[0029] Commercial vehicle bumper guards, also known as anti-collision beams or crash bars, are important safety devices at the front and rear of vehicles. Their primary function is to protect the vehicle and reduce damage in the event of a collision, while also providing other functions. Traffic regulations in many countries and regions require commercial vehicles to be equipped with standard-compliant bumper guards to ensure vehicle safety and compliance. Existing bumper guards are fixed to the vehicle frame, making it impossible to adjust their distance from the ground. This can reduce the vehicle's passability in certain adverse road conditions. Furthermore, when the driver changes the vehicle's tire size, the distance between the bumper guard and the ground changes, causing the bumper height to fail to meet regulatory requirements.

[0030] To solve the above-mentioned technical problems, this application provides a commercial vehicle guardrail 100.

[0031] Reference Figure 1 , Figure 2 As shown, this application embodiment provides a commercial vehicle guardrail 100, including a protective crossbar 101 and a height adjustment assembly; the height adjustment assembly includes a lower bracket connector 102 connected to the protective crossbar 101 and an upper bracket connector 103 for connecting to the commercial vehicle frame; the upper bracket connector 103 and the lower bracket connector 102 are connected by a sliding guide structure, and the lower bracket connector 102 is driven by the sliding guide structure to move the protective crossbar 101 closer to or away from the upper bracket connector 103, thereby adjusting the distance between the protective crossbar 101 and the ground.

[0032] It should be noted that the protective crossbar 101 extends horizontally, meaning it is parallel to the horizontal plane. The upper bracket connector 103 connects to the commercial vehicle frame, while the lower bracket connector 102 connects to the protective crossbar 101. The upper bracket connector 103 and the lower bracket connector 102 can be manufactured using stamping or other production processes.

[0033] It should be noted that the commercial vehicle guard bar 100 in this application embodiment can be used as a front guard bar or a rear guard bar for commercial vehicles, and those skilled in the art can make the necessary adjustments as needed.

[0034] It should be noted that the height adjustment assembly in this embodiment consists of an upper support connector 103 and a lower support connector 102. The upper support connector 103 and the lower support connector 102 are connected by a sliding guide structure, and the guide path of the sliding guide structure is perpendicular to the horizontal ground. Therefore, pushing the lower support connector 102 upwards, guided by the sliding guide structure, allows the protective crossbar 101 to move upwards. Pushing the lower support connector 102 downwards, guided by the sliding guide structure, allows the protective crossbar 101 to move downwards.

[0035] The commercial vehicle guardrail 100 provided in this application embodiment includes a protective crossbar 101 and a height adjustment component; the height adjustment component includes a lower bracket connector 102 connected to the protective crossbar 101 and an upper bracket connector 103 for connecting to the commercial vehicle frame; the protective crossbar 101 in this application embodiment can be adjusted up and down through the height adjustment component to achieve flexible adjustment of the distance between the protective crossbar 101 and the ground.

[0036] In this embodiment of the application, the upper support connector 103 and the lower support connector 102 are connected by a sliding guide structure. Under the action of the sliding guide structure, the lower support connector 102 drives the protective crossbar 101 to move closer to or away from the upper support connector 103, thereby adjusting the distance between the protective crossbar 101 and the ground.

[0037] Compared to existing technologies, the height-adjustable commercial vehicle bumper 100 provided in this application embodiment allows for flexible adjustment of the bumper height as needed. Therefore, this application embodiment enhances vehicle passability and ensures that the bumper height meets regulatory requirements after changing to different tire sizes.

[0038] Reference Figure 3 As shown, as an optional implementation, the sliding guide structure includes a guide groove 104 provided on the upper bracket connector 103, and a plug-in portion 105 on the lower bracket connector 102. The plug-in portion 105 is inserted into the guide groove 104 in a vertical direction. A locking assembly is provided between the plug-in portion 105 and the upper bracket connector 103 to prevent the plug-in portion 105 from moving within the guide groove 104.

[0039] It should be noted that the sliding guide structure in this application embodiment includes a guide groove 104 and an insertion part 105.

[0040] In the above embodiment, a guide groove 104 is formed on the upper bracket connector 103, and a plug-in portion 105 is formed on the lower bracket connector 102. If necessary, plug-in portions 105 may also be formed on the upper and lower parts of the upper bracket connector 103, and guide grooves 104 may be formed on the lower bracket connector 102.

[0041] In this embodiment, the guide groove 104 is arranged perpendicular to the horizontal plane, and the insertion part 105 can slide up and down in the guide groove 104 so that the height of the protective crossbar 101 can be adjusted.

[0042] It should be noted that, in this embodiment, a locking assembly is provided on the insertion part 105 and the upper bracket connector 103 to lock the insertion part 105 within the guide groove 104, preventing the lower bracket connector 102 and the upper bracket connector 103 from moving away from each other under gravity. The locking assembly ensures that the protective crossbar 101 can be stably installed after height adjustment, thus improving the stability of the protective crossbar 101.

[0043] Reference Figure 3 , Figure 4 As shown, as an optional implementation, the upper bracket connector 103 includes a first U-shaped structure 106, the opening direction of the first U-shaped structure 106 is consistent with the extension direction of the protective crossbar 101; a guide groove 104 is formed in the first U-shaped structure 106.

[0044] Furthermore, the upper bracket connector 103 in this embodiment includes a first U-shaped structure 106, that is, the transverse joint surface of the guide groove 104 is a U-shaped structure. The opening direction of the first U-shaped structure 106 is consistent with the extension direction of the protective crossbar 101, and the insertion part 105 can slide up and down within the first U-shaped structure 106.

[0045] Furthermore, refer to Figure 3 , Figure 5 As shown, the plug-in part 105 includes a second U-shaped structure 107; a first U-shaped structure 106 is sleeved on the outside of the second U-shaped structure 107; the locking assembly includes a first connector 108, which extends through the bottom of the second U-shaped structure 107 and the bottom of the first U-shaped structure 106 along the extension direction of the protective crossbar 101, and abuts the bottom of the second U-shaped structure 107 with the bottom of the first U-shaped structure 106.

[0046] The locking assembly of this application embodiment includes a first connector 108, wherein the first connector 108 may be a bolt or a quick-release pin. This application embodiment achieves locking of the upper bracket connector 103 and the lower bracket connector 102 by connecting the bottom of the first U-shaped structure 106 and the second U-shaped structure 107.

[0047] It should be noted that in this embodiment, the upper support connector 103 is configured as a first U-shaped structure 106 and the lower support connector 102 is configured as a second U-shaped structure 107. This not only reduces the weight of the upper support connector 103 and the lower support connector 102, but also effectively enhances the structural strength of the upper support connector 103 and the lower support connector 102.

[0048] As an optional implementation, the locking assembly includes a second connector 109, which penetrates the sidewall of the second U-shaped structure 107 and the sidewall of the first U-shaped structure 106 in a direction perpendicular to the protective crossbar 101, and abuts the sidewall of the second U-shaped structure 107 with the sidewall of the first U-shaped structure 106.

[0049] Furthermore, the locking assembly in this application embodiment also includes a second connector 109. Similarly, the second connector 109 may be a bolt or a quick-release pin.

[0050] In this embodiment of the application, the bottom surface and both sides of the first U-shaped structure 106 and the second U-shaped structure 107 are in close contact, so that the upper bracket connector 103 and the lower bracket connector 102 have a large contact surface, thereby improving the stability of the upper bracket connector 103 and the lower bracket connector 102.

[0051] In this embodiment, a first connector 108 connects the bottom surfaces of the first U-shaped structure 106 and the second U-shaped structure 107, and a second connector 109 connects the two sides of the first U-shaped structure 106 and the second U-shaped structure 107, so that the lower support connector 102 and the upper support connector 103 can be reliably connected.

[0052] Reference Figure 3 As shown, in one optional implementation, the locking assembly includes a third U-shaped structure 110 with its opening facing the upper bracket connector 103, and the inner walls on both sides of the third U-shaped structure 110 contact the outer walls on both sides of the first U-shaped structure 106 respectively; the second connector 109 passes through the side walls of the third U-shaped structure 110, the side walls of the first U-shaped structure 106 and the side walls of the second U-shaped structure 107 in sequence.

[0053] Furthermore, refer to Figure 3 , Figure 4 As shown, in this embodiment, the upper support connector 103 and the lower support connector 102 are reinforced by the provision of a third U-shaped structure 110, with the opening of the third U-shaped structure 110 facing the first U-shaped opening. This ensures that the side of the third U-shaped structure 110 is in close contact with the side of the first U-shaped structure 106, with a distance between their bottoms. This embodiment effectively enhances the stability of the connection between the upper support connector 103 and the lower support connector 102 through the above-described arrangement.

[0054] Reference Figure 4 As shown, as an optional implementation, the bottom of the first U-shaped structure 106 is provided with a plurality of first locking holes 111 arranged at intervals along the extension direction of the guide groove 104, and the locking assembly passes through the first locking holes 111.

[0055] For example, there are three sets of first locking holes 111 spaced apart along the extension direction of the guide groove 104. The first connector 108 can be inserted into the first locking holes 111. The vertical distance between two adjacent sets of first locking holes 111 is 5-10 cm.

[0056] It should be noted that each group of first locking holes 111 can be provided with two first locking holes 111 side by side.

[0057] For example, there are four or five sets of first locking holes 111 arranged at intervals along the extension direction of the guide groove 104. The vertical spacing between adjacent first locking holes 111 can be set as needed by those skilled in the art, and is not particularly limited thereto.

[0058] It should be noted that the vertical spacing between adjacent first locking holes 111 is the amount of change that can be made to adjust the height of the protective crossbar 101 in a single operation.

[0059] Reference Figure 4 As shown, as an optional implementation, the sidewall of the first U-shaped structure 106 is provided with multiple sets of second locking holes 112 arranged at intervals along the extension direction of the vertical guide groove 104, and the locking assembly passes through the second locking holes 112.

[0060] Furthermore, in this embodiment of the application, the second locking hole 112 corresponds one-to-one with the first locking hole 111 in the vertical direction, so that the third U-shaped structure 110 can achieve connection locking at different heights.

[0061] Reference Figure 2 As shown, as an optional implementation, a connecting plate 113 is provided on the protective crossbar 101, and two sets of nuts are provided on the connecting plate 113 at intervals along the extension direction of the protective crossbar 101; bolts connected to the nuts are provided on the lower bracket connector 102.

[0062] It should be noted that, in this embodiment of the application, the protective crossbar 101 can be detachably connected to the lower bracket connector 102 by the setting of the connecting plate 113. When the front lower protective crossbar 101 assembly is damaged and needs to be replaced during the driver's use of the vehicle, only the front lower protective crossbar 101 assembly needs to be replaced, and the front lower protective left and right bracket assemblies do not need to be replaced, which saves maintenance costs. At the same time, the bolt connection is convenient and efficient to install.

[0063] As an optional implementation, there are two height adjustment components, which are spaced apart along the extension direction of the protective crossbar 101.

[0064] The present application embodiment improves the stability of the protective crossbar 101 by setting two height adjustment components.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
