Description

Technical Field

[0001] This application relates to a crash cushion vehicle, specifically to a two-stage tipping device for a crash cushion vehicle. Background Technology

[0002] Currently, most crash cushioning vehicles suffer from excessively high crash cushions, resulting in high wind resistance during operation. This high wind resistance leads to vehicle instability during maneuvers, increasing driver risk and reducing safety. Therefore, some existing crash cushioning vehicles are equipped with a primary tipping device, where the crash cushion is perpendicular to the ground after tipping, while others have a secondary tipping device, such as the secondary tipping device for a crash cushioning vehicle described in patent number 202220000852.0, where the crash cushion is parallel to the top of the vehicle body after being folded up. However, these secondary tipping structures lack lighting fixtures, which play a crucial role in alerting vehicles approaching from behind. Therefore, this structure is insufficient in alerting vehicles approaching from behind, hindering the improvement of construction vehicle safety. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the technical solution of this utility model is: a two-stage tipping device for a collision buffer vehicle, comprising a body, a connecting seat fixedly installed at the rear of the body, the connecting seat being hinged to a lamp holder seat, a lamp holder fixedly installed on the lamp holder seat, the lamp holder seat being hinged to a collision buffer seat, a collision buffer being fixedly installed on the collision buffer seat, a primary tipping cylinder being provided between the connecting seat and the lamp holder seat, and a secondary tipping cylinder being provided between the lamp holder seat and the collision buffer seat.

[0004] In order to better limit the rotation stroke of the lamp holder when the lamp holder is erected, a buffer column is fixedly installed on the connecting seat, and a limiting plate that cooperates with the buffer column is installed on the lamp holder.

[0005] To better limit the flipping stroke of the anti-collision bag holder when it is lowered, a limit post is inclinedly provided on the anti-collision bag holder. When the lamp holder is perpendicular to the ground, the limit post contacts the inner surface of the lamp holder holder.

[0006] The beneficial effects of this utility model are:

[0007] 1. This utility model features a lamp holder base, which allows the lamp holder and the anti-collision bag to be flipped and folded together during operation, reducing wind resistance and improving vehicle safety. Simultaneously, the lamp holder better alerts vehicles approaching from behind during operation, further enhancing the safety of construction vehicles.

[0008] 2. This utility model is equipped with limiting posts and buffer posts, which not only limit the lamp holder and anti-collision bag seat, but also play a partial buffering role when receiving vehicle impact. Attached Figure Description

[0013] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0014] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0015] exist Figures 1 to 2 Among them, a two-stage tipping device for a collision buffer vehicle includes a body 1, a connecting seat 2 fixedly installed at the rear of the body 1, the connecting seat 2 being hinged to a lamp holder seat 3, a lamp holder 4 fixedly installed on the lamp holder seat 3, the lamp holder seat 3 being hinged to a collision protection bag seat 5, a collision protection bag 6 fixedly installed on the collision protection bag seat 5, a primary tipping cylinder 8 being provided between the connecting seat 2 and the lamp holder seat 3, and a secondary tipping cylinder 7 being provided between the lamp holder seat 3 and the collision protection bag seat 5.

[0016] Furthermore, a buffer post 9 is fixedly provided on the connecting seat 2, and a limiting plate 10 that cooperates with the buffer post 9 is provided on the lamp holder seat 3.

[0017] Furthermore, a limit post 11 is inclinedly provided on the anti-collision bag 5.

[0018] During operation, the piston end of the first-stage tilting cylinder 8 retracts, pulling the lamp holder 3 to rotate clockwise around its hinge point with the connecting seat 2. When the lamp holder 3 is in a horizontal state, the buffer column 9 contacts the limiting plate 10, which can better limit the lamp holder 3 and prevent damage to the first-stage tilting cylinder 8 when the lamp holder 3 is in a horizontal state for a long time. At this time, the piston end of the second-stage tilting cylinder 7 retracts, and the anti-collision bag 5 rotates clockwise around its hinge point with the lamp holder 3 until the anti-collision bag 6 is level with the ground. At this time, the limiting column 11 contacts the inner surface of the lamp holder 3, which can limit the anti-collision bag 5 and prevent damage to the second-stage tilting cylinder 7.

[0019] When retracting the light fixture 4 and the anti-collision bag 6, first open the secondary tilting cylinder 7 until the anti-collision bag 6 is perpendicular to the ground. Then, open the primary tilting cylinder 8 until the light fixture 4 and the anti-collision bag 6 are directly above the compartment. This achieves the purpose of tilting and retracting the light fixture 4 and the anti-collision bag 6 together.

[0020] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
