Abstract
Description
Technical Field
[0001] The invention relates to the field of automobiles, and in particular to a collision energy absorption technology for automobiles. Background Art
[0002] Vehicles have been commercialized for over a hundred years. The safety of vehicles is mainly reflected in their ability to absorb impact energy when a collision occurs. It is well known that the stronger the energy absorption, the safer the people on the vehicle. The current design of vehicles fixes the various accessories on the body and frame into one. When a collision occurs, the energy of the impact will adhere to the fixedly connected body and frame and transfer the energy to the entire vehicle. Although there are front and rear "crush zones" on the body, and "energy absorption boxes" are installed in certain positions, the materials used in the crush zones are easier to deform and damage, but the materials are made of metal after all, and they have a certain rigidity and strength. The area and depth that rely on deformation and damage to absorb the impact energy are also limited, so within the range of energy absorption, the force is not enough. However, due to its small size, the energy absorption box has limited deformation and depth, and the energy it can effectively absorb is also limited. The remaining energy will be transmitted by the fixedly connected vehicle body, and the vehicle body will be further damaged and deformed to continue to absorb the remaining energy until the energy is completely absorbed. This traditional energy absorption method of "hard-on-hard" rigid direct contact will often cause damage to both people and vehicles, posing a great threat to the safety of people on the vehicle. Therefore, although the existing energy absorption collapse device can reduce the impact force, because it is a "hard-on-hard" rigid direct contact, the tangible price it pays is the damage to the vehicle, and the intangible price is that the safety of people on the vehicle is seriously threatened. Summary of the invention
[0003] The purpose of the present invention is to provide a vehicle bridge breaking energy absorption device, so as to further improve the anti-collision protection effect of the vehicle.
[0004] The present invention is implemented as follows: the vehicle bridge-breaking energy absorption device includes a bumper bar arranged at the end of the frame, the bumper bar is slidably connected to the frame and can slide forward and backward, in particular, the frame is connected to a hollow tube, a plurality of inflated balls are placed in the hollow tube, a compression spring is provided between the bumper bar and the hollow tube, one end of the compression spring is connected to the bumper bar, and the other end presses on the ball, and all the balls in the hollow tube bear the impact force transmitted by the compression spring to the bumper bar together.
[0005] As a best embodiment, wood is padded between the compression spring and the safety rod, and wood is padded between the compression spring and the ball.
[0006] As a best embodiment, the outer side of the bumper is covered with wood.
[0007] The advantages of the present invention are: on the one hand, the bumper at the end of the frame (including the front and / or the rear) is not fixedly connected to the vehicle body, and the bumper is slidably connected to the frame and can move freely forward and backward, forming an independent "broken bridge" device. The energy during the collision is absorbed by the independent broken bridge device, so that the impact energy can no longer be transmitted to the entire vehicle by adhering to the vehicle body frame. The bumper that can move freely forward and backward cuts off the path of the impact energy being transmitted along the vehicle body, and transmits the energy to the spring and the ball to absorb and buffer in a flexible manner, further reducing the degree of damage to the vehicle and improving the safety of the people on the vehicle. On the other hand, the present invention not only uses the spring to absorb the collision energy, but also uses the inflated ball to absorb the collision energy. Because air itself has the best flexible buffering function, each ball is filled with air, just like the falling life-saving air cushion used for high-rise life-saving. When the car collides, it is like colliding with a soft life-saving air cushion, which is a soft "softness overcomes hardness" best buffering energy absorption and shock absorption method. In addition, the spring and the inflated ball have good toughness. The two together bear the collision force to better prolong the collision contact time, and can provide a higher level of safety standards for people and cars. Furthermore, the inflated ball is only compressed air when a collision occurs, and the ball has a very low damage rate and can be reused. Even if it is damaged, it can be replaced quickly and conveniently. It only needs to be taken out of the hollow tube and replaced, and the cost of the ball is also cheap. In short, the cost of implementing the present invention is extremely low (only the ball and the spring), easy to install, and no maintenance is required, and it is good value for money. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 is a schematic structural diagram of Embodiment 1 of the present invention; Figure 2 It is a structural diagram of embodiment 2 of the present invention. DETAILED DESCRIPTION
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] The embodiment of the vehicle bridge breaking energy absorption device of the present invention is as follows: Figure 1 As shown, it includes a bumper 1 arranged at the end of the frame, and the bumper 1 is slidably connected to the frame and can slide forward and backward. A hollow tube 2 is fixed to the frame. A plurality of inflated leather balls 3 are placed in the hollow tube 2. The leather balls 3 are arranged closely to each other. A compression spring 4 is provided between the bumper 1 and the hollow tube 2. One end of the compression spring 4 is connected to the bumper 1, and the other end presses on the leather balls 3. When a collision occurs at the front end of the vehicle, the bumper 1 directly bears the collision force, and the collision force is transmitted to the leather balls 3 via the compression spring 4. All the leather balls in the hollow tube 2 bear the impact force of the bumper 1 together, providing excellent buffering and anti-collision protection for the vehicle. The hollow tube 2 can be made of materials such as steel.
[0011] Figure 1The bumper 1 shown in the figure can be the front bumper of a car or the rear bumper of a car. The front and rear bumpers of the same car can be provided with the structure described in the present embodiment.
[0012] Figure 2 is Figure 1 An embodiment further improved on the basis of. In this embodiment, wood 5 and 6 are respectively padded between the compression spring 4 and the bumper 1 and between the compression spring 4 and the ball 3. Wood itself has good elasticity and impact resistance, which can further improve the anti-collision protection effect. Furthermore, in this embodiment, the outer side of the bumper 1 is covered with wood 7, which further improves the anti-collision protection effect. The outer side of the bumper is the front side of the bumper for the front bumper of the car, and is the rear side of the bumper for the rear bumper of the car.
[0013] It should be noted that the shape of the leather ball of the present invention can be any shape such as an ellipse or even a cube, and is not limited to a sphere.
