For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] like Figure 1 As shown, an exemplary embodiment of the present utility model provides a vehicle body 100. The vehicle body 100 can be applied to a vehicle, wherein the vehicle can be a fuel vehicle, an electric vehicle, a hybrid vehicle, etc. It should be noted that the vehicle can be a sedan, an SUV, an MPV or other suitable models.
[0041] The vehicle body 100 includes an A-pillar assembly 1 and a door sill 2. The extending direction from the interior of the vehicle to the exterior thereof is defined as a first direction X. Along the first direction X, the A-pillar assembly 1 includes a first plate 11, an A-pillar body 12, and a second plate 13 connected in sequence. The first plate 11 may be an A-pillar inner plate disposed on the inner side of the A-pillar body 12, i.e., on the side facing the interior of the vehicle. The second plate 13 may be an A-pillar outer plate disposed on the outer side of the A-pillar body 12, i.e., on the side facing the exterior of the vehicle.
[0042] Reference Figure 2 , Figure 3 Combined with Figure 7In the j-shaped area shown in , in one example, the first plate 11 and the A-pillar body 12 can be connected by spot welding, or by a combination of spot welding and structural adhesive. Specifically, the first plate 11 can be fixed to the A-pillar body 12 by spot welding, and the first plate 11 and the A-pillar body 12 can be sealed with structural adhesive at other places except the welding position to increase the structural connection strength between the first plate 11 and the A-pillar body 12, and at the same time, the structural adhesive is used for sealing. In a specific example, other positions between the first plate 11 and the A-pillar body 12 except the welding position can be sealed with double-pass structural adhesive to ensure the sealing effect between the first plate 11 and the A-pillar body 12.
[0043] The second plate 13 and the A-pillar body 12 can be connected by spot welding, or by a combination of spot welding and structural adhesive. Specifically, the second plate 13 can be fixed on the A-pillar body 12 by spot welding, and the second plate 13 and the A-pillar body 12 can be sealed by structural adhesive at other places except the welding position to increase the structural connection strength between the second plate 13 and the A-pillar body 12, and at the same time, the structural adhesive can be used for sealing. In a specific example, other positions between the second plate 13 and the A-pillar body 12 except the welding position can be sealed by double-pass structural adhesive to ensure the sealing effect between the second plate 13 and the A-pillar body 12.
[0044] Continue to refer to Figure 4 As shown, the extension direction from the top of the vehicle to the bottom thereof is defined as the second direction Y, that is, the first direction X and the second direction Y are arranged perpendicular to each other. The A-pillar body 12 includes a bottom end 121 arranged along the second direction Y. The door sill 2 is fixedly connected to the bottom end 121 of the A-pillar body 12, wherein the door sill 2 and the bottom end 121 of the A-pillar body 12 can be connected by existing vehicle connection methods such as spot welding, screws, rivets, etc.
[0045] The forward direction of the vehicle is defined as the third direction Z, that is, any two directions among the first direction X, the second direction Y and the third direction Z are perpendicular to each other. Along the third direction Z, the front side of the door sill 2 exceeds the lower front side m of the A-pillar body 12 by a predetermined distance. It should be noted that the lower front side m of the A-pillar body 12 is the side wall at the connection position between the door sill 2 and the door sill 2 and facing the third direction Z, that is, the lower front side m of the A-pillar body 12 is as shown in FIG. Figure 4 Shown in the dashed box.
[0046] In this example, the front side of the door sill 2 extends beyond the lower front side of the A-pillar body 12 by a predetermined distance m, which is beneficial for maintaining the structural integrity of the A-pillar assembly 1 of the vehicle when the vehicle slides, reducing the vehicle's dependence on the overall structure, thereby effectively improving the driver's safety.
[0047] It should be noted that if Figure 5 As shown in the f area, the connection method of the first plate 11 or the A-pillar body 12 or the second plate 13 with other front-end structures of the vehicle can be a spot welding and bonding connection method, for example, spot welding is used for fixed connection, and one or two layers of structural adhesive or sealant are applied to other connection positions or matching surfaces other than the spot welding positions for sealed connection, and a layer of adhesive layer such as PCV adhesive layer is applied to the outer edge area or staggered area at the corresponding connection position to form a reliable connection sealing structure, thereby effectively ensuring the structural strength and sealing effect of the connection between the A-pillar assembly 1 and other structural components of the vehicle.
[0048] like Figure 4 As shown, in some embodiments, the front side of the door sill 2 exceeds the lower front side m of the A-pillar body 12 by a predetermined distance of at least greater than or equal to 5 mm, that is, the lower front side m of the A-pillar body lags behind the front side of the door sill 2 by at least 5 mm, which is beneficial for the vehicle to effectively reduce the structural dependence on vehicle slippage in a 25% small offset collision with the highest risk of frontal collision, maintain the integrity of the A-pillar assembly 1, and thus effectively improve the driver's driving safety factor.
[0049] It should be noted that, in this example, the 25% offset frontal collision test on the driver's side is carried out under the condition that the vehicle collides head-on against a fixed rigid barrier at a speed of 64.4km / h±1km / h and an overlap rate of 25%±1%. Since the firewall and the A-pillar body 12 structure are close to the tire 4 of the vehicle, the front energy absorption and collapse distance of the A-pillar body 12 is insufficient. In adopting the sliding strategy, in order to reduce the dependence of the vehicle on its overall structure during sliding, the front side of the door sill 2 is set forward of the lower front side m of the A-pillar body 12, which can effectively reduce the bending of the side beam area of the A-pillar body 12 and the energy absorption of its lower part, thereby effectively maintaining the integrity of the overall structure of the A-pillar body 12, thereby improving the safety of the driver.
[0050] like Figure 4 As shown, in some embodiments, the A-pillar body 12 further includes a front end 122 disposed along the third direction Z. The vehicle body 100 includes a shock absorbing assembly 3 , which is connected to the front end 122 of the A-pillar body 12 .
[0051] In one example, if Figure 1 and Figure 2 The shock absorbing assembly 3 includes a shock absorbing tower 31 and a front longitudinal beam 32. The end of the front longitudinal beam 32 facing the third direction Z can be connected to other front end structures of the vehicle, such as a joint structure, etc. The end of the front longitudinal beam 32 facing away from the third direction Z is connected to the front end 122 of the A-pillar body 12.
[0052] The shock tower 31 is connected to the front end 122 of the A-pillar body and the front longitudinal beam 32 respectively. The connection process between the shock tower 31 and the front end 122 of the A-pillar body 12 at least includes a hot melt self-tapping process or a self-piercing riveting process. Figure 5 As shown in the g area, the shock absorber tower 31 can be fixedly connected to the front end 122 of the A-pillar body 12 by a hot-melt self-tapping process, or the shock absorber tower 31 can be fixedly connected to the front end 122 of the A-pillar body 12 by a self-piercing riveting process.
[0053] In a specific example, the shock tower 31 may be connected to the A-pillar body 12 , the first plate 11 , and the second plate 13 respectively by a hot-melt self-tapping process or a self-piercing riveting process to increase the structural strength of the connection between the shock tower 31 and the A-pillar assembly 1 .
[0054] The structural matching surface at the connection position between the shock tower 31 and the A-pillar body 12 is sealed by at least one layer of structural glue or sealant. Specifically, two layers of structural glue or sealant can be used to effectively ensure the connection sealing effect and anti-corrosion performance between the shock tower 31 and the A-pillar body 12.
[0055] At the same time, an adhesive layer is provided in the outer area of the connection position between the shock tower 31 and the A-pillar body 12. Specifically, a layer of PVC adhesive layer can be applied to the outer edge area or staggered area of the connection position between the shock tower 31 and the A-pillar body 12 to cooperate with the hot melt self-tapping process or the self-piercing riveting process to form a reliable connection and sealing structure between the shock tower 31 and the A-pillar assembly 1.
[0056] Reference Figure 5 As shown in the d height, wherein the d height is the longitudinal height of the portion of the front longitudinal beam 32 above the front tire 4 of the vehicle. Along the second direction Y, the d height may be 65 mm. The 65 mm height after full compression is beneficial for controlling the space from the front cover of the vehicle to the jumping direction of the front tire 4. A lower front cover is beneficial for maintaining the overall sporty style of the exterior of the vehicle.
[0057] Reference Figure 6 As shown in the e width, wherein the e width is the width of the portion of the front longitudinal beam 32 above the front tire 4 of the vehicle, and the e width may be 95 mm. In this example, by fully compressing the e width, it is beneficial to free up layout space for other components in the vehicle body, thereby ensuring the overall sporty style of the exterior of the vehicle.
[0058] like Figure 1 Combined with Figure 2 As shown, along the third direction Z, the front longitudinal beam 32 , the A-pillar body 12 and the door sill 2 enclose a receiving space, and the receiving space is used to receive the front tire 4 of the vehicle.
[0059] The vertical distance between the side of the A-pillar body 12 close to the front tire 4 and the tire center of the front tire 4 is a first distance a, and the vertical distance between the side of the A-pillar body 12 far from the front tire 4 and the tire center of the front tire 4 is a second distance b.
[0060] In one example, the first distance a is less than or equal to 300 mm, and the second distance b is less than or equal to 680 mm. When the length of the vehicle is the same, in this example, by constraining the first distance a and the second distance b, the A-pillar body 12 is moved forward, thereby increasing the operating space of the cab, thereby effectively improving the driver's driving experience.
[0061] In this example, by constraining the second distance b to be less than or equal to 300 mm, the height difference between the tire center of the front tire 4 of the vehicle and the large surface shape of the front cover fender in the vehicle height direction can be made to be about 617 mm, and the side beam space can be made to be about 50 mm high. By selecting a suitable casting structure, it is possible to reasonably arrange reinforcing ribs within the limited side beam space height, thereby achieving the performance requirements of the vehicle structure.
[0062] like Figure 2 As shown, in some embodiments, an expansion piece 5 is provided on the A-pillar body 12 and on the side facing the front tire, and the expansion piece 5 is connected to the A-pillar body 12 via a mounting bracket 6 .
[0063] A glue coating area h is provided at the connection position between the expansion piece 5, the mounting bracket 6 and the A-pillar body 12, that is, Figure 7 h area in the coating area, wherein the overflow glue design is adopted in the coating area h. In this example, by defining the expansion sheet 5 and the mounting bracket 6, and cooperating with the overflow glue design in the coating area h, a two-layer sealing connection structure is formed; at the same time, the mounting bracket 6 can effectively control the risk of sealing failure caused by the deflection of the expansion sheet 5 driven by the liquid during the electrophoresis process.
[0064] An exemplary embodiment of the present utility model provides a vehicle (not shown in the figure), which comprises the vehicle body in any of the above embodiments.
[0065] The vehicle includes but is not limited to components such as wheels, steering wheels, and power systems, and the vehicle may be a fuel vehicle, an electric vehicle, a hybrid vehicle, etc. It should be noted that the vehicle may be a sedan, an SUV, an MPV, or other suitable models.
[0066] In this example, along the forward direction of the vehicle, by lagging the lower front side of the A-pillar body in the A-pillar assembly 1 behind the front side of the threshold 2 by a predetermined distance c, it is beneficial to maintain the integrity of the A-pillar assembly structure of the vehicle when the vehicle slides, reduce the dependence of the vehicle on the overall structure, and effectively improve the safety factor of the driver. In addition, by using the constraints of the first distance a, the second distance b and other dimensions, the exterior shape of the vehicle body is moved forward and relatively close to the front tire 4, so that under the relationship of the downward pressure trend of the front cover of the vehicle, a vehicle is defined that reduces the risk of failure of the sliding strategy and improves the overall structural integrity of the A-pillar assembly during a small offset sliding expansion process. At the same time, by using the constraints of the dimensions of d height and e width, the width and height of the vehicle are compressed, and the space in the cab is released. With the multiple connection sealing structures in the f area, g area and h area, the risk of failure of the air tightness and water tightness of the vehicle structure is effectively reduced, and the performance requirements of the body design are guaranteed and improved.
[0067] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
