[0037] Reference Figure 1-Figure 3 As shown, according to an embodiment of the present application, a reinforcement member 1 is provided. The reinforcement member 1 includes a base plate 11, a folding plate 12 and a connecting body 13, wherein the folding plate 12 includes a first sub-plate 121 and a second sub-plate 122 connected to each other, wherein the first sub-plate 121 is connected to the base plate 11, and the second sub-plate 122 is arranged opposite to the base plate 11, and the folding plate 12 and at least a part of the base plate 11 jointly define a limit frame for cooperating with a cross beam of a vehicle frame; the connecting body 13 is connected to the folding plate 12, and the connecting body 13 is arranged obliquely relative to the base plate 11; the connecting body 13 is provided with a receiving cavity 130, and the receiving cavity 130 is configured to receive at least a part of the structure of the curved beam of the vehicle frame.

[0038] The reinforcement member 1 provided in the embodiment of the present application is used to connect the curved beam 2 of the frame and the middle cross beam 3 of the frame. Among them, the base plate 11 is connected to the sub-frame 4. The folding plate 12 and the base plate 11 are jointly connected to the middle cross beam 3 of the frame; specifically, the folding plate 12 and the partial structure of the base plate 11 are enclosed to form a limit frame, and at least part of the structure of the cross beam 3 is located in the limit frame. The connector 13 is connected to the curved beam 2 of the frame, and specifically, at least part of the structure of the curved beam 2 is arranged in the accommodating cavity 130 opened by the connector 13. In addition, the connector 13 is inclined relative to the base plate 11, so that it can better adapt to the curved structure of the curved beam 2.

[0039] The use of the reinforcement 1 to connect the curved beam 2 and the cross beam 3 can not only better fix the curved beam 2 and the cross beam 3, but also, compared with directly connecting the curved beam 2 and the cross beam 3, the use of the reinforcement 1 can make the forces on the curved beam 2 and the cross beam 3 more dispersed, avoiding stress concentration, thereby avoiding fracture at the connection between the curved beam 2 and the cross beam 3.

[0040] Reference Figure 1-Figure 2As shown, in one embodiment, the base plate 11 and the folding plate 12 together define a limit frame for cooperating with the crossbeam of the frame on one side of the first sub-plate 121;

[0041] On the other side of the first sub-plate 121 , the base plate 11 is provided with a positioning hole 110 , and the base plate 11 is connected to the sub-frame at the positioning hole 110 via a fastener.

[0042] In this specific example, the base plate 11 is connected to the cross beam 3 on one side of the first sub-plate 121, and is connected to the sub-frame 4 on the other side of the first sub-plate 121, so that the force of the entire frame is relatively dispersed and stress concentration is avoided.

[0043] Reference Figure 1-Figure 2 As shown, in one embodiment, the substrate 11 has a first surface 111 arranged opposite to the second sub-plate 122, the second sub-plate 122 has a second surface 1220 arranged opposite to the substrate 11, the first sub-plate 121 has a third surface 1210 arranged close to the first surface 111 and the second surface 1220, and the first surface 111, the second surface 1220 and the third surface 1210 are all fitted and connected to the crossbeam of the frame.

[0044] In this specific example, the first surface 111 of the substrate 11, the second surface 1220 of the second sub-plate 122 and the third surface 1210 of the first sub-plate 121 respectively form a three-sided clamping effect on the beam 3 from the three sides of the beam 3; and the first surface 111, the second surface 1220 and the third surface 1210 are all welded to the beam 3, thereby well ensuring the reliability of the connection and fixation between the reinforcement 1 and the beam 3.

[0045] Reference Figure 1-Figure 2 As shown, in one embodiment, the connecting body 13 has a first side wall 131, a second side wall 132, a third side wall 133 and a fourth side wall 134, the first side wall 131 is arranged opposite to the second side wall 132, and the third side wall 133 is arranged opposite to the fourth side wall 134;

[0046] The first side wall 131 , the second side wall 132 , the third side wall 133 and the fourth side wall 134 together enclose the accommodating cavity 130 ; the first side wall 131 , the second side wall 132 , the third side wall 133 and the fourth side wall 134 are all fitted and connected to the curved beam of the frame.

[0047] In this specific example, the first side wall 131 , the second side wall 132 , the third side wall 133 and the fourth side wall 134 of the connecting body 13 are all connected to the curved beam 2 , so that the reliability of the connection and fixation between the connecting body 13 and the curved beam 2 can be ensured.

[0048] Reference Figure 1-Figure 2 As shown, in one embodiment, the first side wall 131 and / or the second side wall 132 is provided with a notch portion 1300, and the notch portion 1300 is communicated with the accommodating cavity 130;

[0049] The notch portion 1300 is configured to weld the connecting body 13 and the curved beam of the vehicle frame through the notch portion 1300 .

[0050] In this specific example, the connector 13 and the curved beam 2 of the frame can be welded via the notch 1300 provided in the first side wall 131 and / or the second side wall 132, so as to better fix the connector 13 and the curved beam 2, and make the connector 13 and the curved beam 2 more firmly connected. The notch 1300 can make welding operations more convenient.

[0051] Reference Figure 1-Figure 2 As shown, in one embodiment, when the first side wall 131 and the second side wall 132 are both provided with the notch portion 1300 , the two notch portions 1300 are arranged opposite to each other.

[0052] In this specific example, the first side wall 131 and the second side wall 132 are both provided with a notch 1300, so that the connector 13 and the curved beam 2 can be welded from both sides of the connector 13, thereby making the connection between the connector 13 and the curved beam 2 more secure. In addition, the two notches 1300 are arranged opposite to each other, so that the two positions where the connector 13 and the curved beam 2 are welded are symmetrical to each other, which is more conducive to improving the reliability of the connection between the connector 13 and the curved beam 2.

[0053] Reference Figure 1-Figure 2 As shown, in one embodiment, the reinforcement 1 also includes two first reinforcement ribs 14, one of which is connected to the middle position of the side of the third side wall 133 away from the fourth side wall 134, and the other is connected to the middle position of the side of the fourth side wall 134 away from the third side wall 133.

[0054] In this specific example, the two first reinforcing ribs 14 are respectively arranged in the middle of the outer side surface of the third side wall 133 and the middle of the outer side surface of the fourth side wall 134. When the connector 13 is connected to the curved beam 2, the two first reinforcing ribs 14 respectively play a reinforcing and supporting role in the middle of the side wall of the curved beam 2; thereby, the reinforcement 1 can not only effectively ensure the fixed state and strength of the curved beam 2 of the frame and the middle cross beam 3 of the frame, but also effectively ensure the strength of the entire chassis frame during load operation, and can effectively solve the stress problem generated by the curved beam 2 of the frame and the middle cross beam 3 of the frame after separate welding.

[0055] Reference Figure 1-Figure 2 As shown, in one embodiment, the reinforcement also includes two second reinforcement ribs 15, one of which is connected to the side end position of the third side wall 133 away from the fourth side wall 134, and the other is connected to the side end position of the fourth side wall 134 away from the third side wall 133.

[0056] In this specific example, the two second reinforcing ribs 15 are respectively arranged at the outer side end portions of the third side wall 133 and the outer side end portions of the fourth side wall 134. After the connector 13 is connected to the curved beam 2, the two second reinforcing ribs 15 respectively play a reinforcing and supporting role at the side wall ends of the curved beam 2, thereby further ensuring the fixed state and strength of the curved beam 2 of the frame and the middle cross beam 3 of the frame.

[0057] Reference Figure 3 As shown, according to another embodiment of the present application, a vehicle frame is provided, the vehicle frame comprising the reinforcement 1 as described above, and also comprising a bent beam 2 and a cross beam 3, the bent beam 2 being connected to the connector 13, and at least a portion of the structure of the bent beam 2 being arranged in the accommodating cavity 130; the cross beam 3 being connected to the folding plate 12 and the base plate 11, and at least a portion of the structure of the cross beam 3 being arranged in the limiting frame; in addition, the vehicle frame also comprises a sub-frame 4, and the sub-frame 4 is connected to the base plate 11 at the positioning hole 110 by fasteners such as bolts.

[0058] The vehicle frame provided in the embodiment of the present application uses the above-mentioned reinforcement member 1 to connect the curved beam 2 and the cross beam 3, so that stress concentration will not occur at the connection between the curved beam 2 and the cross beam 3, thereby avoiding fracture at the connection between the curved beam 2 and the cross beam 3, improving the safety of the frame, and being able to suppress the distortion of the chassis.
