Description

Technical Field

[0001] The invention relates to the technical field of vehicle side protection barriers, in particular to a vehicle side protection barrier with adjustable height. Background Art

[0002] With the continuous development of automobile technology and the increase in the number of automobiles, people's requirements for the safety of various types of automobiles have also increased. For large vehicles, due to the high chassis of large vehicles, it is mandatory to install side guardrails. This is to prevent unprotected road users from falling into the side of the vehicle and being rolled under the wheels. In addition, relevant national laws and regulations also have strict regulations on the ground clearance of side guards, which are usually required to be between 300mm and 550mm. Since the ground clearance of chassis of various large vehicles of different models is different, and the structure of existing side guards is fixed and the height cannot be adjusted, it is necessary to design the side guards separately according to the chassis height parameters of each type of vehicle, resulting in the poor versatility of side guardrails. In this regard, the authorization announcement number is Chinese invention patent CN110065460A discloses an adjustable side protection device for a semitrailer and a semitrailer thereof, which includes: two groups of side protection components, which are connected by a mounting crossbeam, and the mounting crossbeam is mounted on the bottom of the semitrailer body; each group of side protection components includes: a longitudinally arranged connecting bracket, the outer side of the connecting bracket is connected to a side protection crossbeam, the connecting bracket is provided with more than two groups of positioning holes with different horizontal heights, and the end of the mounting crossbeam is fixed to a group of positioning holes of the connecting bracket: by providing a plurality of groups of positioning holes with different heights on the connecting bracket of the side protection crossbeam, by selecting one group of positioning holes to be fixed with the mounting crossbeam, the side protection crossbeam can be adjusted in height from the ground; however, this adjustment method has certain limitations:

[0003] This adjustment method can only adjust the overall height of the side guardrail. Although it can meet the height requirement from the ground, the distance between the top of the side guardrail and the vehicle chassis will also be affected. Especially when the vehicle chassis is high, the distance between the top of the side guardrail and the vehicle chassis will be larger. Unprotected road users can easily be drawn under the chassis of large vehicles at this distance, causing the side guardrail to lose its protective effect.

[0004] For this reason, we propose a vehicle side guardrail with adjustable height to solve the above problems. Summary of the invention

[0047] Embodiment 3:

[0048] See also Figure 1-11 , which is the third embodiment of the present invention. This embodiment is based on the above three embodiments. When the present invention is installed, the top plate 22 in the mounting structure 2 is installed on the vehicle chassis. When the overall height of the external guardrail structure 1 is adjusted, the upper column 243 and the lower column 244 are changed in position by lifting or lowering. After completion, a long rod 248 is inserted into the end block 241 and connected to the first hexagonal nut 2411 for fixing, so that the bottom of the external guardrail structure 1 is at a suitable height from the ground. If the height of the entire external guardrail structure 1 needs to be adjusted, the first bolt 137 and the second bolt 148 need to be loosened, and then the height of the upper protective strip 11 and the lower protective strip 12 are adjusted separately. Similarly, the upper column 243 and the lower column 244 will change their positions. After completion, the long rod 248 is also inserted into the end block 241 and connected to the first hexagonal nut 2411 for fixing. The hexagonal nut 2411 is used to fix, and then the first bolt 137 and the second bolt 148 are tightened; the relative positions of the upper protective strip 11 and the lower protective strip 12 in the outer guardrail structure 1 of the present invention can be adjusted, so as to change the overall height of the entire outer guardrail structure 1. During adjustment, the upper column 243 in the longitudinal adjustment component 24 can change the height of the upper protective strip 11, and the lower column 244 can change the height of the lower protective strip 12. In this way, not only can the height of the entire outer guardrail structure 1 be adjusted by sliding up and down, but also the height position of the upper protective strip 11 and the lower protective strip 12 can be adjusted separately. In this way, not only can the ground height of the outer guardrail structure 1 be guaranteed to meet the requirements, but also the distance between the upper part of the outer guardrail structure 1 and the vehicle chassis can be adjusted to a suitable position, thereby ensuring the protective performance of the outer guardrail structure 1.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
