Description

Technical Field

[0001] The present application relates to the technical field of crash pads with warning devices, and in particular to crash pads with a control system and a control method thereof. Background Art

[0002] At present, during road construction, in order to reduce the impact on vehicle traffic, part of the road in the same direction is generally closed, and vehicles continue to pass through the closed road. Due to the existence of passing vehicles, for safety reasons, a vehicle with a rear-end anti-collision pad installed needs to be placed in the construction area. The anti-collision pad can buffer and absorb energy. If a rear-end collision occurs, a buffer area can be constructed between the vehicle and the construction area. The energy of the impact is absorbed by the deformation of the mechanical structure, thereby minimizing the probability of collision of the protected personnel and equipment, and improving safety during construction.

[0003] The existing crash pads have a certain length. If the crash pads are longer along the length of the road, although the cushioning effect can be improved when hit by a faster vehicle, when a slower vehicle realizes that it is about to hit the crash pad and changes lanes, the longer crash pads will greatly reduce the space for the vehicle to change lanes, making it easy for the vehicle to collide with the crash pad, reducing the safety during construction. In addition, the warning effect of the crash pads is poor, making it difficult for the vehicle to be discovered, thereby reducing the safety during construction. Summary of the invention

[0004] In order to improve safety during construction, the present application provides an anti-collision pad with a control system and a control method thereof.

[0005] In the first aspect, the crash pad with a control system provided by the present application adopts the following technical solution: The anti-collision pad with a control system includes a mobile frame for slidingly setting on a vehicle body, a driving component, an alarm mechanism, and an anti-collision mechanism. The driving component is used to drive the mobile frame to move, and the alarm mechanism includes: A detection component, used for detecting the speed of the vehicle and electrically connected to the driving assembly; A warning component, which is arranged on a mobile frame and is used to display the position to an oncoming vehicle and project a warning message onto the road on the side of the oncoming vehicle; The anti-collision mechanism is arranged on the mobile frame and cushions the vehicle under the action of elastic force. The anti-collision mechanism can also rotate under the impact of the vehicle, so that the vehicle moves toward the side of the unclosed road under the action of rotation and elastic force, and the anti-collision mechanism is separated from the vehicle and then rotates back to its original position.

[0006] By adopting the above technical solution, when the warning component is activated, a visible warning message will be projected onto the ground on the oncoming vehicle side, enabling the driver to learn in advance that the lane ahead of the vehicle is under construction and quickly change the vehicle to an unclosed lane. Especially in foggy weather or other situations with poor visibility, the warning message on the road can enable the vehicle to learn the situation ahead as soon as possible and change lanes in advance to avoid, thus greatly reducing the risk of hitting the anti-collision mechanism or even the construction area and improving the safety during construction.

[0007] Meanwhile, the detection component is used to detect the speed of the vehicle, and the driving component drives the moving frame and the anti-collision mechanism to move according to the vehicle speed. When the vehicle speed is relatively fast, the moving frame and the anti-collision mechanism extend, increasing the distance between the collision point and the construction area and reducing the impact damage to the construction area. When the vehicle speed is relatively slow, the moving frame and the anti-collision mechanism retract, reducing the outward extension length of the anti-collision mechanism, providing more space for the vehicle to change to other lanes when it needs to, and reducing the risk of collision due to insufficient space, thus reducing the safety during construction.

[0008] Furthermore, after the vehicle collides with the anti-collision mechanism, the anti-collision mechanism rotates under the impact. Due to the rotation effect, the direct impact force of the vehicle on the anti-collision mechanism will be greatly reduced. The anti-collision mechanism can rebound under the elastic force, and the elastic force can push the vehicle to an unclosed road on one side. Compared with a direct impact, this design can greatly reduce the risk of the vehicle crashing into the construction area and vehicle damage, and also reduce the damage caused by a direct impact, further improving the safety during construction and of the vehicle.

[0009] Optionally, the warning component includes: A height warning light and an infrared reflection component, which are arranged on the vehicle body and used to warn the oncoming vehicle by indicating the position; Multiple projection components, which are used to project multiple visible warning messages arranged along the road length direction onto the road surface on the oncoming vehicle side.

[0010] By adopting the above technical solution, the height warning light and the infrared reflection component are used to enable the driver to know the position of the construction area in advance. However, in foggy weather or other situations with poor visibility, it is difficult for the driver to notice. Therefore, multiple projection components project multiple warning messages along the road length on the road surface to show the position of the construction area to the oncoming vehicle. At the same time, the individual projection components can also be set with different parameters according to needs, so that the warning messages farther from the vehicle body can also be clearly seen by the driver, thus greatly improving the warning effect on the driver, enabling the vehicle to change lanes and avoid in advance, and further improving the safety during construction.

[0011] Optionally, the projection member includes a first projection lamp and a plurality of second projection lamps spaced vertically. The warning messages projected by the first projection lamp and the plurality of second projection lamps on the ground gradually increase in distance from the vehicle body. The second projection lamps are rotatably mounted on the vehicle body, and adjacent second projection lamps are connected by a synchronization component. A driving member for driving one of the second projection lamps to rotate is provided on the vehicle body. After the driving member is started, it drives the plurality of second projection lamps to rotate through the synchronization component and is used to adjust the angle between the first projection lamp and the adjacent second projection lamp and the angle between adjacent second projection lamps and make the two angles consistent.

[0012] By adopting the above technical solution, the first projection lamp is used to project a warning message on the road surface closest to the vehicle body side, and the plurality of second projection lamps project warning messages on the road surface in sequence. However, the weather changes. When the visibility is sufficient, it is necessary to remind the driver multiple times at shorter intervals so that the driver can quickly understand the construction situation ahead and change lanes and avoid as soon as possible. However, when the visibility is insufficient, especially in foggy weather, etc., the warning message needs to be farther from the construction area, and the earlier the reminder is achieved, the better, so that the driver can understand the construction area situation earlier. Therefore, the position of the warning message needs to change in real time according to the weather change, so as to further improve the warning situation and thus improve the safety during construction.

[0013] The driving member drives one of the second projection lamps to rotate, and the second projection lamp drives another second projection lamp to rotate synchronously through the synchronization component, and so on, to realize the rotation of the plurality of second projection lamps, and make the angle between the first projection lamp and the adjacent second projection lamp and the angle between adjacent second projection lamps consistent, so as to adjust the position of the warning messages projected by the first projection lamp and the plurality of second projection lamps, and make the distance between adjacent warning messages consistent, so as to adjust the distribution position of the warning messages according to the weather conditions, so as to achieve a better warning effect and improve the safety during construction.

[0014] Optionally, the synchronization component includes: A first gear and a second gear, which are arranged on adjacent second projection lamps and the number of teeth of the first gear is greater than that of the second gear. The second projection lamp connected to the first gear is located on the side closer to the first projection lamp than the second projection lamp connected to the second gear; An intermediate gear, which is rotatably mounted on the vehicle body and is located between the first gear and the second gear and meshes with both of them. The number of teeth of the intermediate gear is less than that of the first gear and greater than that of the second gear.

[0015] By adopting the above technical solution, the rotation of the first gear drives the rotation of the middle gear, and the rotation of the middle gear drives the rotation of the second gear, so that two adjacent projection lamps can rotate at the same time, and the number of teeth on the first gear is greater than the number of teeth on the second gear. Even if the second projection lamp that is farther away from the first projection lamp has a greater rotation angle, the angle between the first projection lamp and the adjacent second projection lamp and the angle between the two adjacent second projection lamps remain consistent.

[0016] Optionally, the anti-collision mechanism includes: An anti-collision frame is rotatably arranged on a movable frame; An anti-collision component is arranged on the anti-collision frame and has elasticity and is used to cushion the vehicle; The adjusting assembly is arranged on the mobile frame and connected to the anti-collision frame. The anti-collision assembly drives the anti-collision frame to rotate after being impacted by the vehicle and causes the vehicle to move toward the unclosed road under the action of the rotation of the anti-collision frame and the elastic force of the anti-collision assembly. The anti-collision assembly rotates back to its original position under the action of the elastic force of the adjusting assembly after the vehicle is detached.

[0017] By adopting the above technical scheme, when a vehicle collides with the anti-collision component, the anti-collision component first cushions the impact of the vehicle to reduce the impact damage, and the anti-collision frame rotates after receiving the impact force of the anti-collision component, and the rotation of the anti-collision frame can divide the impact force of the vehicle into forces in multiple directions, thereby reducing the impact force on the anti-collision component, and the anti-collision component can move back under the action of elastic force, and the movement of the anti-collision component back can generate a thrust on the vehicle in the direction of the unclosed road, so that the vehicle can be separated from the anti-collision component as soon as possible and enter the unclosed road, which greatly reduces the risk of the vehicle entering the construction area and the degree of damage to the vehicle. After the vehicle is separated, the anti-collision frame can rotate to its original position under the action of the elastic force of the adjustment component to prepare for the continued impact of subsequent vehicles, thereby improving the safety of construction and the vehicle.

[0018] Optionally, the anti-collision frame includes a rotating part rotatably mounted on the mobile frame through a rotating shaft and a mobile part slidably arranged on the rotating part, and a fixed plate is arranged on the rotating part. The anti-collision assembly includes: The anti-collision pad body is arranged on the end of the moving part away from the rotating part. The anti-collision frame is arranged on the mobile frame and has a plurality of sandbags for anti-collision placed inside. The mobile frame, the anti-collision pad body, the rotating part and the moving part cooperate to form an avoidance cavity for avoiding the rotation of the anti-collision frame; An anti-collision spring is connected to the anti-collision pad body and the fixing plate and cooperates with the anti-collision pad body to buffer and prevent collision; The blocking block is arranged on the moving frame and abuts against the rotating part so that the anti-collision frame can only rotate toward the side of the unclosed road.

[0019] By adopting the above technical solution, the main body of the anti-collision pad can first buffer the impact force of the vehicle, and then the main body of the anti-collision pad pushes the moving part to move, thereby pushing and squeezing the anti-collision spring and the adjusting component to further buffer. Under the action of the main body of the anti-collision pad and the moving part, the rotating part is pushed to rotate. At the same time, the impact force of the vehicle will continue to act on the anti-collision frame and the sandbag. The sandbag can provide gravity and achieve buffering, so as to better buffer the impact force of the vehicle.

[0020] The impact force will cause the anti-collision frame to be out of balance. Due to the setting of the blocking block, the rotating part is driven to rotate towards the unclosed road side. Especially when the impact point of the vehicle and the main body of the anti-collision pad is located on the side of the rotating shaft close to the unclosed road side, the rotation effect of the rotating part is more obvious. The rotation of the rotating part also pushes the moving part and the main body of the anti-collision pad to rotate. The rotation reduces the impact force of the vehicle on the main body of the anti-collision pad and the moving part. The main body of the anti-collision pad, the anti-collision spring and the adjusting component all move back under the action of elastic force, thereby pushing the vehicle to move away from the vehicle body, that is, the vehicle moves towards the unclosed road surface. Moreover, the design of the anti-collision frame and the sandbag can improve the buffering effect and also block the vehicle from moving towards the vehicle body, so that the vehicle moves to the unclosed lane, thus improving the safety during construction and for the vehicle.

[0021] Optionally, the adjusting component includes: The first spring and the second spring are arranged at both ends on the moving frame and on both sides of the rotating shaft and are in an inclined state. The other ends of the first spring and the second spring are connected to the fixed disk and are used to maintain the stable state of the rotating part. After the main body of the anti-collision pad is separated from the vehicle, the first spring and the second spring drive the anti-collision frame and the main body of the anti-collision pad to rotate back to the original position; There are two rod bodies one and two, which are respectively arranged at the first spring and the second spring. One end of the rod body one and the rod body two are slidably connected, and the other ends are respectively rotatably connected to the moving frame and the fixed disk. The first spring and the second spring are both sleeved on the rod body one and the rod body two.

[0022] By adopting the above technical solution, when the vehicle impacts, the rotating part rotates, and the rotation of the rotating part generates a force on the first spring and the second spring. The first spring and the second spring first buffer the impact force of the vehicle. Secondly, after the vehicle separates from the main body of the anti-collision pad, the rotating part can rotate back to its original position under the elastic force of the first spring and the second spring, and then continue to buffer the next vehicle. Thus, it can directly buffer the impact force of the vehicle, and at the same time, it can also make the anti-collision frame rotate and then return to its original position, so as to achieve the above two different effects, improve the safety during construction. The first rod and the second rod move relative to each other when the rotating part rotates, and at the same time, they can guide the deformation of the first spring and the second spring, making the deformation of the first spring and the second spring more stable, reducing the risk of the spring protruding outward and being damaged when receiving a force, especially a pressure, and improving the stability of the anti-collision mechanism during operation, further improving the safety during construction.

[0023] Optionally, the second spring is located on the side of the first spring close to the unclosed road and its elastic force is less than that of the first spring.

[0024] By adopting the above technical solution, when the vehicle impacts the main body of the anti-collision pad, since the main body of the anti-collision pad can only move along the direction close to or away from the moving frame, the force on both sides of the rotating part is unbalanced, making the main body of the anti-collision pad and the rotating part more likely to rotate towards the unclosed road side, thus further improving the effect of pushing the vehicle to the unclosed road side and improving the safety during construction.

[0025] Optionally, the driving assembly includes: A first moving part for driving the moving frame to move; A first toothed bar provided on the moving frame; A second toothed bar slidably provided on the vehicle body and meshing with the first toothed bar for positioning; A second moving part for driving the second toothed bar to move.

[0026] By adopting the above technical solution, the driving part drives the second toothed bar to disengage from the first toothed bar, and then the first moving part drives the moving frame, the first toothed bar and the anti-collision mechanism to move. After the movement is completed, the second moving part drives the second toothed bar to approach and mesh with the first toothed bar, thereby realizing the positioning of the position of the moving frame, so as to realize the adjustment of the position of the moving frame. Moreover, through the cooperation of the second moving part itself, the first moving part, the first toothed bar and the second toothed bar for positioning in two mutually perpendicular directions, compared with a single direction, the positioning effect of the moving frame and the anti-collision mechanism is improved, and the safety during construction is further improved.

[0027] In a second aspect, the control method of the anti-collision pad provided by the present application adopts the following technical solution: The anti-collision pad control method includes the following steps: High warning lights and infrared reflectors are used to indicate the location of the construction area. At the same time, multiple projection components are activated to project multiple warning messages arranged along the road on the oncoming vehicle road, so as to cooperate with indicating the location of the construction area and to warn vehicles. The detection component is used to detect the speed of oncoming vehicles. The driving component starts according to the vehicle speed to adjust the length of the anti-collision mechanism, so that the length of the anti-collision mechanism is adapted to the oncoming vehicle speed; the anti-collision mechanism is used to start and cooperate to reduce the impact damage of the vehicle on the construction area.

[0028] By adopting the above technical solution, high warning lights and infrared reflectors are used to indicate the location of the construction area. At the same time, multiple projection components are activated to project multiple warning messages arranged along the road on the oncoming vehicle road, so as to cooperate with indicating the location of the construction area and to warn vehicles. The detection component is used to detect the speed of oncoming vehicles. The driving component starts according to the vehicle speed to adjust the length of the anti-collision mechanism, so that the length of the anti-collision mechanism is adapted to the oncoming vehicle speed; the anti-collision mechanism is used to start and cooperate to reduce the impact damage of the vehicle on the construction area.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the detection component and the driving component, when the vehicle speed is relatively fast, the anti-collision mechanism is extended, the distance between the collision point and the construction area is extended, and the impact damage to the construction area is reduced. When the vehicle speed is relatively slow, the moving frame and the anti-collision mechanism retract, reducing the outward extension length of the anti-collision mechanism, making the space larger when the vehicle needs to change to other lanes after discovery, and reducing the risk of collision due to insufficient space, improving the safety during construction.

[0030] 2. By the warning component projecting warning messages on the road in advance, the vehicle can predict the location of the construction area in advance, enabling the vehicle to change lanes and avoid in advance. Especially in situations with insufficient visibility such as fog, the warning messages on the road can let the driver know the situation earlier, thus greatly reducing the risk of the vehicle hitting the construction area and improving the safety during construction.

[0031] 3. After the vehicle collides with the anti-collision mechanism, the anti-collision mechanism rotates under the impact. Due to the rotation effect, the direct impact force of the vehicle on the anti-collision mechanism will be greatly reduced. The anti-collision mechanism can rebound under the elastic force, and the elastic force can push the vehicle to the unclosed road on one side. This design can greatly reduce the risk of the vehicle crashing into the construction area and vehicle damage, further improving the safety during construction and of the vehicle.

Detailed implementation manners

[0034] The following further elaborates on this application in detail.

[0035] The embodiment of this application discloses an anti-collision cushion with a control system.

[0036] Refer to Figure 1 and Figure 2, the anti-collision pad with a control system includes a moving frame 1 horizontally slidably arranged on the vehicle body 15, and also includes a driving component 2, an alarm mechanism 3, and an anti-collision mechanism 6. The driving component 2 is used to drive the moving frame 1 to move. The alarm mechanism 3 is used to detect the vehicle speed and is electrically connected to the driving component 2. The anti-collision mechanism 6 is arranged on the moving frame 1 and is used to buffer and prevent collision with the vehicle under the action of elastic force and is electrically connected to the detection component 31. The driving component 2 drives the moving frame 1 and the anti-collision mechanism 6 to move according to the vehicle speed, so that the length of the anti-collision mechanism 6 extends or shortens, that is, approaches or moves away from the vehicle, so as to adapt to different vehicle speeds. At the same time, the alarm mechanism 3 can also project a warning message on the road surface, thereby pre-reminding the driver to understand the situation of the construction area and change lanes in advance to avoid. The anti-collision mechanism 6 can also rotate under the impact of the vehicle, so that the vehicle moves toward the unclosed road side under the action of rotation and elastic force. After the vehicle separates from the anti-collision mechanism 6, the anti-collision mechanism 6 rotates back to its original position under the action of elastic force.

[0037] The sliding direction of the moving frame 1 is parallel to the traveling direction of the vehicle body 15 along the road. The moving frame 1 is located on the side close to the ground, so that the anti-collision mechanism 6 is used to buffer the vehicle, reducing the risk of vehicle damage caused by the vehicle drilling under the vehicle.

[0038] Refer to Figure 2 and Figure 3 , the driving component 2 includes a first moving part 21, a first toothed bar 22, a second toothed bar 23, and a second moving part 24. The first moving part 21 and the second moving part 24 can be electric push rods. The first moving part 21 is fixedly installed on the vehicle body 15, and the piston rod of the first moving part 21 is connected to the side wall of the moving frame 1. The first toothed bar 22 is fixedly installed on the side wall of the moving frame 1 and is arranged along the sliding direction of the moving frame 1. The second toothed bar 23 is slidably installed on the vehicle body 15, and the sliding direction is perpendicular to the sliding direction of the moving frame 1. The second moving part 24 is fixedly installed on the vehicle body 15, and the piston rod is fixedly connected to the second toothed bar 23. The second moving part 24 is used to drive the second toothed bar 23 to mesh with the first toothed bar 22, so as to position the position of the moving frame 1. When the moving frame 1 needs to move, the second moving part 24 drives the second toothed bar 23 to disengage from the first toothed bar 22, and the first moving part 21 can drive the moving frame 1 to move.

[0039] Refer to Figure 1 , Figure 3 and Figure 4, the alarm mechanism 3 includes a detection component 31 and a warning component 32. A vertical gantry 11 is fixedly installed on the vehicle body 15 and on the side close to the anti-collision mechanism 6. The detection component 31 is fixedly installed on the top of the gantry 11. The detection component 31 is a speed detector and is used to detect the speed of the vehicle. A control box for controlling the start and stop of the first moving component 21 and the second moving component 24 is fixedly installed on the vehicle body 15. The detection component 31 is used to transmit the detected vehicle speed data to the control box, and the control box controls the start and stop of the first moving component 21 and the second moving component 24 according to the vehicle speed, so as to control the extended length of the anti-collision mechanism 6.

[0040] The detection component 31 is used to detect the vehicle speed. Once it is monitored that the oncoming vehicle speed reaches a certain threshold (for example, 60 km / h), the control box immediately starts to control the first moving component 21 and the second moving component 24 to start, so that the anti-collision mechanism 6 extends. For example, the anti-collision mechanism 6 extends from the initial contracted state, that is, 50% of the total length, to 75% of the length; when the speed of the vehicle behind continues to increase to 120 km / h and above, the anti-collision mechanism 6 extends completely to 100% of the length, thereby increasing the buffer space in the construction area, reducing the impact damage of the vehicle on the construction area, and at the same time, the above data can be adjusted according to needs to better fit the actual situation; if the detection component 31 detects that the vehicle speed is lower than a certain threshold, the anti-collision mechanism 6 shortens, leaving a large space in front of the anti-collision mechanism 6 for the vehicle to change lanes, further reducing the impact damage of the vehicle on the construction area and improving the safety during construction.

[0041] Refer to Figure 1 , Figure 4 , the warning component 32 is arranged on the moving frame 1 and is used to display the position to the vehicle and project warning messages on the road on the oncoming vehicle side. The warning component 32 includes a height warning light 33 and an infrared reflecting member 34, and a plurality of projection members 35. The height warning light 33 and the infrared reflecting member 34 are fixedly installed on the side wall of the gantry 11 close to the oncoming vehicle and are used to display the position to the vehicle for warning. A through hole for the height warning light 33 to pass through is opened on the infrared reflecting member 34 at the position of the height warning light 33. The height warning light 33 and the infrared reflecting member 34 are structures in the prior art and will not be elaborated here.

[0042] The plurality of projection members 35 are used to project a plurality of visible warning messages on the road surface on the oncoming vehicle side. The plurality of warning messages are arranged along the road length direction and are used to warn the vehicle, so that the vehicle can pre-understand the situation of the construction area ahead. Especially in weather such as heavy fog, the light projected by the projection member 35 can penetrate the heavy fog and be projected on the ground, so that the driver can know the position of the construction area in advance and change lanes in advance to avoid, improving the safety during construction and of the vehicle.

[0043] Refer to Figure 4 and Figure 5, a plurality of projection members 35 include a first projection lamp 36 and a plurality of second projection lamps 37 spaced vertically. The first projection lamp 36 is located at the lowest position and fixedly installed on the gantry 11, such that the warning words projected on the ground by the first projection lamp 36 and the plurality of second projection lamps 37 are at an increasing distance from the vehicle body 15. The plurality of second projection lamps 37 are rotatably installed on the gantry 11 through a rotating shaft 38, and a synchronous component 5 is connected between the rotating shafts 38 on two adjacent second projection lamps 37. A driving member 39 for driving one of the second projection lamps 37 to rotate is provided on the gantry 11. The driving member 39 is a driving motor, and the output shaft of the driving member 39 is connected to the rotating shaft 38 at the lowest position. After the driving member 39 is started, it drives the plurality of second projection lamps 37 to rotate through the synchronous component 5, and is used to adjust the angle between the first projection lamp 36 and the adjacent second projection lamp 37 and the angle between two adjacent second projection lamps 37 to make the two angles the same.

[0044] The synchronous component 5 includes a first gear 51, a second gear 52, and an intermediate gear 53. The first gear 51 and the second gear 52 are respectively key-connected to two rotating shafts 38, and the number of teeth of the first gear 51 is greater than that of the second gear 52. The second projection lamp 37 connected to the first gear 51 is located on the side closer to the first projection lamp 36 than the second projection lamp 37 connected to the second gear 52, that is, the first gear 51 is located below the second gear 52. The intermediate gear 53 is rotatably installed on the gantry 11, and the intermediate gear 53 is located between the first gear 51 and the second gear 52 and meshes with both of them. At the same time, the number of teeth of the intermediate gear 53 is greater than that of the second gear 52 and less than that of the first gear 51, and the number of teeth of the first gear 51, the second gear 52, and the intermediate gear 53 are designed according to actual needs, as long as the requirements can be met.

[0045] The driving member 39 drives the rotating shaft 38 to rotate. The rotating shaft 38 rotates to drive the first gear 51 and the second projection lamp 37 to rotate. The first gear 51 rotates to drive the intermediate gear 53 to rotate. The intermediate gear 53 rotates to drive the second gear 52 to rotate. The second gear 52 drives the rotating shaft 38 and the second projection lamp 37 connected to it, so as to realize the rotation of two adjacent second projection lamps 37, and make the angle between the first projection lamp 36 and the adjacent second projection lamp 37 and the angle between two adjacent second projection lamps 37 keep consistent.

[0046] Refer to Figure 1 , Figure 6, a rotating seat 4 is horizontally rotatably installed at one end of the moving frame 1 away from the vehicle body 15. The moving frame 1 is rotatably installed with a lifting member 41 that rotates with the rotating seat 4. The lifting member 41 can be an electric push rod. The anti-collision mechanism 6 is arranged on the rotating seat 4. The lifting member 41 is used to drive the anti-collision mechanism 6 to rotate upward away from the ground, so as to facilitate the vehicle body 15 to transport the anti-collision mechanism 6. When it is necessary to prevent collisions in the construction area, after the vehicle body 15 transports the anti-collision mechanism 6 to the position, the lifting member 41 drives the anti-collision mechanism 6 to be placed on the ground, so as to facilitate the realization of anti-collision in the construction area.

[0047] Refer to Figure 6 , Figure 7 , the anti-collision mechanism 6 includes an anti-collision frame 61, an anti-collision component 7 and an adjustment component 8. The anti-collision frame 61 includes a rotating part 62 and a moving part 63. A plurality of rotating parts 62 and moving parts 63 are arranged at intervals on the same horizontal plane, and two rotating parts 62 and moving parts 63 are arranged vertically at intervals on the same vertical plane.

[0048] The rotating part 62 includes an inclined section 621 and a horizontal section 622. A plurality of inclined sections 621 on the same horizontal plane are all rotatably installed on the side wall of the rotating seat 4 away from the moving frame 1 through a vertical rotating shaft 64. The other end of the inclined section 621 is inclined away from the rotating shaft 64 and the rotating seat 4. The horizontal section 622 is integrally arranged on the inclined section 621 and is arranged parallel to the sliding direction of the moving frame 1. A fixed disk 623 is fixedly installed at the connection between the inclined section 621 and the horizontal section 622. The moving part 63 slides through the end of the horizontal section 622 away from the inclined section 621 and the rotating seat 4, and the sliding direction of the moving part 63 is parallel to the sliding direction of the moving frame 1. The anti-collision component 7 is arranged on the anti-collision frame 61 and has elasticity, and is used to buffer the impact of the vehicle.

[0049] The anti-collision component 7 includes an anti-collision pad main body 71, an anti-collision frame 72, an anti-collision spring 73, and a blocking block 74. The anti-collision pad main body 71 is fixedly installed on one ends of a plurality of moving parts 63 away from the rotating part 62. The anti-collision pad main body 71 is an elastic plate-like structure extending along the direction perpendicular to the sliding direction of the moving part 63. A clearance cavity 65 is formed by the cooperation between the moving frame 1, the two vertically arranged rotating parts 62 and the two moving parts 63 and the anti-collision pad main body 71. The anti-collision frame 72 is fixedly installed on the side wall of the moving frame 1 and is located in the clearance cavity 65. The upper surface of the anti-collision frame 72 is in an open state, and a plurality of sandbags 75 are placed in the anti-collision frame 72. The plurality of sandbags 75 fill and position the inside of the anti-collision frame 72 to achieve weight and reduce the impact force.

[0050] On the side wall of the anti-collision pad main body 71 close to the rotating seat 4, a deformable protective sleeve 12 fixedly connected to the side wall of the rotating seat 4 is fixedly installed. An installation opening 13 is formed on the upper surface of the protective sleeve 12. A deformable installation plate 14 is installed in the installation opening 13. The installation plate 14 seals the installation opening 13. Opening the installation opening 13 enables sandbags 75 to be placed into or taken out of the anti-collision frame 72. The deformable protective sleeve 12 and installation plate 14 facilitate avoidance during the rotation of the anti-collision pad main body 71.

[0051] A plurality of anti-collision springs 73 are provided and are correspondingly arranged with a plurality of moving parts 63. The protective springs are sleeved on the moving parts 63 and the horizontal section 622, and both ends are fixedly connected to the fixed disk 623 and the anti-collision pad main body 71 respectively. Two blocking blocks 74 are vertically arranged at intervals and are correspondingly arranged with the two rotating parts 62. The blocking blocks 74 are detachably installed on the side wall of the rotating seat 4 and abut against the inclined section 621 for positioning, so that the rotation direction of the rotating part 62 can be adjusted, and the rotating part 62 can only rotate towards the side close to the unclosed road.

[0052] The adjusting assembly 8 is arranged on the rotating seat 4 and is connected to the anti-collision frame 61. The adjusting assembly 8 includes a first spring 81, a second spring 82, a rod body one 83 and a rod body two 84. One ends of the first spring 81 and the second spring 82 are respectively fixedly installed on the side walls of the rotating seat 4 located on both sides of the rotating shaft 64 and the anti-collision frame 61. The other ends of the first spring 81 and the second spring 82 face the anti-collision pad main body 71 and are arranged towards the two fixed disks 623 at the corresponding positions and are fixedly connected to the fixed disks 623. That is, the distance between the two ends of the first spring 81 and the second spring 82 close to the rotating seat 4 is greater than the distance between the two ends of the first spring 81 and the second spring 82 close to the anti-collision pad main body 71; the second spring 82 is located on the side of the first spring 81 close to the unclosed road, that is, the second spring 82 is closer to the unclosed road.

[0053] The elastic force of the second spring 82 is the same as that of the first spring 81, or the elastic force of the second spring 82 is less than that of the first spring 81, so that the second spring 82 is more easily deformed, and the anti-collision pad main body 71 is more easily rotated towards the unclosed road. At the same time, the elastic force difference between the second spring 82 and the first spring 81 is less than the elastic force of the protective sleeve 12, so that the anti-collision pad main body 71 can maintain a stable state under the action of the protective sleeve 12 in the initial state.

[0054] At the same time, the first spring 81 is provided at two of the inclined sections 621 arranged vertically, and the second spring 82 is provided at the other two inclined sections 621; the first spring 81 and the second spring 82 are provided with a rod body 1 83 and a rod body 2 84, and the rod body 1 83 and the rod body 2 84 are slidably sleeved on each other and the two ends away from each other are respectively rotatably connected with the side wall of the rotating seat 4 and the fixed plate 623 away from the side wall of the anti-collision spring 73, the diameter of the rod body 1 83 and the rod body 2 84 is smaller than the inner diameter of the first spring 81 and the second spring 82, and at the same time, the rod body 1 83 and the rod body 2 84 are slidably connected to each other, which can guide the first spring 81 and the second spring 82 when they are deformed, so that the two are deformed according to a predetermined path, thereby increasing the deformation force of the first spring 81 and the second spring 82 after deformation, and reducing the risk of damage to the two.

[0055] When a vehicle collides with the crash pad body 71, the crash pad body 71 first buffers the impact force of the vehicle, and then the crash pad body 71 squeezes the multiple crash springs 73, the multiple first springs 81 and the multiple second springs 82, so as to buffer the crash pad body 71. At the same time, the impact force will also cause the rotating part 62 and the moving part 63 to rotate toward the side of the unclosed road. The rotation reduces the impact force of the vehicle. The crash pad body 71, under the action of itself, the crash springs 73, the first springs 81 and the second springs 82, pushes the vehicle toward the unclosed road, so that the vehicle moves to the unclosed road and separates from the crash pad body 71.

[0056] The rotation of the anti-collision pad body 71 generates a force on the first spring 81 and the second spring 82, generates a pulling force on the first spring 81 and a pressure on the second spring 82. After the vehicle is separated from the anti-collision pad body 71, the first spring 81 and the second spring 82 push the anti-collision pad body 71 to rotate back to its original position under the action of their own elastic restoring force, thereby continuing to cushion the subsequent vehicles and improving safety during construction.

[0057] The working principle of the embodiment of the present application is as follows: The detection member 31 is used to detect the vehicle speed. When the speed of the oncoming vehicle reaches a certain threshold, the control box immediately starts to control the moving member 1 21 and the moving member 2 24 to start, so that the anti-collision mechanism 6 is extended, thereby increasing the buffer space of the construction area, thereby reducing the impact damage of the vehicle on the construction area; if the detection member 31 detects that the vehicle speed is lower than a certain threshold, the anti-collision mechanism 6 is shortened, so that the vehicle has a larger space in front of the anti-collision mechanism 6 for the vehicle to change lanes, further reducing the impact damage of the vehicle on the construction area and improving the safety during construction.

[0058] The height warning lamp 33 and the infrared reflection member 34 are used to indicate the position of the construction area to oncoming vehicles. At the same time, the driving member 39 starts to adjust the angles of a plurality of second projection lamps 37, so that a plurality of first projection lamps 36 cooperate to project a plurality of warning messages at intervals on the road of the oncoming vehicle, enabling the driver to understand the position of the construction area in advance and change lanes to avoid, thereby further reducing the risk of the vehicle hitting the construction area and improving the safety during construction.

[0059] When the vehicle hits the anti-collision pad main body 71, the anti-collision pad main body 71, a plurality of anti-collision springs 73, a plurality of first springs 81 and a plurality of second springs 82 buffer the impact force. At the same time, the impact force also causes the rotating part 62 and the moving part 63 to rotate towards the unenclosed road side, and the rotation reduces the impact force of the vehicle. The anti-collision pad main body 71, under the action of itself, the anti-collision springs 73, the first springs 81 and the second springs 82, pushes the vehicle to move towards the unenclosed road, so that the vehicle moves to the unenclosed road and detaches from the anti-collision pad main body 71. The first springs 81 and the second springs 82 push the anti-collision pad main body 71 to rotate back to its original position under the action of their own elastic restoring forces, so as to continue to buffer subsequent vehicles and improve the safety during construction.

[0060] The embodiment of the present application discloses a control method for an anti-collision pad.

[0061] Refer to Figures 1 - 3 , the control method of the anti-collision pad includes the following steps: The height warning lamp 33 and the infrared reflection member 34 are used to indicate the position of the construction area. At the same time, a plurality of projection members 35 are activated to project a plurality of warning messages arranged along the road on the oncoming vehicle road, so as to cooperate to indicate the position of the construction area and be used to warn the vehicle.

[0062] The detection member 31 is used to detect the speed of the oncoming vehicle, and the driving assembly 2 starts according to the vehicle speed to adjust the length of the anti-collision mechanism 6, so that the length of the anti-collision mechanism 6 is adapted to the speed of the oncoming vehicle; the anti-collision mechanism 6 is used to start and cooperate to reduce the impact damage of the vehicle to the construction area.

[0063] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
