[0001] The utility model relates to the technical field of vehicle components, in particular to a leaf spring support and a vehicle with the same. Background Art

[0002] Due to the large load, domestic heavy trucks have higher and higher design requirements for chassis structural parts, which are required to be not only strong, but also light and low cost. Leaf spring supports, as one of the important structural parts of the chassis, play an important supporting role for heavy trucks. However, leaf spring support structures in related technologies mostly adopt semi-closed surface structures, which have many surfaces, thick walls, bulky weight, and high cost, and cannot meet the trend of lightweighting. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a leaf spring support, which has the advantages of high lightness and easy assembly while ensuring structural strength.

[0004] The utility model also provides a vehicle with a leaf spring support.

[0005] To achieve the above-mentioned purpose, according to an embodiment of the utility model, a leaf spring support is proposed, including: a connecting outer plate, the connecting outer plate is configured with a mounting hole, and the mounting hole is suitable for being installed on a vehicle frame; a horizontal connecting portion, the horizontal connecting portion is connected to the bottom of the connecting outer plate; a first leaf spring connecting arm and a second leaf spring connecting arm, the first leaf spring connecting arm and the second leaf spring connecting arm are respectively connected to the opposite sides of the horizontal connecting portion and extend downward; a reinforcing rib, the reinforcing rib is connected to the inner circumference of the connecting outer plate and to the first leaf spring connecting arm, the reinforcing rib protrudes from the surface of the connecting outer plate, and a triangular hollow hole is formed between the reinforcing rib and the horizontal connecting plate portion.

[0006] According to the leaf spring support of the embodiment of the utility model, a triangular hollow hole is formed between the reinforcing rib and the horizontal connecting part. The hollow hole structure can effectively reduce the material usage of the leaf spring support and reduce the total weight of the leaf spring support. The formation of the hollow hole structure improves the structural strength and bearing capacity of the leaf spring support while ensuring the structural strength of the reinforcing rib itself. Specifically, the weight of the leaf spring support of this embodiment is about 6.1kg, which is about 19.7% lighter than the weight of the leaf spring support in the prior art of 7.6kg, achieving a lightweight design, effectively reducing the amount of material used, and improving the lightweight degree of the leaf spring support 1.

[0007] At the same time, the reinforcing rib structure is arranged in a shape, and also presents a triangular structure at the connection to the outer plate. The triangular structure has good stability compared to structures of other shapes.

Since the mounting hole structure is arranged at intervals at the top of the connection to the outer plate, it does not penetrate the reinforcing rib structure and does not damage the overall structure of the reinforcing rib. The reinforcing rib structure extends downward along the horizontal connection portion until it is connected to the first leaf spring connecting arm. The continuously extended reinforcing ribs can improve the overall strength of the leaf spring support and reduce the risk of its deformation and damage. The load can also be effectively transferred to the first leaf spring connecting arm, thereby improving the overall structural stability of the leaf spring support.

[0008] In addition, since the hollow hole structure effectively reduces the weight of the leaf spring support and provides ample operating space, it is more convenient and quick to assemble the leaf spring support, thereby improving the efficiency and convenience of assembly.

[0009] Therefore, the leaf spring support according to the embodiment of the utility model has the advantages of high lightness and easy assembly while ensuring structural strength.

[0035] The leaf spring support 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 5 As shown, the leaf spring support 1 according to the embodiment of the utility model includes a connecting outer plate 100 , a horizontal connecting portion 200 , a first leaf spring connecting arm 300 and a second leaf spring connecting arm 400 .

[0037] The connecting outer plate 100 is configured with a mounting hole 130, and the mounting hole 130 is suitable for mounting on a vehicle frame. The horizontal connecting portion 200 is connected to the bottom of the connecting outer plate 100. The first leaf spring connecting arm 300 and the second leaf spring connecting arm 400 are respectively connected to opposite sides of the horizontal connecting portion 200 and extend downward. The reinforcing rib 500 is connected to the inner circumference of the connecting outer plate 100 and to the first leaf spring connecting arm 300. The reinforcing rib 500 protrudes from the surface of the connecting outer plate 100, and a triangular hollow hole 110 is formed between the reinforcing rib 500 and the horizontal connecting plate portion 200.

[0038] For example, there can be two leaf spring supports 1, which are spaced apart along the front-to-back direction of the frame and are respectively installed at the two ends of the leaf spring (not shown in the figure). The first leaf spring connecting arm 300 and the second leaf spring connecting arm 400 are respectively located on both sides of the leaf spring to fix the leaf spring. The top of the connecting outer plate 100 is configured with a plurality of mounting holes 110, and the plurality of mounting holes 110 are fastened to the web of the frame longitudinal beam by passing fasteners. The horizontal connecting portion 200 is provided with two bolt holes, and the two bolt holes are fastened to the bottom surface of the frame longitudinal beam by passing fasteners.

[0039] According to the leaf spring support 1 of the embodiment of the utility model, a triangular hollow hole 110 is formed between the reinforcing rib 500 and the horizontal connecting portion 100. The hollow hole 110 structure can effectively reduce the material usage of the leaf spring support 1 and reduce the total weight of the leaf spring support 1. The formation of the hollow hole 110 structure improves the structural strength and bearing capacity of the leaf spring support 1 on the premise of ensuring the structural strength of the reinforcing rib 500 itself. Specifically, the weight of the leaf spring support 1 of this embodiment is about 6.1kg, which is about 19.7% lighter than the weight of the leaf spring support in the prior art of 7.6kg, achieving a lightweight design, effectively reducing the amount of material used, and improving the lightweight degree of the support.

[0040] At the same time, the reinforcing rib 500 structure is arranged in a shape, and also presents a triangular structure at the connection to the outer plate 100. The triangular structure has good stability compared to structures of other shapes. The arrangement of the reinforcing rib 500 makes the overall structure of the leaf spring support 1 more stable, and can effectively resist external forces and moments, thereby improving the overall stability of the leaf spring support 1. Since the mounting holes 130 structure are arranged at intervals at the top of the connection to the outer plate 100, they do not penetrate the reinforcing rib 500 structure, and will not damage the overall structure of the reinforcing rib 500. Moreover, the reinforcing rib 500 structure extends downward along the horizontal connection portion 200 until it is connected to the first leaf spring connecting arm 300. The continuously extended reinforcing rib 500 can improve the overall strength of the leaf spring support 1 and reduce the risk of its deformation and damage. The load can also be effectively transferred to the first leaf spring connecting arm 300, thereby improving the overall structural stability of the leaf spring support 1.

[0041] In addition, since the hollow hole 110 structure effectively reduces the weight of the leaf spring support 1 and provides ample operating space, it is more convenient and quick to assemble the leaf spring support 1, thereby improving the efficiency and convenience of assembly.

[0042] Therefore, the leaf spring support 1 according to the embodiment of the utility model has the advantages of high lightness and convenient assembly while ensuring structural strength.

[0043] In some specific embodiments of the present invention, Figure 4As shown, the connecting outer plate 100 is located in the middle of the horizontal connecting part 200 in the width direction, and the first leaf spring connecting arm 300 and the second leaf spring connecting arm 400 are symmetrical relative to the connecting outer plate 100. The symmetrically constructed first leaf spring connecting arm 300 and the second leaf spring connecting arm 400 can effectively reduce the risk of deformation or breakage caused by uneven force on the leaf spring support 1, and improve the stability and deformation resistance of the leaf spring support 1. By locating the connecting outer plate 100 in the middle of the horizontal connecting part 200, the pressure from the frame or other loads can be resisted by increasing the structural strength of the leaf spring support 1.

[0044] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the thickness of the reinforcing rib 500 gradually increases from top to bottom, and the reinforcing rib 500 extends to the outer side of the first leaf spring connecting arm 300. Specifically, the thickness of the part of the reinforcing rib 500 connecting the outer plate 100 and the horizontal connecting part 200 gradually increases from top to bottom. By gradually increasing the thickness of the reinforcing rib 500, the force-bearing area of ​​the reinforcing rib 500 at the force-bearing part can be increased, the overall bearing capacity of the leaf spring support 1 can be improved, and the possibility of structural deformation can be reduced. The reinforcing rib 500 extends to the outer side of the first leaf spring connecting arm 300, which can effectively enhance the stability of the structure of the leaf spring support 1. The extended structure of the reinforcing rib 500 enables the various parts of the leaf spring support 1 to form effective support and connection when subjected to force, prevents displacement or distortion of the structure, and improves the overall stability of the structure.

[0045] In some specific embodiments of the present invention, Figure 2 As shown, the leaf spring support 1 is constructed with a continuously extending weight-reducing groove 11 on the inner side surface of the first leaf spring connecting arm 300, the bottom surface of the horizontal connecting part 200, and the inner side surface of the second leaf spring connecting arm 400. The weight-reducing groove 11 structure can effectively remove a portion of the material in the leaf spring support 1 structure, thereby reducing the overall weight of the leaf spring support 1 by reducing the amount of material used. While ensuring that the leaf spring support 1 has sufficient structural strength and stability, the weight of the leaf spring support 1 is reduced, which complies with the lightweight structure. At the same time, the weight-reducing groove 11 structure can increase the space gap inside the leaf spring support 1, making it easier for the leaf spring support 1 to avoid other components or structures, thereby improving the convenience and flexibility of the overall assembly.

[0046] In some specific embodiments of the present invention, Figure 4As shown, the portion of the horizontal connection part 200 adjacent to the second leaf spring connecting arm 400 exceeds the front and rear sides of the second leaf spring connecting arm 400. The horizontal connection part 200 exceeding the front and rear sides of the second leaf spring connecting arm 400 can provide a wider connection area, thereby increasing the connection stability between the leaf spring support 1 and other structural parts. This structure can ensure that the connection between the horizontal connection part 200 and the second leaf spring connecting arm 400 is more secure, reduce the possibility of deformation or displacement of the overall structure of the leaf spring support 1 when subjected to force, and improve the overall stability of the leaf spring support 1. At the same time, the horizontal connection part 200 can provide a larger support area, effectively increase the bearing capacity of the overall structure, and make the leaf spring support 1 safer and more reliable when subjected to external loads.

[0047] In some specific embodiments of the present invention, Figure 5 As shown, the portion of the horizontal connection part 200 adjacent to the second leaf spring connecting arm 400 is configured as a trapezoid, and the portion of the horizontal connection part 200 adjacent to the first leaf spring connecting arm is configured as a rectangle. The combination of the trapezoidal and rectangular structures can optimize the force distribution and stress transfer. The trapezoidal portion can adjust the stiffness and deformation characteristics of the support according to the different positions of the support points to adapt to different load conditions, so that the leaf spring support 1 can distribute the load more reasonably when subjected to force. The rectangular portion transfers the load more stably, reduces the possibility of stress concentration, and increases the service life of the support.

[0048] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the mounting holes 130 include a front mounting hole 131, a front upper mounting hole 132, a rear mounting hole 133 and a rear upper mounting hole 134. The front mounting hole 131, the front upper mounting hole 132, the rear mounting hole 133 and the rear upper mounting hole 134 are arranged in a trapezoid. Arranging the plurality of mounting holes 130 in a trapezoidal shape can optimize force transfer, so that when the leaf spring support 1 is subjected to an external load, the force is more evenly transferred to the supporting structure, reducing stress concentration and reducing the risk of damage caused by unbalanced structural force. At the same time, the arrangement of the mounting holes 130 in a trapezoidal shape helps to increase the stability of the installation. Compared with a single arrangement, the trapezoidal arrangement can provide more installation options, so that the leaf spring support 1 can be more firmly fixed to the frame during installation, reducing the loosening or displacement that may occur during the installation process, and improving the overall stability of the leaf spring support 1.

[0049] In some specific embodiments of the present invention, Figure 1 and Figure 2As shown, the shape of the connecting outer panel 100 is symmetrical along the front-to-back direction, and the front mounting hole 131, the front upper mounting hole 132, the rear mounting hole 133 and the rear upper mounting hole 134 are arranged in an isosceles trapezoid. Symmetrical structures such as the connecting outer panel 100 and the mounting holes 110 help to improve the stability of the leaf spring support 1. The symmetrical structure in the front-to-back direction can make the force distribution of the leaf spring support 1 more uniform when it is subjected to force, reduce the impact of asymmetric loads on the structure, improve the overall force balance, and increase the stability and safety of the support. At the same time, through the symmetrical design, the leaf spring support 1 is subjected to more uniform force when subjected to external loads, reduces stress concentration, and reduces the risk of structural damage and fatigue. The symmetrical structure can also improve the overall stiffness of the structure and increase the bearing capacity.

[0050] In some specific embodiments of the present invention, Figure 4 As shown, the connection between the first leaf spring connecting arm 300 and the horizontal connecting part 200, and the connection between the second leaf spring connecting arm 400 and the horizontal connecting part 200 are both constructed with chamfered arc surfaces. The structure of the chamfered arc surface can reduce stress concentration at the connection. Since the chamfered arc surface can provide a smooth transition, it reduces the sudden change and sharp edges at the connection, helps to disperse the force, reduce the stress concentration phenomenon, and thus reduce the fatigue and damage risk caused by the stress concentration of the structure.
