Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of security equipment, in particular to a projectile vehicle stopping device. BACKGROUND

[0002] Nowadays, in the process of law enforcement, there is often a work link of checking vehicles on the road, and the vehicles need to be stopped by setting up a checkpoint in this process. However, vehicles may rush through the checkpoint to avoid inspection, and the police cannot stop them quickly, so a vehicle stopper needs to be set up when setting up a checkpoint to prevent this situation. The existing vehicle stopper is generally a large vehicle stopper, which needs to be set up in advance to stop the vehicles that rush through the checkpoint. However, in some special situations, for example, the vehicles that rush through the checkpoint suddenly change the route and do not drive according to the predicted road conditions, the vehicle stopping and intercepting method has disadvantages, and the transportation of the large vehicle stopper device is relatively complex, and the maintenance cost is also high. SUMMARY

[0003] The main purpose of the present application is to provide a projectile vehicle stopping device to at least solve the problems of complex transportation and high maintenance cost of the existing vehicle stopper.

[0004] In order to achieve the above purpose, the present application provides a projectile vehicle stopping device, which comprises a ground platform, an outer air bag and a thorn body mechanism. The bottom of the outer air bag is sleeved on the ground platform. The inner part of the outer air bag and the upper surface of the ground platform form an airtight space. The thorn body mechanism is arranged in the airtight space. When the wheels damage the outer air bag, the thorn body mechanism abuts against the wheels and damages the wheels to stop the movement of the vehicle.

[0005] Further, the outer air bag is made of elastic material.

[0006] Further, an air inlet valve is formed on the outer air bag, and gas enters the airtight space through the air inlet valve to make the outer air bag expand.

[0007] Further, the thorn body mechanism comprises a main thorn body and a secondary thorn body. The main thorn body is arranged on the upper surface of the ground platform. The secondary thorn body comprises two parts, which are rotatably arranged on both sides of the upper surface of the ground platform and abut against the inner side wall of the outer air bag. When the wheels damage the outer air bag, the main thorn body abuts against the wheels and damages the wheels, and the two secondary thorn bodies are respectively turned over to the two sides of the ground platform to damage other wheels.

[0008] Further, the secondary thorn body comprises a first thorn segment and a second thorn segment. One end of the first thorn segment is rotatably arranged on one side of the upper surface of the ground platform and abuts against the inner side wall of the outer air bag. The second thorn segment is rotatably connected to the other end of the first thorn segment. When the outer air bag is in contact with the wheels and is broken, the first thorn segment is turned over to the outside and drives the second thorn segment to be synchronously turned over to the outside.

[0009] Further, the main thorn body is upward; the two first thorn segments are both inward of the outer air bag; the two second thorn segments are opposite to the two first thorn segments.

[0010] Further, the main thorn body, the first thorn segment and the second thorn segment are metal materials.

[0011] The projectile vehicle stopping device provided by the application comprises a platform, an outer air bag and a thorn body mechanism; the bottom of the outer air bag is sleeved on the platform; the inner part of the outer air bag and the upper surface of the platform form an air-tight space; the vehicle stopping thorn body mechanism is arranged in the air-tight space; when the wheels damage the outer air bag, the thorn body mechanism abuts against the wheels and damages the wheels to stop the vehicle from moving, thereby solving the problems of complex transportation and high maintenance cost of the vehicle stopper in the prior art.

[0017] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0018] The projectile vehicle stopping device according to the embodiment of the application, as shown in Figure 1As shown, the device includes a base 10, an external airbag 20, and a piercing mechanism 30. The bottom of the external airbag 20 is fitted onto the base 10. The interior of the external airbag 20 and the upper surface of the base 10 form an airtight space. The piercing mechanism 30 is located within the airtight space. When the wheel damages the external airbag 20, the piercing mechanism 30 comes into contact with the wheel and damages it to stop the vehicle from moving. In practical use, the operator carries the vehicle-launching device onto the vehicle. When the vehicle reaches the front of the vehicle to be intercepted, the vehicle-launching device is launched onto the ground. When the wheel of the vehicle to be intercepted comes into contact with the external airbag 20, the external force will cause the external airbag 20 to rupture, thereby causing the wheel to come into contact with the piercing mechanism 30. The piercing mechanism 30 damages the wheel to forcibly stop the vehicle, solving the problems of complex transportation and high maintenance costs of existing vehicle stoppers.

[0019] In specific implementation, such as Figure 1 As shown, the external airbag 20 is made of elastic material and coated with a reflective dye material. On the one hand, the elastic material makes the external airbag 20 airtight, and the interior can contain gas to form an airtight space; on the other hand, the reflective effect makes the vehicle stopper more conspicuous, so as to achieve the warning function and prevent other vehicles from accidentally touching it.

[0020] In specific implementation, such as Figure 1 As shown, an air inlet valve 21 is provided on the outer airbag 20. Gas enters the airtight space through the air inlet valve 21 to inflate the outer airbag 20. The air inlet valve 21 is located on one side of the top of the outer airbag 20. During the transportation of the projectile blocking device, the gas in the outer airbag 20 can be discharged before handling, which is convenient for handling. In actual use, gas can be filled into the outer airbag 20 through the air inlet valve 21.

[0021] In specific implementation, such as Figure 1 and Figure 2 As shown, the piercing mechanism 30 includes a main piercing body 31 and secondary piercing bodies 32. The main piercing body 31 is disposed on the upper surface of the platform 10. There are two secondary piercing bodies 32, which are rotatably disposed on both sides of the upper surface of the platform 10 and abut against the inner wall of the outer airbag 20. When the wheel damages the outer airbag 20, the main piercing body 31 abuts against the wheel and damages the wheel, while the two secondary piercing bodies 32 flip to both sides of the platform 10 to damage other wheels. The contact area between the main piercing body 31 and the wheel is limited, and it may not be possible to damage the wheels of some special vehicles by the main piercing body 31 alone. The secondary piercing bodies 32 increase the contact area between the piercing body and the wheel, making the interception success rate of the projectile vehicle blocking device higher.

[0022] In specific implementation, such as Figure 1 and Figure 2As shown, the auxiliary spike 32 includes a first spike segment 321 and a second spike segment 322; one end of the first spike segment 321 is rotatably disposed on one side of the upper surface of the platform 10 and abuts against the inner wall of the outer airbag 20; the second spike segment 322 is rotatably connected to the other end of the first spike segment 321; wherein, when the outer airbag 20 contacts the wheel, it ruptures, causing the first spike segment 321 to flip outward and driving the second spike segment 322 to flip outward synchronously. After the outer airbag 20 ruptures, the force that constricts the first spike segment 321 and the second spike segment 322 disappears, causing the first spike segment 321 and the second spike segment 322 to flip outward and unfold instantaneously.

[0023] In specific implementation, such as Figure 1 and Figure 2 As shown, the main piercing body 31 faces upward; the two first piercing segments 321 both face the inside of the outer airbag 20, and the two second piercing segments 322 correspond to the two first piercing segments 321. The two first piercing segments 321 face the inside of the outer airbag, and when they are flipped outward to contact the ground, their piercing bodies face upward; when the two second piercing segments 322 are flipped and contact the ground, their piercing bodies also face upward and are in contact with the wheel.

[0024] In specific implementation, such as Figure 2 As shown, the main spike 31, the first spike segment 321, and the second spike segment 322 are all made of metal. Metal has high strength and is relatively easy to maintain. Using metal for the spike part can ensure effective damage to the wheel.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
