[0076] like Figure 4 , Figure 8 and Fig. 9As shown, each buffer bent plate assembly 113 includes a buffer bent plate 1131, two first mounting columns 1132 and two second mounting columns 1133. The first mounting columns 1132 and the second mounting columns 1133 are mirror-imaged and arranged in pairs at the long sides of the buffer upper box 1111 to form a bent plate limiting unit. The two ends of the buffer bent plate 1131 are respectively limited in the bent plate limiting unit. The first mounting columns 1132 and the second mounting columns 1133 are specifically arranged between the box body flange and the box bottom of the buffer upper box 1111.

[0077] Furthermore, a first mounting column screw hole 11321 is provided at the lower end of the first mounting column 1132, and a first mounting column limiting hole 11322 is provided at the upper end of the first mounting column 1132; a second mounting column limiting hole 11332 is provided at the upper end of the second mounting column 1133, and a second mounting column screw hole 11331 is provided at the lower end of the second mounting column 1133.

[0101] Preferably, the rear inner buffer lower body 122, the rear inner buffer upper body 123 and the rear outer buffer body 124 are all made of elastic hard rubber products, which are conducive to absorbing impact loads and have resilience. While protecting the warning guide body component 3 from damage and the warning component 2 from working normally, it can also protect high-speed colliding vehicles from hard collisions and causing damage to people and vehicles.

[0102] However, the tail energy absorbing units are all made of rubber and are assembled components. To ensure the overall structural consistency of the tail energy absorbing units, a tail internal buffer core 125 is installed in the tail internal buffer lower body 122 in this embodiment 1.

[0103] like Fig.13As shown, the tail internal buffer core 125 is arranged inside the hollow shaft platform of the tail internal buffer lower body 122. Optionally, the tail internal buffer core 125 is a compression spring or a thin-walled steel sleeve. In this embodiment, the tail internal buffer core 125 is preferably a compression spring, which has energy absorption and damping performance that can match rubber products.

[0104] Preferably, the maximum physical diameter of the tail inner buffer core 125 is the same as the inner diameter of the rear axle platform of the tail inner buffer lower body 122 .

[0105] Preferably, in the installed position, the two ends of the tail internal buffer core 125 respectively contact the bottom of the inner cavity of the front axle platform of the tail internal buffer lower body 122 and the inner cover end surface of the tail internal buffer upper body 123.

[0106] The setting of the rear inner buffer core 125, on the one hand, plays a role in supporting the rear energy absorption unit of the elastic body to make its structure consistent, and on the other hand, further enhances the energy absorption effect of the rear buffer assembly 12 and improves the anti-collision ability of the traffic warning guide vehicle of the present invention.

[0107] When the impact load is applied from the front, the energy absorption unit at the rear, the buffer block 15, and the buffer curved plate assembly 113 absorb the energy and rebound in turn, which plays a two-way protective role on the impact body and the traffic warning guide vehicle of the present invention. When the impact load is too large, the damping generated by the energy absorption of each energy absorption component (the rear energy absorption unit, the buffer block 15, and the buffer curved plate assembly 113) still cannot rebound to the original position and is compressed. The buffer support beam assembly 14 will play the role of rigid support to resist impact deformation until each energy absorption component plays its role again.

[0108] Preferably, the two rear energy absorbing units are installed in the left and right directions at 1 / 4 and 3 / 4 of the bottom of the rear buffer box 121.

[0109] The traffic warning guide vehicle may be impacted not only from the rear but also from the side. Therefore, in the embodiment 1, a side buffer assembly 13 is provided on the left and right sides of the buffer box assembly 11. The two side buffer assemblies 13 are mirror-imaged.

[0110] Combination Figure 7 , Fig.15 and Fig.16 As shown, the side buffer assembly 13 includes a side housing unit 131, a side bottom plate unit 132 and a side buffer body 133. The side bottom plate unit 132 is connected to the outer wall surface of the side of the buffer box assembly 11, the side housing unit 131 is connected to the rear buffer box 121 and the buffer vehicle body connecting plate 16, and the side buffer body 133 is arranged between the side housing unit 131 and the side bottom plate unit 132.

[0111] like Fig.15As shown, the side housing unit 131 includes a side housing 1311 and a side housing limiting ring 1312 .

[0112] The side shell 1311 is a pair of open box structures with inclined surfaces, and a side shell mounting portion extends from the inclined surface near the opening, and the side shell mounting portion is provided with side shell and tail shell mounting holes 13111; the side shell and tail shell mounting holes 13111 are designed to match the mounting holes at corresponding positions on the rear buffer box 121 and the buffer body connecting plate 16, and are connected by fasteners.

[0113] A side shell limiting ring 1312 is provided in the middle of the inner bottom of the side shell 1311. Specifically, it is welded. Preferably, the side shell limiting ring 1312 is a circular ring structure, and the inner side wall of the side shell limiting ring 1312 has an open slope, so that the installation work can still be completed when there is an error in the installation position.

[0114] like Figure 7 and Fig.16 As shown, the side bottom plate unit 132 includes a side bottom plate 1321 and a side bottom plate limiting ring 1322 .

[0115] The side bottom plate 1321 is a long steel plate with side bottom plate mounting holes 13211 respectively provided at both ends, and is centrally connected to the front side of the buffer upper box body 1111 and the rear side of the buffer upper box body 1111 provided with matching mounting holes through fasteners.

[0116] A side bottom plate limiting ring 1322 is connected to the middle of the long steel plate of the side bottom plate 1321, specifically by welding. In the installed state, the side bottom plate limiting ring 1322 is concentrically arranged with the side shell limiting ring 1312.

[0117] Preferably, the side buffer body 133 is a rubber product with a circular ring structure, and the theoretical value of the circular ring height of the side buffer body 133 is the distance from the inner box bottom of the side shell 1311 to the side bottom plate 1321 in the side installation state.

[0118] The buffer component 1 is connected to the warning guide body component 3 through a buffer body connecting plate 16 but is not limited to the buffer body connecting plate 16 .

[0119] like Fig. 20 As shown, the warning guide vehicle body component 3 includes a vehicle body 31, a vehicle body support body 32, a vehicle body warning installation part 33 and a tire 34, and also includes a spare tire 341 arranged in the tail buffer assembly 12. The vehicle body support body 32 cooperates with the tire 34 to support the entire traffic warning guide vehicle with an anti-collision energy absorption device when the embodiment 1 is independently operated on the highway. The vehicle body warning installation part 33 is used to plug and weld the warning component 2.

[0120] like Fig.19As shown, the warning component 2 includes a warning frame 21, a voice-activated warning unit 22, a display screen 23, a constant flashing warning unit, a visual unit 26, and a turn display unit 25, or any combination thereof. Preferably, the warning component 2 of this embodiment 1 includes a warning frame 21, a voice-activated warning unit 22, a display screen 23, a constant flashing warning unit, a visual unit, and a turn display unit 25.

[0121] The warning frame 21 includes a frame and a cross support frame. The lower end of the frame of the warning frame 21 has a warning mounting portion for inserting the vehicle body warning mounting portion 33 to connect the warning guide vehicle body component 3. The constant flash warning unit includes a front constant flash warning unit 241 arranged on the warning frame 21 and a rear constant flash warning unit 242 arranged outside the shell of the rear buffer box 121.

[0122] Preferably, the front constant flash warning unit 241, the display screen 23, and the turn display unit 25 are sequentially arranged on the warning frame 21 from top to bottom, and can all be remotely controlled. The rear constant flash warning unit 242 can also be remotely controlled.

[0123] The voice-controlled warning unit 22 includes a voice-controlled player, and at least two voice-controlled players are provided as a redundant configuration on the warning frame 21. The voice-controlled warning unit 22 can be remotely controlled.

[0124] The turn display unit 25 includes a plurality of lights arranged on the frame and cross support frame of the warning frame 21, which are used to form an indication of the driving direction to the rear vehicles with different combinations of indicator lights. The turn display unit 25 can be remotely controlled.

[0125] The visual unit 26 includes a camera. In this embodiment, the camera of the visual unit 26 is preferably a pan-tilt camera that can be remotely controlled.

[0126] Example 2

[0127] Embodiment 2 is a second type of traffic warning guide vehicle with an anti-collision energy absorption device.

[0128] like Figure 5 As shown, Example 2 is formed by replacing the buffer curved plate assembly 113 with a buffer damping spring unit 112 in the first traffic warning guide vehicle with an anti-collision energy absorption device of Example 1. That is, the buffer box assembly 11 includes one or more buffer box units 111 and buffer damping spring units 112 connected in sequence; one or more buffer damping spring units 112 are installed in each buffer box unit 111. In this Example 2, preferably, one buffer damping spring unit 112 is installed in each buffer box unit 111.

[0129] Specifically, the buffer damping spring unit 112 is installed at the center of the front and rear sides of the buffer upper box body 1111. The mounting holes on the buffer box unit 111 include a strip-shaped upper shell buffer damping spring sheet side mounting hole 11111 on one side wall in the front and rear directions, and an upper shell buffer damping spring sheet center mounting hole 11113 on the opposite side wall. The upper shell buffer damping spring sheet center mounting hole 11113 is arranged in the center of the two upper shell buffer damping spring sheet side mounting holes 11111.

[0130] like Fig.10 As shown, the buffer and vibration-damping spring unit 112 of Example 2 includes a buffer and vibration-damping spring leaf 1121 , a buffer and vibration-damping spring 1122 , a first buffer and vibration-damping spring connecting plate 1123 , a second buffer and vibration-damping spring connecting plate 1124 and a buffer and vibration-damping guide column 1125 .

[0131] The buffering and vibration-damping spring 1121 is a trapezoidal bent sheet structure with two outwardly extending mounting plates, which can be movably connected to the front side wall of the buffering upper box 1111 via the side mounting holes 11111 of the buffering and vibration-damping spring of the upper shell at the two mounting plates, and the middle part of the other end of the buffering and vibration-damping spring 1121 is connected to the rear side wall of the buffering upper box 1111 via the central mounting hole 11113 of the buffering and vibration-damping spring of the upper shell.

[0132] Two ends of the buffer and vibration-damping spring 1122 are fastened between the first buffer and vibration-damping spring connecting plate 1123 and the second buffer and vibration-damping spring connecting plate 1124 .

[0133] The first end of the buffer vibration reduction guide column 1125 is threaded, and is connected to a nut fixed to the outer wall of the rear side of the buffer upper box 1111 through the central mounting hole 11212 of the buffer vibration reduction spring, and locks the first connecting plate 1123 of the buffer vibration reduction spring to the inner wall of the rear side of the buffer upper box 1111. After the buffer vibration reduction guide column 1125 is connected to the buffer upper box 1111 and the first connecting plate 1123 of the buffer vibration reduction spring in this way, it passes through the buffer vibration reduction spring 1122, and the second end passes through the second connecting plate 1124 of the buffer vibration reduction spring.

[0134] Preferably, the length of the buffer and vibration-damping guide column 1125 extending out of the second connecting plate 1124 of the buffer and vibration-damping spring satisfies the comprehensive deformation height of the buffer and vibration-damping spring leaf 1121 after being compressed.

[0135] After the buffer and vibration-damping spring 1121 is subjected to an external impact load, the mounting plate part can be displaced to a limited extent within the mounting hole 11111 on the buffer and vibration-damping spring side of the upper shell of the long hole, and the angle between the two inclined surfaces of the trapezoidal bent sheet becomes larger. At the same time, the trapezoidal bent sheet itself is allowed to deform to a certain degree of arc, and the trapezoidal bent sheet absorbs energy during the deformation process to form damping; after the external impact load disappears, the trapezoidal bent sheet returns to its original position under the reaction force of the buffer and vibration-damping spring 1122.

[0136] Example 3

[0137] Embodiment 3 is a third type of traffic warning guide vehicle with an anti-collision energy absorption device.

[0138] like Figure 6 As shown, Example 3 is the first type of traffic warning guide vehicle with an anti-collision energy absorption device of Example 1. In addition to having a buffer bent plate assembly 113, it also includes the buffer damping spring unit 112 in Example 2.

[0139] Specifically, the buffer box assembly 11 includes one or more buffer box units 111, buffer damping spring units 112 and buffer bent plate assemblies 113 connected in sequence. In each buffer box unit 111, a buffer damping spring unit 112 is installed in the middle of the front and rear directions, and buffer bent plate assemblies 113 are arranged on both sides of the buffer damping spring unit 112 in a mirror-symmetrical manner.

[0140] Example 4

[0141] Embodiment 4 is a traffic warning and guidance vehicle system with an anti-collision and energy absorption device.

[0142] like Fig.21 As shown, a traffic warning and guidance vehicle system with an anti-collision and energy absorption device according to Embodiment 4 includes the traffic warning and guidance vehicle with an anti-collision and energy absorption device of any one of Embodiments 1, 2 and 3, and also includes a control terminal 100.

[0143] The control terminal 100 can control, collect data and store data on the voice-controlled warning unit 22, the display screen 23, the constant flashing warning unit, the visual unit 26 and the turn display unit 25 included in the warning component 2 through wireless remote control.

[0144] The traffic warning guide vehicle with anti-collision energy absorption device and its system of the present invention can also be applied to autonomous highway official vehicles through modification. Specifically, the warning component 2 is mounted on the body of the autonomous highway official vehicle, and the buffer component 1 is matched with the design and connected to the rear of the autonomous highway official vehicle.

[0145] The traffic warning guide vehicle with an anti-collision energy absorption device and its system of the present invention can perform multi-stage energy absorption and vibration reduction. While completing the warning task and protecting the traffic warning guide vehicle, it can reduce or alleviate the degree of casualties of personnel in the accident vehicle and damage to equipment. When the accident vehicle collides with the traffic warning guide vehicle, the anti-collision buffer device of the traffic warning guide vehicle will first accept the strong impact force deformation of the accident vehicle, and absorb the huge impact energy from the rear accident vehicle to the greatest extent, thereby achieving a safety buffer effect, maximizing the safety of construction personnel, personnel in the accident vehicle and the traffic warning guide vehicle, and effectively avoiding casualties.

[0146] The traffic warning guide vehicle with an anti-collision energy absorption device and the system thereof have wide applicability and can be popularized for use.

[0147] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art outside the technical scope disclosed by the present invention should be covered outside the protection scope of the present invention. At the same time, any equipment equipped with the present device to expand the application field and produce a complex technical effect belongs to the scope of protection of the present invention.
