Description

Technical Field

[0001] The present invention relates to the technical field of safety assurance technology, and in particular to a buffer device for stopping an out-of-control motor vehicle. Background Art

[0002] Highways have the advantages of high transportation efficiency, large freight capacity, and low transportation costs. Nowadays, cars are a common means of transportation. Cars move very fast and have great inertia, so when a car loses control, it is easy to cause a serious traffic accident.

[0003] An out-of-control vehicle on a highway maintains a very high speed. When the traffic control department receives a message about the out-of-control vehicle, it will send two vehicles, one in front and one behind, to drive at the front and rear of the out-of-control vehicle to slow it down. The front vehicle slows down and presses against the front of the out-of-control vehicle to slow it down. The front of the out-of-control vehicle contacts the rear of the front vehicle, lacking a buffer and docking device. Not only can it not effectively protect the blocked vehicle, the direct contact also greatly increases the risk of blocking, which can easily lead to an escalation of the accident.

[0004] Therefore, there is an urgent need for a buffer device for stopping out-of-control motor vehicles to solve the above-mentioned problems. Summary of the Invention

[0005] The object of the present invention is to provide a buffer device for blocking out-of-control motor vehicles, which has a simple structure and is easy to use, can effectively protect the blocked vehicle, and effectively control the out-of-control vehicle.

[0006] The embodiment of the present invention is achieved as follows:

[0007] An embodiment of the present application provides a buffer device for stopping an out-of-control motor vehicle, which includes a rear base frame, a lifting mechanism is provided on the rear base frame, and an inclined bottom plate is provided on the lifting mechanism; limited baffles are provided on both sides of the rear base frame, and a buffer plate is provided on the rear base frame, and the buffer plate is provided above the inclined bottom plate.

[0008] In some embodiments of the present invention, a vertical slide groove is provided on the rear base frame, a connecting piece is slidably connected in the vertical slide groove, and the connecting piece is connected to the inclined bottom plate; the lifting mechanism is connected to the connecting piece.

[0009] In some embodiments of the present invention, the above-mentioned lifting mechanism includes a threaded screw, which is arranged in a vertical slide groove and connected to the rear frame of the vehicle through a bearing; a threaded through hole is provided in the middle of the connecting piece, and the threaded screw is threadedly connected to the threaded through hole; and a driving motor is provided in connection with the threaded screw.

[0010] In some embodiments of the present invention, there are two threaded screws, a first gear is provided at the top of the threaded screw, and a second gear is provided on the output shaft of the drive motor; the two sides of the second gear are respectively engaged with the two first gears, and the thread directions of the two threaded screws are opposite.

[0011] In some embodiments of the present invention, the inclined bottom plate includes a horizontal plate and an inclined plate, one side of the horizontal plate is hinged to one side of the inclined plate, and the other side of the horizontal plate is fixedly connected to the connecting member; a telescopic rod is provided between the horizontal plate and the inclined plate.

[0012] In some embodiments of the present invention, the telescopic rod is a hydraulic rod, and the top of the hydraulic rod is hinged to the inclined plate.

[0013] In some embodiments of the present invention, the above-mentioned limit baffle is hinged to the base frame, and an arc baffle is provided at one end of the limit baffle close to the base frame; the angle between the limit baffle and the arc baffle is 110°-125°.

[0014] In some embodiments of the present invention, a plurality of rubber rollers are arranged on the inner side of the limiting baffle.

[0015] In some embodiments of the present invention, the buffer plate is provided in an arc-shaped protrusion, and its interior is hollow and made of rubber material; a plurality of exhaust ports are provided on the buffer plate and communicated with the interior.

[0016] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0017] The front of an out-of-control vehicle contacts the rear of the vehicle in front, lacking a buffer and docking device. This not only fails to effectively protect the blocked vehicle, but also easily leads to an escalation of the accident. The present invention provides a buffer device for blocking out-of-control vehicles, comprising a rear base frame, a lifting mechanism disposed on the rear base frame, and an inclined bottom plate disposed on the lifting mechanism; limit baffles are disposed on both sides of the rear base frame, and a buffer plate is disposed on the rear base frame, and the buffer plate is disposed above the inclined bottom plate.

[0018] The present invention utilizes an inclined base plate installed on the lifting mechanism, allowing the operator to adjust the height of the inclined base plate through the lifting mechanism. This allows the operator to enter under the uncontrolled vehicle during contact and, through the interaction between the two vehicles, lift the front end of the trailing vehicle, lifting the front wheels off the ground. This prevents the uncontrolled vehicle's front wheels from deflecting and changing its driving trajectory, while also cutting off the power source of the front-drive vehicle. Furthermore, the position-limiting baffles on both sides of the rear frame effectively limit the vehicle's position and prevent it from tilting sideways. The provision of a buffer plate effectively prevents significant damage from direct contact between the two vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0025] Example:

[0026] Please refer to Figure 1-2 This embodiment provides a buffer device for stopping an out-of-control motor vehicle, which includes a rear base frame 1, a lifting mechanism is provided on the rear base frame 1, and an inclined bottom plate is provided on the lifting mechanism; limited baffles 2 are provided on both sides of the rear base frame 1, and a buffer plate 3 is provided on the rear base frame 1, and the buffer plate 3 is provided above the inclined bottom plate.

[0027] The front of the out-of-control vehicle contacts the rear of the leading vehicle, lacking a buffer and docking device; not only can it not effectively protect the blocked vehicle, but it can also easily cause the accident to escalate. The present invention provides an inclined bottom plate on the lifting mechanism, allowing the operator to adjust the height of the inclined bottom plate through the lifting mechanism, so that the operator can enter under the out-of-control vehicle during vehicle contact and lift the front of the rear vehicle under the interaction of the two vehicles, so that the front wheels are off the ground. This can not only prevent the front wheels of the out-of-control vehicle from deflecting and changing the driving trajectory, but also cut off the power source of the front-drive vehicle. At the same time, the limit baffles 2 provided on both sides of the rear base frame 1 can effectively limit the vehicle to prevent it from deflecting to the side; the provision of the buffer plate 3 can effectively prevent the two vehicles from directly contacting each other and causing huge damage.

[0028] In some embodiments of the present invention, a vertical chute 4 is provided on the rear chassis 1. A connector 5 is slidably connected within the chute 4 and is connected to the inclined base plate. A lifting mechanism is connected to the connector 5. The lifting mechanism includes a threaded screw 6, which is disposed within the chute 4 and connected to the rear chassis 1 via a bearing. A threaded through hole is provided in the center of the connector 5, into which the screw 6 is threadedly connected. A drive motor 7 is connected to the screw 6. The screw 6 is threadedly connected to the through hole, and the drive motor 7 can rotate the screw 6 to raise or lower the connector 5. The threaded connection of the connector 5 effectively prevents the connector 5 from sliding down due to excessive vehicle weight.

[0029] In some embodiments of the present invention, two threaded screws 6 are provided. A first gear 8 is disposed at the top of each threaded screw 6, and a second gear 9 is disposed on the output shaft of a drive motor 7. The second gear 9 meshes with the two first gears 8 on either side, and the threads of the two threaded screws 6 run in opposite directions. Furthermore, the radius of the second gear 9 is smaller than that of the first gear 8, effectively reducing the output power requirement of the drive motor 7.

[0030] In some embodiments of the present invention, the inclined base plate includes a horizontal plate 10 and an inclined plate 11. One side of the horizontal plate 10 is hingedly connected to one side of the inclined plate 11, and the other side of the horizontal plate 10 is fixedly connected to the connector 5. A telescopic rod 12 is provided between the horizontal plate 10 and the inclined plate 11. The telescopic rod 12 is a hydraulic rod, the top of which is hingedly connected to the inclined plate 11. This hinged connection allows a worker to control the tilt angle of the inclined plate 11 to a desired position, thereby increasing the applicability of the device.

[0031] In some embodiments of the present invention, the stopper 2 is hingedly connected to the base frame, and a curved stopper 13 is provided at one end of the stopper 2, which is closest to the base frame. The angle between the stopper 2 and the curved stopper 13 is 110°-125°. The arrangement of the curved stopper 13 ensures that when an uncontrolled vehicle abuts the curved stopper 13, it drives the stopper 2 inward to restrain the uncontrolled vehicle.

[0032] In some embodiments of the present invention, a plurality of rubber rollers 14 are arranged on the inner side of the limit baffle 2. The arranged rubber rollers 14 can effectively reduce the friction collision between the out-of-control vehicle and the limit baffle 2, reducing friction damage while limiting the position.

[0033] In some embodiments of the present invention, the baffle 3 is an arc-shaped raised structure with a hollow interior composed of a rubber material. Several exhaust ports 15 are provided on the baffle 3, communicating with the interior. If the impact force is relatively small, the rubber material of the baffle 3 can further cushion the impact and reduce damage. If the impact force is relatively large, the air inside the baffle 3, limited by the size of the exhaust ports 15, increases its internal pressure, effectively preventing the uncontrolled vehicle from directly colliding with the base frame.

[0034] In summary, an embodiment of the present invention provides a buffer device for blocking out-of-control motor vehicles, which includes a rear base frame 1, a lifting mechanism provided on the rear base frame 1, and an inclined bottom plate provided on the lifting mechanism; limit baffles 2 are provided on both sides of the rear base frame 1, and a buffer plate 3 is provided on the rear base frame 1, and the buffer plate 3 is provided above the inclined bottom plate. The present invention provides an inclined bottom plate on the lifting mechanism, so that the operator can adjust the height of the inclined bottom plate through the lifting mechanism, so that the operator can enter under the out-of-control vehicle during vehicle contact and lift the front of the rear vehicle under the interaction of the two vehicles, so that the front wheels are off the ground. This can not only prevent the front wheels of the out-of-control vehicle from deflecting and changing the driving trajectory, but also cut off the power source of the front-wheel drive vehicle. At the same time, the limit baffles 2 provided on both sides of the rear base frame 1 can effectively limit the vehicle to prevent it from deflecting to the side; the provision of the buffer plate 3 can effectively prevent the direct contact between the two vehicles from causing huge damage.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
