After the vehicle three-dimensional model stops moving, the phenomenon of the vehicle blocking the road can be simulated, so that the observer can more intuitively understand the situation of the vehicle blocking the road; By pulling up the support, the plug block and the card block move upward. After the card block moves to the top of the protrusion, the plug block and the card block can be pulled out from the slots on the side walls of the positioning seat, and the vehicle three-dimensional model can be replaced. By replacing the three-dimensional models of vehicles of different models, the observer can intuitively understand the situation when vehicles of different specifications block the road.

[0011] In a specific embodiment, the support is a corner plate, and the upper end surface of the positioning seat is in contact with the inner top end of the support.

[0012] In the above implementation process, the fitting arrangement enables the positioning seat and the support to be connected more tightly.

[0013] In a specific implementation, the card block is an iron block, a magnetic body is installed inside the slot, and the card block and the magnetic body attract each other.

[0014] In the above implementation process, the card block can be installed in the slot more stably under the effect of magnetic attraction.

[0015] In a specific embodiment, the height of the magnetic body is not greater than the height of the protrusion.

[0016] In a specific embodiment, the upper end surface of the magnetic body and the lower end surface of the block are in contact with each other.

[0017] In the above implementation process, the fitting arrangement can make the card block better adsorbed on the upper end surface of the magnetic body.

[0018] In a specific implementation, the cross section of the three-dimensional road model is cross-shaped, support plates are installed at the four inner corners of the base, and the support plates are fixedly connected to the three-dimensional road model.

[0019] In the above implementation process, a support plate is provided to support the three-dimensional road model, so that the three-dimensional road model can be erected more stably.

[0020] In a specific embodiment, a bearing seat is installed on the lower end surface of the support plate, and the end of the screw rod is rotatably connected to the bearing seat.

[0021] In the above implementation process, a bearing seat is provided to support the screw rod, which is more conducive to the rotation installation of the screw rod.

[0022] In a specific implementation manner, the bearing seats are arranged opposite to each other in pairs, and the two corresponding bearing seats are respectively located at two ends of the screw rod.

[0023] In the above implementation process, two bearing seats are provided to better support the screw rod.

[0024] In a specific embodiment, at least two of the sliding blocks are spaced apart in the groove of the slide slot, and ring bodies are installed on both sides of the sliding block, and a connector is provided between two adjacent ring bodies.

[0025] In the above implementation process, multiple sliders are set, and positioning seats can be set on the surfaces of multiple sliders, so that vehicle three-dimensional models can be installed above multiple sliders. Multiple vehicle three-dimensional models are simultaneously set on the surface of the road three-dimensional model, which can simulate the situation where multiple vehicles block the road. When one of the sliders moves, it will move the remaining sliders under the drive of the connector, so that multiple vehicle three-dimensional models can be moved on the surface of the road three-dimensional model, which can simulate the phenomenon of multiple vehicles moving on the road surface.

[0026] In a specific embodiment, the connector includes two hooks, and the two hooks are respectively hung on the surfaces of the corresponding ring bodies, screws are installed on opposite sides of the two hooks, and the shafts of the screws are threadedly sleeved with screw sleeves, rotating bodies are rotatably installed on opposite sides of the two screw sleeves, and a spring is fixed between the two rotating bodies.

[0027] In the above implementation process, the length of the connector can be changed by rotating the screw sleeve to move the screw sleeve on the rod body, and the two adjacent vehicle three-dimensional models are connected by a connector with adjustable length. By changing the length of the connector, it can adapt to vehicle three-dimensional models of different specifications, and has stronger versatility.

[0028] In a specific implementation scheme, a telescopic part is installed on the lower end surface of the road three-dimensional model, a push block is installed in the groove of the slide groove, and the push block is fixedly connected to the movable end of the telescopic part, and the side wall of the push block is provided with a groove corresponding to the ring body.

[0029] In the above implementation process, when the screw block stops moving, the slider connected to the screw block will stop moving, and the telescopic part will be adjusted so that the movable end of the telescopic part drives the push block to move. After the push block contacts the ring body on the surface of other sliders, it will push the other sliders to move, and the spring in the connector will expand and contract, which can change the distance between two adjacent vehicle three-dimensional models. After the distance between two adjacent vehicle three-dimensional models is reduced, it is more conducive to simulating the situation where vehicles block the road.

[0030] In a specific embodiment, the screw block is fixedly connected to only one of the sliding blocks.

[0031] In the above implementation process, when the screw block moves, it can drive one of the sliders to move.

[0033] In the above implementation process, the bolt is rotated to support the movement of the friction plate until one side of the friction plate is close to the inner wall of the slide groove, so that the limit seat can be fixed. When the slider moves, the limit seat can hinder the movement of the slider, thereby limiting the movement of the vehicle's three-dimensional model, which can effectively avoid excessive movement of the vehicle's three-dimensional model and improve the demonstration effect.

[0034] In a specific implementation, a connecting plate is installed on the lower end surface of the limit seat, and a telescopic cylinder is installed on the side wall of the connecting plate. A limiting column is installed on the movable end of the telescopic cylinder, and the top end of the limiting column is slidably inserted into the notch on the surface of the limit seat.

[0035] In the above implementation process, after the ring body of the slider side wall is inserted into the notch of the limit seat side wall, the telescopic cylinder is adjusted, and the movable end of the telescopic cylinder drives the limit column to move upward, so that the limit column can be inserted into the ring body to fix the ring body, thereby fixing the slider and the vehicle three-dimensional model, which can effectively prevent the vehicle three-dimensional model from moving when demonstrating road congestion.

[0036] The telescopic member and the telescopic cylinder are any one of a pneumatic cylinder, an electric cylinder, an electric push rod and a hydraulic cylinder.

[0037] In a specific implementation manner, anti-slip grooves are engraved on opposite sides of the two friction plates.

[0038] In the above implementation process, the provision of the anti-skid pattern can improve the braking effect of the friction plate.

[0039] Beneficial effects: The present application provides a three-dimensional display model of a digital traffic congestion section, which simulates the phenomenon of vehicles running on the road surface and blocking the road through the cooperation of the vehicle three-dimensional model and the road three-dimensional model. With the cooperation of the support and the positioning seat, the vehicle three-dimensional model connected to the slider can be replaced. By replacing the three-dimensional models of vehicles of different models, the observer can intuitively understand the situation when vehicles of different specifications block the road.

[0040] When a road is blocked, it is usually caused by multiple vehicles on the same lane, but it is inconvenient to set multiple vehicle models on the surface of the road model in the model display equipment, which is not conducive to display.

[0041] A plurality of sliders are provided, and positioning seats can be provided on the surfaces of the plurality of sliders, so that a vehicle three-dimensional model can be installed on the top of the plurality of sliders. The plurality of vehicle three-dimensional models are simultaneously provided on the surface of the road three-dimensional model, so that a situation where multiple vehicles block the road can be simulated. When one of the sliders moves, the remaining sliders are moved under the drive of the connector, so that the plurality of vehicle three-dimensional models can be moved on the surface of the road three-dimensional model, so that the phenomenon of multiple vehicles moving on the road surface can be simulated. By rotating the screw sleeve to move the screw sleeve on the rod of the screw, the length of the connector can be changed. Two adjacent three-dimensional vehicle models are connected by a connector with adjustable length. By changing the length of the connector, it can be adapted to three-dimensional vehicle models of different specifications, and has stronger versatility. When the screw block stops moving, the slider connected to the screw block will stop moving, and the telescopic part will be adjusted so that the movable end of the telescopic part will drive the push block to move. After the push block contacts the ring body on the surface of other sliders, it will push the other sliders to move, and the spring in the connector will expand and contract, which can change the distance between two adjacent vehicle three-dimensional models. After the distance between two adjacent vehicle three-dimensional models is reduced, it is more conducive to simulating the situation where vehicles block the road.

[0042] When demonstrating a vehicle blocking a road, the vehicle model needs a moving door on the surface of the road model. After the vehicle model moves to a predetermined position, it needs to stop moving. However, the vehicle model is prone to excessive movement due to inertia, which affects the demonstration effect.

[0043] In the above implementation process, by rotating the bolt, the friction plate supported by the bolt moves until one side of the friction plate is close to the inner wall of the slide groove, the limit seat can be fixed, and when the slider moves, the limit seat can hinder the movement of the slider, thereby limiting the movement of the vehicle three-dimensional model, which can effectively avoid excessive movement of the vehicle three-dimensional model and improve the demonstration effect; After the ring body of the side wall of the slider is inserted into the notch of the side wall of the limit seat, the telescopic cylinder is adjusted, and the movable end of the telescopic cylinder drives the limit column to move upward, so that the limit column can be inserted into the inside of the ring body to fix the ring body, thereby fixing the slider and the vehicle three-dimensional model, which can effectively prevent the vehicle three-dimensional model from moving when demonstrating road congestion.

[0054] In the above implementation process, the vehicle three-dimensional model 200 can simulate the blocked situation at the intersection on the surface of the road three-dimensional model 110 for the observer to view.

[0055] In a specific embodiment, the support 210 is a corner plate, and the upper end surface of the positioning seat 140 is in contact with the inner top end of the support 210 .

[0057] In a specific implementation, the block 230 is an iron block, a magnetic body 151 is installed inside the slot 150, and the block 230 and the magnetic body 151 attract each other.

[0058] In the above implementation process, under the effect of magnetic attraction, the card block 230 can be installed in the slot 150 more stably.

[0059] In a specific embodiment, the height of the magnetic body 151 is not greater than the height of the protrusion 160 .

[0060] In a specific implementation, the upper end surface of the magnetic body 151 and the lower end surface of the block 230 are in contact with each other.

[0064] In a specific implementation, a bearing seat 171 is installed on the lower end surface of the support plate 170 , and the end of the screw rod 310 is rotatably connected to the bearing seat 171 .

[0065] In the above implementation process, a bearing seat 171 is provided to support the screw rod 310 , which is more conducive to the rotation installation of the screw rod 310 .

[0066] In a specific implementation, the bearing seats 171 are arranged opposite to each other in pairs, and the two corresponding bearing seats 171 are respectively located at the two ends of the screw rod 310.

[0067] In the above implementation process, two bearing seats 171 are provided to better support the screw rod 310 .

[0068] When a road is blocked, it is usually caused by multiple vehicles on the same lane, but it is inconvenient to set multiple vehicle models on the surface of the road model in the model display equipment, which is not conducive to display.

[0069] In a specific implementation, at least two sliders 130 are arranged in the groove of the slide groove 120 at intervals, and ring bodies 400 are installed on both sides of the slider 130, and a connector 410 is arranged between two adjacent ring bodies 400.

[0070] In the above implementation process, multiple sliders 130 are set, and positioning seats 140 can be set on the surfaces of multiple sliders 130, so that vehicle three-dimensional models 200 can be installed above multiple sliders 130. Multiple vehicle three-dimensional models 200 are simultaneously set on the surface of the road three-dimensional model 110, which can simulate the situation where multiple vehicles block the road. When one of the sliders 130 is moving, it will be driven by the connector 410 to move the remaining sliders 130, so that multiple vehicle three-dimensional models 200 can be moved on the surface of the road three-dimensional model 110, which can simulate the phenomenon of multiple vehicles moving on the road surface.

[0071] In a specific implementation scheme, the connector 410 includes two hooks 411, and the two hooks 411 are respectively hung on the surfaces of the corresponding ring body 400, screws 412 are installed on the opposite sides of the two hooks 411, and the shaft of the screw 412 is threadedly sleeved with a screw sleeve 413, and rotating bodies 414 are rotatably installed on the opposite sides of the two screw sleeves 413, and a spring 415 is fixed between the two rotating bodies 414.

[0072] In the above implementation process, by rotating the screw sleeve 413 to move the screw sleeve 413 on the rod body of the screw rod 412, the length of the connector 410 can be changed, and two adjacent vehicle three-dimensional models 200 are connected by a connector 410 with adjustable length. By changing the length of the connector 410, it can be adapted to vehicle three-dimensional models 200 of different specifications, and has stronger versatility.

[0073] In a specific implementation scheme, a telescopic part 420 is installed on the lower end surface of the road three-dimensional model 110, a push block 430 is installed in the groove of the slide groove 120, and the push block 430 is fixedly connected to the movable end of the telescopic part 420, and the side wall of the push block 430 is provided with a groove corresponding to the ring body 400.

[0074] In the above implementation process, when the screw block 320 stops moving, the slider 130 connected to the screw block 320 will stop moving, and the telescopic member 420 will be adjusted so that the movable end of the telescopic member 420 drives the push block 430 to move. After the push block 430 contacts the ring body 400 on the surface of other sliders 130, it will push the other sliders 130 to move, and the spring 415 in the connecting body 410 will expand and contract, which can change the distance between two adjacent vehicle three-dimensional models 200. After the distance between two adjacent vehicle three-dimensional models 200 is reduced, it is more conducive to simulating the situation where vehicles block the road.

[0075] In a specific embodiment, the screw block 320 is fixedly connected to only one of the sliding blocks 130 .

[0076] In the above implementation process, the screw block 320 can drive one of the sliders 130 to move when it moves.

[0077] When demonstrating a vehicle blocking a road, the vehicle model needs a moving door on the surface of the road model. After the vehicle model moves to a predetermined position, it needs to stop moving. However, the vehicle model is prone to excessive movement due to inertia, which affects the demonstration effect.

[0078] In a specific implementation scheme, a limit seat 500 is slidably installed inside the slide groove 120, and a notch corresponding to the ring body 400 is opened on one side of the limit seat 500, and two protruding plates 510 are arranged on the other side of the limit seat 500, and the surfaces of the two protruding plates 510 are threadedly installed with bolts 520, and the two bolts 520 are symmetrically arranged, and friction plates 530 are installed on the opposite sides of the two bolts 520, and the opposite sides of the two friction plates 530 are both close to the inner wall of the slide groove 120.

[0079] In the above implementation process, by rotating the bolt 520, the bolt 520 supports the friction plate 530 to move until one side of the friction plate 530 is close to the inner wall of the slide groove 120, and the limit seat 500 can be fixed. When the slider 130 moves, the limit seat 500 can hinder the movement of the slider 130, thereby limiting the movement of the vehicle three-dimensional model 200, which can effectively avoid excessive movement of the vehicle three-dimensional model 200 and improve the demonstration effect.

[0080] In a specific implementation scheme, a connecting plate 540 is installed on the lower end surface of the limit seat 500, and a telescopic cylinder 550 is installed on the side wall of the connecting plate 540. A limiting column 560 is installed on the movable end of the telescopic cylinder 550, and the top end of the limiting column 560 is slidably inserted into the notch on the surface of the limit seat 500.

[0081] In the above implementation process, after the ring body 400 on the side wall of the slider 130 is inserted into the notch on the side wall of the limit seat 500, the telescopic cylinder 550 is adjusted, and the movable end of the telescopic cylinder 550 drives the limit column 560 to move upward, so that the limit column 560 can be inserted into the inside of the ring body 400 to fix the ring body 400, thereby fixing the slider 130 and the vehicle three-dimensional model 200, which can effectively prevent the vehicle three-dimensional model 200 from moving when demonstrating road congestion.

[0082] The telescopic member 420 and the telescopic cylinder 550 are any one of a pneumatic cylinder, an electric cylinder, an electric push rod and a hydraulic cylinder.

[0083] In a specific embodiment, anti-slip grooves are engraved on opposite sides of the two friction plates 530 .

[0084] In the above implementation process, the provision of the anti-skid pattern can improve the braking effect of the friction plate 530 .

[0085] Specifically, when the digital traffic congestion road section three-dimensional display model is used, the motor 300 is started, the motor 300 drives the screw rod 310 to rotate, and the screw block 320 threadedly connected to the rod body of the screw rod 310 drives the slider 130 to move in the groove of the slide groove 120, so that the vehicle three-dimensional model 200 moves in the road three-dimensional model 110, simulating the vehicle driving on the road surface, and when the vehicle three-dimensional model 200 moves to the intersection of the road three-dimensional model 110, after the motor 300 is stopped, the vehicle three-dimensional model 200 stops moving, and the phenomenon of vehicles blocking the road intersection can be simulated, so that the observer can more intuitively understand the situation of vehicles blocking the road; By pulling up the support 210, the insert block 220 and the clamp block 230 move upward. After the clamp block 230 moves to the top of the protrusion 160, the insert block 220 and the clamp block 230 can be pulled out from the slot 150 on the side wall of the positioning seat 140, and the vehicle three-dimensional model 200 can be replaced. By replacing the vehicle three-dimensional model 200 of different models, the observer can intuitively understand the situation when vehicles of different specifications block the road.
