[0024] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0025] Embodiment 1 As Figures 1 - 4As shown in the figure, an automated road interception device includes an enclosure trolley 1, a vehicle 2, and a suspension mechanism 3. The enclosure trolley 1 can expand and contract horizontally. After the enclosure trolley 1 is deployed, it forms a wall structure and is used to intercept the vehicle 2 at a street or a railway crossing. The enclosure trolley 1 is provided with a lidar 4 connected to the control system to make the enclosure trolley 1 travel along a specified route; the vehicle 2 is used to transport the enclosure trolley 1; the suspension mechanism 3 is installed on the top of the vehicle 2 and is suitable for suspending the enclosure trolley 1.

[0026] The lidar 4 is electrically connected to the control system. The position of the enclosure trolley 1 can be accurately judged through the signal transmitted by the lidar 4, so that the enclosure trolley 1 can be transferred to a specified position according to the actual topographic map, realizing the automatic movement of the enclosure trolley 1. When not in use, the enclosure trolley 1 can be hung on the suspension mechanism 3 and quickly transferred by the vehicle 2. When the enclosure trolley 1 is needed, the enclosure trolley 1 can be lowered and moved to the interception position, and after the enclosure trolley 1 is deployed, a wall structure is formed.

[0027] When used for intercepting at a railway crossing, compared with the railing in the prior art, the wall structure formed by the enclosure trolley 1 has a better interception effect, which can prevent people from dodging and passing through, and can also prevent the vehicle driver of the vehicle 2 from not being able to find it in time under the condition of poor visibility. Since the enclosure trolley 1 has a self-positioning and transfer function, it does not consume manpower.

[0028] When used for street interception, the present invention can be used for closing large-area streets. For example, the enclosure trolley 1 can be placed at a specified street intersection according to the map, so as to intercept a certain area as a whole and realize street linkage control.

[0029] Enclosure trolley 1: As Figures 3 - 6 shown, the enclosure trolley 1 includes a connecting grid 5, an enclosure cloth 6, a locking assembly 7, and two half shells. The two ends of the connecting grid 5 and the enclosure cloth 6 are respectively connected to the two half shells. The enclosure cloth 6 covers both sides of the connecting grid 5. When the connecting grid 5 is deployed, the enclosure cloth 6 is deployed to form a wall structure. When the connecting grid 5 contracts, the two half shells are joined and closed, and the locking assembly 7 locks the two half shells. The connecting grid 5 is a fence door, similar to an electric retractable door. The connecting grid 5 can be provided with two or more layers to increase the thickness and stability. The enclosure cloth 6 is blocked outside the connecting grid 5. Warning slogans can be written on the enclosure cloth 6. The warning slogans exemplified in the appendix of the present invention are only one of the implementation manners, and other slogans can also be replaced according to the actual application occasion. The enclosure cloth 6 can be stored. When the connecting grid 5 contracts, the enclosure cloth 6 can be in a relaxed state. When the connecting grid 5 is deployed, the enclosure cloth 6 is tightened, and under the shielding of the enclosure cloth 6, the enclosure trolley 1 approximately becomes a wall structure (as Figure 13 shown in Figure 13As shown, compared with the traditional single-layer folding enclosure, the enclosure trolley 1 of the present invention has a relatively thick structure and can play a good interception role when unattended.

[0030] The locking assembly 7 is used to lock the two half shells after storage. One or more locking assemblies 7 can be provided. In this embodiment, one locking assembly 7 is provided at each of the upper and lower parts of the enclosure trolley 1. The locking assembly 7 can adopt the door lock structure in the prior art, or the following locking assembly 7: The locking assembly 7 includes a first electromagnetic pin 701, a sleeve 702 and a pin shaft 703. The first electromagnetic pin 701 is installed on one of the half shells. The sleeve 702 and the pin shaft 703 are respectively installed on the two half shells. The side walls of the sleeve 702 and the pin shaft 703 have a first jack 704. When the two half shells are joined and closed, the pin shaft 703 is inserted into the sleeve 702, and the first electromagnetic pin 701 is inserted into the first jack 704 of the sleeve 702 and the pin shaft 703.

[0031] For the convenience of description, the present invention names the two half shells as the left half shell 8 and the right half shell 9 respectively. As Figure 4 and Figure 7 shown, the first electromagnetic pin 701 is perpendicularly arranged with the sleeve 702 and the pin shaft 703. The first electromagnetic pin 701 and the sleeve 702 are fixed on the left half shell 8, and the pin shaft 703 is fixed on the right half shell 9. The first electromagnetic pin 701 includes a pin shell and a pin head. The pin head is attracted and retracted by the pin shell or repelled and extended by the pin shell under the action of magnetic force. When the pin shaft 703 is inserted into the sleeve 702, the pin head of the first electromagnetic pin 701 extends and is stuck into the first jack 704. The first electromagnetic pin 701 can be electrically connected to the control system, and the switch of the first electromagnetic pin 701 is controlled through the actual working state of the enclosure cloth 6.

[0032] Battery packs are placed at the bottoms of the two half shells to supply power to the electrical components on the enclosure trolley 1.

[0033] After the enclosure trolley 1 is contracted, the left half shell 8 and the right half shell 9 hide all the components of the enclosure trolley 1 inside, which can protect the internal components and at the same time make the appearance of the enclosure trolley 1 more beautiful. In the present invention, the outer shape formed after the enclosure trolley 1 is contracted is a symmetric structure with vertical planes at both ends and surrounded by eight side plates 24024 around. Components such as speakers and warning lights can be provided on the outer shell 11.

[0034] The half shell includes a frame 10 and a housing 11 covering the outside of the frame 10. The frame 10 supports the basic shape and also provides an installation surface for internal components. Both the connection grid 5 and the locking assembly 7 are installed on the frame 10. The left half shell 8 and the right half shell 9 can be separated along the symmetry center. To ensure smooth docking of the mating surfaces, the docking surfaces of the two half shells are inclined planes with an acute angle to the telescopic direction of the connection grid 5. Additionally, this design can make the positions where the two half shells collide and receive force during docking located at different cross-sections, thus avoiding damage to the components around the docking position caused by docking vibration.

[0035] Rollers are provided at the bottoms of the left half shell 8 and the right half shell 9. After they are separated, they can move independently, and the switch of the first electromagnetic pin 701 can be controlled by the movement state of the rollers.

[0036] Connection between the suspension mechanism 3 and the enclosure trolley 1: As Figure 6 shown, a hanging plug plate 12 is provided at the bottom of the suspension mechanism 3. A second jack 1201 is provided on the hanging plug plate 12. Slots 13 for inserting the hanging plug plate 12 are provided at the tops of the two half shells. Second electromagnetic pins 14 are respectively provided inside the two half shells. After the hanging plug plate 12 is inserted into the slot 13, the second electromagnetic pin 14 is inserted into the corresponding second jack 1201 to lock the enclosure trolley 1 and the suspension mechanism 3. The structure and principle of the second electromagnetic pin 14 are the same as those of the first electromagnetic pin 701.

[0037] The suspension mechanism 3 is suspended at the rear end of the vehicle 2. When the enclosure trolley 1 moves below the suspension mechanism 3, the hanging plug plate 12 of the suspension mechanism 3 moves downward until the hanging plug plate 12 is inserted into the slot 13. At this time, the pin head of the second electromagnetic pin 14 extends into the second jack 1201 to lock the hanging plug plate 12. The hanging plug plate 12 can be manually placed into the slot 13 or adsorbed into the slot 13 by a magnet.

[0038] Suspension mechanism 3: The suspension mechanism 3 includes a winding wheel 15, a suspension rope 16, a positioning outer cover 17, and a hanging head 18. The suspension rope 16 is wound around the winding wheel 15. The end of the suspension rope 16 is connected to the hanging head 18. The hanging plug plate 12 is located on the hanging head 18. The winding wheel 15 and the positioning outer cover 17 are fixed to the top of the vehicle 2. After the suspension rope 16 lifts the enclosure trolley 1, the enclosure trolley 1 is stuck inside the positioning outer cover 17. The winding wheel 15 is a prior art, usually including a drum and a motor. The suspension rope 16 is wound around the drum. The suspension rope 16 can be an iron chain, a nylon rope, or a steel wire rope, etc. The hanging head 18 can fit with the top surface of the enclosure trolley 1 to enable the hanging plug plate 12 to be successfully inserted into the slot 13.

[0039] The shape of the positioning outer cover 17 is as Figure 1As shown in the figure, the positioning outer cover 17 is a hollow frame 10, which has the same shape as the upper half of the closed enclosure trolley 1. The upper half of the enclosure trolley 1 fits against the inner surface of the positioning outer cover 17, and the enclosure trolley 1 is limited by surface fitting to prevent it from shaking.

[0040] Embodiment 2 In the prior art, the enclosures all use roller supports. The supporting surface of the rollers is small, the walking stability is low, and the supporting strength is also small, which is not suitable for walking over long distances and uneven ground. Therefore, on the basis of Embodiment 1, the following improvements are made in this embodiment: As Figure 4 and Figure 5 shown in the figure, triangular wheels 19 are installed at the bottom of the enclosure trolley 1. A crawler 20 is provided on the triangular wheels 19. A wheel frame 21 and a transfer frame 22 are connected between the triangular wheels 19 and the semi-housing. The transfer frame 22 is fixed to the semi-housing, the wheel frame 21 is fixed to the triangular wheels 19, a corner motor 23 is installed on the transfer frame 22, and the rotating shaft of the corner motor 23 is arranged perpendicular to the rotation center of the triangular wheels 19. The output end of the corner motor 23 is connected to the wheel frame 21 and drives the wheel frame 21 to rotate. The triangular wheels 19 are composed of three wheel axles. The crawler 20 is enclosed in a triangle along the three wheel axles. The three wheel axles tighten the crawler 20. At least one of the three wheel axles is equipped with a driving motor to control its rolling forward. The width of the crawler 20 is relatively large, which can ensure the running balance. Two wheel axles of the triangular wheels 19 are located below, increasing the contact surface between the crawler 20 and the ground. At the same time, when encountering an uneven surface, it can also stably cross over relying on the toughness of the crawler 20 itself.

[0041] The corner motor 23 is used to rotate the triangular wheels 19 to change the traveling direction of the enclosure trolley 1. Since the roads usually intersect at right angles, the corner angle of the enclosure trolley 1 in the present invention only needs to be set at 90°, that is, the corner angle of the corner motor 23 is set at 90°.

[0042] Embodiment 3 On the basis of the above embodiments, the suspension mechanism 3 further includes a plurality of roof racks 24 and cantilevers 25. The roof racks 24 and the cantilevers 25 are arranged crosswise. The roof racks 24 are fixed to the top of the vehicle 2, and the reel 15 is fixed to the cantilever 25. The roof racks 24 are arranged along the width direction of the vehicle 2, and the cantilevers 25 are arranged along the length direction of the vehicle 2.

[0043] As Figures 8 - 12As shown in the figure, the roof rack 24 includes a cross beam 2401, legs 2402 and a connecting plate 2403. The top of the cross beam 2401 has a number of mounting holes 24011, and the bottom of the cross beam 2401 has a slide rail 24012. The cantilever 25 is connected to the cross beam 2401 through the mounting holes 24011. The legs 2402 are slidably matched with the cross beam 2401. The legs 2402 are connected to the vehicle 2. The connecting plate 2403 and the legs 2402 are clamped on both sides of the slide rail 24012 and fixed by bolts. The legs 2402 are used to support the cross beam 2401. The mounting holes 24011 at the top of the cross beam 2401 are evenly distributed along the length direction. Appropriate mounting holes 24011 can be selected according to the width of the vehicle 2 to connect with the cantilever 25. A long groove is formed at the bottom of the cross beam 2401 to form the slide rail 24012. The connecting plate 2403 is located inside the cross beam 2401 and cooperates with the external legs 2402 to clamp the cross beam 2401, making the three relatively fixed. Compared with the traditional roof rack 24, the roof rack 24 in this embodiment is more flexible and convenient to disassemble and assemble.

[0044] Among them, the legs 2402 can but are not limited to adopt the following structure: such as Figure 9 and Figure 12 As shown in the figure, it includes a support plate 24021, a top plate 24022 and a bottom plate 24023 located at the upper and lower ends of the support plate 24021, and side plates 24024 located on the side of the support plate 24021. The top plate 24022 is arranged in contact with the slide rail 24012. There is a height difference between the side plates 24024 and the bottom plate 24023. When the bottom plate 24023 extends into the roof, the side plates 24024 are in contact with the top surface of the vehicle 2; a hoop 24025 sleeved outside the cross beam 2401 is also provided at the top of the legs 2402. The hoop 24025 has the same cross-sectional shape as the cross beam 2401 to achieve sliding fit. The hoop 24025 is sleeved outside the cross beam 2401 and fixed to the connecting plate 2403 with bolts after sliding to a suitable position. The side plates 24024 are located on both sides of the support plate 24021 to play a strengthening role. The top plate 24022 is a component fixed to the connecting plate 2403 by bolts, and the bottom plate 24023 is connected to the roof. The bottom plate 24023 is stuck in the socket reserved on the roof, and the insertion depth of the legs 2402 is limited by the contact between the side plates 24024 and the roof.

[0045] In further design, in order to improve the strength of the legs 2402, such as Figure 9 and Figure 12 As shown in the figure, the legs 2402 further include a reinforcing plate 24026 and a locking pin 24027. The reinforcing plate 24026 has a convex portion 26 located outside the support plate 24021 and protruding from the surface of the support plate 24021, and a bent portion 27 extending into the roof. The bent portion 27 is wrapped under the bottom plate 24023. There is a plugging portion 28 obliquely inserted into the support plate 24021 above the reinforcing plate 24026. Such asFigure 9 As shown, the support plate 24021 inclines outward, and the reinforcement plate 24026 is located outside the support plate 24021, which can prevent the support plate 24021 from being bent and deformed. The bottom of the reinforcement plate 24026 is limited by the bottom plate 24023, and the top is fixed through the insertion part 28. With the cooperation of the upper and lower parts, the relative fixation of the reinforcement plate 24026 and the support plate 24021 is achieved. The insertion part 28 is inserted in an obliquely upward manner, and the bending part 27 bends and wraps the bottom plate 24023. After the assembly is completed, the reinforcement plate 24026 will not be separated from the support plate 24021 randomly. The locking pin 24027 passes through the reinforcement plate 24026 and the support plate 24021 and is locked by a nut to prevent the reinforcement plate 24026 from shaking.
