[0040] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Physical quantities in formulas, if not separately marked, should be understood as basic quantities of the base units of the International System of Units, or derived quantities derived from the basic quantities through mathematical operations such as multiplication, division, differentiation or integration.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] like Figure 1 As shown, the side window anti-collision guardrail provided by the embodiment of the present invention includes: a foot piece 001, a support tube 002, a connecting piece 003, an embedded piece 004 and a guardrail tube 005; the embedded piece 004 extends along the radial direction of the guardrail tube 005 and is connected to the inside of the guardrail tube 005; the support tube 002 is perpendicular to the guardrail tube 005, and the support tube 002 is supported between the foot piece 001 and the guardrail tube 005; the foot piece 001 and the embedded piece 004 are connected by the connecting piece 003.

[0044] The embedded part 004 is connected to the connecting part 003, and the connecting part 003 squeezes the foot piece 001 and pulls the embedded part 004, so that the support tube 002 is pressed between the foot piece 001 and the guardrail pipe 005. There is no need to directly weld the guardrail pipe 005, so overheating damage to the guardrail pipe 005 and related components can be avoided.

[0045] In the embodiment of the present invention, the outer surface of the guardrail pipe 005 is provided with a spray-coated layer with a thickness of 0.15 mm to 0.25 mm.

[0046] In addition, the outer sleeve of the guardrail pipe fitting 005 is provided with an anti-collision sponge 006. Under the condition that the guardrail pipe fitting 005 does not need to be welded and fixed, the anti-collision sponge 006 is sleeved on the guardrail pipe fitting 005, and there is no need to worry about damage to the anti-collision sponge 006 due to overheating.

[0047] like Figure 1 and Figure 2 As shown, the foot piece 001, the support tube 002, the connector 003 and the embedded part 004 constitute a connecting component, and a plurality of connecting components are arranged at intervals along the guardrail tube 005. As the length of the guardrail tube 005 increases, the number of connecting components can be increased.

[0048] like Figure 2 and Figure 3 As shown, the guardrail pipe 005 is provided with a hit bent section, which is located between any two adjacent connecting components; taking one circumferential side of the guardrail pipe 005 as the outer side, the inner wall thickness of the hit bent section is greater than the outer wall thickness.

[0049] When the outside is hit, the outer wall of the guardrail pipe 005 is depressed and bent by the force, thereby producing a buffering effect. In addition, under the protection of the inner wall with a larger wall thickness, the inner wall of the guardrail pipe 005 can be prevented from breaking and forming a sharp fracture.

[0050] like Figure 4 and Figure 6 As shown, the outer inner wall of the hit curved section is connected with a reinforcing rib 007, and the reinforcing rib 007 extends along the axial direction of the guardrail pipe 005. The outer inner wall of the hit curved section is connected by the reinforcing rib 007, thereby improving the structural strength of the hit curved section and increasing the bending resistance of the hit curved section.

[0051] like Figure 5 As shown, the reinforcing rib 007 is provided with a plurality of breakable cuts 701, and the plurality of breakable cuts 701 are arranged at intervals along the axial direction of the guardrail pipe 005. When subjected to an external impact, the reinforcing rib 007 can form fractures at the plurality of breakable cuts 701, respectively, so that the bend of the guardrail pipe 005 will also be generated at the plurality of breakable cuts 701 at the same time, thereby the guardrail pipe 005 between any two adjacent connection components will form an arc bend, which can avoid the guardrail pipe 005 from being broken due to excessive concentration of bending positions.

[0052] like Figure 7 As shown, the reinforcing rib 007 includes: a first rib 710, a second rib 720 and a third rib 730; the first rib 710, the second rib 720 and the third rib 730 are arranged at intervals along the circumference of the guardrail pipe 005 and are respectively welded to the outer inner wall of the impacted bending section; and the first rib 710, the second rib 720 and the third rib 730 are each provided with a breakable cut mark 701.

[0053] Among them, the easy-to-break cuts 701 on the first rib 710, the second rib 720 and the third rib 730 are spaced apart along the guardrail pipe 005, and the depth of the easy-to-break cuts 701 on the second rib 720 is greater than the depth of the easy-to-break cuts 701 on the first rib 710 and the third rib 730. When subjected to an external impact, the easy-to-break cuts 701 on the second rib 720 break first, followed by the easy-to-break cuts 701 on the first rib 710 and the third rib 730, thereby achieving the weakening and bending of the guardrail pipe 005 at a specific position in the middle and then at both sides, thereby avoiding the guardrail pipe 005 from increasing safety hazards due to irregular bending and breaking.

[0054] like Figure 8 As shown, in an optional embodiment, the side wall of the support tube 002 is provided with an oblique cut 201 extending in the circumferential direction, and the oblique cut 201 is inclined from the outside to the inside in a direction away from the leg piece 001.

[0055] When the outer side is hit, the foot piece 001 is squeezed toward the direction close to the guardrail pipe fitting 005. The impact force can cause the oblique cut 201 to break, and the outer section of the support pipe 002 will be inserted into the inner broken pipe along the oblique cut 201. On the one hand, it can form a shrinkage and give way, and on the other hand, the friction between the inner and outer broken pipes can slow down the transmission of the collision impact to the guardrail pipe fitting 005.

[0056] In an optional embodiment, the foot piece 001 is connected to the support tube 002 by welding, thereby ensuring that the relative position of the foot piece 001 and the support tube 002 is stable.

[0057] like Fig. 9 As shown, in another optional embodiment, a limiting protrusion 202 for abutting against the guardrail pipe 005 is provided inside the support tube 002 .

[0058] Among them, the limiting protrusion 202 can be formed by bending the end of the support tube 002 inward, or a convex ring can be used to fit the inner wall of the support tube 002 through a thread, and the limiting protrusion 202 can abut against the guardrail pipe fitting 005, thereby increasing the supporting contact area of ​​the guardrail pipe fitting 005 and improving the stability of the guardrail pipe fitting 005.

[0059] In an optional embodiment, a filler may be provided inside the support tube 002, and the filler is filled between the guardrail tube 005 and the foot piece 001. The filler filling ensures that the support tube 002 and the connecting piece 003 are nearly coaxial on the one hand, and on the other hand, the filler is supported between the guardrail tube 005 and the foot piece 001, and a certain supporting effect can still be provided when the support tube 002 is damaged due to impact.

[0060] like Figure 1 , Figure 8 and Fig. 9 As shown, the side window anti-collision guardrail assembly method provided by the embodiment of the present invention includes the following steps:

[0061] The inner insert 004 is extended along the radial direction of the guardrail pipe 005, and the inner insert 004 is connected to the inside of the guardrail pipe 005;

[0062] Make the support tube 002 perpendicular to the guardrail tube 005, and make the support tube 002 supported between the guardrail tube 005 and the foot piece 001;

[0063] The foot piece 001 is connected to the embedded part 004 by using the connecting part 003 .

[0064] The side window anti-collision guardrail assembly method described in this embodiment is used to process and form the side window anti-collision guardrail described in the above embodiment. In addition, the vehicle provided in the embodiment of the present invention is equipped with the side window anti-collision guardrail described in the above embodiment. The assembly method and the vehicle both have the beneficial effects of the side window anti-collision guardrail, which will not be repeated here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
