.

[0054] In this structure, as described above, vertically arranged reinforcing members are installed within the cavity of the pillar body. The front part 31 and the rear part 32 of the reinforcing members are connected to the two opposite sides of the cavity, respectively. This provides support within the cavity and enhances the structural strength of the cavity. Furthermore, from front to rear in the vehicle's longitudinal direction, the dimensions of the reinforcing members gradually increase in the vertical direction of the vehicle. That is, the dimensions of the front part 31 to the rear part 32 of the reinforcing members are gradually increased in the XZ plane of the vehicle. This allows the impact force received by the front part 31 to be transmitted rearward in a dispersed manner, which is beneficial for dispersing the impact force. Thus, while improving the structural strength of the pillar, it also facilitates the dispersion of the impact force, thereby improving the pillar's impact performance.

[0055] Based on the above overall structure, specifically, the column body of this embodiment includes an outer column plate 1 and an inner column plate 2 that enclose the cavity. The front and rear parts of the outer column plate 1 and the inner column plate 2 are correspondingly overlapped and connected. In specific applications, the reinforcing member of this embodiment can be applied not only to the A-pillar 10, but also to the B-pillar, C-pillar, and D-pillar.

[0056] This embodiment uses the A-pillar 10 as an example for detailed explanation. In terms of overall structure, the A-pillar 10 typically includes a lower A-pillar 22 extending along the vertical direction of the vehicle, and an upper A-pillar 11 connected to the lower A-pillar 22. Along the front-to-back direction of the vehicle, the upper A-pillar 11 gradually slopes upward. In this embodiment, the reinforcing member is specifically disposed in the structure of the lower A-pillar 22.

[0057] The lower part 22 of the A-pillar is mainly composed of a side panel reinforcement plate and an inner A-pillar panel that are fastened together, forming a cavity between the side panel reinforcement plate and the inner A-pillar panel. The aforementioned outer pillar panel 1 is the portion of the side panel reinforcement plate corresponding to the A-pillar location, and the inner pillar panel 2 is the inner A-pillar panel. In this embodiment, to improve the structural strength of the vehicle body side panel, a side panel reinforcement plate 101 is welded to the inner side of the side panel reinforcement plate, and an outer side panel 102 is also welded to the outer side of the side panel reinforcement plate. Furthermore, to improve the structural strength of the inner A-pillar panel, in this embodiment, an inner A-pillar panel reinforcement plate 201 is also welded to the outer side of the inner A-pillar panel.

[0058] In a preferred embodiment, the reinforcing member includes a reinforcing plate 3 vertically arranged within the cavity. The front portion 31 and the rear portion 32 of the reinforcing plate 3 are respectively inserted between the overlapping outer plate 1 and the inner plate 2 of the column, and are welded to both the outer plate 1 and the inner plate 2. That is, the front portion 31 of the reinforcing plate 3 is sandwiched between the front portions of the outer plate 1 and the inner plate 2 of the column, and is welded to both. The rear portion 32 of the reinforcing plate 3 is sandwiched between the rear portions of the outer plate 1 and the inner plate 2 of the column, and is welded to both.

[0059] At this point, the reinforcing member adopts a vertically arranged reinforcing plate 3 in the cavity, so that the front part 31 and the rear part 32 of the reinforcing plate 3 are respectively sandwiched between the corresponding overlapping parts of the inner plate 2 and the outer plate 1 of the column, and are welded to both the outer plate 1 and the inner plate 2 of the column. Compared with the traditional structure with a U-shaped reinforcing plate 3 or a box-shaped reinforcing plate 3, this structure provides a more direct and effective way to strengthen the welding position of the A-pillar, which can avoid the tearing of the weld point and improve the reliability of use. Moreover, it can form three force transmission paths from front to back along the outer plate 1, the reinforcing plate 3 and the inner plate 2 of the column body with the reinforcing plate 3, which is conducive to improving the transmission of collision force.

[0060] In this embodiment, by Figure 3 Combination Figures 6 to 8 As shown, along the front-to-back direction of the vehicle, the size of the front part 31 to the rear part 32 of the reinforcing plate 3 gradually increases, forming a structure that is narrow at the front and wide at the rear. This design can smoothly transfer the impact force received by the front part 31 to the rear when a collision occurs, and transfer the impact force received by the smaller area of ​​the front part 31 to the larger area of ​​the rear part 32, thereby dispersing the force transmission and improving the force-bearing capacity of the reinforcing plate 3.

[0061] In this embodiment, based on the narrow rear-wide structure formed by the reinforcing plate 3, the upper edge of the reinforcing plate 3 gradually slopes upward from front to rear along the front-rear direction of the vehicle, and the lower edge of the reinforcing plate 3 gradually slopes downward. In specific implementation, the angle between the upper edge and the lower edge of the reinforcing plate 3 is approximately 10°, which can more evenly transfer the impact force received by the front part 31 to the rear, further improving the impact force dispersion effect.

[0062] In this embodiment, the projection on the XY plane of the whole vehicle shows that both the outer column panel 1 and the inner column panel 2 have a U-shaped structure and both have connecting flanges arranged at the front and rear. The outer column panel 1 and the inner column panel 2 are fastened together, and the corresponding connecting flanges are welded together. A cavity is formed between the outer column panel 1 and the inner column panel 2.

[0063] As a further preferred embodiment, such as Figure 2As shown, in this embodiment, in the left-right direction of the vehicle, the reinforcing plate 3 is arranged close to the middle of the outer pillar plate 1 and the inner pillar plate 2. Specifically, in the left-right direction of the vehicle, the reinforcing plate 3 is arranged close to the middle of the side wall reinforcing plate and the inner A-pillar plate. At this time, the three force transmission paths formed by the outer pillar plate 1, the reinforcing plate 3 and the inner pillar plate 2 are further optimized, thereby further facilitating the transmission of collision force.

[0064] Based on this, as a further preferred implementation method, such as Figure 3 As shown, in this embodiment, the reinforcing member, i.e., the reinforcing plate 3, is located in the middle of the lower part 22 of the A-pillar 10 in the vertical direction of the entire vehicle. Through safety collision and durability model analysis, it was found that the middle position of the lower part 22 of the A-pillar is the weakest point in the overall vertical direction of the A-pillar. Therefore, placing the reinforcing member in the middle position of the lower part 22 not only improves the overall structural strength of the lower part 22 but also enhances its torsional strength.

[0065] It is worth mentioning that, in addition to being arranged in the middle position of the outer pillar panel 1 and the inner pillar panel 2 in the left-right direction of the whole vehicle, and in the middle position of the lower part 22 of the A-pillar in the up-down direction of the whole vehicle, the reinforcing plate 3 can also be arranged only in the middle position of the outer pillar panel 1 and the inner pillar panel 2 in the left-right direction of the whole vehicle, or only in the middle position of the lower part 22 of the A-pillar in the up-down direction of the whole vehicle. However, in terms of ensuring structural strength, the degree of dispersion of collision force and torsional strength, it is not as effective as the above-mentioned arrangement in which it is centered in both the left-right and up-down directions of the whole vehicle.

[0066] Reference Figure 3 and Figure 4 As shown in the preferred embodiment, in this embodiment, the front part 31 of the reinforcing plate 3 is continuously arranged in the area between the outer plate 1 and the inner plate 2 of the pillar in the vertical direction of the vehicle. That is, the front part 31 of the reinforcing plate 3 is relatively neat relative to the structure with notches or slots, which can increase the contact area between the reinforcing plate 3 and the outer plate 1 and the inner plate 2 of the pillar, ensuring that the front part 31 of the reinforcing plate 3 is closely fitted to the outer plate 1 and the inner plate 2 of the pillar, thereby increasing the stress-bearing area of ​​the front part 31 of the reinforcing plate 3 and better bearing the stress of the front part 31.

[0067] In this embodiment, a first adhesive is provided between the front part 31 of the reinforcing plate 3 and the inner plate 2 of the column to bond the reinforcing plate 3 and the inner plate 2 of the column together. The first adhesive can optimize the connection between the front part 31 of the reinforcing plate 3 and the inner plate of the column from a welded point connection to a large surface connection, which can enhance the connection strength between the reinforcing plate 3 and the inner plate 2 of the column, and can also seal the mating surface of the two.

[0068] Furthermore, in this embodiment, a second adhesive is also provided between the front part 31 of the reinforcing plate 3 and the outer plate 1 of the column to bond the reinforcing plate 3 and the outer plate 1 of the column together. This can optimize the connection between the front part 31 of the reinforcing plate 3 and the inner plate of the column from a welded point connection to a large surface connection, enhance the connection strength between the reinforcing plate 3 and the inner plate 2 of the column, and also seal the mating surfaces of the two.

[0069] At this point, simultaneously applying both the first and second adhesives further enhances the connection strength between the reinforcing plate 3 and the inner plate 2 and outer plate 1 of the column, while also providing a better seal. Furthermore, it is understandable that, in addition to applying both the first and second adhesives, it is also feasible to apply the first adhesive only between the front part 31 of the reinforcing plate 3 and the inner plate, or only between the front part 31 of the reinforcing plate 3 and the outer plate 1 of the column.

[0070] In specific implementation, the first adhesive and the second adhesive are preferably spot welding structural adhesives. And in some feasible embodiments, combined with... Figure 7 As shown, in this embodiment, adhesive application lines 37 are machined on the front part 31 of the reinforcing plate 3, and the starting position of the adhesive application lines 37 extends to the upper and lower edges of the reinforcing plate 3. Furthermore, the upper and lower edges of the reinforcing plate 3 must be coated with adhesive. This design ensures that when the spot welding structural adhesive is squeezed, it can overflow in both upward and downward directions and fill the rounded transition area near the contact point between the inner plate of the A-pillar and the reinforcing plate 3. This allows the overflowing spot welding structural adhesive to seal the non-contact areas.

[0071] It should be noted that providing adhesive application lines 37 on the front part 31 of the reinforcing plate 3 increases the contact area between the reinforcing plate 3 and the inner A-pillar panel, and between the reinforcing plate 3 and the side panel reinforcing plate, making the adhesive layer formed after curing more robust. It should also be noted that adhesive application lines 37 can be provided on both sides of the front part 31 of the reinforcing plate 3, or on the side panel reinforcing plate and the inner A-pillar panel, to ensure effective adhesive application between the front part 31 of the reinforcing plate 3 and the side panel reinforcing plate, and between the front part 31 of the reinforcing plate 3 and the inner A-pillar panel.

[0072] It is also worth noting that in this embodiment, the front weld position of the side reinforcement plate and the inner A-pillar plate is the boundary between the exterior and interior dry areas of the vehicle. At this time, spot welding structural adhesive is applied between the front part 31 of the reinforcement 3 and the front part of the side reinforcement plate, as well as between the reinforcement 3 and the front part of the inner A-pillar plate. This can also provide a good sealing effect on the bonding surface between the front part 31 of the reinforcement 3 and the side reinforcement plate and the inner A-pillar plate.

[0073] As a further preferred embodiment, refer to Figure 4As shown, in this embodiment, the front edges 31 of the outer pillar panel 1, inner pillar panel 2, and reinforcing plate 3 are staggered in the front-rear direction of the vehicle. That is, the front edges 31 of the side panel reinforcing plate, A-pillar inner panel, and reinforcing plate 3 are also staggered. This design ensures that during the application of the first and second adhesives, the adhesive can simultaneously cover and seal these three layers of sheet metal, effectively preventing poor sealing. It also avoids adhesive cracking caused by excessive height differences at the weld points of the three layers.

[0074] In specific implementation, it will still refer to Figure 4 As shown, in the longitudinal direction of the vehicle, the edge of the front part 31 of the reinforcing plate 3 protrudes forward relative to the edge of the outer panel 1 of the pillar, i.e., the edge of the side wall reinforcing plate, with a protrusion distance L1 between 2mm and 4mm, for example, 3mm. Furthermore, the edge of the inner A-pillar panel protrudes forward relative to the edge of the front part 31 of the reinforcing plate 3, with a protrusion distance L2 between 4mm and 6mm, for example, 5mm. This further ensures that during the application of the spot welding structural adhesive, the adhesive can simultaneously cover the three layers: the side wall reinforcing plate, the front part 31 of the reinforcing plate 3, and the inner A-pillar panel, further guaranteeing the sealing effect.

[0075] In this embodiment, multiple clearance grooves 302 are provided in the area between the rear part 32 of the reinforcing plate 3 and the outer plate 1 and inner plate 2 of the pillar. The multiple clearance grooves 302 are arranged at intervals along the vertical direction of the vehicle. At least one of the outer plate 1 and the inner plate 2 of the pillar has a protrusion 100, which is correspondingly provided with the clearance groove 302. Each protrusion 100 is embedded in the corresponding clearance groove 302. With this arrangement, when welding the reinforcing plate 3, the welding edge on the inner plate 2 or the outer plate 1 of the pillar can be avoided, preventing the rear part 32 of the reinforcing plate 3 from forming a four-layer weld with the side reinforcing plate, the outer plate 102 of the side, and the inner plate of the A-pillar, which would affect the welding quality.

[0076] Reference Figure 3 ,as well as Figures 5 to 7 As shown, in this embodiment, a plurality of protrusions 100 are provided on the inner A-pillar panel at intervals along the vertical direction of the vehicle. The portion between two adjacent protrusions 100 forms a welding edge that is welded to the outer side panel 102. The connecting flange between the outer side panel 102 and the inner A-pillar panel is planar. The outer side panel 102 and the inner A-pillar panel are welded together through the welding edge.

[0077] The rear part 32 of the reinforcing plate 3 forms multiple clearance grooves 302 arranged at intervals along the vertical direction of the vehicle. The portion between two adjacent clearance grooves 302 forms a sawtooth 301 overlapping structure. In specific implementation, the multiple clearance grooves 302 are arranged one-to-one with multiple protrusions 100, and each protrusion 100 is embedded in the corresponding clearance groove 302. Through the overlapping structure of the sawtooth 301, a three-layer weld is formed with the side wall reinforcing plate and the inner A-pillar panel. At the same time, a three-layer weld is also formed between the side wall reinforcing plate and the outer side wall panel 102 and the inner A-pillar panel, thereby ensuring better welding quality.

[0078] In this embodiment, since the side wall reinforcement plate and reinforcement plate 3 are thicker than the inner A-pillar panel, to ensure the welding quality between reinforcement plate 3 and the side wall reinforcement plate, refer to... Figure 7 As shown, the center width D1 of each sawtooth 301 is preferably designed to be greater than 15mm. Furthermore, the included angle α between the edges of two adjacent sawtooths 301 can be set between 80° and 120°, preferably 120°. And, the center width of the clearance groove 302, i.e. Figure 7 The spacing D2 between adjacent serrations 301 shown is preferably set to 22mm. This allows space to be reserved so that a three-layer weld can be formed between the inner A-pillar panel, the outer side panel 102, and the side reinforcement plate. It also avoids long distances without weld points and ensures welding quality.

[0079] It is worth mentioning here that the relevant dimensions of the clearance groove 302, such as the distance D2 between adjacent serrations 301 and the included angle α, can be designed according to the dimensions of the protrusion 100 formed on the side reinforcement plate, so as to ensure that the protrusion 100 can be embedded in the corresponding clearance groove 302.

[0080] In this embodiment, as a preferred embodiment, refer to Figures 6 to 9 As shown, a recessed portion 33 is provided in the middle of the reinforcing plate 3, and the depth of the recessed portion 33 gradually decreases from front to back along the longitudinal direction of the vehicle. That is, as... Figure 8 As shown, the recessed portion 33 is deeper at the front and shallower at the back. Figure 8 The dotted line in the diagram indicates the location of the rear part 32 of the recessed portion 33. In this structural design, if the welded edge of the front part 31 is crushed and deformed during a collision, the recessed portion 33 can directly abut against the inner plate 2 of the column and participate in force transmission, preventing the cavity at this location from continuing to deform.

[0081] Also preferably, a reinforcing rib 34 is provided on the recessed portion 33. Specifically, the recessed portion 33 is recessed towards the side of the inner plate of the A-pillar, and the reinforcing rib 34 protrudes towards the side away from the inner plate of the A-pillar, so that the cross-section of the reinforcing plate 3 is as follows: Figure 9The bow-shaped structure shown in the figure can improve the overall rigidity of the reinforcing plate 3, enhance its stress performance, and prevent the springback of the concave surface during the stamping process of the reinforcing plate 3.

[0082] Furthermore, preferably, the reinforcing rib 34 extends in a long strip along the front-rear direction of the vehicle, and in specific implementation, the height of the reinforcing rib 34, that is, the dimension of the reinforcing rib 34 in the width direction of the vehicle, can be set between 3mm and 5mm. This setting can further improve the overall rigidity of the reinforcing plate 3, improve the stress performance, and also further prevent the rebound of the concave surface.

[0083] In addition, in this embodiment, reference is made to Figure 6 and Figure 7 and combined Figure 3 As shown, a positioning part 35 is provided on the recessed part 33 for positioning the reinforcing plate 3 in the cavity. At this time, the setting of the positioning part 35 is beneficial to the positioning of the reinforcing plate 3 in the cavity and ensures the accuracy of the installation position of the reinforcing plate 3.

[0084] Specifically, the positioning part 35 includes positioning holes formed on the recessed part 33, with two positioning holes arranged at intervals. The positioning part 35 adopts a positioning hole structure, which facilitates its fabrication and also facilitates the positioning operation of the reinforcing plate 3. Furthermore, in a specific implementation, positioning posts are provided on the outer plate 1 of the pillar or on the inner plate 2 of the pillar at positions corresponding to the positioning holes. Through the insertion and engagement of the positioning posts with the positioning holes, the reinforcing plate 3 is positioned on the outer plate 1 or the inner plate 2 of the pillar. In this embodiment, preferably, the reinforcing plate 3 is positioned on the outer plate 1 of the pillar through the insertion and engagement between the positioning holes and the positioning posts on the outer plate 1, i.e., on the side panel reinforcing plate. This avoids obstructing many weld points, improves welding quality, and thus enhances the structural strength of the vehicle body side panel.

[0085] It is worth noting that, in addition to using positioning holes, the positioning part 35 in this embodiment can also use positioning posts, that is, positioning posts are formed on the recessed part 33. By cooperating with the positioning holes provided on the outer plate 1 or inner plate 2 of the column, the positioning of the reinforcing plate 3 on the outer plate 1 or inner plate 2 of the column can also be realized.

[0086] Furthermore, in this embodiment, a through hole 36 for external tools to pass through is also provided on the recessed portion 33. The through hole 36 facilitates the passage of external tools, such as welding guns, thereby ensuring welding quality and smooth withdrawal of the welding guns. In specific implementation, the through hole 36 is arranged between the two positioning holes. This arrangement facilitates welding operations on obscured weld points during the assembly of the reinforcing plate 3 and the side panel assembly, facilitates the smooth withdrawal of the welding gun, and ensures the welding quality of obscured weld points.

[0087] Because there are too many welding points when the A-pillar inner panel is assembled with the lower body, welding the reinforcing component along with the A-pillar inner panel assembly would obscure many of these weld points, resulting in long stretches without weld points and affecting vehicle performance. To solve this problem, in this embodiment, during the actual assembly of the pillar, the side panel reinforcing plate, side panel reinforcing plate supplement, hinge reinforcing plate, and lower hinge reinforcing plate are first assembled into a side panel assembly, and then the A-pillar inner panel, i.e., the A-pillar inner panel reinforcing plate, is assembled into an A-pillar inner panel assembly. Then, the reinforcing plate 3 is welded to the side panel assembly, and then assembled with the A-pillar inner panel assembly to form a side panel assembly. Finally, it is welded to the floor along with the side panel assembly. By welding the reinforcing component to the side panel assembly first, the problem of many weld points being obscured and long stretches without weld points affecting vehicle performance can be avoided, thus ensuring welding quality and contributing to maintaining vehicle performance.

[0088] In this embodiment, the vehicle pillar features a vertically arranged reinforcing member within the pillar body cavity, with its front portion 31 and rear portion 32 connected to opposite sides of the cavity. This not only provides support within the cavity, enhancing its structural strength, but also, thanks to the reinforcing member's narrower front and wider rear design, disperses the impact force received by the front portion 31 rearward, thus improving the pillar's impact performance while simultaneously increasing its structural strength.

[0089] Example 2

[0090] This embodiment relates to a vehicle, which is equipped with a vehicle pillar as described in Embodiment 1.

[0091] In this embodiment, the vehicle uses the vehicle pillar of Embodiment 1, which allows the impact force on the front 31 to be transmitted rearward in a dispersed manner. This helps to disperse the impact force, not only improving the structural strength of the pillar but also dispersing the impact force and enhancing the pillar's load-bearing capacity, thereby improving the overall vehicle's collision performance.

[0092] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
