Description

Technical Field

[0001] The invention relates to the field of police equipment, in particular to an anti-collision vehicle forced parking device. Background Art

[0002] The microwave vehicle forced stop device mainly consists of four parts: primary power supply and control, high voltage generator, wide spectrum pulse generator and broadband array antenna. This system is a high-power microwave electronic system that can force motor vehicles to stop and accept inspection outside the minimum allowed warning distance. The system is arranged at the checkpoint or sensitive department, and the antenna is facing the direction of possible oncoming vehicles. When a suspicious vehicle approaches, the vehicle forced stop system radiates high-power microwave pulses as needed. The electromagnetic field generated can significantly disrupt the normal operation of the on-board electronic fuel injection (EFI) system and its core component, the engine control unit (ECU), outside the warning distance, causing abnormal fuel injection volume and ignition timing, resulting in the loss of power of the car and inability to turn, forcing the suspected vehicle to stop and accept inspection, thereby achieving the purpose of protecting important targets from infringement. The system does not harm the driver and the vehicle, and the vehicle can be driven away by itself after the inspection.

[0003] Existing pole-type microwave vehicle forced stopping devices are usually disguised as roadblocks and set at security checkpoints. When a suspicious vehicle approaches, it is activated to force it to stop. However, this type of structure may be hit by a vehicle collision, causing the device to be damaged. Summary of the invention

[0004] The present invention aims to solve the above problems and provides an anti-collision vehicle forced parking device, which is specifically implemented by the following technical solutions:

The bottom plate of the packaging shell is limited by the end of the elastic telescopic rod, so that the protective tube rotates relative to the bottom plate of the packaging shell, so that the supporting rod disengages from the positioning groove and enters the notch of the bottom plate, so that the packaging shell falls toward the bottom of the protective tube until the upper end plate of the packaging shell squeezes the end of the elastic telescopic rod to form an elastic buffering effect, and finally the packaging shell carrying the movement falls into the protective tube.

[0015] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0016] like Figure 1 The anti-collision vehicle forced parking device shown in the figure includes a core part for directional emission of high-frequency pulse signals composed of a primary power supply, a high voltage generator, a wide-spectrum pulse generator and a broadband array antenna, and also includes a pressure plate 1, a varistor 2, a packaging shell 3, a concealing shell 4, a plurality of elastic telescopic rods 5, a protective tube 6, a base 7 and a driving motor 8; an installation pit 9 is excavated on the surface, and the base 7 is arranged in the installation pit; the protective tube 6 is rotatably arranged on the base, and a driving gear 61 is arranged on the lower outer wall of the protective tube, and the driving motor 8 is arranged on one side of the protective tube and is connected to the driving gear through a gear 81.

[0017] A plurality of support rods 62 are evenly distributed and radially extend inward along the upper edge of the protective tube 6; the movement part is installed in the packaging shell 3, and a bottom plate 31 is fixedly connected to the bottom of the packaging shell 3. The diameter of the bottom plate is larger than that of the packaging shell 3, and a plurality of notches 32 corresponding to the support rods are opened on the edge of the bottom plate, and radially extending positioning grooves 33 are provided on the bottom surface of the bottom plate located between adjacent notches; the bottom plate is placed on the upper end of the protective tube and the support rods 62 correspond to the positioning grooves one by one.

[0018] The elastic telescopic rod 5 is horizontally and evenly distributed within the edge of the installation pit, and the end of the elastic telescopic rod is located in the groove at the bottom of the packaging shell; the upper end of the packaging shell 3 is fixedly connected with an upper end plate 34, the diameter of the upper end plate 34 is also larger than the diameter of the packaging shell, and the bottom surface of the upper end plate that exceeds the side of the packaging shell is a frustum 35, and the end of the elastic telescopic rod 5 has an inclined surface 51 opposite to the frustum; the concealing shell cover is arranged above the installation pit, so that the packaging shell is located inside the concealing shell.

[0019] The pressure plate 1 is laid on the surface of one side of the installation pit, and the varistor 2 is arranged at the bottom of the pressure plate. The varistor is electrically connected to the signal input end of a controller, and the output end of the controller is connected to the drive motor. When the pressure plate is under pressure, the resistance signal of the varistor 2 undergoes a large mutation, and the drive motor 8 drives the protective tube to rotate, and the bottom plate of the packaging shell is limited by the end of the elastic telescopic rod, so that the protective tube rotates relative to the bottom plate of the packaging shell, so that the support rod 62 disengages from the positioning groove and enters the notch of the bottom plate, so that the packaging shell falls toward the bottom of the protective tube until the upper end plate of the packaging shell squeezes the end of the elastic telescopic rod to form an elastic buffering effect, and finally the packaging shell carrying the movement falls into the protective tube.

[0020] When the embodiment is used in actual applications, the ground around the installation pit and the pressure plate is covered with no-entry marking lines. When the vehicle moves to the pressure plate, it means that the distance between the core part located in the packaging shell and the vehicle is abnormal and too close. At this time, the drive motor is started, so that the packaging shell falls into the protective tube as a whole, thereby avoiding the core part from being damaged by impact. In this way, the drive motor needs to rotate at a very small angle, and the corresponding driving stroke is extremely short, so that the core part is freed from the risk of impact in the shortest time.

[0021] A buffer pad 63 is placed at the bottom of the protective tube 6. When the packaging shell is about to end its falling process, it is subjected to the elastic buffer force formed by the elastic telescopic rod. When the packaging shell finally contacts the bottom of the protective tube, the buffer pad forms a secondary buffer effect. The deceleration effect caused by the two buffers will not increase the risk of impact on the packaging shell.

[0022] The bottom of the protective tube 6 has a detachable bottom wall 64 that is threadedly connected; and a pin hole is opened on the bottom side of the bottom wall, and it is positioned on the pin column on the base through the pin hole; after the collision risk is eliminated, the protective tube can be lifted out of the installation pit from the base as a whole, and then the bottom wall can be removed and the packaging shell can be taken out.

[0023] The side wall of the concealing shell 4 has a vent hole 41, which can ensure that the packaging shell overshoots when it descends as much as possible, and the internal air pressure will not cause the packaging shell to be damaged when it falls.
