[0028] Reference below Figure 1-Figure 6 The suspension bracket 100 according to the first embodiment of the utility model is described.

[0029] like Figure 1-Figure 6As shown, a suspension bracket 100 according to an embodiment of the first aspect of the utility model includes a bracket body 1 and a reinforcement plate 2.

[0030] Specifically, the bracket body 1 includes two first bracket segments 11 and a second bracket segment 12, the second bracket segment 12 is connected between the two first bracket segments 11, each first bracket segment 11 extends along the thickness direction of the second bracket segment 12, each first bracket segment 11 has a first bending portion 111, the first bending portion 111 extends in a direction away from the second bracket segment 12, and one end of the second bracket segment 12 in the length direction has an extension portion 121, and the extension portion 121 is suitable for overlapping with the frame 3. The reinforcing plate 2 is arranged on a side of the first bending portion 111 away from the second bracket segment 12, one end of the reinforcing plate 2 is connected to the first bending portion 111, and the other end of the reinforcing plate 2 is suitable for connecting with the frame 3.

[0031] For example, in Figure 1-Figure 6 In the example, the two first bracket segments 11 are arranged along the length direction of the frame 3 (for example, Figure 1 The two first bracket segments 11 are arranged in a spaced relationship and are arranged opposite to each other. The second bracket segment 12 is connected to the two first bracket segments 11 in the length direction (for example, Figure 1 The two first bracket segments 11 and the second bracket segment 12 form a U-shaped structure, and the bracket body 1 overlaps the frame 3. The first bending portion 111 of each first bracket segment 11 is located on a side of the first bracket segment 11 away from the second bracket segment 12, and the first bending portion 111 extends along the length direction of the frame 3, and the extension directions of the two first bending portions 111 are opposite.

[0032] The extension portion 121 is formed in the length direction of the second bracket segment 12 (for example, Figure 1 The extension portion 121 extends along the length direction of the second bracket section 12 toward the direction adjacent to the frame 3 until the extension portion 121 is connected to the frame 3. The bracket body 1 is an integrally formed structure, and the bracket body 1 is connected to the frame 3 by welding. The reinforcing plate 2 is provided in the thickness direction of the frame 3 (for example, Figure 1 On the side away from the extending portion 121 (in the front-to-back direction), the reinforcing plate 2 extends along the length direction of the frame 3, and the reinforcing plate 2 is connected to the frame 3 and the bracket body 1 at the same time.

[0033] Therefore, by forming a box-shaped structure with the bracket body 1 and the reinforcing plate 2, the structural strength and dynamic stiffness of the bracket body 1 are enhanced, so that the connection between the bracket body 1 and the suspension has stronger reliability. At the same time, the provision of the reinforcing plate 2 improves the connection strength between the bracket body 1 and the frame 3, reduces the resonance effect of the bracket body 1 and the frame 3, prevents the connection between the bracket body 1 and the frame 3 from breaking, improves the structural stability of the bracket body 1 and the frame 3, and also improves the driving stability of the vehicle, thereby enhancing the riding experience of the passengers.

[0034] According to a suspension bracket 100 of an embodiment of the utility model, the bracket body 1 and the reinforcing plate 2 form a box-shaped structure, and a first bending portion 111 is provided on the bracket body 1, and the reinforcing plate 2 is respectively connected to the bracket body 1 and the frame 3. Therefore, compared with the traditional suspension bracket, the structural strength and dynamic stiffness of the bracket body 1 are enhanced, the connection strength between the bracket body 1 and the frame 3 is improved, the resonance between the bracket body 1 and the frame 3 is reduced to affect the whole vehicle, the connection between the bracket body 1 and the frame 3 is prevented from being broken, the structural stability of the bracket body 1 and the frame 3 is improved, the driving stability of the vehicle is improved, and the riding experience of the passengers is improved.

[0035] According to some embodiments of the present invention, the cross-sectional area of ​​the first bent portion 111 gradually increases in the direction toward the extension portion 121, and the reinforcing plate 2 is connected to an end of the first bent portion 111 adjacent to the extension portion 121. Figure 1-Figure 6 , in the width direction of the first bracket segment 11 (for example, Figure 1 In the up-down direction (in the vertical direction), the cross-sectional area of ​​the first bent portion 111 gradually increases from the end away from the frame 3 to the end close to the frame 3.

[0036] Because the reinforcing plate 2 is connected to one end of the first bending portion 111 adjacent to the vehicle frame 3, when the reinforcing plate 2 is connected to the first bending portion 111, the contact area between the reinforcing plate 2 and the first bending portion 111 is increased, thereby improving the connection strength between the reinforcing plate 2 and the first bending portion 111, and reducing the pressure on the first bending portion 111, thereby preventing the first bending portion 111 from cracking due to excessive force, thereby enhancing the rigidity of the first bracket segment 11, making the connection strength of the first bracket segment 11 when connected to the suspension more reliable, and improving the structural strength of the bracket body 1.

[0037] According to some embodiments of the present invention, the reinforcing plate 2 has a plurality of lugs 221. In the description of the present invention, "plurality" means two or more. The plurality of lugs 221 are respectively located at both ends of the reinforcing plate 2 in the length direction. The lugs 221 are located on the side of the first bending portion 111 away from the first bracket segment 11. Figure 2 and Figure 6As shown, the number of the lugs 221 may be two, and the two lugs 221 are respectively located in the length direction of the reinforcing plate 2 (for example, Figure 1 The lug 221 is connected to the first bent portion 111, and the lug 221 is in contact with the first bent portion 111. Thus, the reinforcing plate 2 is connected to the bracket body 1, and the reinforcing plate 2 can strengthen the connection between the bracket body 1 and the frame 3, enhance the structural rigidity of the bracket body 1, reduce the resonance effect of the bracket body 1 during vehicle driving, reduce the risk of cracking of the bracket body 1 under a large load, and increase the service life of the bracket body 1.

[0038] Further, the reinforcing plate 2 includes a first connecting section 21 and a second connecting section 22. Specifically, the first connecting section 21 is suitable for connecting to the vehicle frame 3. The second connecting section 22 is connected to the first connecting section 21, and a lug portion 221 is provided on a side of the second connecting section 22 away from the first connecting section 21. The angle between the first connecting section 21 and the second connecting section 22 is an obtuse angle.

[0039] For example, in Figure 2 and Figure 6 In the example, the first connecting section 21 and the second connecting section 22 are arranged along the height direction of the first bracket section 11, and the first connecting section 21 and the second connecting section 22 are extended along the length direction of the frame 3. The two lugs 221 are respectively located at both ends of the second connecting section 22 in the length direction, and the lugs 221 extend from a side of the second connecting section 22 away from the first connecting section 21 toward a direction away from the second connecting section 22, so that the lugs 221 are connected to the first bending portion 111.

[0040] By setting the included angle between the first connecting section 21 and the second connecting section 22 to be an obtuse angle, the structural strength of the reinforcing plate 2 is enhanced, the connection between the lug portion 221 and the first bending portion 111 is facilitated, and the reinforcing plate 2 can be connected to the frame 3 and the bracket body 1 at the same time, which is beneficial to improve the rigidity of the bracket body 1, and further beneficial to ensure the stability and firmness of the suspension connection.

[0041] Furthermore, the lug 221 is welded to the first bent portion 111. Specifically, after the lug 221 is attached to the first bent portion 111, welding is performed along the edge of the lug 221, so that the lug 221 can be fixedly connected to the first bent portion 111, and after the welding liquid solidifies at the edge of the lug 211, a welding rod 2211 is formed at the edge of the lug 211, and the welding rod 2211 extends along the circumference of the lug 221, and the welding rod 2211 is connected to the first bent portion 111. Figure 1 and Figure 6The edge of the lug 221 is roughly arc-shaped. By welding along the edge of the lug 211, the length of the welding rod 2211 is increased, and the reliability of welding can be improved. The lug 221 and the first bent portion 111 are fixedly connected by welding 1, which can enhance the connection strength between the first bent portion 111 and the lug 221, so that the reinforcing plate 2 can improve the connection strength between the bracket body 1 and the frame 3.

[0042] According to some embodiments of the present invention, the other end of the second bracket segment 12 in the longitudinal direction is provided with a second bending portion 122, the second bending portion 122 extends in the direction toward the first bracket segment 11, and the end of the second bending portion 122 is spaced apart from the end of the first bending portion 111. Figure 3 and Figure 4 As shown, a second bending portion 122 is provided on the side of the second bracket section 12 in the length direction away from the vehicle frame 3. The second bending portion 122 is bent toward the first bracket section 11, so that when the bracket body 1 shakes, the sharper side of the second bending portion 122 faces the first bracket section 11, which can reduce the risk of the second bending portion 122 cutting the fuel tank. The two ends of the second bending portion 122 in the length direction are spaced from the first bending portion 111, which can avoid stress at the connection between the first bending portion 111 and the second bending portion 122, improve the structural strength, save the production materials of the bracket body 1, and reduce the weight of the bracket body 1.

[0043] According to some embodiments of the present invention, a third bending portion 112 is provided at one end of each first bracket segment 11 adjacent to the extension portion 121. The third bending portion 112 extends along the thickness direction of the first bracket segment 12 (for example, Figure 1 The third bending portion 112 extends in the left-right direction, one end of the third bending portion 112 is connected to the extending portion 121, and the other end of the third bending portion 112 is spaced apart from the first bending portion 111.

[0044] For example, in Figure 4 In the example, the third bending portion 112 is located at one end of the extension portion 121 adjacent to the height direction of the first bracket segment 11. The third bending portion 112 extends in a direction away from the first bracket segment 11, and the third bending portion 112 is connected to the frame 3. One end of the third bending portion 112 adjacent to the second bracket segment 12 is connected to the extension portion 121, and the extension portion 121 and the third bending portion 112 are welded, and the extension portion 121 and the third bending portion 112 are both welded to the frame 3, so that the connection strength between the bracket body 1 and the frame 3 is enhanced. A gap is formed between the other end of the third bending portion 112 and the first bending portion 111, which reduces the weight of the bracket body 1 and avoids stress at the connection between the third bending portion 112 and the first bending portion 111, which is beneficial to improve the rigidity of the bracket body 1.

[0045] Furthermore, each first bracket segment 11 is formed with an avoidance gap 113, and the avoidance gap 113 is located between the first bending portion 111 and the third bending portion 112. Figure 4 The edge of the avoidance notch 113 is roughly arc-shaped. The avoidance notch 113 can reduce the stress between the first bracket segment 11 and the third bending portion 112, and can also reduce the stress between the first bracket segment 11 and the first bending portion 111, thereby preventing the connection between the first bracket segment 11 and the third bending portion 112, the connection between the first bracket segment 11 and the first bending portion 111, or the first bracket segment 11 from breaking, thereby improving the structural strength of the bracket body 1 and ensuring the reliability of the connection between the suspension and the bracket body 1.

[0046] According to some embodiments of the present invention, a side surface of each first bracket segment 11 away from the second bracket segment 12 is inclined in a direction toward the extension portion 121. Figure 1-Figure 6 As shown, the side of each first bracket segment 11 away from the second bracket segment 12 is extended obliquely to ensure the clearance requirement between the bracket body 1 and the suspension, and the clearance between the bracket body 1 and the suspension can gradually increase from the end of the first bracket segment 11 away from the reinforcing plate 2 to the end of the first bracket segment 11 adjacent to the reinforcing plate 2. Therefore, when the vehicle shakes during driving, it can prevent the bracket body 1 from contacting the surface of the suspension to affect the reliability of the connection, and also avoid damage to the bracket body 1 and the suspension.

[0048] According to the vehicle of the embodiment of the utility model, by adopting the above-mentioned suspension bracket 100, the structural strength and dynamic stiffness of the suspension bracket 100 are enhanced, the reliability of the connection between the suspension bracket 100 and the suspension is improved, the resonance effect of the vehicle is reduced, and it is beneficial to the driving safety of the vehicle.
