Description

Technical Field

[0001] The utility model belongs to the technical field of trailer anti-collision, and in particular relates to a high-safety trailer side anti-collision buffer structure. Background Art

[0002] A trailer is an impact object towed by a car but without its own power drive device. It is a combination of a car (truck or tractor, forklift) and one or more trailers.

[0003] Generally, when a trailer is hit on the side, due to the high height of the trailer, the impacting object may be squeezed into the bottom of the trailer, which will increase the degree of damage caused by the accident and increase the difficulty of rescue. Therefore, a high-safety trailer side anti-collision buffer structure is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a highly safe trailer side anti-collision buffer structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-safety trailer side anti-collision buffer structure, including a vehicle body and an anti-collision block, the anti-collision block is fixedly connected to the vehicle body, the front side of the anti-collision block is an inclined surface, two displacement grooves are provided on the inclined surface, the interiors of the two displacement grooves are fixedly connected with sliding rods, the exteriors of the two sliding rods are slidably connected with sliders, the two sliders are slidably connected in the two displacement grooves, the exteriors of the two sliding rods are sleeved with springs, the two sliders are commonly fixedly connected with a buffer block, and the back side of the buffer block slides obliquely on the inclined surface.

[0006] By setting anti-collision blocks and buffer blocks, when an impact object hits the side of the vehicle body, it will first be guided and blocked by the buffer block. After the buffer block is subjected to the impact force, it will be obliquely set on the inclined surface, so that the buffer block will slide obliquely upward. During this period, when the buffer block slides obliquely upward, it will drive the slider to slide in the displacement groove, and the slider will squeeze the spring, so that the impact force received by the buffer block is converted into an upward buffering force to a certain extent, and the compression of the spring helps to enhance the buffering effect. After that, the impact object will be blocked by the anti-collision block. Due to the buffering and obstruction, it is difficult for the impact object to get stuck in the bottom of the vehicle body at this time, which helps to ensure the safety of people inside the impact object.

[0007] As a preferred implementation, one end of the spring is fixedly connected in the displacement slot, and the other end of the spring is fixedly connected to the slider.

[0008] As a preferred implementation manner, a guide surface is provided on the lower surface of the buffer block.

[0009] As a preferred embodiment, two roller grooves are opened on the front side of the buffer block, and guide rollers are rotatably connected in the two roller grooves. The two guide rollers are located above the guide surface, and the two guide rollers are fixedly connected with pulleys at the rotation point at one end of the roller grooves, and a transmission belt is arranged between the two pulleys.

[0010] As a preferred implementation, a connection block is fixedly connected to one side of the buffer block, and a driving motor is fixedly connected to the lower surface of the connection block.

[0011] As a preferred implementation, the output shaft of the driving motor is fixedly connected to one side of the upper pulley.

[0012] By setting a driving motor, when the driving motor is started, the pulley is driven to rotate through the transmission belt, and the pulley drives the guide roller to rotate, so that when the impact object hits the buffer block, it will be guided upward by the arc surface of the guide surface, and then the impact object can be guided to the guide roller and guided by the upward rotation, thereby reducing the possibility of the impact object drilling into the bottom of the vehicle body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides an anti-collision block and a buffer block. When an impact object hits the side of the vehicle body, it will first be guided and blocked by the buffer block. After the buffer block is subjected to the impact force, the buffer block will slide obliquely upwards through the oblique setting on the inclined surface. During the period, the buffer block will drive the sliding block to slide in the displacement groove when sliding obliquely upwards, and the sliding block will squeeze the spring, so that the impact force received by the buffer block is converted into an upward buffering force to a certain extent, and the compression of the spring helps to enhance the buffering effect. Thereafter, the impact object will be blocked by the anti-collision block. Due to the buffering and obstruction, it is difficult for the impact object to be stuck in the bottom of the vehicle body at this time, thereby helping to ensure the safety of people inside the impact object.

[0015] The utility model provides a driving motor. When the driving motor is started, the transmission belt drives the pulley to rotate, and the pulley drives the guide roller to rotate, so that the impact object will be guided upward by the arc surface of the guide surface after hitting the buffer block, and then the impact object can be guided to the guide roller and guided by the upward rotation, thereby reducing the possibility of the impact object drilling into the bottom of the vehicle body.
