Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to an A-pillar structure and a vehicle comprising the A-pillar structure. Background Art
[0002] The A-pillar of a car is an important part of the car body, which mainly plays a supporting role and plays a role in appearance modification. The A-pillar of a car is located between the front door and the front windshield, and plays a structural supporting role. Generally, the A-pillar includes three layers in the cross section, namely the A-pillar inner panel, the A-pillar outer panel and the side panel outer panel, which constitute the A-pillar skeleton structure. The A-pillar inner panel, the A-pillar outer panel and the side panel outer panel are each formed by cold stamping sheet metal and welded together to form a double cavity form.
[0003] In addition to its safety performance, the A-pillar of a passenger car also has a lot of attention for its impact on the driver's field of vision and wind resistance. The impact of the A-pillar on the driver's field of vision can be measured by the A-pillar obstacle angle, see Figure 7 The A-pillar obstacle angle is related to the width of the A-pillar interior panel in the field of vision, which is usually difficult to reduce after the exterior shape is determined. In addition, the A-pillar obstacle angle is also closely related to the width of the black area of the windshield. The black area of the windshield is used to cover the installation area of the windshield and the A-pillar frame, which plays a decorative role. It can be seen that the A-pillar obstacle angle is affected by the above two aspects, and its angle is relatively large. At the same time, in order to reduce the wind resistance of the A-pillar, Figure 8 The A-pillar area usually requires the addition of a glass trim that is approximately parallel to the front windshield. At this time, one end of the front windshield will extend between the A-pillar frame and the glass trim to reduce wind resistance. However, the addition of the glass trim will increase the difficulty of matching, that is, the DTS (Dimensional Technical Specification) matching and adjustment of the glass trim and the side A-pillar is more difficult, which affects the NVH (Noise, Vibration, Harshness) performance of the vehicle.
[0004] Therefore, it is necessary to design an A-pillar structure and a vehicle to solve the problem of excessively large A-pillar obstacle angles and reduce wind resistance without affecting the NVH performance of passenger cars. Utility Model Content

[0033] The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations. The details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0034] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.
[0035] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.
[0036] See Figure 7 Kazumi Figure 8 For the existing vehicle A-pillar structure, see Figure 7 The A-pillar obstruction angle is related to the width of the A-pillar interior panel in the sight area, which is usually difficult to reduce after the exterior shape is determined. In addition, the A-pillar obstruction angle is also closely related to the width of the black area of the front windshield. The black area of the front windshield is used to cover the installation area of the front windshield and the A-pillar frame, playing a decorative role. Figure 8 In order to reduce the wind resistance of the A-pillar, the A-pillar area usually requires the addition of a glass trim that is approximately parallel to the front windshield. At this time, one end of the front windshield will extend between the A-pillar frame and the glass trim to reduce wind resistance. However, the addition of the glass trim will increase the matching difficulty, that is, the DTS matching and adjustment of the glass trim and the side A-pillar is more difficult, which affects the NVH performance of the vehicle.
[0037] In one embodiment of the present invention, see Figure 1 to Figure 3The utility model provides an A-pillar structure, comprising an A-pillar skeleton and an outer panel 2, wherein the A-pillar skeleton comprises an A-pillar inner panel 11 and an A-pillar outer panel 12, the A-pillar inner panel 11 and the A-pillar outer panel 12 are welded together on both sides, and the A-pillar skeleton is a hollow structure; the two welding places of the A-pillar inner panel 11 and the A-pillar outer panel 12 are respectively overlapping welding parts. The outer panel 2 comprises a connecting rib plate 21 and an outer panel 22, the connecting rib plate 21 and the outer panel 22 are buckled, and one end of the outer panel 22 close to the front windshield 3 is set as a straight portion 221 parallel to the front windshield 3; the outer panel 22 is connected to the A-pillar outer panel 12 through the connecting rib plate 21 to cover the middle part of the A-pillar outer panel 12 and its front blocking portion 123; one end of the front windshield 3 is inserted between the straight portion 221 of the outer panel 22 and the front blocking portion 123 of the A-pillar outer panel 12. The side of the outer trim 22 away from the straight portion 221 extends to the side window glass 4, and the side window glass 4 is connected to the side window portion of the A-pillar outer panel 12. The width of the straight portion 221 of the outer trim 22 is the same as the width of the insertion portion of the front windshield 3, which is 20 mm. The A-pillar interior trim 5 is used to shield the internal A-pillar skeleton structure, and its visual width is strongly related to the A-pillar obstacle angle. Therefore, the setting of the straight portion 221 of the outer trim 22 can shield the installation part of the front windshield 3 and the A-pillar skeleton, and play the same decorative effect as the original black area of the front windshield 3, cancel the setting of the black area of the front windshield 3 (usually the width of the black area is about 30 mm), reduce the A-pillar obstacle angle, and reduce it to 80% of the original obstacle angle; solve the problem of excessive A-pillar obstacle angle. The straight portion 221 reduces wind resistance and directly overlaps with the front windshield 3, with a short size chain and easy matching, and will not affect the NVH performance of the passenger car.
[0038] In one embodiment of the present invention, see Figure 2-3 The two sides of the outer trim 22 buckle inward toward the A-pillar outer panel 12 to form a first buckle portion 121 and a second buckle portion 122, and a groove is formed in the middle of the outer trim 22. The connecting rib 21 is arranged in the groove of the outer trim 22. The first buckle portion 121 extends close to the outer surface of the front windshield 3, and the second buckle portion 122 extends close to the outer surface of the A-pillar outer panel 12. The part of the A-pillar outer panel 12 close to the vehicle side window corresponds to the installation part of the side window glass 4. The installation part is covered with a glass trim strip 41. The glass trim strip 41 and the installation part are connected by a first rubber block 42. The first rubber block 42 extends to the second buckle portion 122 of the outer trim 22, so that the second buckle portion 122 and the installation part of the side window glass 4 are sealed and bonded through the rubber block 42. The front windshield 3 is inserted between the straight portion 221 of the outer panel 22 and the front blocking portion 123 of the A-pillar outer panel 12 as its plug-in portion. The plug-in portion of the front windshield 3 and the outer panel 22 are sealed and bonded by a second rubber block 31 .
[0039] In one embodiment of the present invention, see Figures 4 to 6, buckles 211 are provided at intervals along the length direction of the connecting rib plate 21, and buckle holes are provided on the outer panel 22 accordingly. The buckles 211 and the buckle holes correspond to each other and are provided in coordination, so that the connecting rib plate 21 and the outer panel 22 are buckled and connected together. Threaded holes 212 are provided on the connecting rib plate 21, and the threaded holes 212 are arranged alternately along the length direction of the connecting rib plate 21. The threaded holes 212 and the bolts 213 are installed in coordination with each other to fix the connecting rib plate 21 and the A-pillar outer panel 12; wherein, the installation directions of the two adjacent bolts 213 corresponding to the adjacent threaded holes 212 are opposite, and one of the bolts 213 is installed from the outside to the inside, and the other bolt 213 is installed from the inside to the outside. Since the threaded holes 212 are staggered along the length direction of the connecting rib plate 21, the bolts 213 are also staggered along the length direction of the connecting rib plate 21. One of the adjacent bolts 213 is installed from the outside to the inside and the other is installed from the inside to the outside. The connecting rib plate can be installed and fixed in a W-shape + alternating inside and outside. This installation and fixing method will make the relative installation area larger and reduce the installation failure rate. Therefore, the overall stability of the A-pillar structure is higher and the structural strength is greater.
[0040] In one embodiment of the utility model, a vehicle is included. The vehicle includes the A-pillar structure, the front windshield 3 and the side window glass 4 as described above. The A-pillar structure includes an A-pillar inner plate 11, an A-pillar outer plate 12 and an outer plate 2. The A-pillar inner plate 11 and the A-pillar outer plate 12 are welded together at both sides, and the A-pillar structure is a hollow structure. The outer plate 2 includes a connecting rib plate 21 and an outer decorative plate 22. The connecting rib plate 21 and the outer decorative plate 22 are buckled. The outer decorative plate 22 is close to the front windshield 3 and is set to be connected to the front windshield 3. The straight portion 221 is parallel to the windshield 3; the outer trim 22 is connected to the A-pillar outer panel 12 through the connecting rib plate 21 to cover the middle part of the A-pillar outer panel 12 and the front blocking portion 123 of the A-pillar outer panel 12; one end of the front windshield 3 is inserted between the straight portion 221 of the outer trim 22 and the front blocking portion 123 of the A-pillar outer panel 12, and the side of the outer trim 22 away from the straight portion 221 extends to the side window glass 4, and the side window glass 4 is connected to the side window portion of the A-pillar outer panel 12.
[0041] In summary, the A-pillar structure and vehicle of the utility model can reduce the A-pillar obstacle angle by eliminating the black area setting of the front windshield 3, which is reduced to about 80% of the original obstacle angle (such as Figure 7As shown, the original front windshield 3 is provided with a black area, which increases the A-pillar obstacle angle. Now the setting of the black area is cancelled, the front windshield 3 is completely visible to the outside world, and the A-pillar obstacle angle can be reduced); the straight portion 221 of the exterior panel 22 reduces the wind resistance and directly overlaps with the front windshield 3, with a short size chain and easy matching, thereby improving the NVH performance of the passenger car. At the same time, threaded holes 212 are provided on the connecting rib plate 21, and the threaded holes 212 are staggered along the length direction of the connecting rib plate 21. When the threaded holes 212 and the bolts are installed one by one, the W-shaped + inside and outside alternating installation and fixing are adopted, which also makes the overall stability of the A-pillar structure higher and the structural strength greater.
