Description

Technical Field

[0001] The present application relates to the technical field of new energy vehicles, and relates to a collision buffer for a collision buffer vehicle. Background Art

[0002] Policies in many places clearly stipulate that anti-collision vehicles or corresponding safety facilities with buffering and warning effects must be equipped in road construction sections. With the continuous improvement of traffic safety regulations, the requirements for safety protection in scenarios such as road construction are also increasing, which makes the importance of anti-collision vehicles more prominent and further increases the market demand for them.

[0003] As a new category, more and more anti-collision buffer vehicles are driven by new energy. Since anti-collision buffer vehicles need to be placed in road construction sections, the traffic risks they pose are higher than those of normal vehicles. Therefore, higher protection requirements are put forward for the batteries of anti-collision buffer vehicles.

[0004] The main function of the anti-collision buffer is to absorb and disperse collision energy, protect the safety of construction workers, equipment and vehicle occupants, and reduce accident risks. Specifically, through its special structural and material design, the anti-collision buffer can absorb the impact energy during a collision, reduce the impact force, and thus reduce the degree of damage to personnel and equipment.

[0005] Existing anti-collision buffers are basically disposable. After being impacted, they will undergo energy absorption deformation, and the deformation is basically plastic deformation and cannot be restored. After the anti-collision buffer is used up, a new one needs to be replaced, and it cannot be reused. Summary of the Invention

[0017] In one solution, a plurality of rollers are arranged around the edge of the second push plate; a sliding groove for the rollers to slide is opened on the inner wall of the storage cavity.

[0018] Specifically, the rollers are arranged at intervals in the depth direction of the storage cavity.

[0019] In one solution, a through port for the blocking cable to slide is opened on the inner wall of the storage cavity, and the through port is strip-shaped and extends along the depth direction of the storage cavity.

[0033] By providing an airbag package on the outer shell, when the anti-collision buffer vehicle is severely impacted, that is, after all three buffer mechanisms are damaged under the action of the impact force and there is still an impact force acting on the outer shell, the airbag package is triggered to deploy the airbag to counteract the action of the impact force on the outer shell, reducing the deformation of the outer shell and ensuring the safe use of the battery body. At the same time, the energy-absorbing structure provided on the outer shell can effectively absorb the impact force, that is, the outside of the outer shell deforms by absorbing energy under the action of the impact force, but the inside of the outer shell remains unchanged, ensuring the safe use of the battery body and improving the protection level of the battery body.

[0053] This application makes improvements and innovations and proposes the following embodiments.

[0054] In some embodiments, please refer to Figures 1 to 10 , a collision buffer of a collision buffer vehicle is provided, including a vehicle body 1 having a storage cavity 11, and further including:

[0055] A first buffer mechanism 2, the first buffer mechanism 2 includes a housing 21, a connecting plate 22 located inside the housing 21, and a plurality of first dampers 23; one ends of the plurality of first dampers 23 are all hingedly arranged inside the housing 21, and the other ends are all hinged to the connecting plate 22;

[0056] A second buffer mechanism 3, the second buffer mechanism 3 includes a first push plate 31, a plurality of second dampers 32, and a second push plate 33; the first push plate 31 is fixedly connected to the housing 21; the first push plate 31 and the second push plate 33 are arranged at intervals, and each second damper 32 is located between the first push plate 31 and the second push plate 33, and one end of the second damper 32 is fixedly connected to the first push plate 31, and the other end is fixedly connected to the second push plate 33;

[0057] A third buffer mechanism 4; the third buffer mechanism 4 includes a blocking cable 41 and two third dampers 42; the third damper 42 has a moving end; both ends of the blocking cable 41 are respectively fixedly connected to the moving ends of the two third dampers 42; a bottom plate 43 is fixedly connected to the second push plate 33, and the bottom plate 43 abuts against the blocking cable 41;

[0058] A battery assembly 9, the battery assembly 9 is arranged inside the vehicle body 1, and the battery assembly 9 includes a battery body 91 and an outer housing 92; the battery body 91 is fixedly installed inside the outer housing 92, and an airbag package 93 is fixedly arranged on the outer housing 92, and the airbag package 93 is close to the storage cavity 11; the outer housing 92 has an energy absorption structure; the battery body 91 is electrically connected to the third buffer mechanism 4.

[0059] Among them, a part of the first damper 23 is hinged to the first push plate 31, and the other part of the first damper 23 is hinged to the inner wall of the housing 21; each second damper 32 is uniformly arranged at intervals on the second push plate 33. A plurality of first dampers 23 are arranged at intervals around the circumference of the connecting plate 22.

[0060] Among them, when the anti-collision buffer is impacted, the first buffer structure 2 absorbs the impact force first, and then the impact force is transmitted to the second buffer mechanism 3 and the third buffer mechanism 4. Moreover, the damping capacities of the first damper 23, the second damper 32, and the third damper 42 increase in sequence. This setting can effectively protect the service lives of the second damper 32 and the third damper 42. The first damper 23 receives the largest impact force and is most likely to be damaged. However, since the first damper 23 is arranged at the front end, it is convenient to replace and easy to repair. By absorbing the impact force with the first damper 23, the impact on the second damper 32 and the third damper 42 is reduced. The service lives of the second damper 32 and the third damper 42 are prolonged.

[0061] A plurality of first dampers 23 can not only be distributed around in the horizontal plane, but also be distributed around in the vertical plane; or be distributed around in any plane. This setting can effectively absorb the impact forces from all directions and improve the adaptability of the anti-collision buffer.

[0062] Specifically, the first dampers 23 are arranged at intervals in the horizontal direction, that is, arranging multiple layers of first dampers 23 can improve the damping effect on the impact force and ensure the service life of a single damper.

[0063] By setting three buffer mechanisms to jointly absorb the impact force, when the impact force impacts the buffer mechanisms, a plurality of first dampers 23, a plurality of second dampers 32, and a plurality of third dampers 42 of the three buffer mechanisms jointly exert a damping effect. The anti-collision buffer deforms slowly, and the deformation of the housing 21 is elastic deformation and can automatically return to its original state after the impact force is withdrawn. Under the combined action of the three dampers, the three buffer mechanisms only undergo elastic deformation instead of plastic deformation, and can return to their original states after the impact is withdrawn.

[0064] A plurality of first dampers 23 are distributed around on the connecting plate 22, which can ensure that when the housing 21 receives impact forces from different directions, the impact forces can still be damped and relieved, reducing the shear force acting on the second buffer mechanism 3 and the third buffer mechanism 4.

[0065] The second buffer mechanism 3 and the third buffer mechanism 4 mainly relieve the impact force acting in the depth direction of the receiver.

[0066] Meanwhile, setting up the storage cavity 11 can help store the anti-collision buffer. At the same time, the storage cavity 11 provides space for the anti-collision buffer to move when impacted by an impact force, preventing the third buffer mechanism 4 from directly hitting the vehicle body 1.

[0067] By arranging an airbag pack 93 on the outer housing 92, when the anti-collision buffer vehicle is violently impacted, that is, after all three buffer mechanisms are damaged under the action of the impact force and there is still an impact force acting on the outer housing 92, the airbag pack 93 is triggered to operate, ejecting the airbag to counteract the action of the impact force on the outer housing 92, reducing the deformation of the outer housing 92, and ensuring the safe use of the battery body 91. At the same time, the energy-absorbing structure arranged on the outer housing 92 can effectively absorb the action of the impact force, that is, the outside of the outer housing 92 absorbs energy and deforms under the action of the impact force, but the inside of the outer housing remains unchanged, ensuring the safe use of the battery body 91. The protection level of the battery body 91 is improved.

[0068] Specifically, the airbag pack 93 is an airbag used in an automobile, and the energy-absorbing structure is an energy-absorbing material 96 filled in the outer housing 92. That is, the outer housing 92 has a double-layer structure, which is composed of two spaced-apart plate bodies 95. The plate body 95 located on the outer layer serves as the outside of the outer housing, and the thickness of the plate body 95 located on the outer layer is less than that of the other plate body 95. The energy-absorbing material 96 is filled between the two plate bodies 95.

[0069] The energy-absorbing material 96 has a negative Poisson's ratio structure. The energy-absorbing filler with a negative Poisson's ratio structure has good energy-absorbing effects.

[0070] A reinforcing beam 94 is further arranged inside the outer housing 92. Both ends of the reinforcing beam 94 are fixed with reinforcing plates 97, and the reinforcing plates 97 are fixedly connected to the inner wall of the outer housing 92. The extending direction of the reinforcing beam 94 is the depth direction of the storage cavity 11. The cooperation of the reinforcing beam 94 and the reinforcing plates 97 can sufficiently reduce the influence of the impact on the internal deformation of the outer housing 92 and ensure the safe use of the battery body 91.

[0071] In one embodiment, the second buffer mechanism 3 further includes a first baffle 34 and a second baffle 35. The first baffle 34 is fixedly connected to the first push plate 31 and is arranged around the edge of the first push plate 31; the second baffle 35 is fixedly connected to the second push plate 33 and is arranged around the edge of the second push plate 33; the end of the second baffle 35 far from the second push plate 33 is located in the cavity surrounded by the first baffle 34, and the first baffle 34 can move relative to the second baffle 35. The first baffle 34 and the second baffle 35 are arranged to enclose the second damper 32, reducing the entry of impurities near the second damper 32 and affecting the normal use of the damper.

[0072] Specifically, one end of the second baffle 35 is fixedly connected to the second push plate 33, and the other end is located in the cavity surrounded by the first baffle 34. When the second damper 32 extends to its longest state, a part of the second baffle 35 is still in the cavity surrounded by the first baffle 34, which can reduce the entry of dust or large particulate impurities into the cavity and affect the normal use of the second damper 32.

[0073] In one embodiment, the third buffer mechanism 4 further includes a plurality of first fixed pulleys 44; the first fixed pulleys 44 are rotatably connected to the vehicle body 1, and the blocking cable 41 abuts against the bottom plate 43 after passing through the first fixed pulleys 44. By providing the first fixed pulleys 44, the wear of the blocking cable 41 on the bottom plate 43 can be reduced, and the service lives of the bottom plate 43 and the blocking cable 41 can be prolonged.

[0074] Specifically, a slot or a tube body is provided on the bottom plate 43, the blocking cable 41 is clamped in the slot or passes through the tube body, and the blocking cable 41 can slide relative to the slot or the tube body. Providing the slot or the tube body can limit the displacement of the blocking cable 41 on the bottom plate 43, avoid the situation that the blocking cable 41 slides out of the bottom plate 43, ensure that the force application position of the blocking cable 41 on the bottom plate 43 remains unchanged, and ensure that the impact force received by the bottom plate 43 is reasonable.

[0075] A second fixed pulley 45 is provided at a position close to the opening of the storage cavity 11. The blocking cable 41 enters the first fixed pulley 44 after passing through the second fixed pulley 45. The second fixed pulley 45 is located outside the storage cavity 11 and is used to change the pulling direction of the blocking cable 41.

[0076] In one embodiment, a plurality of rollers 47 are arranged around the edge of the second push plate 33; a sliding groove 48 for the rollers 47 to slide is formed on the inner wall of the storage cavity 11. Providing the rollers 47 can reduce the friction when the second push plate 33 moves in the storage cavity 11 and prolong the service lives of the second push plate 33 and the storage cavity 11. The circumferential distribution of the plurality of rollers 47 can ensure that when the push plate is subjected to an impact force, the force can be evenly and reasonably transmitted to the storage cavity 11.

[0077] Specifically, the rollers 47 are arranged at intervals in the depth direction of the storage cavity 11, and this arrangement can reduce the torsional stress impact on the second push plate 33 caused by the gravity of the three buffer mechanisms on the rollers 47.

[0078] In one embodiment, a through opening 12 for the blocking cable 41 to slide is formed on the inner wall of the storage cavity 11. The through opening 12 is strip-shaped and extends along the depth direction of the storage cavity 11. Providing the through opening 12 can facilitate the sliding of the blocking cable 41 and also limit the movement of the blocking cable 41 on the bottom plate 43, ensuring that the force application position of the blocking cable 41 on the bottom plate 43 remains basically unchanged.

[0079] In one embodiment, the outer shell 21 is made of an elastic material. The outer shell 21 made of an elastic material has a high elastic deformation, which facilitates the first damper 23 to absorb the impact force, and can rebound to its original state after the impact force is removed, increasing the number of reuse times.

[0080] Specifically, the arc shape is convex outward. The convex arc shape can improve the strength of the outer shell 21.

[0081] The outer shell 21 is made of rubber, which has low cost, good elasticity and wear resistance.

[0082] In one embodiment, the first damper 23, the second damper 32 and the third damper 42 are all hydraulic dampers 5. Using the hydraulic damper 5 can cope with a large impact force, and the hydraulic damper 5 is practical and reliable.

[0083] Specifically, the hydraulic damper 5 includes a hydraulic cylinder 51, a telescopic rod 52 and a piston 53; the piston 53 divides the hydraulic cylinder 51 into two chambers, and both chambers are filled with hydraulic oil. A through hole 54 is opened on the piston 53. When the piston 53 moves, the hydraulic oil will flow through the through hole 54 to the other chamber, that is, when the piston 53 is subjected to an impact force, it will squeeze the hydraulic oil in the corresponding chamber, and the hydraulic oil will flow through the through hole 54 to the other chamber. Due to the influence of the aperture of the through hole 54, the piston 53 moves slowly, thereby realizing the buffering of the impact force, increasing the action time and reducing the action effect.

[0084] The number of the arresting cables 41 is two. The two arresting cables 41 are arranged at intervals on the bottom plate 43, and the two arresting cables 41 are symmetrically arranged on both sides of the output end of the hydraulic cylinder 51 respectively. A third fixed pulley 46 is also arranged on the hydraulic cylinder 51. The arresting cable 41 passes through the third fixed pulley 46, the second fixed pulley 45 and the first fixed pulley 44 in sequence and then enters the card slot or the pipe body. Arranging two arresting cables 41 can make the force on the moving end of the third damper 42 more reasonable and reduce the torsional stress generated by the arresting cable 41 on the moving end. At the same time, the two arresting cables 41 are arranged at intervals on the bottom plate 43, which can disperse the force on the bottom plate 43 and reduce the stress concentration.

[0085] A solenoid valve is provided on the through hole 54 of the piston 53 of the third damper 42 to control the opening degree of the through hole 54. By setting the solenoid valve to control the opening degree of the through hole 54, the moving speed of the piston 53 when it is subjected to an impact force can be controlled, that is, when the impact force is the same, the larger the opening degree of the through hole 54, the faster the piston 53 moves. Therefore, it is necessary to adjust the moving speed of the piston 53 according to different impact strengths to ensure the best buffering effect.

[0086] Alternatively, oil pipelines 55 are correspondingly connected to both of the two chambers separated by the piston 53 in the hydraulic cylinder 51 of the third damper 42; a flow regulating valve 56 is provided on each oil pipeline 55; each oil pipeline 55 is connected to an oil pump 58, and the oil pump 58 is located in the fuel tank 57. This method has relatively low requirements for the flow regulating valve 56, that is, there are more flow regulating valves 56 to choose from, and there is no need to use a small and delicate flow regulating valve 56.

[0087] A processor is also provided. Pressure sensors are provided at the bottoms of each first damper 23, each second damper 32, and each third damper 42. Each pressure sensor and each flow regulating valve are electrically connected to the processor. When each first damper 23, each second damper 32, and each third damper 42 are subjected to impact forces, the corresponding pressure sensors will transmit pressure signals to the processor. After calculating the pressure of the pressure sensors, the processor outputs corresponding signals to the flow regulating valves to adjust the through-hole openings of the dampers, so as to ensure that each damper can obtain a reasonable pressure and reasonably distribute the impact force to each damper for buffering, avoiding the situation that some dampers are damaged due to excessive impact force.

[0088] The processor is electrically connected to the battery body 91.

[0089] At the same time, through the cooperation of the flow regulating valve 56 and the oil pump 58, by injecting hydraulic oil corresponding to the two chambers, the piston 53 can be pushed to any position within the stroke of the hydraulic cylinder 51 and stopped, realizing the control of the movement of the piston 53, and further controlling the movement of the arresting cable 41. The pulled arresting cable 41 will push the second push plate 33 towards the opening of the storage cavity 11, realizing the push-out of the anti-collision buffer, without the need for manual pulling, reducing the labor intensity of the staff.

[0090] The flow regulating valve 56 and the oil pump 58 are both electrically connected to the battery body 91.

[0091] When it is necessary to retract the anti-collision buffer, the staff can push the anti-collision buffer into the storage cavity 11.

[0092] In one embodiment, a return spring 59 is provided inside each of the first damper 23, the second damper 32, and the third damper 42. By setting the return spring 59, the anti-collision buffer can automatically rebound and reset after use, realizing repeated use without the need for manual reset.

[0093] Specifically, the reset spring 59 provided inside the third damper 42 cannot push the entire anti-collision buffer out of the storage cavity 11. The reset spring 59 provided inside the third damper 42 cannot push the entire anti-collision buffer out of the storage cavity 11, which can prevent the entire anti-collision buffer from falling out of the storage cavity 11. Moreover, since the elastic force of the reset spring 59 of the third damper 42 is insufficient, less force is required to manually retract the anti-collision buffer, thus reducing the work intensity of the staff.

[0094] In one embodiment, it further includes a pushing mechanism 6 for pushing the second push plate 33 out of the storage cavity 11, a retracting rope 7, and a first driving motor 8; one end of the retracting rope 7 is connected to the second push plate 33, and the other end is fixedly connected to the output end of the first driving motor 8. The pushing action of the anti-collision buffer is realized through the pushing mechanism 6 without manual pushing. Then, in cooperation with the retracting rope 7 and the first driving motor 8, the retraction of the anti-collision buffer is realized, achieving the automation of the pushing and retraction of the anti-collision buffer, without manual pushing and pulling, and reducing the labor intensity of the staff.

[0095] In one embodiment, the pushing mechanism 6 includes: a driving chain 61, a pushing block 62, and a second driving motor 63; the second driving motor 63 is in transmission connection with the driving chain 61; the pushing block 62 is fixedly connected to the driving chain 61; the pushing block 62 can abut against the bottom plate 43. The pushing mechanism 6 realizes pushing the bottom plate 43 towards the opening direction of the storage cavity 11 through the cooperation of the driving chain 61, the pushing block 62, and the second driving motor 63, and its structure is simple and reasonably designed.

[0096] Specifically, the outside of the storage cavity 11 is also a hollow structure for accommodating the pushing mechanism 6, the third damper 42, etc.

[0097] Specifically, both the first driving motor 8 and the second driving motor 63 are electrically connected to the battery body 91.
