[0033] The first embodiment of the utility model provides a vehicle roof structure, such as Figure 1 and Figure 2 As shown, the vehicle roof structure includes a roof outer panel 1 and a roof inner panel 2, a reinforcing tube 3 and a reinforcing rib assembly are connected between the roof outer panel 1 and the roof inner panel 2, the reinforcing tube 3 is arranged at the front of the roof, and extends outside the roof to be connected to the vehicle A-pillar 100, the reinforcing rib assembly includes a first reinforcing rib assembly 4 and a second reinforcing rib assembly 5 which are arranged in sequence along the length direction of the roof, one end of the first reinforcing rib assembly 4 is connected to the reinforcing tube 3, and the other end of the first reinforcing rib assembly 4 is connected to the second reinforcing rib assembly 5, and the shapes of the first reinforcing rib assembly 4 and the second reinforcing rib assembly 5 are different.
[0034] The vehicle roof is configured as a double-layer plate structure consisting of a roof outer panel 1 and a roof inner panel 2, which has higher strength than a structure having only one layer of plate. The roof outer panel 1 is arranged at the top, and the roof inner panel 2 is arranged at the bottom. An installation cavity is formed between the roof outer panel 1 and the roof inner panel 2, and the installation cavity is filled with a reinforcing tube 3, which further improves the structural strength of the front area of the vehicle roof. The reinforcing tube 3 is arranged at the front of the roof, and both ends of the reinforcing tube 3 extend to connect with the vehicle A-pillar 100 respectively. The reinforcing tube 3 and the vehicle A-pillar 100 form a continuously arranged reinforcing structure, which is beneficial to improving the structural strength of the area near the vehicle A-pillar 100.
[0035] A reinforcing rib assembly is provided on the outer side of the roof inner panel 2 (the side facing the roof outer panel 1), and the reinforcing rib assembly is located on the rear side of the reinforcing tube 3 to improve the structural strength of the rear area of the vehicle roof. The reinforcing tube 3 is connected to the first reinforcing rib assembly 4 in the reinforcing rib assembly to form an integral reinforcement structure to strengthen the vehicle roof.
[0036] The first reinforcing rib assembly 4 is located in the middle of the vehicle roof, and the second reinforcing rib assembly 5 is located in the rear of the vehicle roof. Different regions of the roof can be reinforced differently to meet different reinforcement requirements of different regions of the vehicle roof.
[0037] The top cover outer plate 1 and the top cover inner plate 2 are carbon fiber plates, and the reinforcing tube 3 is a carbon fiber reinforcing tube 3. The top cover outer plate 1, the top cover inner plate 2 and the reinforcing tube 3 are made of carbon fiber materials, which is conducive to reducing the weight of the vehicle top cover structure and realizing the lightweight of the vehicle. The carbon fiber composite material also has good impact resistance and can better absorb energy when it is hit, thereby improving the safety performance of the vehicle.
[0038] In some embodiments, the first reinforcing rib assembly 4 includes a plurality of first reinforcing ribs 41, and the plurality of first reinforcing ribs 41 are cross-arranged to form a mesh reinforcing rib structure. The plurality of first reinforcing ribs 41 are cross-arranged to increase the contact area between the first reinforcing rib assembly 4 and the top cover outer panel 1 and the top cover inner panel 2. When the top of the vehicle is subjected to top pressure, the force received can be dispersed to the surroundings, so that the force on the top area of the vehicle corresponding to the first reinforcing rib assembly 4 is evenly distributed, thereby improving the compression resistance and deformation resistance of the vehicle top cover structure.
[0039] For example, the plurality of first reinforcing ribs 41 may be arranged in a horizontal and vertical cross arrangement, an oblique cross arrangement, or a combination of the first reinforcing ribs 41 arranged in a horizontal and vertical cross arrangement and the first reinforcing ribs 41 arranged in an oblique cross arrangement. The horizontal and vertical cross arrangement refers to the cross arrangement of the plurality of first reinforcing ribs 41 to form a plurality of rectangular structures; the oblique cross arrangement refers to the arrangement of two adjacent first reinforcing ribs 41 in an X shape.
[0040] The first reinforcing rib assembly 4 further includes two first connecting ribs 42 arranged at intervals, and a plurality of first reinforcing ribs 41 are cross-arranged between the two first connecting ribs 42 and are respectively connected to the first connecting ribs 42. The two first connecting ribs 42 are used to connect to the first reinforcing ribs 41, limit the arrangement range of the plurality of first reinforcing ribs 41, support the top cover inner panel 2 and the top cover outer panel 1, and improve the structural strength of the vehicle top cover structure.
[0041] Exemplarily, the first reinforcing rib assembly 4 is protruding toward the top cover outer panel 1, and the height of the first reinforcing rib assembly 4 is 25mm-35mm. The draft angle of the first reinforcing rib 41 is 3°.
[0042] Furthermore, a door hinge mounting structure 6 is provided between the top cover outer panel 1 and the top cover inner panel 2. The door hinge mounting structure 6 can be provided on the top cover outer panel 1 or on the top cover inner panel 2. The first reinforcing rib assembly 4 is connected to the door hinge mounting structure 6, which can improve the installation stiffness of the door hinge mounting structure 6.
[0043] The second reinforcing rib assembly 5 includes a plurality of second reinforcing ribs 51, which are arranged at intervals in sequence along the length direction or the width direction of the top cover. The plurality of second reinforcing ribs 51 arranged at intervals increase the contact area between the second reinforcing rib assembly 5 and the top cover outer panel 1 and the top cover inner panel 2, and improve the structural strength of the vehicle top cover structure. When the plurality of second reinforcing ribs 51 are arranged at intervals in sequence along the length direction of the top cover, the force transmission channel on the top of the vehicle is: vehicle A-pillar 100-reinforcing tube 3-first connecting rib 42-multiple second reinforcing ribs 51, forming a plurality of continuous force transmission channels, which improves the force transmission effect during collision when the front or rear of the vehicle is hit.
[0044] The second reinforcing rib assembly 5 also includes two second connecting ribs 52 arranged at intervals, and a plurality of second reinforcing ribs 51 are arranged between the two second connecting ribs 52 and are respectively connected to the second connecting ribs 52. The second connecting rib 52 and the two adjacent second reinforcing ribs 51 can form an annular reinforcing rib structure. An integral annular reinforcing rib structure is formed, and its strength is higher than that of a non-integral reinforcing rib structure. The two second connecting ribs 52 are used to connect with the second reinforcing ribs 51, limit the arrangement range of the plurality of second reinforcing ribs 51, support the top cover inner panel 2 and the top cover outer panel 1, and improve the structural strength of the vehicle top cover structure.
[0045] Exemplarily, the second reinforcing rib assembly 5 is protruding toward the top cover outer panel 1, and the height of the second reinforcing rib assembly 5 is 25 mm-35 mm. The draft angle of the second reinforcing rib 51 is 3°.
[0046] Furthermore, the first reinforcing rib assembly 4 is arranged in the middle of the roof, and the front and rear sides of the middle area of the roof have reinforcing structures, and the position has a lower demand for structural strength reinforcement; the second reinforcing rib assembly 5 is arranged in the rear of the roof, and the vehicle is easily hit by a rear collision, and the rear area of the vehicle roof is connected to the vehicle C-pillar, the vehicle D-pillar, etc., and the vehicle roof needs to strengthen the structural strength of the vehicle C-pillar, the vehicle D-pillar, etc., so the rear area of the vehicle roof has a higher demand for structural strength reinforcement. Therefore, the arrangement area of the first reinforcing rib assembly 4 can be smaller than the arrangement area of the second reinforcing rib assembly 5, so the distance between the two first connecting ribs 42 of the first reinforcing rib assembly 4 is smaller than the distance between the two second connecting ribs 52 of the second reinforcing rib assembly 5.
[0047] The first reinforcing rib assembly 4 and the second reinforcing rib assembly 5 are an integrated structure. The reinforcing tube 3 and the first reinforcing rib assembly 4 are connected, so that the reinforcing tube 3, the first reinforcing rib assembly 4 and the second reinforcing rib assembly 5 form a continuous force transmission channel to improve the force transmission effect.
[0048] like Figure 3As shown, the top cover outer panel 1 and the reinforcing tube 3, the top cover inner panel 2 and the reinforcing tube 3, the top cover outer panel 1 and the reinforcing rib assembly, and the reinforcing tube 3 and the first reinforcing rib assembly 4 are respectively connected by structural adhesive 7. The structural adhesive 7 can withstand a large load and is resistant to aging, fatigue and corrosion. The various structures are connected by the structural adhesive 7, and the installation stability is high.
[0049] In this embodiment, the reinforcing rib assembly is pre-installed on the top cover inner plate 2 to facilitate the assembly of the top cover outer plate 1 and the top cover inner plate 2. The reinforcing rib assembly can be integrally formed with the top cover inner plate 2, or fixedly connected to the top cover inner plate 2 by the above-mentioned structural adhesive 7 or the like.
[0050] The two ends of the top cover outer panel 1 are respectively moved toward the top cover inner panel 2 and connected to the top cover inner panel 2 at both ends, and the top cover outer panel 1 and the top cover inner panel 2 are connected by structural adhesive 7 to improve the installation structural strength between the top cover outer panel 1 and the top cover inner panel 2.
[0051] The reinforcement rib assembly is a fabric ply structure, in which the fabric is laid layer by layer in a predetermined direction and sequence in a mold until the required thickness (for example, 25 mm), and then cured, demolded, and trimmed by heating and pressurizing. This type of structure has high strength and toughness, which is beneficial to improving the overall structural strength and deformation resistance of the vehicle roof structure.
