Description

Technical Field

[0001] The invention relates to the technical field of emergency rescue on tradable road rights, and in particular to a stall buffer emergency control device for vehicles on road rights trading roads. Background Art

[0002] Tradable right-of-way roads introduce the concept of "road rights trading" and are one of the effective solutions to urban traffic congestion caused by the negative externalities of automobile travel. Due to the high-quality travel needs, tradable right-of-way roads need to control access and exit channels, and especially need to be separated from existing free and inclusive roads. Therefore, they will mainly be elevated roads or underground roads. However, the negative impact of elevated roads on the division of urban functions and landscapes leads to greater resistance to their implementation. Therefore, underground roads have become the best implementation method for tradable right-of-way roads.

[0003] However, underground roads have a high efficiency of traffic, and cars are prone to stalling when driving at high speeds, which can cause traffic accidents. In addition, cars may also stall due to malfunctions, so there is a need for control devices for vehicles that stall on the road. Existing emergency devices for car stalls are mostly simple anti-collision barriers (water barriers), which have poor anti-collision effects and are prone to collisions with vehicles behind, causing secondary injuries. Therefore, highways usually use protective slopes as stall emergency measures, but the braking distance required for the protective slopes is long, and they are mostly braked with gravel and their own slopes, and cannot perform fire extinguishing operations. The functions are relatively simple, but the highway protective slopes need to be set up in the open air, otherwise they cannot meet the slope length and slope requirements, so they are not suitable for stall emergency measures on underground roads. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a stall buffer emergency control device for vehicles on road right trading roads, which can effectively perform emergency control on stalled vehicles on underground roads.

[0005] In order to solve the above technical problems, the stall buffer emergency control device for road vehicles in road right trading provided by the present invention adopts the following technical solutions:

[0006] A stall buffer emergency control device for vehicles on a road with road rights trading, comprising an emergency section arranged outside an underground road and intersecting the underground road, the emergency section comprising a deceleration pit assembly and / or a deceleration pavement assembly and a collision buffer assembly arranged in sequence from near to far on the underground road; the deceleration pit assembly comprises a deceleration water pit, the water depth in the deceleration water pit is 0.8-1.5m, and a slope is arranged on the pit wall on the side of the deceleration water pit away from the underground road; the deceleration pavement assembly comprises a deceleration soil pit and clay soil filled in the deceleration soil pit; the collision buffer assembly comprises a fixedly arranged buffer tube body and a piston penetrated and slidably connected to the buffer tube body, the axis of the piston is arranged along the straight line where the emergency section is located, the piston divides the internal space of the buffer tube body into two cavities, and the cavity of the buffer tube body away from the deceleration water pit is filled with water.

[0007] By adopting the above technical solution, when a vehicle stalls while traveling on an underground road, the vehicle can enter the deceleration pit. The buoyancy and resistance of the water body at the above depth can effectively reduce the speed of the vehicle. After deceleration, the vehicle then drives toward the collision buffer assembly through the driving slope. The driving slope reduces the vehicle speed again by converting the vehicle's kinetic energy into potential energy. The vehicle can also enter the deceleration pit and drive over the clay soil. Since the clay soil has more water and a smoother surface, the friction between the tire and the ground is converted into sliding friction, causing the vehicle tire to idle, thereby further reducing the vehicle speed, so that the vehicle is less damaged when it finally hits the piston. Finally, the vehicle hits the piston, pushing the collision piston to compress the water in the buffer tube to do work, releasing kinetic energy, and finally stopping the vehicle in an emergency. By stopping after multiple deceleration processes, the collision damage to the stalled car and the injuries to the people in the car are effectively reduced; and the above structure is adapted to local conditions and cleverly combined with the underground structure to achieve deceleration braking, which is suitable for the control of stall emergency on underground roads, greatly improving the emergency rescue and management level of stall emergency on tradable right-of-way roads.

[0008] Optionally, the bottom wall of the deceleration pit is provided with a plurality of serrated cutting blades.

[0009] By adopting the above technical solution, after the vehicle enters the deceleration puddle, the sawtooth cutting blade will cut the car tire to deflate, so that the vehicle will be further decelerated. At the same time, because the vehicle is in the water at this time, the buoyancy of the water reduces the vehicle's rollover and tail swing caused by tire blowout, so that while decelerating, the vehicle can move forward relatively smoothly.

[0010] Optionally, the emergency section also includes a ground deceleration assembly, which is located between the underground road and the deceleration puddle. The ground deceleration assembly includes a plurality of installation grooves arranged along the straight line where the emergency section is located, and shock-absorbing springs are fixedly installed in the plurality of installation grooves, and speed bumps are fixedly installed on the upper ends of the plurality of shock-absorbing springs.

[0011] By adopting the above technical solution, before entering the deceleration puddle, the vehicle passes through multiple speed bumps with shock-absorbing springs, which can first reduce the speed of the vehicle to a certain extent, so that the damage suffered by the vehicle when it finally hits the piston is smaller; at the same time, the shock-absorbing springs allow the vehicle to move forward in a stable state as much as possible, reducing the risk of the vehicle rolling over during deceleration.

[0012] Optionally, the deceleration pavement assembly includes a deceleration slope connected to the edge of the deceleration pit, the deceleration slope is located on a side of the deceleration pit close to the collision buffer assembly, and the deceleration slope is connected to the collision path of the collision buffer assembly.

[0013] By adopting the above technical solution, the deceleration ramp further converts the kinetic energy of the vehicle into potential energy, further reducing the speed of the vehicle.

[0014] Optionally, a water outlet is provided at the bottom of the buffer tube body, an electric valve is provided at the edge of the water outlet, the water outlet end of the electric valve is connected to a drainage pipe, and the water outlet end of the drainage pipe is close to the collision end of the piston; a pressure sensor is provided at the collision end of the piston, and the pressure sensor is connected to the start control end of the electric valve through a control panel.

[0015] By adopting the above technical solution, when the vehicle hits the piston, it hits the pressure sensor and reaches the set threshold, and the pressure sensor controls the electric valve to open. Since the time for the vehicle to hit the piston to compress the water is very short, the pressure sensor controls the electric valve to open, and the water in the buffer tube that has completed the compression work can be discharged through the drainage pipe to cool the vehicle after stopping.

[0016] Optionally, the underground road is provided with a vehicle sensing module, the vehicle sensing module is connected to an emergency control module via a signal, the emergency control module is connected to a water supply component via a signal, and a nozzle of the water supply component is provided above the deceleration puddle.

[0017] By adopting the above technical solution, when a vehicle stalls while driving on an underground road and reaches the sensing range of the vehicle sensing module, the vehicle sensing module recognizes that the vehicle has stalled, and the vehicle sensing module sends an emergency signal to the emergency control module, which then sends a water spraying signal to the water supply component, and the nozzle above the deceleration water pit starts spraying, so that after the stalled vehicle with a fire enters the deceleration water pit, it can be sprayed and extinguished in a timely and effective manner.

[0018] Optionally, the vehicle sensing module is composed of a sensing high-definition camera, and the sensing high-definition camera has a built-in yolov5 stalled vehicle recognition algorithm.

[0019] Through the above scheme, the vehicle driving posture is calibrated manually on the sample images. The calibration is divided into normal and stalled. The sensing high-definition camera collects video information in real time, and the vehicle driving posture is identified through the yolov5 stall vehicle recognition algorithm. When it is identified as stalled and the result probability is greater than 70%, the vehicle sensing module sends an emergency signal to the emergency control module.

[0020] Optionally, the emergency control module is composed of a CPU, and the CPU is connected to the vehicle sensing module and the water supply component through signals.

[0021] By adopting the above technical solution, after the CPU receives the emergency signal from the vehicle sensing module, it sends a water spraying signal to the water supply component.

[0022] Optionally, a video detection module is provided above the deceleration puddle, and the video detection module can monitor the amount of water in the deceleration puddle in real time.

[0023] By adopting the above technical solution, when the video monitoring module detects that the water volume in the deceleration water pit is lower than the threshold, it sends a water adding signal to the emergency control module, and the emergency control module then sends a water spraying signal to the water supply component. Through the above method, the water volume in the deceleration water pit can be replenished in a timely and effective manner to improve the security of emergency control of stalled vehicles and the convenience of emergency control management.

[0024] Optionally, the video monitoring module is composed of a monitoring high-definition camera, and the monitoring high-definition camera is installed above the deceleration puddle.

[0025] By adopting the above technical solution, the monitoring high-definition camera collects and stores the on-site images of the deceleration puddle in real time. When the management personnel observe through the stored images that the water volume in the deceleration puddle is lower than the set threshold, a water-adding signal is sent to the emergency control module.

[0026] Optionally, the emergency control module is connected to an alarm voice module via a signal, and the alarm voice module includes at least one of a red flashing light, a buzzer and a communication phone.

[0027] By adopting the above technical solution, after the emergency control module receives the emergency signal from the vehicle sensing module, it sends an alarm signal to the red flashing light, buzzer and communication phone, the red flashing light and buzzer are activated, and the communication phone calls the emergency phone to the tradable road emergency management center. The red flashing light, buzzer and communication phone can effectively attract the attention of emergency management personnel and rush to the scene in time to carry out emergency rescue activities. And it can remind other vehicles that there are vehicles in the emergency section, avoiding the situation where subsequent vehicles enter the emergency lane again and collide.

[0028] Optionally, the piston includes a movable column that passes through and is slidably connected to the buffer tube body and a sealing seat that is fixedly connected to one end of the movable column, and the sealing seat is provided with an expansion waterproof rubber ring that abuts against the inner wall of the buffer tube body.

[0029] By adopting the above technical solution, the expansion waterproof rubber ring enables the sealing seat to compress the water in the buffer tube body more stably.

[0030] Optionally, a buffer wall is provided at one end of the buffer tube body close to the deceleration puddle, and the piston is penetrated and slidably connected to the buffer wall; the buffer wall is provided with an auxiliary buffer component, and the auxiliary buffer component is used to buffer the impact on the piston.

[0031] By adopting the above technical solution, the auxiliary buffer component can buffer and disperse the impact force exerted on the piston, thereby releasing a part of the kinetic energy of the vehicle after the collision.

[0032] Optionally, the auxiliary buffer component includes at least two compression springs fixedly connected to the buffer wall and a connecting plate fixed to the at least two buffer springs. The piston is located between the at least two buffer springs. The piston is penetrated and slidably connected to the connecting plate. A collision plate is provided at the end of the piston. The projection of the collision plate along the sliding path of the piston partially overlaps with the connecting plate.

[0033] By adopting the above technical solution, the buffer spring can convert a part of the impact force exerted on the piston into elastic potential energy, so as to effectively buffer the impact.

[0034] Optionally, a resistance spring is provided on the inner wall of the buffer tube body on a side away from the piston.

[0035] By adopting the above technical solution, the resistance spring can further disperse and buffer the impact force exerted on the piston, thereby releasing a part of the kinetic energy after the vehicle collision and avoiding the collision between the piston and the buffer tube body.

[0036] Optionally, the collision plate is fixedly connected with fireproof cotton, which is circular in shape, has a surface coated with yellow fireproof paint and is marked with "collision point" in red font in the center.

[0037] By adopting the above technical solution, the stalled vehicle can more accurately locate the collision point, thereby improving the effectiveness of emergency response.

[0038] Optionally, a warning sign is also included, and the warning sign is used to indicate the distance between the vehicle and the entrance of the emergency section.

[0039] By adopting the above technical solution, the stalled vehicle can prepare to enter the emergency section in advance, and avoid the stalled vehicle missing the nearest emergency section.

[0042] By adopting the above technical solution, if the stalled vehicle deviates from its route due to difficulty in controlling the steering wheel during the deceleration process, it will collide with the underground structure next to it. The anti-collision water barriers will protect the stalled vehicle to reduce the damage caused by side collisions or scratches to the stalled vehicle.

[0043] In summary, the present invention includes at least one of the following beneficial technical effects:

[0044] 1. The vehicle is stopped after multiple deceleration processes, which effectively reduces the collision damage to the stalled vehicle and the injuries to the people in the vehicle. In addition, the above structure is adapted to local conditions and cleverly combines the underground structure to achieve deceleration and braking, which is suitable for the control of stall emergency on underground roads, greatly improving the emergency rescue and management level of stall emergency on underground roads with tradable road rights.

DETAILED DESCRIPTION

[0051] The following is combined with Figure 1-3 The present invention is described in further detail.

[0052] The embodiment of the present invention discloses a stall buffer emergency control device for vehicles on a road with road rights trading. Figure 1 and Figure 2 The road right trading road vehicle stall buffer emergency control device includes an emergency section arranged outside the underground road and intersecting with the underground road, the emergency section includes a ground deceleration component 1, a deceleration pit component 2, a deceleration pavement component 3 and a collision buffer component 4, and the ground deceleration component 1, the deceleration pit component 2, the deceleration pavement component 3 and the collision buffer component 4 are arranged in sequence from near to far on one side of the underground road and are arranged in a straight line.

[0053] Reference Figure 2 The ground deceleration assembly 1 includes a plurality of mounting grooves, which are opened on the ground and arranged along the straight line where the emergency section is located. The length direction of the mounting grooves is perpendicular to the straight line where the emergency section is located, and the opening direction of the mounting grooves is vertically upward. The bottom walls of the plurality of mounting grooves are fixedly connected with shock absorbing springs, the expansion and contraction direction of the shock absorbing springs is vertically arranged, and the length of the shock absorbing springs in a normal state is greater than the depth of the mounting grooves. The upper end of the shock absorbing spring is fixedly connected with a speed bump, and the length direction of the speed bump is parallel to the mounting groove.

[0054] Reference Figure 2 The deceleration pit assembly 2 includes a deceleration pit 21, the depth of the deceleration pit 21 is 1.5m, and the deceleration pit 21 is filled with water, the water depth is 1m. The pit walls of the deceleration pit 21 close to the underground road and away from the underground road are both provided with slopes. The bottom wall of the deceleration pit 21 is fixedly connected with a plurality of serrated cutting blades 22, and the plurality of serrated cutting blades 22 are arranged at intervals along the straight line where the emergency section is located, and the lengths of the plurality of serrated cutting blades 22 are perpendicular to the straight line where the emergency section is located. The serrated cutting blades 22 are made of hard steel and are 1m long.

[0055] Reference Figure 2 The deceleration road surface assembly 3 includes a deceleration pit 31, cohesive soil 32 and a deceleration slope 33. The deceleration pit 31 is a rectangular pit. The length of one side of the deceleration pit 31 parallel to the straight line where the emergency section is located is 2m. The cohesive soil 32 is filled in the deceleration pit 31. The cohesive soil 32 is silty soil with a natural porosity ratio of 1.0-1.5. In the embodiment of the present application, the natural porosity ratio of the cohesive soil 32 is 1.2. The lower end of the deceleration slope 33 is connected to the edge of one side of the deceleration pit 31 away from the deceleration water pit 21. The deceleration slope 33 is a slope with an inclination angle of 30°, and the slope length of the deceleration slope 33 is 2m.

[0056] Reference Figure 2 The collision buffer assembly 4 includes a buffer tube body 41 and a piston. The two ends of the buffer tube body 41 are closed. The buffer tube body 41 is fixedly connected to the underground structure. The buffer tube body 41 is adjacent to the upper end of the deceleration ramp 33. The length direction of the buffer tube body 41 is parallel to the straight line where the emergency section is located. The piston includes a movable column 421 and a blocking seat 422. The movable column 421 is penetrated and slidably connected to the buffer tube body 41. The sliding path of the movable column 421 is parallel to the emergency path. The blocking seat 422 is fixedly connected to one end of the movable column 421 located in the buffer tube body 41. An expansion waterproof rubber ring is provided on the outer edge of the blocking seat 422, and the expansion waterproof rubber ring abuts against the inner wall of the buffer tube body 41. The blocking seat 422 and the expansion waterproof rubber ring divide the internal space of the buffer tube body 41 into two cavities, and the cavity of the buffer tube body 41 away from the movable column 421 is filled with water. A resisting spring 7 is disposed on the inner wall of the buffer tube body 41 away from the movable column 421 . The extension and contraction direction of the resisting spring 7 is parallel to the axis of the buffer tube body 41 .

[0057] When a vehicle running on an underground road stalls, the vehicle can enter the emergency section. The vehicle first passes through a plurality of speed bumps with shock-absorbing springs, which can reduce the speed of the vehicle to a certain extent, so that the vehicle will suffer less damage when it finally hits the piston; at the same time, the shock-absorbing springs make the vehicle move forward in a stable state as much as possible, reducing the risk of the vehicle rolling over during deceleration. Then the vehicle enters the deceleration puddle 21. The buoyancy and resistance of the water body at the above depth can effectively reduce the speed of the vehicle. At the same time, the sawtooth cutting blade 22 will cut the car tire to deflate, so that the vehicle will further decelerate. And because the vehicle is in the water at this time, the buoyancy of the water reduces the vehicle's rollover and tail swing caused by a tire blowout, so that while decelerating, the vehicle is guaranteed to move forward relatively smoothly.

[0058] After deceleration, the vehicle drives toward the deceleration pit 31 through the driving slope. The driving slope reduces the vehicle speed again by converting the vehicle's kinetic energy into potential energy. The vehicle enters the deceleration pit 31 and drives over the clay soil 32. Since the clay soil 32 has a lot of water and a smooth surface, the friction between the tires and the ground is converted into sliding friction, causing the vehicle tires to idle, thereby further reducing the vehicle speed and causing less damage to the vehicle when it finally hits the piston. The deceleration slope 33 further converts the vehicle's kinetic energy into potential energy, further reducing the vehicle speed. Finally, the vehicle hits the movable rod, pushing the collision piston to compress the water in the buffer tube body 41 to do work, releasing kinetic energy, and finally stopping the vehicle in an emergency. The resistance spring 7 can further disperse and buffer the impact force on the piston, thereby releasing part of the kinetic energy of the vehicle after the collision, and preventing the piston from colliding with the buffer tube body 41.

[0059] By going through multiple deceleration processes and then stopping the vehicle, the collision damage to the stalled vehicle and the injuries to the people in the vehicle are effectively reduced. In addition, the above-mentioned structure is adapted to local conditions and cleverly combines with underground structures to achieve deceleration and braking, which is suitable for emergency control of stalls on underground roads, greatly improving the level of emergency rescue and management of stalls on underground roads with tradable road rights.

[0060] Reference Figure 2 In order to cool down the vehicle that is stopped by the collision with the piston, a water outlet is provided at the bottom of the buffer tube body 41, and an electric valve 8 is provided at the edge of the water outlet. The water outlet end of the electric valve 8 is connected to a drainage pipe 9, which is made of PVC. The water outlet end of the drainage pipe 9 is close to the collision end of the piston. A pressure sensor is provided at the collision end of the piston, and the pressure sensor is connected to the start control end of the electric valve 8 through a control board.

[0061] When the vehicle hits the piston, it hits the pressure sensor and reaches the set threshold, and the pressure sensor controls the electric valve 8 to open. Since the time for the vehicle to hit the piston to compress the water body is very short, the pressure sensor controls the electric valve 8 to open, and the water in the buffer tube 41 that has completed the compression work can be discharged through the drainage pipe 9 to cool the vehicle after stopping.

[0062] Reference Figure 2 In order to make the vehicle stop more smoothly after hitting the piston, the end of the buffer pipe body close to the deceleration puddle is fixedly connected to the buffer wall 5, and the buffer wall 5 is perpendicular to the straight line where the emergency section is located. The drainage pipe 9 is penetrated through the buffer wall 5, and the water outlet end of the drainage pipe 9 is located below the movable column 421.

[0063] Reference Figure 2The buffer wall 5 is provided with an auxiliary buffer member 6, which includes two compression springs and a connecting plate 62. The two compression springs are fixedly connected to the side wall of the buffer wall 5 away from the buffer tube 41. The expansion and contraction directions of the two compression springs are perpendicular to the buffer wall 5. The ends of the two buffer springs 61 away from the buffer wall 5 are fixedly connected to the connecting plate 62. The movable column 142 is located between the two buffer springs 61. The movable column 421 is penetrated and slidably connected to the connecting plate 62. The end of the movable column 421 away from the buffer tube 41 is vertically fixed with a collision plate 4211. The collision plate 4211 is a rectangular metal plate. The projection of the collision plate 4211 along the piston sliding path partially overlaps with the connecting plate 62.

[0064] The vehicle hits the collision plate 4211, and the collision plate 4211 hits the connecting plate 62 and squeezes the buffer spring 61. The buffer spring 61 can convert a part of the impact force received by the piston into elastic potential energy to effectively buffer the impact, and buffer and disperse the impact force received by the piston, thereby releasing a part of the kinetic energy of the vehicle after the collision, so as to more smoothly stop the vehicle in an emergency.

[0065] Reference Figure 2 In order to enable the vehicle to more accurately locate the collision point, a fireproof cotton is fixedly connected to the side wall of the collision plate 4211 away from the movable column 421. The fireproof cotton is round, and the surface of the fireproof cotton is coated with yellow fireproof paint and the center is marked with "collision point" in red font, so that the stalled vehicle can more accurately locate the collision point, thereby improving the effectiveness of emergency response.

[0066] In order to enable stalled vehicles to enter the emergency section in time, warning signs are set up next to the underground road near the entrance of the emergency section. The warning signs include multiple red-letter signs with a blue background. The multiple red-letter signs with a blue background are arranged at 10m, 50m, 100m, 150m and 200m away from the entrance of the emergency section. The multiple red-letter signs with a blue background are set on the right side of the underground road wall through an embedded structure. The warning signs enable stalled vehicles to find the entrance of the emergency section in advance and prepare to enter the emergency section, and prevent stalled vehicles from missing the nearest emergency section.

[0067] In order to reduce the damage caused by side collision or scraping of the stalled vehicle during deceleration on the emergency road section, an outer protective part is set on the emergency road section, which includes multiple anti-collision water barriers, which are arranged in a row on both sides of the emergency road section and filled with water. If the stalled vehicle deviates from the route due to difficulty in controlling the steering wheel during deceleration, it will collide with the underground structure next to it. The anti-collision water barriers protect the stalled vehicle to reduce the damage caused by side collision or scraping of the stalled vehicle.

[0068] Reference Figure 3,Since some stalled vehicles may catch fire at the same time as stalling, a vehicle sensing module is installed in the underground road near the entrance of the emergency section. The vehicle sensing module is connected to the emergency control module through signals. The vehicle sensing module is composed of a sensing high-definition camera, which has a built-in yolov5 stalled vehicle recognition algorithm. The vehicle driving posture is calibrated manually on the sample image. The calibration is divided into normal and stalled. The high-definition camera collects video information in real time and identifies the vehicle driving posture through the yolov5 stalled vehicle recognition algorithm. When it is identified as stalled and the result probability is greater than 70%, the vehicle sensing module sends an emergency signal to the emergency control module.

[0069] Reference Figure 3 The emergency control module is composed of a CPU, the vehicle sensing module is connected to the CPU through signals, the CPU is connected to a water supply component through signals, and the nozzle of the water supply component is set above the deceleration pit 21. When a vehicle stalls while driving on an underground road and reaches the sensing range of the vehicle sensing module, the vehicle sensing module recognizes that the vehicle has stalled, and the vehicle sensing module sends an emergency signal to the emergency control module, and the emergency control module sends a water spraying signal to the water supply component, and the nozzle above the deceleration pit 21 starts spraying, so that after the stalled vehicle with a fire enters the deceleration pit 21, it can be sprayed and extinguished in time and effectively.

[0070] The amount of water in the deceleration puddle 21 will gradually decrease due to evaporation or vehicles driving by and taking away some of the water. A video detection module is arranged above the deceleration puddle 21, and the video monitoring module is composed of a monitoring high-definition camera, which is installed above the deceleration puddle 21.

[0071] Reference Figure 3 The video monitoring module collects and stores the on-site images of the deceleration pit 21 in real time. When the manager observes through the stored images that the water volume of the deceleration pit 21 is lower than the set threshold, a water-adding signal is sent to the CPU, and the emergency control module sends a water-spraying signal to the water supply component. Through the above method, the water volume in the deceleration pit 21 can be replenished in a timely and effective manner to improve the security of the emergency control of the stalled vehicle and the convenience of emergency control management.

[0072] Reference Figure 3 In order to enable emergency management personnel to carry out rescue work on stalled vehicles more promptly, the emergency control module is connected to the alarm voice module through signals. The alarm voice module includes a red flashing light, a buzzer and a communication phone. The emergency control module is also connected to the red flashing light, the buzzer and the communication phone through signals.

[0073] After receiving the emergency signal from the vehicle sensing module, the emergency control module sends an alarm signal to the red flashing light, buzzer and communication phone. The red flashing light and buzzer are activated, and the communication phone calls the emergency phone to the tradable road emergency management center. The red flashing light, buzzer and communication phone can effectively attract the attention of emergency management personnel and rush to the scene in time to carry out rescue activities. And it can remind other vehicles that there are vehicles in the emergency section to avoid the situation where subsequent vehicles enter the emergency lane again and collide.

[0074] The implementation principle of a stall buffer emergency control device for road vehicles on a road right trading road in an embodiment of the present invention is as follows: when a vehicle running on an underground road stalls, the vehicle can enter the emergency section, and the vehicle first passes through a plurality of speed bumps to reduce the speed of the vehicle to a certain extent. Then the vehicle enters the deceleration pit 21, and the buoyancy and resistance of the water body at the above depth can effectively reduce the speed of the vehicle. At the same time, the sawtooth cutting blade 22 cuts the car tire to deflate, so that the vehicle is further decelerated. The decelerated vehicle then drives toward the deceleration pit 31 through the driving slope, and the driving slope reduces the vehicle speed again by converting the vehicle's kinetic energy into potential energy. The vehicle enters the deceleration pit 31 and drives through the clay soil 32 to further reduce the vehicle speed, so that the vehicle suffers less damage when it finally hits the piston. Finally, the vehicle hits the movable rod, pushing the collision piston to compress the water body in the buffer tube body 41 to do work, release kinetic energy, and finally make the vehicle emergency stop.

[0075] By going through multiple deceleration processes and then stopping the vehicle, the collision damage to the stalled vehicle and the injuries to the people in the vehicle are effectively reduced.
