Technical Field

The invention belongs to the technical field of automobile accessories, and particularly relates to an automobile anti-collision beam.

Background

The anti-collision beam is a device for reducing the impact energy absorbed when a vehicle is collided, and consists of a main beam, an energy absorption box and a mounting plate connected with the vehicle, wherein the main beam and the energy absorption box can effectively absorb the impact energy when the vehicle is collided at a low speed, so that the damage of the impact force to a vehicle body longitudinal beam is reduced as much as possible, and the anti-collision beam plays a role in protecting the vehicle; the anti-collision beam structure can ensure that the low-speed energy absorption box effectively absorbs energy during low-speed collision through crumpling, and the anti-collision beam is connected to a vehicle body through bolts and is convenient to detach and replace. All add on the anticollision roof beam of many motorcycle types at present and be equipped with one deck foam buffer, its main effect still plays a support to outside plastic bumper when the collision below 4km/h, alleviates the effect of collision power, reduces the collision and to the damage of plastic bumper, reduces cost of maintenance.

The anti-collision beam is used as an important safety part in an automobile and mainly has the main functions that when the automobile is collided, the anti-collision box in the anti-collision beam can deform to further absorb impact energy generated when the automobile is collided, so that the safety of drivers and passengers in the automobile is ensured, most of the energy absorption boxes of the existing anti-collision beam adopt a cylindrical structure, and the side wall of the energy absorption box is of a vertical structure, so when the automobile is impacted positively, the impact force acts on the energy absorption box along the axial direction of the energy absorption box, and because the side wall of the energy absorption box is of a vertical structure, the energy absorption box is difficult to be compressed and deformed (for example, as shown in figure 8, when the positive impact force acts on the energy absorption box, along with the increase of the force acting on the energy absorption box, because the side wall of the traditional box is of the vertical structure and the positive action force is parallel to the side wall of the energy absorption box, and then only when the force acting on the energy absorption box exceeds the limit strength which the energy absorption box can bear, the crash box can only produce bending deformation at this moment, so the deformation process of traditional crash box when receiving the front impact is the process of sudden change, when the impact force does not exceed the ultimate strength that can bear of crash box, then the crash box keeps original form), and then can't be through the impact energy who produces when deformation absorption vehicle striking, and then make impact energy transmit the automobile body, and then transmit to in the car on the driver and passenger's body, and then cause driver and passenger's damage.

Disclosure of Invention

In order to make up the defects of the prior art, the invention provides an automobile anti-collision beam. The anti-collision beam is mainly used for solving the problem that when the traditional anti-collision beam is subjected to frontal impact, the energy absorption box is not easy to deform and cannot absorb impact energy, and therefore the impact energy is transmitted to a vehicle body to cause damage to drivers and passengers.

The technical scheme adopted by the invention for solving the technical problems is as follows: an automobile anti-collision beam comprises a main beam, an energy absorption component and a frame connecting piece; energy absorption components are symmetrically arranged on one side of the main beam; one end of the energy absorption component is fixedly connected with the main beam through a bolt; the other end of the energy absorption part is provided with the frame connecting piece; the energy absorption component is connected with the frame connecting piece; the side wall of the energy absorption part is of a corrugated structure.

When the automobile is collided, the energy absorption boxes of the existing anti-collision beams are mostly in a cylindrical structure, the side walls of the energy absorption boxes are in a vertical structure, so that when the automobile is impacted in a front direction, impact force acts on the energy absorption boxes along the axial direction of the energy absorption boxes, and the side walls of the energy absorption boxes are in a vertical shape, so that the energy absorption boxes are difficult to be compressed and deformed (for example, as shown in figure 8, when the front impact force acts on the energy absorption boxes, along with the increase of the force acting on the energy absorption boxes, because the side walls of the traditional energy absorption boxes are in a vertical structure and are parallel to the side walls of the boxes, and only when the force acting on the energy absorption boxes exceeds the limit strength which the energy absorption boxes can bear, the energy-absorbing box can be bent and deformed, so that the deformation process of the traditional energy-absorbing box when the energy-absorbing box is subjected to the front impact is a sudden change process, and when the impact force does not exceed the limit strength which can be borne by the energy-absorbing box, the energy-absorbing box keeps the original shape), so that the impact energy generated when a vehicle is impacted can not be absorbed through deformation, and the impact energy is transmitted to the vehicle body and further transmitted to the body of a driver and a passenger in the vehicle, and further the damage to the driver and the passenger is caused; therefore, in this embodiment, by configuring the side wall of the energy absorbing member to have a corrugated structure, when the vehicle impact energy absorbing member is subjected to a frontal impact, the impact force parallel to the axial direction of the energy absorbing member cannot be kept parallel to the side wall of the energy absorbing member, (for example, as shown in fig. 7, when the energy absorbing member is parallel to the axial direction of the acting force N, the force applied to the side wall of the energy absorbing member on the plane not parallel to the axial line forms a certain angle with the side wall, so that the force applied to the side wall of the energy absorbing member has a component in the direction perpendicular to the side wall, so that a radial force is applied to a local side wall, and since the corrugated structure of the energy absorbing member is uniformly arranged, so that the force applied to each part of the energy absorbing member is uniform), and when the energy absorbing member is subjected to a frontal impact, the energy absorbing member can be deformed easily and uniformly (for example, as shown in fig. 8, when the energy absorbing member is subjected to a frontal impact, energy-absorbing part then can slow deformation, increase along with the effort and the increase of action time, make the deflection increase gradually, reach the biggest deflection at last), energy-absorbing part is through the energy of deformation absorption impact all the time at whole in-process until reaching the biggest deflection, and then at the whole in-process of vehicle collision, the impact force that the absorption collision produced all the time, and then guaranteed that energy-absorbing part can reliable and stable absorption impact energy, and then avoid most impact force to transmit the automobile body, and then reduced the impact that driver received, and then guaranteed driver and crew's safety, and then the safeguard function of anticollision roof beam has been improved.

When the automobile is collided, the energy absorption boxes of the existing anti-collision beams are mostly in a cylindrical structure, the side walls of the energy absorption boxes are in a vertical structure, so that when the automobile is impacted in a front direction, impact force acts on the energy absorption boxes along the axial direction of the energy absorption boxes, and the side walls of the energy absorption boxes are in a vertical shape, so that the energy absorption boxes are difficult to be compressed and deformed (for example, as shown in figure 8, when the front impact force acts on the energy absorption boxes, along with the increase of the force acting on the energy absorption boxes, because the side walls of the traditional energy absorption boxes are in a vertical structure and are parallel to the side walls of the boxes, and only when the force acting on the energy absorption boxes exceeds the limit strength which the energy absorption boxes can bear, the energy-absorbing box can be bent and deformed, so that the deformation process of the traditional energy-absorbing box when the energy-absorbing box is subjected to the front impact is a sudden change process, and when the impact force does not exceed the limit strength which can be borne by the energy-absorbing box, the energy-absorbing box keeps the original shape), so that the impact energy generated when a vehicle is impacted can not be absorbed through deformation, and the impact energy is transmitted to the vehicle body and further transmitted to the body of a driver and a passenger in the vehicle, and further the damage to the driver and the passenger is caused; therefore, in this embodiment, by configuring the side wall of the energy absorbing member 2 to have a corrugated structure, and further when the vehicle impacts the energy absorbing member 2 in a frontal direction, the impact force parallel to the axial direction of the energy absorbing member 2 cannot be kept parallel to the side wall of the energy absorbing member 2 (for example, as shown in fig. 7, when the energy absorbing member 2 is parallel to the axial direction, the force applied to the side wall of the energy absorbing member 2 on the plane not parallel to the axial direction forms a certain angle with the plane, and further the force applied to the side wall of the energy absorbing member 2 has a component in the direction perpendicular to the side wall, and further the local side wall is applied with a radial force, and simultaneously, because the corrugated structure of the energy absorbing member 2 is uniformly arranged, the force applied to each part of the energy absorbing member 2 is uniform), and further, when the energy absorbing member 2 is impacted in the frontal direction, the energy absorbing member can be deformed easily and uniformly (for example, as shown in fig. 8, when the energy-absorbing part 2 receives forward force, the energy-absorbing part 2 can slowly deform, along with the increase of acting force and the increase of acting time, the deformation is gradually increased, and finally, the maximum deformation is reached, the energy of the impact is absorbed through deformation all the time by the energy-absorbing part 2 in the whole process until the maximum deformation is reached, and then in the whole process of vehicle collision, the impact force generated by the collision is absorbed all the time, and then the energy of the impact can be stably and reliably absorbed by the energy-absorbing part 2, and further most of the impact force is prevented from being transmitted to the vehicle body, and further the impact received by a driver is reduced, and further the safety of the driver and passengers is ensured, and further the protection function of the anti-collision beam is improved.

As shown in fig. 2 to 4, buffer blocks 4 are symmetrically arranged on two sides of the energy absorbing component 2 in the horizontal direction; one side surface of the buffer block 4 is of a corrugated structure and is abutted against one side surface of the energy absorption part 2; the energy absorption part 2 is symmetrically provided with hoop parts 5 in the vertical direction; the two ends of the hoop member 5 are fixedly connected through bolts; the other side of the buffer block 4 is abutted against the inner side of the hoop member 5.

When the automobile is in operation, the side wall of the energy-absorbing component 2 is of a corrugated structure, and the energy-absorbing component 2 is connected with the main beam 1 and the frame, so that the energy-absorbing component 2 is likely to deform along with the running of the automobile in the running process of the automobile, and further the energy-absorbing component 2 which is impacted by the front cannot deform and absorb energy uniformly and reliably when the automobile is impacted, so that drivers and passengers are damaged; therefore, in the scheme, the buffer blocks 4 and the anchor ears are arranged on the two sides of the energy-absorbing component 2, so that the deformation of the energy-absorbing component 2 is limited from the outside, the deformation of the energy-absorbing component 2 in the vehicle form process is prevented, the energy-absorbing component 2 can be reliably and uniformly deformed when the vehicle is impacted, and the impact energy is absorbed through the deformation, so that the safety of drivers and passengers is protected; meanwhile, one side surface of the buffer block 4 is corrugated, so that one side surface of the buffer block 4 is completely attached to the outer contour of the energy absorption component 2, thereby increasing the contact area between the buffer block 4 and the energy-absorbing component 2 and further better supporting the energy-absorbing component 2, and simultaneously because the buffer block 4 is completely attached to the energy-absorbing component 2, when one end of the energy-absorbing component 2 is impacted, the acting force is firstly transmitted to the corrugated structure close to the stressed end of the energy-absorbing component 2, so that the buffer block 4 close to the stress end is uniformly extruded and the force is transmitted to the next layer of corrugated structure of the energy-absorbing component 2, thereby ensuring that when one end of the energy-absorbing component 2 is stressed, the acting force can act on each layer of corrugated structure of the energy-absorbing component 2 uniformly, the energy absorption part 2 can be ensured to deform uniformly and reliably, and the safety performance of the anti-collision beam is further improved; simultaneously because buffer block 4 is flexible material, and then make the anticollision roof beam can realize the deformation of side direction, and then can bear the impact force of side direction.

As shown in fig. 2 to 4, the inside of the buffer block 4 is provided with particulate matter; the particulate matter is a rigid material.

When the energy absorption component works, the side wall of the energy absorption component 2 is of a corrugated structure, and one side surface of the buffer block 4 is completely attached to the energy absorption component 2, so that when the energy absorption component 2 is impacted and deformed, the corrugated structures of all layers are close to each other in an arc manner, the buffer block 4 is further extruded, and then the local part of one side surface, close to the energy absorption component 2, of the buffer block 4 is subjected to shearing force; therefore, in the scheme, rigid granular materials (such as gravel, metal particles, hard plastic particles and the like) are added into the manufacturing materials of the buffer block 4, so that the toughness of the buffer block 4 is improved, when the energy absorption component 2 deforms and extrudes the buffer block 4, the rigid particles in the buffer block 4 are close to each other in an arc shape, so that the force can be transmitted through the rigid particles, the force applied to the buffer block 4 is uniformly dispersed to the whole buffer block 4, the buffer block 4 is prevented from forming stress concentration at the position extruded by the energy absorption component 2, and the risk of damage to the buffer block 4 is reduced; simultaneously because the power that energy-absorbing part 2 extruded buffer block 4 is dispersed on whole buffer block 4, and then makes the extrusion force that buffer block 4 can bear increase, and then makes the impact force that buffer block 4 can absorb increase, has further improved the energy-absorbing effect of anticollision roof beam, and then has improved the security performance of anticollision roof beam.

As shown in fig. 3 and 4, the energy absorbing component 2 is internally provided with support rings 6 at regular intervals; the outer side of the support ring 6 is in contact with the energy absorbing part 2; a support part 7 is arranged on the inner side of the support ring 6; the support member 7 is used for providing a supporting force for the support ring 6.

When the energy absorption component 2 is impacted and deformed during working, the energy absorption component 2 is compressed, so that the cross section of the energy absorption component 2 is increased, since the outside of the energy absorbing component 2 is provided with the buffer block 4 for supporting, if the inside is not supported, the energy absorbing component 2 can be deformed inwards completely, thereby causing the deformation of the energy absorbing member 2 to be non-uniform and further causing the deformation to be irregular, further, the deformation cannot be uniformly and reliably carried out all the way through the whole process of the impact, further the impact energy cannot be absorbed in the whole impact process, thereby causing impact energy to be transmitted to the vehicle body during the collision process and further causing damage to drivers and passengers, but if the shaping support consistent with the external support is adopted, the support structure can completely limit the deformation of the energy-absorbing component 2, thereby causing the energy-absorbing effect of the energy-absorbing component 2; therefore, in the scheme, the support ring 6 and the support part 7 are arranged in the energy-absorbing part 2, the support ring 6 is distributed intermittently, so that local support is formed in the energy-absorbing part 2, further, the energy-absorbing part 2 is prevented from completely contracting towards the inside in the deformation process, further, the energy-absorbing part 2 is prevented from being irregularly deformed, further, the energy-absorbing part 2 can be uniformly and reliably deformed in the whole vehicle impact process, further, the energy-absorbing part 2 can absorb impact energy generated by impact in the whole impact process, further, the energy is prevented from being transmitted to a vehicle body in the impact process, and further, the safety of drivers and passengers is ensured; meanwhile, the support rings 6 are distributed intermittently, so that the problem that the energy absorption component 2 is difficult to deform is avoided, and the energy absorption effect of the energy absorption component 2 is ensured.

As shown in fig. 3 and 4, the support part 7 includes a movable head 71, a support bracket 72 and a screw 73; the screw 73 is arranged at one end of the energy-absorbing component 2 close to the frame connecting piece 3; the screw 73 is rotationally connected with an end plate on the energy-absorbing part 2; the screw rods 73 are uniformly provided with movable heads 71 at intervals; the movable head 71 is in threaded connection with the screw 73; supporting frames 72 are arranged on one side of the movable head 71 at uniform intervals; one end of the supporting frame 72 is hinged with the movable head 71; the other end of the supporting frame 72 is abutted against the inner side of the supporting ring 6; the screw 73 is made of a flexible material.

When the energy absorption component 2 works, when an internal support is installed, the support and the movable head 71 are firstly placed in the energy absorption component 2, one end of the support rod is contacted with the support ring 6, then the screw 73 is rotated, the movable head 71 on the screw 73 is further moved, along with the movement of the movable head 71, one end of the support frame 72 is contacted with the support ring 6, and further the support frame 72 deflects, because one end of the support ring 6 is rotatably connected with the movable head 71, and further along with the rotation of the support frame 72, two ends, close to the support frame 72, of the support frame 72 move towards one end of the support ring 6, so that the support frame 72 is propped against the support ring 6, further the energy absorption component 2 is locally supported from the inside, further the energy absorption component 2 is prevented from completely contracting towards the inside in the deformation process, further the energy absorption component 2 is prevented from irregularly deforming, and further the energy absorption component 2 can uniformly and reliably deform in the whole vehicle impact process, so that the energy absorption part 2 can absorb impact energy generated by the impact in the whole impact process, thereby preventing the energy from being transmitted to the vehicle body in the impact process and further ensuring the safety of drivers and passengers; when the internal support is used for installation, an operator can realize the internal support mainly by rotating the screw 73, so that the support part 7 is convenient to install, and the anti-collision beam is convenient to install and maintain; meanwhile, the arranged screw rods 73 are made of flexible materials, and the movable heads 71 and the support rods are distributed at intervals in the axial direction, so that the lateral deformation of the energy absorption part 2 is not affected, the lateral deformation of the anti-collision beam can be realized, and the lateral impact force can be borne.

As shown in fig. 1 to 5, springs 8 are symmetrically arranged at one end of the energy absorbing component 2 close to the frame connecting piece 3; one end of the spring 8 is connected with the energy absorption part 2; the other end of the spring 8 is connected with the frame connecting piece 3.

When the automobile is in operation, the energy absorbing component 2 is easy to deform when being subjected to frontal impact, and further can deform when being subjected to slight impact, and further the maintenance cost of the automobile can be increased, therefore, the spring 8 is arranged between the energy absorbing component 2 and the frame connecting piece 3, when the automobile is subjected to slight impact, the spring 8 absorbs the energy of the impact through the deformation of the spring 8, and further the energy of the impact is prevented from being transmitted to the automobile body, and meanwhile, the deformation of the energy absorbing component 2 is also prevented, so that the damage of the energy absorbing component 2 is prevented when the automobile is slightly impacted, and further the maintenance cost of the automobile under slight impact is reduced.

As shown in fig. 3 to 5, a connecting rod 9 is symmetrically arranged on one side of the frame connecting piece 3; two ends of the connecting rod 9 are respectively provided with a ball head 10; the connecting rod 9 is arranged in two sections; the middle parts of the connecting rods 9 are connected through threads; the spring 8 is sleeved on the connecting rod 9; waist-shaped holes 11 are symmetrically formed in the end plate on one side of the energy absorption part 2 and the frame connecting piece 3; the spherical surfaces at the two ends of the connecting rod 9 are respectively contacted with one side surface of the upper end plate of the energy absorption part 2 and one side surface of the frame connecting piece 3.

When the anti-collision beam works, most of the anti-collision beams are connected with the vehicle body through bolts, and further when the vehicle is impacted laterally, the bolts for connection are subjected to lateral force, so that the bolts are generally called to deform or tear, and the energy-absorbing component 2 and the vehicle body are difficult to detach during maintenance; consequently set up bulb 10 through the both ends at the connecting piece in this scheme, and the connecting piece is installed in waist shape hole 11, and then when the anticollision roof beam received the impact of side direction, connecting rod 9 can take place to deflect, and then make connecting rod 9 can not cause deformation or tear because of receiving the yawing force, and then prevent the risk that the anticollision roof beam is difficult to demolish after the striking, simultaneously because the bulb 10 that sets up, when connecting rod 9 deflects, still can keep the in close contact with energy-absorbing part 2 and frame connection 3, and then guarantee the reliability of connecting.

When the automobile is collided, the energy absorption boxes of the existing anti-collision beams are mostly in a cylindrical structure, the side walls of the energy absorption boxes are in a vertical structure, so that when the automobile is impacted in a front direction, impact force acts on the energy absorption boxes along the axial direction of the energy absorption boxes, and the side walls of the energy absorption boxes are in a vertical shape, so that the energy absorption boxes are difficult to be compressed and deformed (for example, as shown in figure 8, when the front impact force acts on the energy absorption boxes, along with the increase of the force acting on the energy absorption boxes, because the side walls of the traditional energy absorption boxes are in a vertical structure and are parallel to the side walls of the boxes, and only when the force acting on the energy absorption boxes exceeds the limit strength which the energy absorption boxes can bear, the energy-absorbing box can be bent and deformed, so that the deformation process of the traditional energy-absorbing box when the energy-absorbing box is subjected to the front impact is a sudden change process, and when the impact force does not exceed the limit strength which can be borne by the energy-absorbing box, the energy-absorbing box keeps the original shape), so that the impact energy generated when a vehicle is impacted can not be absorbed through deformation, and the impact energy is transmitted to the vehicle body and further transmitted to the body of a driver and a passenger in the vehicle, and further the damage to the driver and the passenger is caused; therefore, in this embodiment, by configuring the side wall of the energy absorbing member 2 to have a corrugated structure, and further when the vehicle impacts the energy absorbing member 2 in a frontal direction, the impact force parallel to the axial direction of the energy absorbing member 2 cannot be kept parallel to the side wall of the energy absorbing member 2 (for example, as shown in fig. 7, when the energy absorbing member 2 is parallel to the axial direction, the force applied to the side wall of the energy absorbing member 2 on the plane not parallel to the axial direction forms a certain angle with the plane, and further the force applied to the side wall of the energy absorbing member 2 has a component in the direction perpendicular to the side wall, and further the local side wall is applied with a radial force, and simultaneously, because the corrugated structure of the energy absorbing member 2 is uniformly arranged, the force applied to each part of the energy absorbing member 2 is uniform), and further, when the energy absorbing member 2 is impacted in the frontal direction, the energy absorbing member can be deformed easily and uniformly (for example, as shown in fig. 8, when the energy-absorbing component 2 is subjected to a forward force, the energy-absorbing component 2 can slowly deform, the deformation is gradually increased along with the increase of the acting force and the increase of the acting time, and finally the maximum deformation is reached), the energy-absorbing component 2 absorbs the impact energy through deformation in the whole process until the maximum deformation is reached, so that the impact force generated by collision is absorbed all the time in the whole process of vehicle collision, the energy-absorbing component 2 can stably and reliably absorb the impact energy, most of the impact force is prevented from being transmitted to a vehicle body, the impact on drivers is reduced, the safety of the drivers and passengers is ensured, and the protection function of the anti-collision beam is improved; because the side wall of the energy-absorbing component 2 is of a corrugated structure, and the energy-absorbing component 2 is connected with the main beam 1 and the frame, the energy-absorbing component 2 can deform along with the running of the vehicle in the running process of the vehicle, so that the energy-absorbing component 2 impacted by the front cannot deform and absorb energy uniformly and reliably when the vehicle is impacted, and drivers and passengers are damaged; therefore, in the scheme, the buffer blocks 4 and the anchor ears are arranged on the two sides of the energy-absorbing component 2, so that the deformation of the energy-absorbing component 2 is limited from the outside, the deformation of the energy-absorbing component 2 in the vehicle form process is prevented, the energy-absorbing component 2 can be reliably and uniformly deformed when the vehicle is impacted, and the impact energy is absorbed through the deformation, so that the safety of drivers and passengers is protected; meanwhile, one side surface of the buffer block 4 is corrugated, so that one side surface of the buffer block 4 is completely attached to the outer contour of the energy absorption component 2, thereby increasing the contact area between the buffer block 4 and the energy-absorbing component 2 and further better supporting the energy-absorbing component 2, and simultaneously because the buffer block 4 is completely attached to the energy-absorbing component 2, when one end of the energy-absorbing component 2 is impacted, the acting force is firstly transmitted to the corrugated structure close to the stressed end of the energy-absorbing component 2, so that the buffer block 4 close to the stress end is uniformly extruded and the force is transmitted to the next layer of corrugated structure of the energy-absorbing component 2, thereby ensuring that when one end of the energy-absorbing component 2 is stressed, the acting force can act on each layer of corrugated structure of the energy-absorbing component 2 uniformly, the energy absorption part 2 can be ensured to deform uniformly and reliably, and the safety performance of the anti-collision beam is further improved; simultaneously because buffer block 4 is flexible material, and then make the anticollision roof beam can realize the deformation of side direction, and then can bear the impact force of side direction.
