Description

Technical Field

[0001] The present invention relates to the technical field of automotive anti-collision, and particularly to an anti-collision structure for vehicles used in traffic. Background Art

[0002] During the use of a vehicle, an anti-collision beam is usually provided at the front end of the vehicle to protect the vehicle against collisions. Such anti-collision beams are usually designed as solid cast iron, which can buffer the impact force of the impact, thereby protecting the vehicle body itself from deformation. However, traditional vehicle anti-collision beams usually have the following problems:

[0003] First, the impact source hitting the anti-collision beam needs to be buffered in a timely manner. Traditional anti-collision beams are of solid cast iron structure, but the thickness of existing anti-collision beams often fails to meet the corresponding standards, and it is extremely easy to deform. The impact force is usually large and is an instantaneous impact force. After the impact force is blocked, there will still be part of the impact force continuing to squeeze. Therefore, it is necessary to unload this part of the remaining impact force in a timely manner.

[0004] Secondly, conventional anti-collision beams are of rigid structure. However, when subjected to external impact, they will deform, but the impact source still stays on the anti-collision beam and still presses and squeezes the anti-collision beam. Therefore, the impact source needs to be pushed away from the anti-collision beam in a timely manner to avoid secondary damage to the anti-collision beam by the impact source.

[0005] Therefore, we have designed an anti-collision structure for vehicles used in traffic. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that after the impact force is blocked, there will still be part of the impact force continuing to squeeze, and to propose an anti-collision structure for vehicles used in traffic.

[0007] To achieve the above purpose, the present invention adopts the following technical scheme:

[0008] An anti-collision structure for vehicles used in traffic, including an anti-collision beam body. A pushing frame is further provided on one side of the anti-collision beam body. The pushing frame slides on the anti-collision beam body through a magnetic adsorption mechanism. A cavity is provided inside the anti-collision beam body, and a protection mechanism for resisting the impact force outside the anti-collision beam body is provided in the cavity. A protruding impact block slides on the pushing frame. A driving motor is provided at the bottom of the pushing frame, and the driving motor drives the protruding impact block to impact the inner side of the anti-collision beam body through a driving part. A limiting mechanism for positioning the impact position of the protruding impact block is provided between the cavity and the pushing frame.

[0009] Preferably, the magnetic adsorption mechanism includes:

[0010] Two side plates and two fixing rods. The two side plates are symmetrically fixed on the side walls of the pushing frame, and the two fixing rods are symmetrically fixed on the side walls of the anti-collision beam body. The fixing rods slide on the side plates through the insertion holes on the side plates;

[0011] Two first electromagnetic generators. The two first electromagnetic generators are fixed at both ends of the anti-collision beam body, and the side plates are made of ferromagnetic iron.

[0012] Preferably, the protection mechanism includes:

[0013] Multiple isolation plates. The multiple isolation plates are used to divide the cavity into multiple buffer chambers. Multiple partition plates are arranged in the buffer chambers, and a film is attached to the side of the partition plate facing the protruding impact block.

[0014] Preferably, the driving part includes:

[0015] A side sliding hole and a sliding plate. The side sliding hole is opened on the side wall of the pushing frame. The sliding plate slides through the side sliding hole, and one end of the sliding plate extending into the pushing frame through the side sliding hole is fixedly connected to the protruding impact block;

[0016] The other end of the sliding plate is fixedly provided with an end plate. A threaded hole is opened on the end plate, and the output end of the driving motor is fixedly provided with a rotating lead screw. The rotating lead screw drives the sliding plate to move through the threaded hole.

[0017] Preferably, the limiting mechanism includes:

[0018] Multiple top frames and multiple vertical frames. Flow cavities are provided on both the top frames and the vertical frames. Multiple top sliding holes corresponding to the number of vertical frames are arranged on the pushing frame. The vertical frames slide on the pushing frame through the top sliding holes;

[0019] Multiple lifting grooves are opened on the pushing frame. The lifting grooves correspond to the top sliding holes one by one. The flow cavity of the vertical frame is communicated with the lifting groove through a rubber hose, and a pressing block for blocking and limiting the protruding impact block is lifted in the lifting groove.

[0020] Preferably, multiple top frames are linearly fixed on the top of the anti-collision beam body. The flow cavity is communicated with the buffer cavity through a communication hole, and the communication hole is located between two adjacent partition plates.

[0021] Preferably, the driving motor slides on the bottom of the pushing frame through a bottom groove and a sliding frame, and the bottom groove is perpendicular to the sliding plate.

[0022] Preferably, second electromagnetic generators are provided at both ends of the sliding frame, and magnet plates are fixed at both ends of the bottom of the pushing frame.

[0023] Preferably, the thread groove on the rotating lead screw is a single-turn thread groove.

[0024] Preferably, the cavity is filled with non-Newtonian fluid.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, the pushing frame moves towards the anti-collision beam body. The external impact force impacts on one side of the anti-collision beam body, while the protruding impact block impacts on the other side of the anti-collision beam body, playing a counteracting role and at the same time being able to buffer part of the external impact force. Therefore, the pushing frame with the protruding impact block will complete a protective impact on the anti-collision beam body.

[0027] 2. In the present invention, the impact point of the protruding impact block on the anti-collision beam body is arranged in a dislocation with the impact point of the external impact force on the anti-collision beam body. Therefore, when the protruding impact block impacts on the other side of the anti-collision beam body, since the side of the protruding impact block facing the anti-collision beam body is arc-shaped, it will push the external impact force to shift, that is, unload the external impact force and push this part of the external impact force away from the anti-collision beam body.

[0037] Embodiment 1

[0038] Referring to Figures 1-8 , a traffic vehicle anti-collision structure includes an anti-collision beam body 1. A pushing frame 2 is further provided on one side of the anti-collision beam body 1. A cavity is provided inside the anti-collision beam body 1, and a protection mechanism for resisting the impact force outside the anti-collision beam body 1 is provided in the cavity. This protection mechanism is used to offset the impact force impacting on the anti-collision beam body 1 and protect the vehicle body. The setting of the protection mechanism can play a buffering role.

[0039] The pushing frame 2 slides on the anti-collision beam body 1 through a magnetic adsorption mechanism. The protruding impact block 11 is arranged on the pushing frame 2. Therefore, when an impact occurs, the first sensor transmits the electrical signal generated by the impact to the magnetic adsorption mechanism and drives the magnetic adsorption mechanism to be turned on. The first sensor is a prior art and will not be elaborated here in detail. It drives the pushing frame 2 to move towards the anti-collision beam body 1. Therefore, a primary protective impact of the pushing frame 2 with the protruding impact block 11 on the anti-collision beam body 1 will be completed.

[0040] The protruding impact block 11 slides on the pushing frame 2. The setting of the protruding impact block 11 is used to impact the other side of the anti-collision beam body 1, that is, the external impact force and the impact force of the protruding impact block 11 are respectively on both sides of the anti-collision beam body 1, and a secondary protective impact on the anti-collision beam body 1 will be completed.

[0041] A driving motor 14 is arranged at the bottom of the pushing frame 2, and the driving motor 14 drives the protruding impact block 11 to impact the inner side of the anti-collision beam body 1 through a driving part.

[0042] Therefore, the protruding impact block 11 has two functions:

[0043] Firstly: The external impact force impacts on one side of the anti-collision beam body 1, while the protruding impact block 11 impacts on the other side of the anti-collision beam body 1, playing a counteracting role and being able to play a partial buffering role for the external impact force;

[0044] Secondly: The impact point of the protruding impact block 11 on the anti-collision beam body 1 is arranged in a staggered manner with the impact point of the external impact force on the anti-collision beam body 1. Referring to Figure 8In this state, when the protruding impact block 11 impacts on the other side of the anti-collision beam body 1, since the side of the protruding impact block 11 facing the anti-collision beam body 1 is arc-shaped, it will push the external impact force to deviate, that is, relieve the external impact force, and push this part of the external impact force away from the anti-collision beam body 1.

[0045] A limiting mechanism for positioning the impact position of the protruding impact block 11 is arranged between the cavity and the pushing frame 2. This limiting mechanism is used to position the moving protruding impact block 11 and prevent the continuous sliding of the protruding impact block 11.

[0046] It should be noted that second sensors are distributed on the inner side of the anti-collision beam body 1. These second sensors are used to sense the position where the impact occurs on the anti-collision beam body 1. The second sensors are prior art and will not be elaborated here. When the impact occurs on the left side of the anti-collision beam body 1, it will drive the drive motor 14 to move to the corresponding side. Due to the existence of the limiting mechanism, it will block the continuous sliding of the protruding impact block 11 and complete the positioning of the protruding impact block 11. At this time, the protruding impact block 11 and the impact point are in an offset state, making the impact part of the protruding impact block 11 on the anti-collision beam body 1 closer to the center position of the anti-collision beam body 1 compared to the impact part of the external impact force on the anti-collision beam body 1. In this way, during the impact process of the protruding impact block 11, not only the external impact force is counter-impacted and buffered, but also due to the offset setting, the external impact is pushed towards the end during the impact process, thereby completing the unloading operation.

[0047] The working principle of the present invention is as follows:

[0048] First, under the impact of external force, the impact force will first impact on the outer side of the anti-collision beam body 1. The first sensor attached to the anti-collision beam body 1 senses the impact force and transmits this part of the electrical signal to the magnetic adsorption mechanism, and activates the magnetic adsorption mechanism, driving the pushing frame 2 to move towards the anti-collision beam body 1. Therefore, the pushing frame 2 will complete an impact on the anti-collision beam body 1 with the protruding impact block 11.

[0049] Then, the protruding impact block 11 slides on the pushing frame 2. The second sensor senses the deformation on the inner side of the anti-collision beam body 1, so it will transmit the electrical signal to the drive motor 14, and drive the protruding impact block 11 to impact the inner side of the anti-collision beam body 1 through the driving part, playing a counteracting role and being able to buffer part of the external impact force; at the same time, due to the offset state of the protruding impact block 11 and the impact point, the external impact is pushed towards the end during the impact process, thereby completing the unloading operation.

[0050] Embodiment Two

[0051] The magnetic adsorption mechanism includes two side plates 8 and two fixing rods 9. The two side plates 8 are symmetrically fixed on the side wall of the pushing frame 2, and the two fixing rods 9 are symmetrically fixed on the side wall of the anti-collision beam body 1. The fixing rods 9 slide on the side plates 8 through the jacks on the side plates 8. Therefore, the pushing frame 2 stably slides on the fixing rods 9 through the side plates 8.

[0052] The magnetic adsorption mechanism further includes two first electromagnetic generators 10. The two first electromagnetic generators 10 are fixed at both ends of the anti-collision beam body 1. When the first sensor on the anti-collision beam body 1 is impacted, the electrical signal generated by the impact is transmitted to the first electromagnetic generators 10, and the first electromagnetic generators 10 are turned on to generate a magnetic field. Since the material of the side plate 8 is metallic iron, the first electromagnetic generators 10 can adsorb the side plate 8, and finally drive the protruding impact block 11 on the pushing frame 2 to impact the inner side of the anti-collision beam body 1, completing a protective impact on the anti-collision beam body 1.

[0053] Embodiment 3

[0054] Refer to Figure 6 and Figure 7 In the state, the protection mechanism includes a plurality of isolation plates. The plurality of isolation plates are used to divide the cavity into a plurality of buffer cavities, and the buffer cavities are not connected to each other. A plurality of partition plates 20 are arranged in the buffer cavities, and a film 21 is attached to the side of the partition plate 20 facing the protruding impact block 11. Therefore, the setting of the film 21 can provide damage protection for the partition plate 20 from one side.

[0055] It should be noted that: the impact force impacts from the direction where the film 21 is not attached to the partition plate 20. The partition plate 20 is broken due to the impact force, that is, the partition plate 20 originally expands and breaks in the direction of the film 21. Due to the existence of the film 21, this tendency of expanding and breaking in the direction of the film 21 will be hindered. However, the damage of the partition plate 20 caused by the impact still exists and will produce deformation;

[0056] On the contrary, when impacted from the side of the film 21, the partition plate 20 expands and breaks in the direction opposite to the film 21 and is not hindered. Therefore, the damage of the partition plate 20 will not be hindered by the film 21, and thus it is easier to deform. From this, it can be obtained that it is not easy to deform when impacting from the outside to the inside of the anti-collision beam body 1, and it is easier to deform when impacting from the inside to the outside of the anti-collision beam body 1.

[0057] Since the cavity is filled with non-Newtonian fluid, when the outside of the anti-collision beam body 1 is impacted, the cavity with non-Newtonian fluid will be impacted. Under the impact, the cavity deforms, and the existence of non-Newtonian fluid will resist the impact force of this sudden impact, playing a protective role. Then, under the continuous action of the external force, the impact force at this time is not a sudden impact but becomes a slow extrusion state. This slow extrusion state will continuously extrude the non-Newtonian fluid in the cavity, squeeze and stack the multiple partition plates 20, and extrude most of the non-Newtonian fluid out of the cavity, thus completing the secondary protection function.

[0058] Embodiment Four

[0059] The driving part includes a side sliding hole 6 and a sliding plate 12. The side sliding hole 6 is opened on the side wall of the pushing frame 2. The sliding plate 12 slides through the side sliding hole 6, and one end of the sliding plate 12 extending into the pushing frame 2 through the side sliding hole 6 is fixedly connected to the protruding impact block 11. Therefore, when the sliding plate 12 slides in the side sliding hole 6, an end plate 13 is fixed to the other end of the sliding plate 12. A threaded hole is opened on the end plate 13. The output end of the driving motor 14 is fixedly connected to a rotating lead screw 15. The rotating lead screw 15 drives the sliding plate 12 to move through the threaded hole. Therefore, when the driving motor 14 is turned on, the rotating lead screw 15 rotates, and the sliding plate 12 is driven by the end plate 13 to impact in the direction of the anti-collision beam body 1 on the side sliding hole 6. The thread groove on the rotating lead screw 15 is a single-turn thread groove. Therefore, when the rotating lead screw 15 rotates one circle, it can quickly drive the end plate 13 to move on the rotating lead screw 15, and thus can provide a faster impact speed for the protruding impact block 11 for the primary protective impact on the anti-collision beam body 1.

[0060] Both ends of the sliding frame 17 are provided with second electromagnetic generators 18. Both ends of the bottom of the pushing frame 2 are fixedly connected with magnet plates 7. It should be noted that when the protruding impact block 11 impacts the outside of the anti-collision beam body 1 and causes the anti-collision beam body 1 to deform, a second sensor is internally attached to the inner side of the anti-collision beam body 1. This second sensor senses the deformation on the inner side of the anti-collision beam body 1, so it will transmit an electrical signal to the second electromagnetic generator 18 and turn on the second electromagnetic generator 18 to generate a magnetic field for adsorbing the magnet plates 7 at both ends of the bottom of the pushing frame 2;

[0061] Among them, the second sensor is used to sense the position of the impact on the anti-collision beam body 1. The second sensor is a prior art and will not be elaborated here. The driving motor 14 slides on the bottom of the pushing frame 2 through the bottom groove 16 and the sliding frame 17. The bottom groove 16 is perpendicular to the sliding plate 12. When impacting the left side of the anti-collision beam body 1, it will drive the second electromagnetic generator 18 on one side to adsorb the magnet plate 7 on the corresponding side, and the driving motor 14 will move to the corresponding side.

[0062] Embodiment Five

[0063] Reference Figure 4 and Figure 5 In the state, the limiting mechanism includes a plurality of top frames 3 and a plurality of vertical frames 4. Flow cavities 22 are provided on both the top frames 3 and the vertical frames 4. A plurality of top sliding holes 5 corresponding to the number of the vertical frames 4 are provided on the pushing frame 2. The vertical frames 4 slide on the pushing frame 2 through the top sliding holes 5 to provide support for the sliding of the pushing frame 2.

[0064] The limiting mechanism further includes a plurality of lifting grooves. The lifting grooves are opened on the pushing frame 2 and correspond to the top sliding holes 5 one by one. The flow cavity 22 of the vertical frame 4 is communicated with the lifting grooves through rubber hoses. A pressing block 19 for blocking and limiting the protruding impact block 11 is lifted in the lifting grooves. A plurality of top frames 3 are linearly fixed on the top of the anti-collision beam body 1. The flow cavity 22 is communicated with the buffer cavity through a communication hole 23. The communication hole 23 is located between two adjacent partition plates 20. It should be noted that a plurality of lifting grooves are linearly opened in the side sliding holes 6. Therefore, when the anti-collision beam body 1 is impacted, the non-Newtonian liquid in the cavity is squeezed, and is squeezed into the flow cavity 22 through the communication hole 23, and then flows into the lifting grooves through the rubber hoses, and finally the pressing block 19 in the lifting grooves is extruded out of the lifting grooves, thereby completing the interception of the sliding plate 12.

[0065] Therefore, the pressing block 19 extending out of the lifting groove will block the continuous sliding of the protruding impact block 11 to complete the positioning of the protruding impact block 11. At this time, the protruding impact block 11 and the impact point are in an offset state, so that the impact part of the protruding impact block 11 on the anti-collision beam body 1 is closer to the center position of the anti-collision beam body 1 than the external impact force impacts on the anti-collision beam body 1. In this way, during the impact process of the protruding impact block 11, not only the external impact force is counter-impacted and buffered, but also due to the offset setting, the external impact is pushed towards the end during the impact process, thereby completing the unloading operation.

[0066] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
