Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-collision buffer pads, in particular to an anti-deflection vehicle-mounted anti-collision buffer pad. Background Art
[0002] The anti-collision buffer vehicle has a flippable anti-collision buffer pad installed on the vehicle body. During construction or emergency, the anti-collision buffer vehicle can be parked at the rear of the site and the anti-collision buffer pad can be flipped to a horizontal state to protect on-site workers and equipment, and to remind and protect the rear passengers. Due to its very good performance, it is favored by customers.
[0003] The anti-collision cushion is mainly composed of a base and an energy absorption box. The base is used to connect to the vehicle body, and the energy absorption box is used to absorb energy and prevent collision. Most of the anti-collision cushions currently used do not have guiding and limiting measures. When they are hit, the concave part and the concave shape are affected by the collision part and the shape of the collision vehicle. When the collision position of the vehicle is not at the center position behind the anti-collision cushion, the anti-collision cushion will quickly dent on one side of the collision position, while the other side will not dent or the dent degree will be small. The collision vehicle is prone to turn due to resistance. When the vehicle collision does not stop in time, it will hit the surrounding guardrails or the vehicles and pedestrians next to it, which is very dangerous. In addition, in the actual collision process, the rear driver will unconsciously turn when he finds an obstacle in front. Therefore, most collisions occur on one side of the anti-collision cushion. Therefore, it is very common for the collision vehicle to turn due to resistance and cause a secondary collision. In order to reduce the damage caused by the secondary collision, our company has designed and proposed a new type of anti-deflection vehicle-mounted anti-collision cushion. Utility Model Content
[0004] In view of the shortcomings of the prior art, the utility model provides an anti-deflection vehicle-mounted anti-collision cushion, which is used to solve the problem that the anti-collision cushions currently circulating on the market do not have guiding and limiting measures, which can easily cause the colliding vehicle to turn due to resistance, resulting in a secondary collision and further causing injuries.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0006] A deflection-resistant vehicle-mounted anti-collision buffer pad comprises a base connected to a vehicle body, an energy-absorbing box fixed to a side of the base away from the vehicle body, and a top plate arranged on a side of the energy-absorbing box away from the base, two groups of support rods are arranged between the base and the top plate, the two groups of support rods are respectively mounted on the upper surface and the lower surface of the energy-absorbing box, an anti-collision steel plate parallel to the base is vertically arranged inside the energy-absorbing box, both sides of the top and the bottom of the anti-collision steel plate opposite to the base are horizontally fixedly connected with a slide seat, scissors are horizontally arranged at positions near the top and the bottom of the inner wall of the energy-absorbing box, eight ends of the scissors are respectively slidably connected to the slide seats at corresponding positions, and the interior of the energy-absorbing box is filled with energy-absorbing honeycomb core panels at the side of the anti-collision steel plate close to the vehicle body and the side away from the vehicle body.
[0007] Preferably, a load-bearing beam hinge seat and a flip push rod hinge seat for connecting with the vehicle body load-bearing beam and the flip push rod are fixedly connected above and below the base respectively.
[0008] Preferably, taillights are provided on both sides of the top plate.
[0009] Preferably, the width of the anti-collision steel plate is matched with the width of the energy absorption box, the central rotation axis of the scissors fork is located on the vertical mid-perpendicular plane of the energy absorption box, and the length of the scissors fork does not exceed the width of the anti-collision steel plate.
[0010] Preferably, positioning sleeves are provided at the center positions of the opposing surfaces of the base and the anti-collision steel plate, and a multi-section spring telescopic rod is provided between the two positioning sleeves.
[0011] Preferably, a thicker end of the multi-section spring telescopic rod corresponds to the anti-collision steel plate, and a reinforcing angle plate is evenly fixed between the surface of one end of the multi-section spring telescopic rod close to the anti-collision steel plate and the anti-collision steel plate.
[0012] Preferably, an energy absorbing groove corresponding to the position of the multi-section spring telescopic rod is provided on a side of the base away from the multi-section spring telescopic rod.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] (1) The utility model arranges an anti-collision steel plate, a scissors fork and a multi-section spring telescopic rod inside the energy absorbing box. The scissors fork is symmetrically arranged in the upper and lower parts and in the left and right parts inside the energy absorbing box, and the multi-section spring telescopic rod is on the horizontal axis of the energy absorbing box, so that the scissors fork and the multi-section spring telescopic rod can guide the anti-collision steel plate and the energy absorbing box to be depressed by the collision. No matter which side of the rear of the energy absorbing box the collision occurs, the anti-collision steel plate will be sunken and contracted at the same time under the action of the scissors fork and the multi-section spring telescopic rod, so as to prevent the vehicle from turning and causing a secondary collision due to uneven force and different depression on both sides, thereby improving the safety of the collision vehicle and solving the problem that the anti-collision buffer pad currently circulating on the market does not have a guiding and limiting measure, which easily causes the collision vehicle to turn due to resistance, resulting in a secondary collision and further causing damage.
[0015] (2) The utility model uses scissors and multi-section spring telescopic rods to make the energy absorption box shrink on both sides at the same time when it is hit, so that the buffering effect of all the energy absorption honeycomb core panels on the left and right parts of the energy absorption box can be fully utilized, thereby improving the energy absorption and anti-collision effect and improving the safety of use.
[0016] (3) The utility model provides an energy-absorbing groove corresponding to the position of the multi-section spring telescopic rod on the side of the base away from the multi-section spring telescopic rod. When the anti-collision steel plate and the energy-absorbing box are hit, the multi-section spring telescopic rod will first shrink to absorb energy. When the collision is serious and the degree of depression is large, the pressure on the multi-section spring telescopic rod is also relatively large. The energy-absorbing groove reduces the thickness of the corresponding position of the base, which helps the position to break first to make way for the multi-section spring telescopic rod, thereby ensuring that the energy-absorbing box has sufficient buffer distance and depression space, thereby ensuring the safety of the rear vehicle.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1-5 As shown, the utility model provides a technical solution: an anti-deflection vehicle-mounted anti-collision buffer pad, comprising a base 1 connected to a vehicle body, an energy absorption box 2 fixed to a side of the base 1 away from the vehicle body, and a top plate 3 arranged on a side of the energy absorption box 2 away from the base 1, a load-bearing beam hinge seat 101 and a flip push rod hinge seat 102 for connecting to a vehicle body load-bearing beam and a flip push rod are fixedly connected above and below the base 1, respectively, a vehicle taillight 9 is arranged on both sides of the top plate 3, two groups of support rods 4 are arranged between the base 1 and the top plate 3, and the two groups of support rods 4 are respectively installed on the upper surface and the lower surface of the energy absorption box 2;
[0025] An anti-collision steel plate 5 parallel to the base 1 is vertically arranged inside the energy absorption box 2, and both sides of the top and bottom of the anti-collision steel plate 5 opposite to the base 1 are horizontally fixedly connected with slide seats 6, and scissors 7 are horizontally arranged at positions near the top and bottom of the inner wall of the energy absorption box 2. The eight ends of the scissors 7 are slidably connected to the slide seats 6 at corresponding positions, and the width of the anti-collision steel plate 5 is adapted to the width of the energy absorption box 2. The central rotation axis of the scissors 7 is located on the vertical mid-vertical plane of the energy absorption box 2, and the length of the scissors 7 does not exceed the width of the anti-collision steel plate 5;
[0026] The interior of the energy absorption box 2 is filled with energy absorbing honeycomb core panels 8 on the side of the anti-collision steel plate 5 close to the vehicle body and the side away from the vehicle body. Positioning sleeves 10 are provided at the center position of the opposite surfaces of the base 1 and the anti-collision steel plate 5. A multi-section spring telescopic rod 11 is provided between the two positioning sleeves 10. The thicker end of the multi-section spring telescopic rod 11 corresponds to the anti-collision steel plate 5. Reinforcing angle plates 12 are evenly fixed between the surface of one end of the multi-section spring telescopic rod 11 close to the anti-collision steel plate 5 and the anti-collision steel plate 5. An energy absorption groove 103 corresponding to the position of the multi-section spring telescopic rod 11 is provided on the side of the base 1 away from the multi-section spring telescopic rod 11.
[0027] Working principle: The scissors fork is symmetrically arranged in the upper and lower parts and the left and right parts inside the energy absorption box, and the multi-section spring telescopic rod is on the horizontal axis of the energy absorption box, so that the scissors fork and the multi-section spring telescopic rod can guide the anti-collision steel plate and the energy absorption box to be dented by collision. No matter which side of the rear of the energy absorption box is hit, the anti-collision steel plate will be dented and contracted on both sides at the same time under the action of the scissors fork and the multi-section spring telescopic rod, so as to prevent the vehicle from turning and causing a secondary collision due to uneven force and different depression on both sides, thereby improving the safety of the collision vehicle. The scissors fork and the multi-section spring telescopic rod can make the energy absorption box be dented on both sides by collision. At the same time, it sinks and shrinks, so it can make full use of the buffering effect of all the energy-absorbing honeycomb core panels on the left and right parts of the energy-absorbing box, improve the energy absorption and anti-collision effect, and improve the safety of use. When the anti-collision steel plate and the energy-absorbing box are collided, the multi-section spring telescopic rod will shrink first to absorb energy. When the collision is serious and the degree of depression is large, the pressure on the multi-section spring telescopic rod is also relatively large. The energy-absorbing groove reduces the thickness of the corresponding position of the base, which helps this position to break first to make way for the multi-section spring telescopic rod, ensuring sufficient buffering distance and depression space for the energy absorption box, and ensuring the safety of the rear vehicle.
