Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative efforts are within the scope of protection of the present invention.

[0058] In some embodiments of the present invention, Figure 1-10 As shown, the anti-collision vehicle blocker 100 comprises a chassis 1, a direction-changing device 2, a first shock-absorbing and buffering device 3, a second shock-absorbing and buffering device 4 and a third shock-absorbing and buffering device 5; the anti-collision vehicle blocker 100 also comprises an anti-collision vehicle blocker 100 with a reinforcement plate and a simplified version of the anti-collision vehicle blocker 100;

[0060] The steel plate 11 is provided with through holes at four top corners, and screw holes are provided at the outer circles of the through holes, and the screw holes correspond to the fixing screws 121; the fixing holes 13 are provided on the steel plate 11, and ground nails or expansion screws can be installed through the fixing holes 13 to firmly fix the steel plate 11 on the ground.

[0061] The position of the hydraulic lifting device 12 corresponds to the through holes at the four corners of the steel plate 11. A universal wheel 122 is fixedly provided at the lower end of the hydraulic lifting device 12. The universal wheel 122 can pass through the through holes at the four corners of the steel plate 11. The outer ring of the hydraulic lifting device 12 is provided with a fixing screw 121. The fixing screw 121 is threadedly connected with the screw hole on the steel plate 11. Thus, the hydraulic lifting device 12 can be fixed on the steel plate 11 or removed from the steel plate 11 by the fixing screw 121. The universal wheel 122 can be extended by the hydraulic lifting device 12, so as to lift the steel plate 11.

[0062] The anti-skid rubber layer 15 is fixedly disposed on the bottom of the steel plate 11, and the bottom of the anti-skid rubber layer 15 is provided with anti-skid stripes, which can increase the friction between the anti-skid rubber layer 15 and the ground, thereby further improving the stability of the steel plate 11;

[0063] In some embodiments of the present invention, Figure 1-2 As shown, the direction-changing device 2 includes a ramp 21 and a fixing seat 22;

[0064] The slope 21 is fixedly connected to the steel plate 11, and the slope of the slope 21 corresponds to the direction of the oncoming vehicle;

[0065] The fixing seat 22 is fixedly connected to the steel plate 11, and the fixing seats 22 are evenly arranged. The number of the fixing seats 22 is determined according to the mass of the blocked vehicle, and the number of the fixing seats 22 is not less than two; the front end of the fixing seat 22 abuts against the rear end of the slope 21;

[0066] In some embodiments of the present invention, Figure 1-7 As shown, the shock absorbing and buffering device 1 3 includes an inclined baffle 31, a main shock absorber 1 32, a shock absorbing arm 1 321, a fixing groove 3211, a shock absorbing arm 2 322, a damage spring 3221, a shock absorbing arm 3 323, a shock absorbing spring 1 324, a shock absorbing spring 2 325, a main shock absorber 2 33, a sliding base 331 and a fixing groove 1 3312;

[0067] like Figure 2 As shown, the main shock absorber 32 is fixedly and evenly arranged on the upper end of the fixing column 22, and the number of the main shock absorber 32 corresponds to the number of the fixing seat 22;

[0068] like Figure 4-7 As shown, the main shock absorber 1 32 is a three-stage shock absorber, including a shock absorber arm 1 321, a fixing slot 3211, a shock absorber arm 2 322, a damaged spring 3221, a shock absorber arm 323, a shock absorber spring 1 324 and a shock absorber spring 2 325;

[0069] Specifically, Figure 4-5As shown, the shock absorbing arm 1 321 and the shock absorbing arm 2 322 are connected through the shock absorbing spring 1 324, one end of the shock absorbing spring 1 324 abuts against the bottom of the shock absorbing arm 1 321, and the other end abuts against the bottom of the shock absorbing arm 2 322; the shock absorbing arm 2 322 and the shock absorbing arm 3 323 are connected through the shock absorbing spring 2 325, one end of the shock absorbing spring 2 325 abuts against the bottom of the shock absorbing arm 2 322, and the other end abuts against the head of the shock absorbing arm 3 323;

[0070] Of course, the above is only one embodiment of the present invention. In other embodiments of the present invention, the main shock absorber 32 may also be a two-stage or multi-stage shock absorber, and the connection method between the shock absorber arms is not limited to the above two methods, and the present application does not limit this.

[0071] like Figure 4 As shown, a fixing groove 3211 is fixedly provided on the shock absorbing arm 1 321, and a baffle is installed at the bottom of the fixing groove 3211;

[0072] like Figure 7 As shown, the structure and components of the main shock absorber 2 33 are the same as those of the main shock absorber 1 32. A sliding base 331 is fixedly provided at the bottom of the main shock absorber 2 33. The shape and size of the sliding base 331 correspond to the fixing groove 3211. Thus, the main shock absorber 2 33 can be fixedly installed on the top of the main shock absorber 1 32 through the sliding base 331 and the fixing groove 3211, and the main shock absorber 2 33 can be stacked upward in sequence.

[0073] In some embodiments of the present invention, Figure 6 As shown, the damaged steel bar 3211 can be installed on the second shock absorbing arm 322, and the damaged steel bar 3211 is plugged into the second shock absorbing arm 322, so that when the second shock absorbing arm 322 is impacted and moves into the first shock absorbing base 322, the damaged steel bar 3211 is driven to hit the first shock absorbing base 321 and disconnect in sequence, thereby further absorbing and reducing the impact kinetic energy received by the second shock absorbing arm 322;

[0074] like Figure 2 As shown, the oblique baffle 31 abuts against the shock absorbing arm of the main shock absorber 1 32 and the shock absorbing arm of the main shock absorber 2 33;

[0075] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the shock absorbing and buffering device 2 4 includes a tensile energy absorbing column 1 41, a buffer arm 1 411, a limit arm 412, a tensile spring 1 413, a sliding base 2 42, a sub-shock absorber 43, a sub-shock absorbing arm 431, and a compression energy absorbing column 1 44;

[0076] Specifically, Figure 3As shown, the second sliding base 42 is fixedly installed on the steel plate 11, and the number of the second sliding base 42 is not less than two pairs. The sliding base 42 is two symmetrically arranged slide plates, and the slide plates are provided with slide grooves;

[0077] The stretching energy absorbing column 1 41 corresponds to the sliding base 2 42, and a rotating shaft is symmetrically arranged at the bottom of the stretching energy absorbing column 1 41, and the size of the rotating shaft corresponds to the sliding groove of the sliding base 42, so that the stretching energy absorbing column 1 41 can move forward and backward along the sliding groove of the sliding base 42 through the rotating shaft; the buffer arm 1 411 is connected to the stretching energy absorbing column 1 41 through a stretching spring 1 413, and a limiting arm 412 is fixedly arranged on the buffer arm 1 411 toward the direction of the slope 21;

[0078] The sub-shock absorber 43 is fixedly arranged on the steel plate 11, and the sub-shock absorber 43 is arranged at the rear part of the sliding base 42. The structure and components of the sub-shock absorber 43 are the same as those of the main shock absorber 32. The sub-shock absorber arm 431 of the sub-shock absorber 43 can abut against the stretching energy absorbing column 41, so that the sub-shock absorber 43 can absorb the impact of the stretching energy absorbing column 41 when the stretching energy absorbing column 41 moves backward.

[0079] The structure of the compression energy absorbing column 44 is the same as that of the main shock absorber 32. One end of the compression energy absorbing column 44 is fixedly connected to the steel plate 11, and the other end is in contact with the buffer column 41. Thus, the compression energy absorbing column 44 can absorb the impact of the buffer column 41 tilting backward.

[0080] In some embodiments of the present invention, Fig. 9 As shown, the enhanced version of the anti-collision vehicle blocker 100 is different from the above-mentioned anti-collision vehicle blocker 100 in that it further includes a shock absorbing and buffering device 3 5, and the tensile energy absorbing column 1 41 is replaced by a buffer column 1 45;

[0081] The shock absorbing and buffering device 3 5 comprises a tensile energy absorbing column 51, a buffer arm 2 52, a limiting structure 53 and a tensile spring 2 54;

[0082] The stretching energy absorbing column 51 is symmetrically fixed at the left and right ends of the steel plate 11, and a second stretching spring 54 is installed inside the stretching energy absorbing column 51. The second buffer arm 52 is connected to the stretching energy absorbing column 51 through the second stretching spring 54. A limiting structure 53 is fixed on the top of the second buffer arm 52. The limiting structure 53 can be a plate body of hard material, such as a steel plate, or a soft material, such as a mesh structure anti-collision net;

[0083] The buffer column 1 45 is an integral columnar structure, and the buffer column 1 45 is a hollow structure, thereby reducing the weight;

[0084] In some embodiments of the present invention, Fig.10As shown, the simplified version of the anti-collision vehicle blocker 100 is different from the above-mentioned anti-collision vehicle blocker 100 in that the compression energy absorption column 1 44 is replaced by a buffer column 2 46, and does not include a sliding base 2 42 and a sub-shock absorber 43;

[0085] The tensile energy absorbing column 1 41 is vertically fixed on the steel plate 11, and the number of the tensile energy absorbing column 1 41 is not less than 2; the buffer column 2 46 is an integral columnar structure, and the buffer column 2 46 is a hollow structure, thereby reducing the weight;

[0086] When using the anti-collision vehicle blocker 100, firstly, the universal wheel 122 is extended through the hydraulic lifting device 12, the chassis 1 is moved to the corresponding blocking area, the inclined baffle 31 is facing the driving direction of the vehicle, and the universal wheel 122 is retracted into the electric hydraulic lifting device 13, so that the anti-skid rubber layer 15 is in contact with the road surface, and the chassis 1 is fixed through the fixing holes 13 using ground nails or expansion screws, and further fixed by placing sandbags on the steel plate 11. After the fixing is completed, the fixing screws 121 are loosened. The hydraulic lifting device 12 is removed to prevent the blocking vehicle from hitting the hydraulic lifting device 12; when the blocking vehicle hits the anti-collision blocker 100, the front of the vehicle first hits the oblique baffle 31 of the shock absorbing and buffering device 3, and the oblique baffle 31 moves backward, driving the main shock absorber 32 to compress and absorb the kinetic energy of the blocking vehicle. When the damaged steel bars 3221 are installed on the shock absorbing arm 322, the damaged steel bars 3221 hit the shock absorbing arm 321 and break in sequence, thereby further absorbing the kinetic energy of the blocking vehicle;

[0087] The vehicle further impacts forward, and the front wheel of the vehicle passes through the slope 21, so that the forward direction of the vehicle is changed to an upward direction. The wheel passes through the slope 21 and hits the inclined baffle 31, thereby converting the forward impact potential energy of the vehicle into the upward kinetic energy and potential energy of the vehicle; the vehicle continues to impact upward and hits the tensile energy absorbing column 41, and the tensile energy absorbing column 41 moves backward through the sliding base 42, and further absorbs and reduces the impact kinetic energy of the buffer column 41 through the sub-shock absorber 43 and the compression energy absorbing column 44. At the same time, the vehicle continues to impact upward, and the front of the vehicle hits the limit arm 412, and the buffer arm 411 is stretched upward, and the tensile spring 413 is stretched to absorb energy, and the vehicle stops. All the impact kinetic energy of the vehicle is absorbed by the shock absorbing and buffering device 3 and the shock absorbing and buffering device 4, and is converted into the upward gravitational potential energy through the slope 21, thereby completely stopping the vehicle and avoiding the vehicle from rolling over or being seriously damaged.

[0088] When an anti-collision vehicle blocker 100 is used at a larger intersection or a wider road, one anti-collision vehicle blocker 100 is not sufficient, and multiple anti-collision vehicle blockers 100 can be spliced ​​and combined to ensure the blocking effect;

[0089] When an anti-collision vehicle blocker 100 is a reinforced version, the steps are the same as the above steps. After the blocked vehicle passes through the slope 21 and the oblique baffle 31 and hits the buffer column 1 45, it continues to impact obliquely upward and contacts the limiting structure 53, pulling the buffer arm 2 52 upward to stretch the tension spring 2 54 to absorb energy, and the vehicle stops. All the impact kinetic energy of the vehicle is absorbed by the shock absorbing and buffering device 1 3, the shock absorbing and buffering device 2 4 and the shock absorbing and buffering device 3 5, and is converted into oblique upward gravity potential energy through the slope 21, thereby completely stopping the blocked vehicle and avoiding the situation that the vehicle rolls over or is seriously damaged. The reinforced anti-collision vehicle blocker 100 is suitable for stopping large or heavy vehicles.

[0090] When an anti-collision vehicle blocker 100 is a simplified version, the steps are the same as the above steps. When the blocked vehicle passes through the slope 21 and the inclined baffle 31 and hits the stretching energy absorbing column 1 41, the stretching energy absorbing column 1 41 and the buffer column 2 46 bear the impact and transfer the impact to the steel plate 11, and the vehicle continues to impact obliquely upward, the front of the vehicle hits the limit arm 412, the buffer arm 1 411 stretches upward, the stretching spring 1 413 stretches to absorb energy, and the vehicle stops. All the impact kinetic energy of the vehicle is absorbed by the shock absorbing and buffering device 1 3 and the shock absorbing and buffering device 2 4, and is converted into oblique upward gravitational potential energy through the slope 21, thereby completely stopping the blocked vehicle and avoiding the vehicle from rolling over or being seriously damaged. The simplified version of the anti-collision vehicle blocker 100 is suitable for blocking light or small vehicles.

[0091] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
