[0027] In the embodiment, as Figure 1As shown, the support bottom plate body 310 is a rectangular plate structure, which is installed and fixed on the axle 100 in the vertical direction during installation. The support bottom plate body 310 has opposite end portions along its length direction. The horizontal push connecting plate body 320 and the side connecting plate body 330 are both plate structures. One end of the horizontal push connecting plate body 320 is fixedly connected to one end portion of the end face of the support bottom plate body 310 opposite to the axle 100. The extending direction of the horizontal push connecting plate body 320 is perpendicular to the plane in which the support bottom plate body 310 is located. An installation portion 321 is arranged on one end face of the horizontal push connecting plate body 320. During use, the installation portion 321 can be connected with one end of the horizontal push. The other end of the horizontal push connecting plate body 320 is fixedly connected with one end of the side connecting plate body 330. The other end of the side connecting plate body 330 is fixedly connected with the other end portion of the support bottom plate body 310. The side connecting plate body 330 is fixedly connected to the support bottom plate body 310 in an inclined manner, so that the cross section of the support bottom plate body 310, the horizontal push connecting plate body 320 and the side connecting plate body 330 after connection is in a triangular structure. After fixed connection, there is a gap between the support bottom plate body 310, the horizontal push connecting plate body 320 and the side connecting plate body 330. A support plate assembly is fixedly connected in the gap. The side ends of the support plate assembly are fixedly connected with the support bottom plate body 310, the horizontal push connecting plate body 320 and the side connecting plate body 330, respectively.

[0028] In the above structure, the support bottom plate body 310, the horizontal push connecting plate body 320 and the side connecting plate body 330 are connected to form a triangular structure, which improves the structural strength and stability of the support. The lateral load can be effectively dispersed and transmitted, and the bending and compression resistance is effectively enhanced. In addition, the support plate assembly is connected between the support bottom plate body 310, the side connecting plate body 330 and the horizontal push connecting plate body 320, which further improves the structural stability.

[0029] In the specific structure of the horizontal push connecting plate body 320, two fixed holes are arranged on one end face of the horizontal push connecting plate body 320 and spaced apart in the first direction. The fixed holes penetrate through the horizontal push connecting plate body 320. The fixed holes are connected with the horizontal push through a fixed pin body to form the installation portion 321. An arc-shaped avoiding slot 322 is arranged between the two fixed holes of the horizontal push connecting plate body 320, which can accommodate part of the horizontal push. The thickness of the horizontal push connecting plate body 320 is greater than the thickness of the support bottom plate body 310 and the side connecting plate body 330.

[0030] In this embodiment, one end surface of the transverse push connecting plate body 320 is provided with a fixing hole extending through its own thickness direction, which forms a mounting portion 321, wherein two fixing holes are arranged at intervals along the length direction of the transverse push connecting plate body 320, and the interval of the two fixing holes is determined by the length of the ball pin of the transverse push to be connected. During installation, the ball pin is connected with the fixing hole through a fixing pin body, wherein the fixing pin body can be a bolt. The fixing pin body is sequentially inserted through the ball pin and the fixing hole, and a nut is installed at the other end of the fixing hole to fix the bolt, thereby connecting the transverse push with the support. This connection structure is simple, and the connection through the fixing pin body inserted through the fixing hole can provide the basis for support and fixing force, which ensures that the support can flexibly adapt to the force transmission in the suspension system under dynamic load, while ensuring the stable connection of the transverse push, effectively providing transverse push force, and ensuring that the push rod can effectively transmit and disperse impact force and vibration.

[0031] In addition, an arc-shaped avoiding groove 322 is arranged on the end surface of the transverse push connecting plate body 320 close to the transverse push and between the two fixing holes, wherein the arc-shaped avoiding groove 322 is recessed away from the transverse push, and the structure of the arc-shaped avoiding groove 322 can be a “C” type structure or a “U” type structure. Therefore, when the transverse push is connected, part of the transverse push can be accommodated in the arc-shaped avoiding groove 322, so that the connection structure is more compact. In addition, the structure of the arc-shaped avoiding groove 322 can make the transverse push connecting plate body 320 provide a larger transverse support surface, enhance the bending stiffness of the support, and effectively disperse and transmit the transverse force from the vehicle body to avoid deformation of the suspension system due to stress concentration. The opening direction of the arc-shaped avoiding groove 322 is consistent with the action direction of the transverse push, which ensures the stability and reliability of the transverse push connection structure, and provides sufficient flexibility for the transverse push connection, so that the transverse push and the support can be properly adjusted in angle, and strong fixation is ensured to prevent loosening.

[0032] In particular, the thickness of the transverse push connecting plate body 320 is greater than the thickness of the support bottom plate body 310 and the thickness of the side connecting plate body 330, which further improves the structural strength and connection stability of the connection, and further improves the bending and compression resistance and increases the structural rigidity.

[0033] In the specific structure of the support plate assembly, as Figure 1 , Figure 2As shown, the support plate assembly includes a first support plate body 340 and a second support plate body 350, both of which are triangular structures, and both of which are fixedly connected to the transverse push connecting plate body 320 at one end, so that the first support plate body 340, the second support plate body 350, the transverse push connecting plate body 320, the side connecting plate body 330 and the support base plate body 310 form a closed frame structure. The first support plate body 340 is arranged close to the transverse push, and the first support plate body 340 is provided with a bent portion 341 bent in a direction away from the transverse push.

[0034] In this embodiment, the side connecting plate body 330, the transverse push connecting plate body 320 and the support base plate body 310 are connected and enclosed into a triangular structure, and the gap therebetween is also triangular. The support plate assembly includes a first support plate body 340 and a second support plate body 350 connected in opposition, which are fixedly connected on both sides of the transverse push connecting plate. Both the first support plate body 340 and the second support plate body 350 are triangular plate structures, so as to close the gap between the transverse push connecting plate body 320 and the side connecting plate body 330. The bottom end of the first support plate body 340 is fixedly connected to the transverse push connecting plate body 320, and the two side ends of the first support plate body 340 are fixedly connected to the support base plate body 310 and the side connecting plate body 330, respectively. Correspondingly, the bottom end of the second support plate body 350 is fixedly connected to the transverse push connecting plate body 320, and the two side ends of the second support plate body 350 are fixedly connected to the support base plate body 310 and the side connecting plate body 330, respectively. Thus, the transverse push connecting plate body 320, the side connecting plate body 330, the support base plate body 310, the first support plate body 340 and the second support plate body 350 are enclosed into a hollow closed frame structure, thereby further improving the structural strength and load resistance of the support, effectively dispersing and transmitting the load, and improving the structural rigidity and bending resistance.

[0035] Among them, the first support plate body 340 is close to the transverse push between the first support plate body 340 and the second support plate body 350, and the first support plate body 340 is provided with a bent portion 341 bent in a direction away from the transverse push. Thus, when connected with the transverse push, part of the transverse push can be effectively avoided, the compactness of the connection structure is improved, and the bending strength of the support is also increased by the bent portion 341. The overall stability of the support is increased by the bent portion 341, so that it can better resist the action of transverse force and impact force, and plastic deformation or fatigue damage of the support under complex working conditions is avoided. The movement space of the transverse push is ensured, and the connection strength is not affected.

[0036] In addition, the cross-sectional size of the side connecting plate body 330 gradually decreases from the support base plate outward along the extension direction thereof. In the present embodiment, the cross-sectional length of the side connecting plate body 330 gradually decreases from the support base plate body 310 in the extension direction, i.e., the structure is "narrow at the top and wide at the bottom", which helps to reduce the self-weight, while also increasing the connection strength with the support base plate body 310, further improving the stability and load-carrying capacity of the connecting portion.

[0037] In the specific structure of the support base plate body 310, the support base plate body 310 is provided with at least two spaced mounting assemblies in the second direction, each mounting assembly being provided with a plurality of mounting holes 311 uniformly spaced in the third direction, the mounting holes 311 being connected with the axle 100 by a fixing pin body, and the second direction intersecting the third direction. The support base plate body 310 is provided with a positioning pin hole 312 between the two mounting assemblies, which is used at least for positioning and mounting with the axle 100.

[0038] In the present embodiment, the second direction is the length direction of the support base plate body 310, and the third direction is the width direction of the support base plate body 310. In the connection structure of the axle 100, two mounting assemblies are provided on the support base plate body 310, wherein the two mounting assemblies are distributed on the two side ends of the support base plate body 310 in the length direction of the support base plate body 310, and each mounting assembly includes mounting holes 311 uniformly spaced in the width direction of the support base plate body 310. During installation, the fixing pin body passes through the mounting holes 311 and the axle 100, thereby fixedly connecting the support base plate body 310 with the axle 100. The fixing pin body can be a bolt, which ensures the firmness and stability of the connection. In addition, the support base plate body 310 is designed to be thickened to improve its bending and compression resistance, increase structural rigidity, and enhance load-carrying capacity and durability. The support base plate body 310 is provided with a plurality of mounting holes 311 to disperse stress points, thereby improving the strength and anti-deformation capacity of the connection between the support base plate body 310 and the axle 100.

[0039] In addition, the support base plate body 310 is provided with a positioning pin hole 312 at the middle position of the end surface close to the axle 100. The positioning pin hole 312 and the positioning pin on the axle 100 cooperate to quickly determine the relative position of the support base plate body 310 and the axle 100, thereby improving the connection efficiency. The cooperation of the positioning pin and the positioning pin hole 312 can provide additional support and fixation to prevent relative displacement and loosening of the components during operation, thereby enhancing the stability and reliability of the overall structure.
