In order to further improve the overall lightweight degree, the patent opens lightweight holes in the reinforced body part to further reduce the overall weight. However, there is still room for improvement in the actual use of the patent. The lightweight degree obtained by opening a small number of lightweight holes is not high. When a large number of lightweight holes are opened, since there is no supporting structure inside the lightweight hole, the load-bearing capacity of the lightweight hole part will be weakened during actual use, affecting the use of the thrust rod. In this regard, the present application provides a high-load-bearing thrust rod to solve the above problems. Utility Model Content

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] See also Figure 1-3The present application provides a technical solution: a high-load-bearing thrust rod, comprising a composite rod body 1, with ball joint assemblies 200 for connecting vehicle components installed at both ends of the composite rod body 1, and a load-bearing assembly 300 for achieving a lightweight effect installed on the outer side of the composite rod body 1; by using the load-bearing assembly 300 on the outer side of the composite rod body 1, the overall lightweight degree can be further improved while also giving the thrust rod a high-load-bearing characteristic, and the overall weight of the thrust rod is greatly reduced by slotting, and the support portion of the thrust rod is formed into a shape similar to an I-beam, so that the overall high-load-bearing and strength characteristics are maintained, and at the same time, by arranging an auxiliary support structure in the groove, the overall tensile strength and load-bearing resistance of the thrust rod are further improved, thereby ensuring the overall lightweight while also having the advantage of high load-bearing.

[0030] In this embodiment, the bearing assembly 300 is a structure used to improve the overall lightweightness and bearing capacity.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, the bearing assembly 300 includes a strong rod 301 that passes through and is fixed inside the composite rod body 1, a plurality of support blocks 302 that are fixed to the outside of the composite rod body 1 and are symmetrically distributed up and down, two lightweight slots 303 opened on the outside of the composite rod body 1, a plurality of fixed blocks 304 fixed to the inner sides of the lightweight slots 303 and each two form a group, a bearing lifting rod 305 fixed between opposite sides of the two fixed blocks 304 in the same group, and a plurality of auxiliary rods 306 fixed between opposite sides of the two fixed blocks 304 in the same group.

[0032] It should be noted that the two lightweight slots 303 are symmetrically distributed up and down, which can allow the pressure to be evenly transmitted. There are six groups of fixed blocks 304 inside each lightweight slot 303, and the opposite sides of the top and bottom fixed blocks 304 are respectively fixedly connected to the inner side of the corresponding lightweight slot 303, so that the two corresponding fixed blocks 304 in the same group cooperate with the load-bearing lifting rod 305 to share the transmitted pressure, thereby achieving the effect of auxiliary load bearing.

[0033] In addition, there are two auxiliary rods 306 between the opposite sides of the two fixed blocks 304 in the same group, and the corresponding two auxiliary rods 306 are symmetrically distributed with the corresponding load-bearing lifting rod 305 as the center. Two load-bearing spaces can be formed between the two fixed blocks 304 in the same group and the load-bearing lifting rod 305. The auxiliary rods 306 are distributed diagonally inside the corresponding load-bearing space, so that the auxiliary rods 306 can divide the square load-bearing space into two triangles, thereby utilizing the stable characteristics of the triangle to provide auxiliary support for the load-bearing lifting rod 305, thereby achieving the effect of improving the overall load-bearing performance.

[0034] In this embodiment, the ball joint assembly 200 is a structure for connecting a thrust rod to a vehicle component.

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, the ball joint assembly 200 includes a ball joint 201 fixedly mounted on the end of the composite rod body 1, a rubber metal ball joint 202 movably mounted inside the ball joint 201, and two ball joint connection blocks 203 respectively fixed at both ends of the rubber metal ball joint 202.

[0036] It should be noted that a hinge cavity is provided inside the ball joint 201 for installing the rubber metal ball joint 202, and the top and bottom of the hinge cavity are both open. The rubber metal ball joint 202 has an oval shape that is wide in the middle and narrow at both ends. Specifically, the rubber metal ball joint 202 consists of a spherical block and two arc-shaped blocks fixed on both sides of the spherical block, so that the rubber metal ball joint 202 can move inside the hinge cavity, realizing the movable characteristics of the ball joint.

[0037] In addition, a connection hole is provided on the left side of the ball joint connection block 203, and the connection hole can be used for connecting parts such as bolts to be inserted, so that vehicle components can be connected and fixed to the ball joint connection block 203. The two ends of the strong rod 301 respectively pass through the two ends of the composite rod body 1, and the two ends of the strong rod 301 are respectively fixedly connected to the opposite sides of the two ball joints 201, so that the strong rod 301 can play the role of central support. Among them, the strong rod 301 is a high-strength steel structure component such as martensitic steel, and the composite rod body 1 is a rod body made of magnesium alloy, which has the characteristics of high strength and high lightness. It can also be made of nano-composite materials instead of magnesium alloy, and similarly, it also has the characteristics of high strength and high lightness.

[0038] At the same time, there are eight support blocks 302 , and the opposite sides of the left and right support blocks 302 are fixedly connected to the opposite sides of the two ball joints 201 respectively, so that the support blocks 302 can play an auxiliary supporting role for the ball joints 201 .

[0039] The working principle of the above embodiment is:

[0040] When the high-load-bearing thrust rod is in use, the two lightweight grooves 303 are provided on its surface, so that the overall weight of the composite rod body 1 is effectively reduced, and the shape of the composite rod body 1 from left to right or from front to back is an I-shape, so that the composite rod body 1 has the characteristics of high load-bearing and high strength. At the same time, under the action of the strong rod 301, it can play a very strong central supporting role for the composite rod body 1, further improving the overall strength. An I-shape can be formed between the two fixed blocks 304 corresponding to the inner side of the lightweight groove 303 and the load-bearing lifting rod 305, so that the load-bearing pressure and bending pressure can be shared and supported. Under the cooperation of the auxiliary rod 306, the space between the structures can form a triangle, so that the load-bearing capacity and anti-bending ability are further improved, so that the thrust rod has the advantages of high load-bearing, high strength and strong anti-bending ability.

[0041] Compared with the prior art, the high-load-bearing thrust rod, through the use of the load-bearing component 300 on the outer side of the composite rod body 1, can further improve the overall lightweight degree while also making the thrust rod have the characteristics of high load-bearing. The overall weight of the thrust rod is greatly reduced by using slots, and the support portion of the thrust rod is formed into a shape similar to an I-beam, so that the overall high load-bearing and strength characteristics are maintained. At the same time, by arranging an auxiliary support structure in the groove, the overall tensile and load-bearing resistance of the thrust rod are further improved, thereby ensuring the overall lightweight while also having the advantage of high load-bearing, solving the shortcomings of the existing lightweight thrust rods that the overall lightweight degree is not high and there is a certain room for improvement.
