Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to a front crossbeam for an automotive roof. Background Technology

[0002] The roof crossbeam is a key load-bearing component in automotive mechanical engineering. It enhances the structural strength of the roof by providing lateral support. The roof crossbeam includes a front crossbeam and a rear crossbeam. The front crossbeam is located above the windshield of the vehicle body and is used to support the roof, install the roof light, and fix the windshield. The front crossbeam of the roof is used to enhance the rigidity and torsional rigidity of the vehicle body.

[0003] Existing roof front beams are generally designed with an arc shape and a "U"-shaped cross-section. The two ends of the opening at the top of the "U"-shaped cross-section have outward flanges. Although this design improves the structural strength of the front beam along its length, the structural strength and deformation resistance of the roof front beam in the width direction are still relatively weak. Therefore, this utility model proposes a mounting bracket for a permanent magnet synchronous motor. Summary of the Invention

[0004] The purpose of this utility model is to provide a front crossbeam for an automobile roof in order to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A front crossbeam for a car roof, comprising:

[0007] The beam body includes a top arc plate, a middle arc plate and a bottom arc plate connected in sequence. The longitudinal section of the middle arc plate is wavy. Two diagonal bracing plates are fixed between the top arc plate and the bottom arc plate.

[0008] Furthermore, a number of reinforcing plates are arranged in an array between the inclined brace plate and the bottom arc plate.

[0009] Furthermore, the reinforcing plate is constructed as a triangular plate and abuts against the central arc plate.

[0010] Furthermore, a weight-reducing groove is provided through the reinforcing plate.

[0011] Furthermore, the inner wall of the top arc plate has a plurality of first reinforcing ribs, which are located in the arch cavity of the middle arc plate.

[0012] Furthermore, the outer wall of the bottom arc plate has a number of second reinforcing ribs, which are located in the arch cavity of the middle arc plate.

[0013] Furthermore, the inner wall of the bottom arc plate has a plurality of third reinforcing ribs, which are perpendicular to the second reinforcing ribs.

[0014] Furthermore, support plates are fixed at both ends of the beam.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, the top arc plate, the middle arc plate and the bottom arc plate are connected in sequence. The longitudinal section of the middle arc plate is wavy. Two diagonal bracing plates are connected between the top arc plate and the bottom arc plate to form a beam, which not only improves the structural strength of the beam in the length direction, but also improves its structural strength in the width direction.

[0017] 2. In this utility model, by setting a reinforcing plate between the top arc plate, the middle arc plate, the bottom arc plate and the diagonal brace plate, not only is the connection strength between the four improved, but the structural strength in the width direction of the beam is also further improved.

[0018] 3. In this utility model, a first reinforcing rib and a second reinforcing rib are respectively constructed on the top arc plate and the bottom arc plate, which not only improves the strength of the two themselves, but also further improves the structural strength of the beam in the length direction.

[0024] The present invention will now be further described with reference to the accompanying drawings.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] Please see Figures 1-4 This utility model discloses a front crossbeam for a car roof, comprising: a beam body 1, including a top arc plate 101, a middle arc plate 102, and a bottom arc plate 103 connected in sequence. Preferably, the top arc plate 101, the middle arc plate 102, and the bottom arc plate 103 all have a certain curvature, and the three are welded together to form an arched structure, which can improve the structural strength of the beam body 1 in the length direction. The longitudinal section of the middle arc plate 102 is wavy. By making the longitudinal section of the middle arc plate 102 wavy, it not only strengthens the structural strength of the beam body 1 in the length direction, but also creates an arched cavity between the middle arc plate 102 and the top arc plate 101 or the bottom arc plate 103, so that the beam body 1 has several arched structures in the width direction, thereby improving the structural strength of the beam body 1 in the width direction. Two diagonal bracing plates 104 are fixed between the top arc plate 101 and the bottom arc plate 103. Figure 4 As shown, the width of the bottom arc plate 103 is greater than the width of the top arc plate 101. Two diagonal bracing plates 104 are connected between the top arc plate 101 and the bottom arc plate 103, so that the longitudinal section of the beam 1 forms a structure similar to an isosceles trapezoid, which can further improve the structural strength of the beam 1 in the width direction.

[0027] In this scheme, the top arc plate 101, the middle arc plate 102 and the bottom arc plate 103 are connected in sequence. The longitudinal section of the middle arc plate 102 is wavy. Two diagonal bracing plates 104 are connected between the top arc plate 101 and the bottom arc plate 103 to form a beam 1, which not only improves the structural strength of the beam 1 in the length direction, but also improves its structural strength in the width direction.

[0028] like Figure 3 and Figure 4 As shown, a further technical solution for the beam 1 of this utility model is disclosed. Several reinforcing plates 2 are arranged in an array between the diagonal bracing plate 104 and the bottom arc plate 103. By connecting the reinforcing plates 2 between the diagonal bracing plate 104 and the bottom arc plate 103, the support and reinforcement performance of the diagonal bracing plate 104 is further improved, thereby further improving the structural strength of the beam 1 in the width direction.

[0029] like Figure 3 and Figure 4 As shown, the present invention discloses a further technical solution for the reinforcing plate 2. The reinforcing plate 2 is constructed as a triangular plate and abuts against the middle arc plate 102. The reinforcing plate 2 is constructed as a triangular plate, which utilizes the more stable characteristics of triangles to further strengthen the connection between the top arc plate 101, the bottom arc plate 103 and the diagonal bracing plate 104. At the same time, since the middle arc plate 102 itself supports and connects the top arc plate 101 and the bottom arc plate 103, the reinforcing plate 2 abuts against the middle arc plate 102 (it can be welded and fixed in actual use), thereby further strengthening the structural strength of the beam 1 in the overall width direction.

[0030] like Figure 3 and Figure 4 As shown, the present invention discloses a further technical solution for the reinforcing plate 2. A weight-reducing groove 3 is provided through the reinforcing plate 2. Preferably, the weight-reducing groove 3 is also triangular, and its inner corner is transitioned by a rounded arc. By providing a weight-reducing groove 3 on the reinforcing plate 2, the overall weight of the beam 1 can be reduced without affecting the reinforcement, thereby improving practicality.

[0031] like Figure 4 As shown, a further technical solution for the top arc plate 101 of this utility model is disclosed. The inner wall of the top arc plate 101 is constructed with a plurality of first reinforcing ribs 4. The plurality of first reinforcing ribs 4 are respectively located in the arch cavity of the middle arc plate 102. By constructing the first reinforcing ribs 4 on the inner wall of the top arc plate 101 and the first reinforcing ribs 4 are located in the arch cavity, the strength of the top arc plate 101 can be improved without affecting the connection between the top arc plate 101 and the middle arc plate 102, thereby further improving the structural strength of the beam 1 in the length direction.

[0032] like Figure 4 As shown, the present invention discloses a further technical solution for the bottom arc plate 103. The outer wall of the bottom arc plate 103 has a plurality of second reinforcing ribs 5, which are respectively located in the arch cavity of the middle arc plate 102. By constructing the second reinforcing ribs 5 on the outer wall of the bottom arc plate 103 and having the second reinforcing ribs 5 located in the arch cavity, the strength of the bottom arc plate 103 can be improved without affecting the connection between the bottom arc plate 103 and the middle arc plate 102, thereby further improving the structural strength of the beam 1 in the length direction.

[0033] like Figure 3 As shown, a further technical solution for the bottom arc plate 103 of this utility model is disclosed. The inner wall of the bottom arc plate 103 has a plurality of third reinforcing ribs 6, which are perpendicular to the second reinforcing ribs 5. By constructing the third reinforcing ribs 6 on the inner wall of the bottom arc plate 103, and the third reinforcing ribs 6 being perpendicular to the second reinforcing ribs 5, the strength of the bottom arc plate 103 can be further improved, thereby improving the structural strength of the beam 1 in the width direction.

[0034] like Figure 1 and Figure 2 As shown, a further technical solution for the beam 1 of this utility model is disclosed. Both ends of the beam 1 are fixed with support plates 7. By fixing support plates 7 at both ends of the beam 1, the connection strength between the top arc plate 101, the middle arc plate 102, the bottom arc plate 103 and the diagonal brace plate 104 can be further improved. At the same time, it is also convenient for the beam 1 to be connected to other structures of the vehicle body (AB pillars or upper beams, etc.), thereby improving its practicality.

[0035] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
