Referring to fig. 1, an assembled road crash pad is consistent with the prior art, the application is also provided with a collision mechanism 1, energy absorbing components 2 and a fixing mechanism 3 along the lane direction, wherein the energy absorbing components 2 are formed by arranging a plurality of energy absorbing components 2 in parallel along the lane direction, the energy absorbing components 2 are used for buffering the collision mechanism 1, so that the collision mechanism 1 can not only can move relatively to prevent and protect the safety of vehicles and drivers and passengers when being impacted, but also can limit the moving distance of the relative positions, and avoid the failure of sufficient deceleration effect on the vehicles.
The fixing mechanism 3 is used for fixing the device on the ground and ensuring that the device cannot deviate relative to the ground.
Specifically, the fixing mechanism 3 includes a ground screw embedded in the ground and an L-shaped plate, and a through hole is formed in the L-shaped plate for the ground screw so that the ground screw can be inserted into the through hole, and the L-shaped plate is ensured by the ground screw, that is, the fixing mechanism 3 is not moved in relative position as a whole.
Referring to fig. 2 and 14, unlike the prior art device, in the present application, two corrugated plates 4 are detachably connected to the front and rear ends of the collision mechanism 1, respectively, and the corrugated plates 4 can be detachably connected to the collision mechanism 1 in a form of matching with screws and nuts, so that the collision mechanism 1 can be detached from the corrugated plates 4 for transportation in the transportation process, and the detachable connection also enables the corrugated plates 4 to be individually replaced when the corrugated plates 4 and the collision mechanism 1 are deformed so as not to meet the expected setting in practice, thereby reducing the replacement cost.
The energy absorbing component 2 is located between two buckled plates 4, single energy absorbing component 2 and buckled plate 4 sliding connection, in practice because fixed establishment 3 position keeps unchanged, then when collision mechanism 1 receives the impact, a plurality of energy absorbing components 2 are not equal at horizontal plane displacement distance, specifically, because a plurality of energy absorbing components 2 all will be born the weight and take place the deformation, then the energy absorbing component 2 that is close to fixed establishment 3 more is the moving distance the less, and because collision mechanism 1 with the energy absorbing component 2 butt of furthest from fixed establishment 3, collision mechanism 1 is unanimous with buckled plate 4 mobile state, then need buckled plate 4 and fixed establishment 3 sliding connection, thereby single energy absorbing component 2 and buckled plate 4 sliding connection avoid when collision mechanism 1 receives the impact, buckled plate 4 takes place the stroke conflict with fixed establishment 3, energy absorbing component 2.
Specifically, the corrugated plate 4 is provided with a chute 5 along the length direction thereof, and the energy absorbing component 2 is embedded into the chute 5, so that sliding connection between the energy absorbing component 2 and the corrugated plate 4 can be realized.
Because of the existence of the sliding groove 5, the L-shaped plate in the fixing mechanism 3 can be provided with a bulge so as to realize sliding connection between the fixing mechanism 3 and the corrugated plate 4.
Please refer to fig. 3, 14, because the corrugated plate 4 is detachably connected with the collision mechanism 1, the corrugated plate 4 can be fixed on one side, so as to limit the corrugated plate 4 further, even if the corrugated plate is impacted by external force, the corrugated plate 4 can only do linear motion relative to the fixing mechanism 3, the end, close to the fixing mechanism 3, of the corrugated plate 4 is provided with a limit groove 6, the far-away ends of the two corrugated plates 4 are provided with limit plates 7 relative to the limit groove 6, and the relative distance between the corrugated plate 4 and the fixing mechanism 3 is limited by the limit plates 7, so that the corrugated plate 4 can only do linear motion relative to the fixing mechanism 3. Specifically, the limiting plate 7 is detachably connected with the fixing mechanism 3, so that the position of the limiting plate 7, namely, the distance between the limiting plate 7 and the fixing mechanism 3 is limited, and meanwhile, the limiting plate 7 is detachable, so that the corrugated plate 4 and the fixing mechanism 3 can be detached. Specifically, the limiting plate 7 and the fixing mechanism 3 can be detachably connected through screws and inserted bars, and the screws and the inserted bars penetrate through the limiting grooves 6.
Referring to fig. 1, 2 and 10, the plurality of energy absorbing components 2 are arranged in a rectangular array, so that the requirement on a single energy absorbing component 2 is further reduced while the buffering effect is ensured, meanwhile, the single energy absorbing component 2 is ensured to be miniaturized enough to be convenient for adjusting the same, meanwhile, the arrangement mode is different from the arrangement mode of the traditional parallel energy absorbing components 2, and even if a small number of energy absorbing components 2 are in a missing and damaged phenomenon, the arrangement mode of the rectangular array energy absorbing components 2 does not affect the whole energy absorbing effect too much, and the stability and reliability of the device are ensured.
Referring to fig. 4, the single energy absorbing component 2 includes a plurality of energy absorbing units 24 arranged in parallel, specifically referring to fig. 5, the single energy absorbing unit 24 is formed by splicing eight mutually hinged movable plates, that is, the whole energy absorbing unit 24 is in an octagonal structure, and in order to ensure that the plurality of energy absorbing components 2 can well complete the transmission process of the impact force, the movable plates are prevented from being deformed due to stress concentration, the movable plates should be vertically arranged at the near ends of the plurality of energy absorbing units 24 in the same horizontal plane, that is, two vertically movable plates which are symmetrically arranged in the single energy absorbing unit 24 should be used for completing the abutting process of different energy absorbing components 2.
Two movable plates which are symmetrically arranged in the eight movable plates are also selected, the slots 25 are formed in the two movable plates, and further, the movable plates with the slots 25 are also vertically arranged, so that a large enough abutting surface is ensured between a plurality of energy absorbing units 24 in a single energy absorbing component 2. Specifically, the energy absorbing unit 24 is formed by hinging eight movable plates, wherein four movable plates are vertically arranged, the four vertically arranged movable plates are symmetrical in pairs, and the four vertically arranged movable plates are not adjacent to each other.
The linkage rod 23 is jointly inserted into the slots 25 in the single energy-absorbing component 2, so that the plurality of energy-absorbing units 24 in the single energy-absorbing component 2 can synchronously move, the linkage rod 23 is prevented from being inclined due to the stress of the single energy-absorbing unit 24, sliding connection between the corrugated plate 4 and the movable plate is damaged, and meanwhile, the energy-absorbing units 24 can be supported by the linkage rod 23, so that the energy-absorbing units 24 can be located at specific positions according to expected values. Meanwhile, the movable plate is in sliding connection with the linkage rod 23, so that the single energy absorption unit 24 can be detached from the linkage rod 23 through sliding.
With continued reference to fig. 4, two ends of the linkage rod 23 are respectively sleeved with a length conversion mechanism 21, specifically, with reference to fig. 6, the length conversion mechanism 21 includes a conversion unit 211, the conversion unit 211 is consistent with the energy absorption unit 24 in structure, the conversion unit 211 is also formed by splicing eight movable plates hinged to each other, four movable plates in the eight movable plates in the conversion unit 211 are vertically arranged, the four vertically arranged movable plates are symmetrical in pairs, and the four vertically arranged movable plates are not adjacent to each other.
With continued reference to fig. 4, a compression spring I22 is disposed between the transforming unit 211 and the adjacent energy absorbing unit 24, and the compression spring I22 is sleeved outside the linkage rod 23, that is, the specific working principle of the energy absorbing component 2 of the present application is that the length of the length transforming mechanism 21 is changed by changing the distance between the upper and lower movable plates of the transforming unit 211, and as can be seen from fig. 2, the far ends of the two transforming units 211 are embedded into the chute 5, that is, the whole length of the energy absorbing component 2 cannot be changed, the length transforming of the length transforming mechanism 21 changes the compression amount of the compression spring I22, so that the total length of the plurality of energy absorbing units 24 is changed, and the width of the single energy absorbing component 2 can be controlled. The application can detach the single energy absorbing component 2 from the space between the two corrugated plates 4 by changing the width of the energy absorbing unit 24 and the length of the length changing mechanism 21, thereby being convenient for replacing the single energy absorbing component 2.
Referring to fig. 2 and 10, in order to ensure the portability of disassembly, the number of the energy absorbing components 2 in the same vertical plane is not more than four, so that a user can disassemble any energy absorbing component 2 at most twice.
In order to ensure the cushioning effect of the energy absorbing members 2, it is also necessary to limit the number of the energy absorbing members 2 in the same vertical plane to not less than one.
Meanwhile, referring to fig. 4, the center line of the transformation unit 211 is perpendicular to the center line of the energy absorbing units 24, so that when the plurality of energy absorbing units 24 are deformed due to the overall impact force, the transformation unit 211 does not affect the deformation of the energy absorbing units 24.
The mounting bar has a square longitudinal section, so that the specific forms of the energy absorbing unit 24 and the transformation unit 211 are limited, the energy absorbing unit can be directly mounted, and the energy absorbing unit cannot be changed in the use process.
Referring to fig. 7, two movable plates at the upper and lower ends of the conversion unit 211 are provided with mounting grooves 212, a wire rope 216 is inserted into the mounting grooves 212, and the wire rope 216 is not blocked from moving relative to the conversion unit 211 by the mounting grooves 212, so that the wire rope 216 can be freely separated from and embedded in the movable plates.
The remote ends of the two steel wire ropes 216 are fixedly connected with an adjusting plate 217 respectively, and the adjusting plate 217 is fixedly connected with the corresponding movable plate, so that the corresponding adjusting plate 217 can be controlled by pulling the steel wire ropes 216, the relative distance between the two movable plates can be changed through the steel wire ropes 216, and the length of the length changing mechanism 21 can be controlled to meet the expectations. Meanwhile, in practice, the reaction force of the compression spring to the conversion unit 211, that is, the two movable plates at the upper end and the lower end always have a trend of moving towards opposite directions, so that the pressing force between the movable plate and the adjusting plate 217 can be utilized to ensure that the adjusting plate 217 can not move relative to the movable plate at will in practice, and the adjusting and limiting effects of the adjusting plate 217 on the movable plate are ensured.
A tightening member 214 is commonly connected between the two wires 216, so that the wires 216 are simultaneously tightened by the tightening member 214, changing the relative distance between the corresponding movable plate and the tightening member 214. And, the two movable plates move synchronously and move oppositely, so that the length conversion process of the length conversion mechanism 21 is quicker, and the expected value can be reached more quickly.
Referring to fig. 7, 8 and 9, the tightening member 214 includes a rotating shaft 2143, and the two steel wires 216 are fixedly connected to the rotating shaft 2143, so that the length of the steel wires 216 between the adjusting plate 217 and the tightening member 214 can be reduced by rotating the rotating shaft 2143, thereby achieving the purpose of reducing the distance between the adjusting plate 217 and the tightening member 214.
To facilitate rotation of the shaft 2143, a rotatable member 2142 is provided at a front end of the shaft 2143. Specifically, the rotating member 2142 may have various structures, and the rotating member 2142 used in the present application is a common wrench hole, and in practice, a user can rotate the rotating shaft 2143 by matching a labor-saving wrench with the wrench hole.
In order to ensure that the steel wire rope 216 can be always in a proper position without affecting other components of the application, two limiting rings 2141 are coaxially and fixedly connected to the rotating shaft 2143, and the positions of the two steel wire ropes 216 can be limited by the limiting rings 2141.
In order to ensure that the rotating shaft 2143 can be installed, the installation frame 213 is detachably connected to the inner card of the conversion unit 211, and the rotating shaft 2143 is rotatably connected to the installation frame 213. Specifically, the mounting frame 213 may be detachably coupled to the transforming unit 211 by means of screws and bolt holes.
In order to ensure that the rotation shaft 2143 does not lose rotation force during use, the distance between the two adjusting plates 217 is increased, and the anti-back member 215 is disposed on the rotation shaft 2143, so that the rotation shaft 2143 can only rotate in a unidirectional direction in a normal state, that is, the rotation shaft 2143 can only rotate in a direction of increasing the number of windings of the steel wire rope 216 thereon.
The anti-back-out member 215 includes a ratchet 2151 fixedly connected to the shaft 2143, and the ratchet 2151 moves synchronously with the shaft 2143.
The ratchet 2151 is provided with a pawl 2152 on the upper side, and the ratchet 2151 can be limited by the pawl 2152 so that the ratchet 2151 can only rotate in one direction.
The middle position of the pawl 2152 is rotatably connected with the mounting frame 213, one end of the pawl 2152 is clamped into the teeth of the ratchet 2151, and the underside of the other end of the pawl 2152 is provided with a compression spring II2153.
The other axial end of the compression spring II2153 is fixedly connected with the mounting frame 213, so that the pawl 2152 can be clamped into the teeth of the ratchet 2151 to limit the pawl in a normal state through the lever principle, and the limiting effect of the pawl 2152 on the ratchet 2151 can be relieved when a user presses the pawl 2152 to be far away from one end of the ratchet 2151.
Referring to fig. 12 and 13, the collision mechanism 1 includes a mounting plate 11, and one end of the mounting plate 11 away from the energy absorbing component 2 is an arc surface, so as to improve the protection effect on the collision vehicle and avoid further damage to the vehicle.
The inner side of the mounting plate 11 is provided with a pressure plate 13, and the pressure plate 13 is abutted with the adjacent energy absorption component 2 so as to complete the force transmission process.
In order to ensure that the pressure plate 13 can well complete the transmission of the impact force, it is further ensured that the impact force only causes the energy absorbing component 2 to do linear motion without stroke conflict with the corrugated plate 4. The pressure plate 13 is of a wave-shaped structure, the wave crest number of the pressure plate 13 is consistent with the number of the energy absorbing units 24 in the single energy absorbing component 2, and the wave crest of the pressure plate 13 is abutted against the corresponding movable plate.
Furthermore, in order to ensure that the pressure plate 13 can be conveniently replaced after being deformed, the upper side of the horizontal end of the mounting plate 11 is fixedly connected with a positioning plate 14, the positioning plate 14 is provided with a positioning groove, and the pressure plate 13 is inserted into the positioning groove, so that the pressure plate 13 can be conveniently replaced.

In particular, the energy absorbing material may be sand.
Referring to fig. 11, it should be emphasized that, in the energy absorbing component 2 of the present application, since the structure of the transforming unit 211 is identical to that of the energy absorbing unit 24, the difference is that the transforming unit 211 is provided with a mounting groove 212 for the steel wire rope 216, and a bolt hole is provided for the bolt, so that the transforming unit 211 can replace the energy absorbing unit 24, and in practice, the replaceability of the present application can be further improved.
