Tiltable and modular anti-collision buffer device and anti-collision buffer vehicle

Abstract

This application provides a flip-up, modular anti-collision buffer device and an anti-collision buffer vehicle. It consists of multiple buffer modules arranged sequentially from front to back, with a rotating mechanism between adjacent buffer modules. This rotating mechanism flips the rear buffer module to the top of the front buffer module. When not in use, the rotating mechanism flips the rear buffer module to the top of the front buffer module, converting the horizontally arranged buffer modules into a vertical configuration. Then, a hydraulic cylinder drive on the buffer vehicle rotates the anti-collision device 90°, allowing the buffer modules to be sequentially loaded into the rear cargo bed. This reduces wind resistance and eliminates height restrictions.

Description

[0001] This application is a divisional application. The original application has the application number 2021114006874 and the application date is November 24, 2021. The invention patent title is: Impact-resistant and durable anti-collision device and anti-collision buffer vehicle. Technical Field

[0002] This application relates to the technical field of crash buffer vehicle equipment, specifically to a flip-up modular crash buffer device and a crash buffer vehicle. Background Technology

[0003] During road construction, crash barriers are placed behind the construction site to ensure the safety of construction workers. Existing crash barriers consist of a vehicle body and a crash protection device located at the rear of the vehicle body. During operation, a hydraulic cylinder drives the crash protection device to a horizontal position. When a vehicle collides with the crash barrier from behind, the crash protection device cushions the moving vehicle, reducing injury to construction workers. After the operation is completed, the crash protection device flips back to a position perpendicular to the vehicle body.

[0004] However, existing anti-collision devices have limited anti-collision capabilities, and their buffering stability and energy absorption effects are generally poor. Furthermore, after the operation is completed, the anti-collision device flips to a position perpendicular to the vehicle body, causing the anti-collision vehicle to experience greater wind resistance when driving or parking, making it prone to rollover and causing vehicle damage. In addition, it cannot pass through height-restricted areas.

[0005] Therefore, there is an urgent need to further improve the existing anti-collision devices. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, this application provides a flip-up, modular anti-collision buffer device.

[0007] Another objective of this application is to provide a crash buffer vehicle.

[0008] A flip-up, modular anti-collision buffer device includes multiple buffer modules arranged sequentially from front to back, and a rotating mechanism is provided between two adjacent buffer modules. The rotating mechanism is used to flip the buffer module located on the rear side to the top of the buffer module located on the front side.

[0009] As described above, in the flip-up modular anti-collision buffer device, the rotating mechanism is located on the left and right sides of the buffer module, with one end hinged to the buffer module located on the front side and the other end hinged to the buffer module located on the rear side.

[0010] As described above, in the flip-up modular anti-collision buffer device, the upper end of the rotating mechanism is hinged to the buffer module located on the front side, and the lower end is hinged to the buffer module located on the rear side.

[0011] As described above, the flip-type modular anti-collision buffer device has multiple rotating mechanisms arranged in parallel on the side walls of two adjacent buffer modules.

[0012] As described above, the flip-up modular anti-collision buffer device has an upper hinge seat on the side wall of the buffer module and a lower hinge seat located below the upper hinge seat.

[0013] The rotating mechanism includes a connecting rod whose front end is hinged to the upper hinge seat on the front side of the buffer module, and whose rear end is hinged to the lower hinge seat on the rear side of the buffer module.

[0014] As described above, the flip-up combination anti-collision buffer device has an anti-rotation part on the side wall of the buffer module. The anti-rotation part is used to prevent the buffer module located on the rear side from flipping to the front side of the buffer module located on the front side through the rotation mechanism.

[0015] In the aforementioned reversible modular anti-collision buffer device, the connecting rod is a telescopic structure.

[0016] As described above, the flip-up modular anti-collision buffer device has a hinge hook in the middle of the front side of the buffer module and an upwardly protruding hinge protrusion in the middle of the rear side. The hinge hook on the rear side of the buffer module can be hooked onto the hinge protrusion on the front side of the buffer module.

[0017] The number of buffer modules in the flip-up modular anti-collision buffer device described above is 3-5.

[0018] The crash buffer vehicle includes a vehicle body, and the rear end of the vehicle body is provided with the aforementioned flip-up modular crash buffer device. The crash buffer vehicle also includes a drive device disposed on the vehicle body and capable of reciprocatingly driving the flip-up modular crash buffer device to rotate relative to the vehicle body. The drive device can drive the flip-up modular crash buffer device to rotate to a horizontal or vertical state.

[0019] Compared with the prior art, the beneficial effects of this application are as follows:

[0020] 1. This application sets up multiple buffer modules arranged sequentially from front to back, with a rotating mechanism between adjacent buffer modules. The rotating mechanism is used to flip the buffer module located on the rear side to the top of the buffer module located on the front side. When not in use, the multiple buffer modules arranged in the horizontal direction can be converted into a vertical mode by flipping the buffer module located on the rear side to the top of the buffer module located on the front side through the rotating mechanism. Then, the anti-collision device is driven by the hydraulic cylinder drive device on the buffer vehicle to rotate 90°, so that the buffer modules can be loaded into the rear truck bed in sequence, which can reduce wind resistance and eliminate height restriction situations.

[0021] 2. The anti-collision buffer vehicle of this application is equipped with a flip-up and modular anti-collision buffer device at the rear of the vehicle body, which can sequentially install the buffer modules into the rear truck bed to reduce wind resistance and eliminate height restriction situations.

[0034] like Figure 1-11As shown, the flip-up combination anti-collision device includes multiple buffer modules 1 arranged sequentially from front to back. A rotating mechanism 6 is provided between two adjacent buffer modules 1. The rotating mechanism 6 is used to flip the buffer module 1 located on the rear side to the top of the buffer module 1 located on the front side.

[0035] In existing designs, after operation, the anti-collision device flips to a position perpendicular to the vehicle body, resulting in significant wind resistance when the anti-collision vehicle is driving or parked, making it prone to rollover and causing vehicle damage. Furthermore, it cannot pass through height-restricted areas. This application addresses this by configuring multiple buffer modules 1 arranged sequentially from front to back, with a rotating mechanism 6 between adjacent buffer modules 1. The rotating mechanism 6 flips the rear buffer module 1 to the top of the front buffer module 1. When not in use, the rotating mechanism 6 flips the rear buffer module 1 to the top of the front buffer module 1, converting the horizontally arranged buffer modules 1 into a vertical configuration. Then, the hydraulic cylinder drive device on the buffer vehicle rotates the anti-collision device 90°, allowing the buffer modules 1 to be sequentially loaded into the rear cargo bed, reducing wind resistance and eliminating height-restricted situations.

[0036] Preferably, the rotating mechanism 6 is located on the left and right sides of the buffer module 1, with one end hinged to the buffer module 1 located on the front side and the other end hinged to the buffer module 1 located on the rear side. By providing rotating mechanisms 6 on both sides of the buffer module 1, the buffer module 1 located on the rear side can be rotated to the upper side of the buffer module 1 located on the front side, and then the buffer module can be rotated into the truck bed by the drive device 5 on the buffer vehicle.

[0037] Preferably, the upper end of the rotating mechanism 6 is hinged to the buffer module 1 located on the front side, and the lower end is hinged to the buffer module 1 located on the rear side. Due to the abutting arrangement between the buffer modules 1, by setting the rotating mechanism in the direction from rear-low to front-up, the buffer module 1 located on the rear side can be flipped to the upper side of the buffer module located on the front side, but the reverse is not possible.

[0038] Preferably, a plurality of parallel rotating mechanisms 6 are provided on the sidewalls of two adjacent buffer modules 1. In this embodiment, two rotating mechanisms are provided between the two buffer modules 1 on each side. This design prevents the buffer module 1 located on the rear side from rotating forward or backward along the hinge.

[0039] Preferably, the buffer module 1 has an upper hinge seat 12 on its side wall and a lower hinge seat 13 located below the upper hinge seat 12; the rotating mechanism 6 includes a connecting rod 61 whose front end is hinged to the upper hinge seat 12 on the front buffer module 1 and whose rear end is hinged to the lower hinge seat 13 on the rear buffer module 1. By hinged to the buffer modules 1 on the adjacent sides by the connecting rod 61, the rear buffer module can be flipped to the top of the front buffer module.

[0040] Preferably, the buffer module 1 has an anti-rotation part 14 on its side wall. The anti-rotation part 14 is used to prevent the buffer module 1 located at the rear from flipping to the front of the buffer module 1 located at the front through the rotating mechanism 6. The purpose of setting the anti-rotation part is to prevent the rear buffer module from continuing to rotate forward to the front end of the front buffer module when the rear buffer module rotates to the front buffer module, thus affecting the folding effect.

[0041] Preferably, the connecting rod 61 is a telescopic structure. By setting the connecting rod 61 to a telescopic mode, it can descend to the top of the front buffer module when the rear buffer module rotates to the top of the front buffer module, which facilitates storage.

[0042] Preferably, the buffer module 1 has a hinge hook 71 at the center of its front side and an upwardly protruding hinge protrusion 72 at the center of its rear side. The hinge hook 71 on the rear side of the buffer module 1 can be hooked onto the hinge protrusion 72 on the front side of the buffer module 1. With this design, the rear side buffer module 1 and the front side buffer module 1 can be kept on the same horizontal plane. By hooking the rear side buffer module's hinge hook 71 onto the front side buffer module's hinge protrusion 72, the two are kept on the same horizontal plane. Since it is a hook, it does not affect the rotation mechanism of the two.

[0043] Furthermore, a rotating mechanism 6 is provided on the left and right side walls of the two adjacent buffer modules 1. The rotating mechanism 6 is used to elastically limit the rotation of the buffer module 1 located on the rear side relative to the buffer module 1 located on the front side. By setting the rotating mechanism 6, the buffer module 1 on the rear side can be kept directly behind the buffer module 1 on the front side, avoiding displacement before impact. At the same time, the rotating mechanism 6 is an elastic structure, which can adapt to the displacement during the impact when a vehicle from behind hits it, thus playing an elastic buffering role.

[0044] Preferably, the buffer module 1 has an upper hinge seat 12 and a lower hinge seat 13 on its side wall; the rotating mechanism 6 includes a connecting rod 61 whose front end is hinged to the upper hinge seat 12 on the front side of the buffer module 1 and whose rear end is hinged to the lower hinge seat 13 on the rear side of the buffer module 1, and the connecting rod 61 is a telescopic structure. The front buffer module 1 and the rear buffer module 1 are connected by the connecting rod 61.

[0045] Preferably, the number of buffer modules 1 is 3-5; this application sets multiple buffer devices, so after a collision, only the damaged buffer module needs to be replaced locally, without replacing the entire buffer device, which improves maintenance efficiency and reduces costs.

[0046] The rear buffer module 1 can rotate 5°-15° to the left or right relative to the front buffer module 1. This design allows for offset by a certain angle to adapt to the impact angle.

[0047] Preferably, the buffer device includes a mounting plate 3 for connecting to the rear end of the vehicle and a buffer module 1 disposed on the rear side of the mounting plate 3 for absorbing the energy generated during a vehicle collision. The flip-up modular anti-collision buffer device also includes an anti-collision module 4 disposed between the mounting plate 3 and the buffer module 1. The anti-collision module 4 includes an anti-collision housing 40. A front anti-collision group 41 is disposed inside the anti-collision housing 40 near the mounting plate 3, and a rear anti-collision group 42 is disposed inside the anti-collision housing 40 near the buffer module 1. The front anti-collision group 41 and the rear anti-collision group 42 are disposed opposite to each other. When the buffer module 1 moves closer to the mounting plate 3, the rear anti-collision group 42 drives the buffer module 1 to move away from the mounting plate 3, and the front anti-collision group 41 drives the mounting plate 3 to move away from the buffer module 1.

[0048] This application provides an anti-collision module 4 between the buffer module 1 and the mounting plate 3. The anti-collision module 4 includes a front anti-collision group 41 disposed on the side of the mounting plate 3 and a rear anti-collision group 42 disposed on the side of the buffer module 1. When the buffer module 1 is impacted, the buffer module 1 drives the rear anti-collision group 42 to move closer to the mounting plate 3 and the front anti-collision group 41. At this time, through the repulsive action between the rear anti-collision group 42 and the front anti-collision group 41, the rear anti-collision group 42 drives the buffer module 1 to move away from the mounting plate 3, and the front anti-collision group 41 drives the mounting plate 3 to move away from the buffer module 1. This design prevents the buffer module 1 from hitting the mounting plate 3, thereby protecting the hydraulic cylinder drive device. By providing the anti-collision module 4, this application can protect the hydraulic cylinder drive device when it is hit by a rear vehicle, preventing the hydraulic cylinder drive device from being damaged and scrapped due to the impact, and reducing replacement costs.

[0049] Preferably, the front anti-collision assembly 41 is provided with a front magnetic element 411, and the rear anti-collision assembly 42 is provided with a rear magnetic element 421. The front magnetic element 411 and the rear magnetic element 421 have the same magnetic poles at opposite ends and repel each other. This application utilizes the principle of like poles repelling in magnetic materials. The rear magnetic element 421 and the front magnetic element 411 are respectively provided on the buffer module 1 and the mounting plate 3, and are arranged with the same S pole or N pole facing each other. When the buffer module 1 receives a high-speed impact, the buffer module 1 drives the rear magnetic element 421 to move closer to the front magnetic element 411. Through the principle of like poles repelling, the rear magnetic element 421 provides a repulsive force, preventing the buffer module 1 from colliding with the hydraulic cylinder drive device, thereby protecting the hydraulic cylinder drive device.

[0050] Preferably, the front anti-collision assembly 41 further includes a front base 412 disposed on the side of the anti-collision housing 40 near the mounting plate 3. The front base 412 has an inwardly recessed front groove, and the front magnetic component 411 is embedded in the front groove. By setting the front base 412, the front magnetic component 411 is fixed. Preferably, after the front magnetic component 411 is embedded in the front base 412, its surface is sealed with polyurethane resin to achieve a protective effect.

[0051] The rear anti-collision assembly 42 further includes a rear base 422 disposed on the side of the anti-collision housing 40 near the buffer module 1. The rear base 422 has an inwardly recessed rear groove, and the rear magnetic component 421 is embedded in the rear groove. By setting the rear base 422, the rear magnetic component 421 is fixed. Preferably, after the rear magnetic component 421 is embedded in the rear base 422, its surface is sealed with polyurethane resin to achieve a protective effect.

[0052] Preferably, the front base 412 is provided with a plurality of front slots arranged in a rectangular array, and a plurality of front magnetic components 411 are provided and respectively embedded in the plurality of front slots, and the magnetic poles of two adjacent front magnetic components 411 are opposite; the magnetic poles of adjacent magnets are opposite, that is, the magnetic poles of diagonal magnets are the same, both being N poles or S poles, while the magnetic poles of another diagonal magnet are the same, both being S poles or N poles. The design of the magnet array arrangement and the opposite magnetic poles of adjacent magnets has the advantage of stronger magnetic force and can stably provide repulsive force.

[0053] The rear base 422 has a plurality of rear slots arranged in a rectangular array. A plurality of rear magnetic components 421 are provided and respectively embedded in the plurality of rear slots, and the magnetic poles of two adjacent rear magnetic components 421 are opposite. The magnetic poles of adjacent magnets are opposite, that is, the magnetic poles of diagonal magnets are the same, both being N poles or S poles, while the magnetic poles of another diagonal magnet are the same, both being S poles or N poles. The design of the magnet array arrangement with the magnetic poles of adjacent magnets being opposite has the advantage of stronger magnetic force and can stably provide repulsive force.

[0054] Preferably, the front anti-collision group 41 is provided in multiple groups along the vertical direction, including an upper front anti-collision group 415 located on the upper side, a middle front anti-collision group 416 located in the middle, and a lower front anti-collision group 417 located on the lower side. The upper front anti-collision group 415 has an upper front inclined surface 413 that is inclined to the lower front side on the rear side of the front base 412, and the front magnetic element 411 is inclined on the upper front inclined surface 413. The lower front anti-collision group 417 has a lower front inclined surface 414 that is inclined to the lower rear side on the rear side of the front base 412, and the front magnetic element 411 is inclined on the lower front inclined surface 414.

[0055] The rear anti-collision assembly 42 is provided in multiple sets along the vertical direction, including an upper rear anti-collision assembly 425 located on the upper side and opposite to the upper front anti-collision assembly 415, a middle rear anti-collision assembly 426 located in the middle and opposite to the middle front anti-collision assembly 416, and a lower rear anti-collision assembly 427 located on the lower side and opposite to the lower front anti-collision assembly 417. The rear base 422 on the upper rear anti-collision assembly 425 has an upper rear inclined surface 423 that slopes downwards and forwards on the front side, and the rear magnetic component 421 is inclined on the upper rear inclined surface 423. The rear base 422 on the lower rear anti-collision assembly 427 has a lower rear inclined surface 424 that slopes downwards and backwards on the front side, and the rear magnetic component 421 is inclined on the lower rear inclined surface 424.

[0056] Both the upper front bumper assembly 415 and the upper rear bumper assembly 425 are designed to be tilted forward and downward. When impacted, they can provide a repulsive force in the forward and downward direction, preventing them from being repelled upward due to the repulsive force. Similarly, both the lower front bumper assembly 417 and the lower rear bumper assembly 427 are designed to be tilted forward and downward. When impacted, they can provide a repulsive force in the forward and downward direction, preventing them from being repelled downward due to the repulsive force. This design ensures that the total repulsive force is directed forward and backward, thus achieving a stable repulsive effect.

[0057] Preferably, multiple sets of the front anti-collision group 41 and the rear anti-collision group 42 are provided and distributed at equal intervals. In this application, two sets of front anti-collision groups 41 and the rear anti-collision group 42 are provided on the upper side, three sets of front anti-collision groups 41 and the rear anti-collision group 42 are provided in the middle, and two sets of front anti-collision groups 41 and the rear anti-collision group 42 are provided on the lower side. Through the design of the interval arrangement, a stable repulsive force can be provided.

[0058] Preferably, the anti-collision housing 40 includes a front housing 401 connected to the mounting plate 3, a rear housing 402 connected to the buffer module 1, and an intermediate housing 403 connected between the front housing 401 and the rear housing 402. The intermediate housing 403 is made of a flexible material. By fixing the front anti-collision assembly 41 and the rear anti-collision assembly 42 inside the front housing 401 and the rear housing 402 respectively, and connecting the front housing 401 and the rear housing 402 using the intermediate housing 403, and by designing the intermediate housing 403 as a flexible material, a buffer space can be provided in the event of a collision. The flexible material can be waterproof canvas or other elastic materials.

[0059] Preferably, the anti-collision module 4 further includes a guide group 43 disposed around the anti-collision housing 40 for guiding in the front-to-back direction. The guide group 43 includes a front sleeve 431 disposed on the front housing 401, a rear sleeve 432 disposed on the rear housing 402, and a guide rod 433 with its two ends respectively fitted inside the front sleeve 431 and the rear sleeve 432. A front reset member 434 is provided between the front housing 401 and the front end of the guide rod 433, and a rear reset member 435 is provided between the rear housing 402 and the rear end of the guide rod 433. By setting the guide group 43, a lateral guiding function is achieved, avoiding misalignment between the front housing 401 and the rear housing 402, which would affect the buffering effect.

[0060] Preferably, the anti-collision housing 40 is also filled with liquid. The anti-collision housing 40 is a sealed container, and by filling it with liquid, it achieves a water resistance effect, further improving the cushioning effect and protecting the drive device 5.

[0061] The preferred plurality of buffer modules 1 are hinged sequentially from front to back, and in two adjacent buffer modules 1, the buffer module 1 located on the rear side can rotate to the left or right relative to the buffer module 1 located on the front side.

[0062] In existing technologies, when a vehicle behind does not collide head-on with the anti-collision device, but instead impacts its left or right side, only one side of the anti-collision device is effective, resulting in reduced impact protection and inadequate buffering protection. This application addresses this by configuring multiple buffer modules 1 articulated sequentially from front to back. In any two adjacent buffer modules 1, the rear buffer module 1 can rotate to the left or right relative to the front buffer module 1. This design allows the rear buffer module to rotate relative to the front buffer module towards the impact point when the vehicle behind does not collide head-on. By adaptively adjusting the buffer angle based on the impact vehicle's position, the buffer module effectively protects the vehicle behind, providing excellent buffering protection.

[0063] Preferably, the middle portions of two adjacent buffer modules 1 are hinged by a hinge mechanism 7. In this application, the middle portion of the buffer module 1 is hinged. When the impact direction is to the left of the buffer module 1, the rear buffer module rotates to the left relative to the front buffer module to adapt to the impact position adjustment, transmitting the impact force to the entire buffer device and preventing only the left buffer device from having a buffering effect. The principle is the same when the impact direction is to the right.

[0064] Preferably, the hinge mechanism 7 includes a hinge hook 71 located at the center of the front side of the buffer module 1, and a hinge protrusion 72 protruding upwards at the center of the rear side of the buffer module 1. The hinge hook 71 on the rear side of the buffer module 1 is hinged to the hinge protrusion 72 on the front side of the buffer module 1. By providing the hinge protrusion 72 on the rear side of the buffer module 1 and the hinge hook 71 on the front side of the buffer module 1, the rear buffer module 1 is hinged to the front buffer module 1, allowing it to rotate to the left and right to adapt to the impact angle.

[0065] In another embodiment of this application, the hinge mechanism 7 includes a hinge hook 71 located at the center of the rear side of the buffer module 1, and a hinge protrusion 72 protruding upwards at the center of the front side of the buffer module 1. The hinge hook 71 on the front side of the buffer module 1 is hinged to the hinge protrusion 72 on the rear side of the buffer module 1. This design allows the rear buffer module 1 to be hinged to the front buffer module 1, enabling it to rotate to the left and right to accommodate impact angles.

[0066] Preferably, the front end face and / or rear end face of the buffer module 1 are provided with an arc-shaped portion 15. Preferably, either the front end face or the rear end face of the buffer module 1 is provided with an arc-shaped portion, through which the rear buffer module 1 can be hinged to the front buffer module 1, and can rotate to the left and right to adapt to the impact angle.

[0067] Preferably, the arc of the arc portion 15 is 100°-120°. This range prevents the final buffer module 1 from rotating to be perpendicular to the vehicle body.

[0068] Preferably, the number of buffer modules 1 is 3-5. This application provides multiple buffer devices, so after a collision, only the damaged buffer modules need to be replaced, eliminating the need to replace the entire buffer device, thus improving maintenance efficiency and reducing costs.

[0069] The crash buffer vehicle includes a vehicle body 2, and the rear end of the vehicle body 2 is provided with the aforementioned flip-up combined crash buffer device. The crash buffer vehicle also includes a drive device 5 disposed on the vehicle body 2 and capable of reciprocatingly driving the flip-up combined crash buffer device to rotate relative to the vehicle body 2. The drive device 5 can drive the flip-up combined crash buffer device to rotate to a horizontal or vertical state.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
