DETAILED DESCRIPTION

[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Example 1

[0039] like Figures 1-4 As shown, an automated road interception device includes a barrier trolley 1, a vehicle 2 and a suspension mechanism 3. The barrier trolley 1 can be extended and retracted laterally. When the barrier trolley 1 is unfolded, it forms a wall structure and is used to intercept vehicles 2 on streets or railway crossings. The barrier trolley 1 is provided with a laser radar 4 connected to the control system, so that the barrier trolley 1 can move along a designated route; the vehicle 2 is used to transport the barrier trolley 1; the suspension mechanism 3 is installed on the top of the vehicle 2 and is suitable for suspending the barrier trolley 1.

[0040] The laser radar 4 is electrically connected to the control system, and the position of the barrier trolley 1 can be accurately determined based on the signals transmitted by the laser radar 4. The barrier trolley 1 can then be moved to a designated location based on the actual terrain map, achieving automatic movement of the barrier trolley 1. When not in use, the barrier trolley 1 can be suspended from the suspension mechanism 3 and quickly transported by the vehicle 2. When the barrier trolley 1 is needed, it can be lowered and moved to the interception position. The barrier trolley 1 can then be deployed to form a wall structure.

[0041] When used to intercept at a railway intersection, the wall structure formed by the barrier trolley 1 has a better interception effect than the existing guardrails, preventing people from evading and passing through, and also preventing the driver of the vehicle 2 from not being able to see in time in poor visibility conditions. Since the barrier trolley 1 has a self-positioning and transfer function, it does not consume manpower.

[0042] When used for street interception, the present invention can be used for closing streets in large areas. For example, a barrier vehicle 1 can be placed at a designated street entrance according to a map, thereby intercepting a whole area and realizing street linkage control.

[0043] Enclosure car 1:

[0044] like Figure 3-Figure 6As shown, the enclosure trolley 1 includes a connecting fence 5, an enclosure cloth 6, a locking assembly 7 and two half shells. The two ends of the connecting fence 5 and the enclosure cloth 6 are respectively connected to the two half shells. The enclosure cloth 6 blocks the two sides of the connecting fence 5. When the connecting fence 5 is unfolded, the enclosure cloth 6 is unfolded to form a wall structure. When the connecting fence 5 is retracted, the two half shells are connected and closed, and the locking assembly 7 locks the two half shells. The connecting fence 5 is a fence door, similar to an electric telescopic door. The connecting fence 5 can be set with two or more layers to increase thickness and stability. The enclosure cloth 6 blocks the outside of the connecting fence 5. Warning slogans can be written on the enclosure cloth 6. The present invention is attached Figure 13 The warning slogan in the example is only one embodiment, and other slogans can be replaced according to the actual application needs. The enclosure cloth 6 can be stored. When the connecting fence 5 is retracted, the enclosure cloth 6 can be in a relaxed state. When the connecting fence 5 is unfolded, the enclosure cloth 6 is tightened, and under the cover of the enclosure cloth 6, the enclosure trolley 1 is approximately a wall structure (such as Figure 13 As shown), compared with the traditional single-layer folding enclosure, the enclosure trolley 1 described in the present invention has a thicker structure and can play a good interception role when there is no one guarding it.

[0045] The locking assembly 7 is used to lock the two half shells after storage. It can be provided with one or more. In this embodiment, a locking assembly 7 is provided at the upper part and the lower part 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 can be used:

[0046] The locking assembly 7 includes a first electromagnetic pin 701, a sleeve 702 and a pin 703. The first electromagnetic pin 701 is installed on one of the half shells, and the sleeve 702 and the pin 703 are installed on the two half shells respectively. The side walls of the sleeve 702 and the pin 703 have a first socket 704. When the two half shells are connected and closed, the pin 703 is inserted into the sleeve 702, and the first electromagnetic pin 701 is inserted into the first socket 704 of the sleeve 702 and the pin 703.

[0047] For ease of description, the present invention names the two half shells as the left half shell 8 and the right half shell 9, respectively. Figure 4 and Figure 7 As shown, the first electromagnetic pin 701 is arranged vertically to 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 in the first socket 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 by the actual working state of the enclosure cloth 6.

[0048] Battery packs are placed at the bottom of the two half shells to supply power to the electrical components on the enclosure trolley 1.

[0049] When the enclosure trolley 1 is retracted, the left and right half shells 8 and 9 conceal all components of the trolley 1, protecting them and enhancing their appearance. In the present invention, the retracted enclosure trolley 1 forms a symmetrical structure with vertical planes at both ends and surrounded by eight side panels. Components such as speakers and warning lights can be mounted on the outer shell 11.

[0050] The half-shells comprise a frame 10 and an outer shell 11 encasing the frame 10. The frame 10 supports the basic exterior and also provides a mounting surface for internal components. The connecting grid 5 and locking assembly 7 are both mounted on the frame 10. The left and right half-shells 8 and 9 can be separated along their centers of symmetry. To ensure smooth mating, the mating surfaces of the two half-shells are inclined planes at an acute angle to the direction of extension and contraction of the connecting grid 5. Furthermore, this design allows the collision forces of the two half-shells to be located at different cross-sections during mating, thus preventing damage to components surrounding the mating location caused by vibration from the mating.

[0051] The bottom of the left half shell 8 and the bottom of the right half shell 9 are both provided with rollers. When the two 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.

[0052] Connection between the suspension mechanism 3 and the enclosure trolley 1:

[0053] like Figure 6 As shown, the bottom of the suspension mechanism 3 is provided with a hanging plate 12, which is provided with a second insertion hole 1201. The tops of the two half-shells have slots 13 for inserting the hanging plate 12. The two half-shells are each provided with a second electromagnetic pin 14. When the hanging plate 12 is inserted into the slot 13, the second electromagnetic pin 14 is inserted into the corresponding second insertion hole 1201, locking 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.

[0054] 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 plate 12 of the suspension mechanism 3 moves downward until the hanging plate 12 is inserted into the slot 13. At this time, the pin head of the second electromagnetic pin 14 extends into the second socket 1201, locking the hanging plate 12. The hanging plate 12 can be placed into the slot 13 manually or by being attracted by a magnet.

[0055] Suspension mechanism 3:

[0056] The suspension mechanism 3 includes a reel 15, a lifting rope 16, a positioning cover 17, and a hanging head 18. The lifting rope 16 is wound around the reel 15, and the end of the lifting rope 16 is connected to the hanging head 18. The hanging plug plate 12 is located on the hanging head 18. The reel 15 and the positioning cover 17 are fixed to the top of the vehicle 2. When the lifting rope 16 lifts the enclosure trolley 1, the enclosure trolley 1 is stuck in the positioning cover 17. The reel 15 is a prior art, usually including a drum and a motor. The lifting rope 16 is wound around the drum. The lifting rope 16 can be an iron chain, nylon rope, or steel wire rope. The hanging head 18 can fit with the top surface of the enclosure trolley 1, so that the hanging plug plate 12 can be successfully inserted into the slot 13.

[0057] The shape of the positioning cover 17 is as follows Figure 1 As shown, the positioning outer cover 17 is a hollow frame 10, which has the same shape as the upper half of the enclosure trolley 1 after closing. The upper half of the enclosure trolley 1 is fitted with the inner surface of the positioning outer cover 17, and the enclosure trolley 1 is limited by the surface fitting to prevent the enclosure trolley 1 from shaking.

[0058] Example 2

[0059] The existing enclosures all use rollers for support, which have a small support surface, low walking stability, and low support strength, making them unsuitable for walking over long distances or on uneven surfaces. To this end, this embodiment makes the following improvements based on the first embodiment:

[0060] like Figure 4 and Figure 5 As shown, the bottom of the enclosure trolley 1 is equipped with a triangular wheel 19, on which a track 20 is provided. A wheel frame 21 and an adapter frame 22 are connected between the triangular wheel 19 and the half-shell. The adapter frame 22 is fixed to the half-shell, and the wheel frame 21 is fixed to the triangular wheel 19. A cornering motor 23 is installed on the adapter frame 22. The rotating shaft of the cornering motor 23 is arranged perpendicular to the rotation center of the triangular wheel 19. The output end of the cornering motor 23 is connected to the wheel frame 21 and drives the wheel frame 21 to rotate. The triangular wheel 19 is composed of three axles. The track 20 forms a triangle along the three axles. The three axles tighten the track 20. At least one of the three axles is equipped with a drive motor to control its rolling forward. The track 20 is relatively wide to ensure stable operation. The two axles of the triangular wheel 19 are located at the bottom, which increases the contact area between the track 20 and the ground. At the same time, when encountering uneven surfaces, the track 20 can also rely on its own toughness to stably cross.

[0061] The turning motor 23 is used to rotate the triangular wheel 19 to change the direction of travel of the enclosure trolley 1. Since roads usually intersect at right angles, the turning angle of the enclosure trolley 1 in the present invention only needs to be set to 90°, that is, the turning angle of the turning motor 23 is set to 90°.

[0062] Example 3

[0063] Based on the above embodiment, the suspension mechanism 3 further includes a plurality of roof frames 24 and cantilevers 25. The roof frames 24 and cantilevers 25 are arranged crosswise. The roof frames 24 are fixed to the top of the vehicle 2, and the reel 15 is fixed to the cantilevers 25. The roof frames 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.

[0064] like Figures 8-12 As shown, the roof rack 24 includes a crossbeam 2401, support legs 2402 and a connecting plate 2403. The top of the crossbeam 2401 has a plurality of mounting holes 24011, and the bottom of the crossbeam 2401 has a slide rail 24012. The cantilever 25 is connected to the crossbeam 2401 through the mounting holes 24011. The support legs 2402 slide in conjunction with the crossbeam 2401. The support legs 2402 are connected to the vehicle 2. The connecting plate 2403 and the support legs 2402 are clamped on both sides of the slide rail 24012 and fixed by bolts. The legs 2402 support the crossbeam 2401. Mounting holes 24011 are evenly spaced along the length of the crossbeam 2401. The appropriate mounting holes 24011 can be selected based on the width of the vehicle 2 to connect to the cantilever 25. A slot is formed at the bottom of the crossbeam 2401 to form a slide rail 24012. A connecting plate 2403, located within the crossbeam 2401, cooperates with the external legs 2402 to clamp the crossbeam 2401, securing the three components relative to each other. Compared to conventional roof racks 24, the roof rack 24 of this embodiment is more flexible and convenient to assemble and disassemble.

[0065] Among them, the supporting legs 2402 can be but not limited to adopt the following structures: Figure 9 and Figure 12 As shown, the support leg 2402 comprises 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 sides of the support plate 24021. The top plate 24022 is arranged in a close relationship 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 abut against the top surface of the vehicle 2. A clamp 24025 is also provided on the top of the support leg 2402, which is mounted on the outside of the crossbeam 2401. The clamp 24025 has the same cross-sectional shape as the crossbeam 2401, achieving a sliding fit. The clamp 24025 is mounted on the outside of the crossbeam 2401, slid into the appropriate position, and then fixed to the connecting plate 2403 with bolts. The side panels 24024 are located on both sides of the support plate 24021 and serve to strengthen the support plate 24021. The top plate 24022 is 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 support leg 2402 is limited by the contact between the side panels 24024 and the roof.

[0066] In further design, in order to improve the strength of the legs 2402, as Figure 9 and Figure 12As shown, the support leg 2402 further includes a reinforcing plate 24026 and a locking pin 24027. The reinforcing plate 24026 has a raised portion 26 located on the outside of 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 covered below the bottom plate 24023. The reinforcing plate 24026 has an inserting portion 28 above it that is inserted obliquely upward into the support plate 24021. Figure 9 As shown, the support plate 24021 is tilted outward, and the reinforcement plate 24026 is located on the outside of the support plate 24021, which can prevent the support plate 24021 from bending and deforming. The bottom of the reinforcement plate 24026 is limited by the base plate 24023, and the top is fixed by the plug-in part 28. The upper and lower parts cooperate to achieve the relative fixation of the reinforcement plate 24026 and the support plate 24021. The plug-in part 28 is inserted obliquely upward, and the bending part 27 is bent and covers the base plate 24023. After the assembly is completed, the reinforcement plate 24026 will not be separated from the support plate 24021 at will. 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.
