Description

Technical Field

[0001] The invention relates to the technical field of urban traffic emergency response, and in particular to an emergency placement system based on urban traffic. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] In urban traffic, especially road traffic, emergencies often occur, usually caused by vehicle breakdowns or traffic accidents. Therefore, most roads are equipped with emergency lanes to facilitate emergency parking or emergency placement.

[0004] However, the road emergency lane in the related technology is relatively simple, using lines to divide the normal road and the emergency road. Vehicles that break down or have traffic accidents are often out of control. After the car enters the road emergency lane only through the driver's emergency braking, it may collide with the curb or run off the road due to its high speed, causing serious secondary traffic accidents. Summary of the invention

[0005] The purpose of the present invention is to provide an emergency placement system based on urban traffic, which adopts a sand pit type vehicle deceleration structure and a speed bump type vehicle deceleration structure to perform multi-stage deceleration on vehicles to avoid secondary traffic accidents or reduce the intensity of secondary traffic accidents.

[0020] As a further optimization scheme, in order to elastically buffer the impact after being squeezed, and to make the piston plate move downward in the rectangular groove body through deformation, so as to squeeze the air at the lower end of the inner cavity of the sand pit type vehicle deceleration structure into the lower end of the inner cavity of the speed reduction belt type vehicle deceleration structure, the elastic support frame includes:

[0021] Lower support columns, the bottom surface of the rectangular trough is evenly fixed with lower support columns;

[0024] The upper end of the upper support column abuts against the bottom surface of the piston plate.

[0025] As a further optimization scheme, in order to lift the rectangular plate by airflow to drive the upper end of the longitudinal strip plate to pass through the strip window, the longitudinal strip plate extending from the upper surface of the emergency lane of the road is used to block and hinder the forward movement of the wheels, the speed reduction belt type vehicle deceleration structure includes:

[0026] A rectangular frame is longitudinally embedded and assembled on the upper surface of the emergency lane of the road close to the curb;

[0027] Limit blocks are symmetrically fixedly assembled on the left and right sides of the inner cavity of the rectangular frame;

[0028] A rectangular plate is slidably assembled in a sealed manner in the rectangular frame;

[0029] The bottom surface of the rectangular plate abuts against the upper ends of the limit blocks on both sides;

[0030] The upper surface of the rectangular plate is evenly and detachably assembled with longitudinal strip plates along the width direction;

[0031] A strip window is provided on the top surface of the rectangular frame body corresponding to the longitudinal strip plate, and the upper end of the longitudinal strip plate is inserted into the corresponding strip window.

[0032] As a further optimization scheme, in order to transmit a signal to the controller after the pressure sensor is squeezed, and use the controller to control the movable part of the lifting and intercepting structure of the adjacent vehicle at the rear side to extend out of the upper surface of the emergency lane of the road to warn and intercept the wheels of the rear vehicle, the upper end of the longitudinal strip plate is evenly embedded with pressure sensors along the length direction;

[0033] The vehicle lifting and intercepting structure is laterally mounted on the upper surface of the road emergency lane, and the vehicle lifting and intercepting structure and the speed reduction belt type vehicle deceleration structure are spaced apart;

[0042] The slope surface is evenly embedded with LED lights along the length direction, and the LED lights are electrically connected to the controller after being connected in parallel.

[0045] A second rigid spring is sleeved on the outer wall of the second guide rod, and two ends of the second rigid spring are respectively against the curb and the side wall of the elastic rubber plate.

[0046] As a further optimization scheme, in order to improve the wear resistance of the outer wall of the elastic rubber plate close to the road emergency lane, a wear-resistant layer is adhered and fixed to the side wall of the elastic rubber plate close to the road emergency lane.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] See also Figure 1-Figure 9 The present invention provides a technical solution: an emergency placement system based on urban traffic, comprising a road emergency lane 1 and a curb 2 arranged on a side of the road emergency lane 1 away from the road.

[0065] The road emergency lane 1 is evenly equipped with vehicle emergency deceleration components along the length direction, which include:

[0066] A sand pit type vehicle speed reduction structure 3 and a speed reduction belt type vehicle speed reduction structure 4;

[0067] The sand pit type vehicle speed reduction structure 3 and the speed reduction belt type vehicle speed reduction structure 4 are embedded and assembled on the upper surface of the road emergency lane 1 along the width direction, and the speed reduction belt type vehicle speed reduction structure 4 is located on the side close to the curb 2;

[0068] The lower ends of the sand pit type vehicle deceleration structure 3 and the speed bump type vehicle deceleration structure 4 are evenly fixed and connected with a ventilation pipe 7;

[0069] After the sand pit type vehicle deceleration structure 3 is compressed by the vehicle wheels, the gas enters the speed reduction belt type vehicle deceleration structure 4 along the ventilation pipe 7, and the air intake in the speed reduction belt type vehicle deceleration structure 4 lifts up its active part and extends out of the upper surface of the road emergency lane 1 to hinder the vehicle wheels from moving forward.

[0070] Specifically in this embodiment, the sand pit type vehicle speed reduction structure 3 and the speed bump type vehicle speed reduction structure 4 are longitudinally distributed on the left and right sides of the upper surface of the road emergency lane 1, and the sand pit type vehicle speed reduction structure 3 and the speed bump type vehicle speed reduction structure 4 have a speed reduction effect on the passing vehicles;

[0071] Furthermore, the extruded sand pit type vehicle deceleration structure 3 and the speed reduction belt type vehicle deceleration structure 4 adopt two different deceleration modes, and other types of deceleration structures may be used to replace the sand pit type vehicle deceleration structure 3 and the speed reduction belt type vehicle deceleration structure 4, for example, an uneven road surface structure, a road surface structure with a slope, a road surface paved with a sand layer, etc.;

[0072] More specifically, the wheel first squeezes the sand pit type vehicle deceleration structure 3 to compress the space at its lower end, and the air inside it is discharged into the lower end of the inner cavity of the speed bump type vehicle deceleration structure 4, and the air intake lifts up its active part to extend out of the upper surface of the road emergency lane 1 to hinder the vehicle wheels from moving forward, so that the sand pit type vehicle deceleration structure 3 and the speed bump type vehicle deceleration structure 4 achieve a linkage effect;

[0073] It can be understood that during the movement of the vehicle, the gas in the lower end space of the two flows according to the pressure change of the corresponding structure, and when the wheel only squeezes the sand pit type vehicle deceleration structure 3, the air intake in the speed bump type vehicle deceleration structure 4 lifts up its active part and extends out of the upper surface of the road emergency lane 1 to the maximum height, and this state is maintained until the wheel contacts and squeezes the active part of the speed bump type vehicle deceleration structure 4 extending out of the upper surface of the road emergency lane 1; when most of the vehicle weight is borne by the sand pit type vehicle deceleration structure 3, the active part of the speed bump type vehicle deceleration structure 4 extending out of the upper surface of the road emergency lane 1 is not retracted as a whole, and still has a deceleration effect; when most of the vehicle weight is borne by the speed bump type vehicle deceleration structure 4, the active part of the speed bump type vehicle deceleration structure 4 extending out of the upper surface of the road emergency lane 1 is retracted, thereby improving the surface flatness of the road emergency lane 1 and ensuring the stability of the vehicle when it is stationary.

[0074] In some embodiments, the sand pit type vehicle speed reduction structure 3 includes:

[0075] A rectangular trough 36 is longitudinally embedded and assembled on the upper surface of the emergency lane 1 of the road away from the curb 2;

[0076] An annular elastic connecting belt 32 is fixedly connected to the upper edge of the inner wall of the rectangular trough 36, and a flexible nylon cloth 31 is fixedly connected to the inner annular surface thereof;

[0077] The piston plate 33 is slidably assembled in the rectangular groove 36 in a sealed manner, and the space between the piston plate 33 and the annular elastic connecting belt 32 and the flexible nylon cloth 31 is filled with sand occupying three quarters of the volume;

[0078] The lower end of the elastic support frame 34 is fixedly mounted on the bottom surface of the inner cavity of the rectangular slot body 36 , and the upper end of the elastic support frame 34 abuts against the bottom surface of the piston plate 33 .

[0079] Specifically in this embodiment, the flexible nylon cloth 31 and the annular elastic connecting belt 32 block the sand layer above the upper end of the piston plate 33. The flexible nylon cloth 31 and the annular elastic connecting belt 32 are squeezed and deformed by the wheel, and then squeeze the sand layer to flow. The flowing sand layer squeezes the piston plate 33 to move downward and squeeze the elastic support frame 34 to contract. The air under the piston plate 33 is squeezed along the ventilation pipe 7 and enters the speed reduction belt type vehicle deceleration structure 4.

[0080] Furthermore, the surface of the flexible nylon cloth 31 is wavy when not squeezed, so that the flexible nylon cloth 31 can be deformed to a greater extent after being squeezed, so as to avoid the support of the wheel by the strength of the flexible nylon cloth 31 itself, which affects the flow degree when the wheel squeezes the sand layer. The annular elastic connecting belt 32 is used to connect the four sides of the flexible nylon cloth 31, so as to avoid the fracture of the connection of the edge of the flexible nylon cloth 31 when it is suddenly compressed.

[0081] More specifically, a sealing ring is attached to the edge of the piston plate 33 to improve the airtightness of the sliding connection between the piston plate 33 and the inner wall of the rectangular groove 36, so as to prevent the air from leaking out from the gap between the piston plate 33 and the inner wall of the rectangular groove 36 when the gas in the space below the piston plate 33 is squeezed;

[0082] It can be understood that the space between the piston plate 33 and the annular elastic connecting belt 32 and the flexible nylon cloth 31 is filled with sand occupying three quarters of the volume to avoid a lack of flow space due to excessive sand and to avoid the squeezing effect of the wheels on the sand layer due to a low sand layer.

[0083] In some embodiments, a vibration mechanism 35 is laterally fixedly mounted on the upper end of the elastic support frame 34, and includes:

[0084] A longitudinal plate 351, which is evenly and longitudinally fixedly assembled on the upper end of the elastic support frame 34;

[0085] A transverse plate 353, which is fixedly connected between adjacent longitudinal plates 351;

[0086] The vibration motor 352 is fixedly mounted on the top surface of the transverse plate 353 , and the upper end of the vibration motor 352 abuts against the bottom surface of the piston plate 33 .

[0087] Specifically in this embodiment, the sand layer filled between the piston plate 33, the annular elastic connecting belt 32, and the flexible nylon cloth 31 is vibrated and flattened by the vibration of multiple vibration motors 352, so as to be ready for next use;

[0088] Furthermore, the vibration motor 352 is connected to an external power supply to work, the vibration motor 352 is connected to the controller 9, and the controller 9 is connected to a remote control terminal to control whether the vibration motor 352 works or not through remote control;

[0089] More specifically, the vibration motor 352 is installed on a grid bracket formed by the longitudinal plate 351 and the transverse plate 353 to ensure the stability of the installation. The end of the grid bracket is fixed to the upper end of the elastic support frame 34 and can move downward as the elastic support frame 34 is compressed to keep the vibration motor 352 in contact with the bottom surface of the piston plate 33.

[0090] It is understandable that when the sand layer is vibrated and leveled by the multiple vibration motors 352, the levelness of the sand layer is ensured by controlling the vibration duration.

[0091] In some embodiments, the elastic support frame 34 includes:

[0092] The lower support column 341 is evenly fixedly mounted on the bottom surface of the rectangular tank 36;

[0093] A first guide rod 343 is fixedly mounted in the middle of the top surface of the lower support column 341, and an upper support column 342 is slidably sleeved on the upper end of the first guide rod 343;

[0094] The outer wall of the first guide rod 343 is sleeved with a first rigid spring 344, and two ends of the first rigid spring 344 are respectively against the top surface of the lower support column 341 and the bottom surface of the upper support column 342;

[0095] The upper end of the upper support column 342 abuts against the bottom surface of the piston plate 33 .

[0096] Specifically in this embodiment, the upper support column 342 is pressed downward by the piston plate 33 to compress the first rigid spring 344, and the grid bracket composed of the longitudinal plate 351 and the transverse plate 353 is fixed to the upper support column 342 and moves downward as it is pressed;

[0097] Furthermore, the first guide rod 343 plays a guiding role when the upper support column 342 moves downward, ensuring that it moves in the vertical direction.

[0098] In some embodiments, the speed reduction belt type vehicle deceleration structure 4 includes:

[0099] A rectangular frame 41 is longitudinally embedded and assembled on the upper surface of the emergency lane 1 of the road close to the curb 2;

[0100] Limiting blocks 45 are symmetrically fixedly assembled on the left and right sides of the inner cavity of the rectangular frame 41;

[0101] A rectangular plate 43 is slidably assembled in the rectangular frame 41 in a sealed manner;

[0102] The bottom surface of the rectangular plate 43 abuts against the upper ends of the limit blocks 45 on both sides;

[0103] The upper surface of the rectangular plate 43 is evenly and detachably assembled with longitudinal strip plates 44 along the width direction;

[0104] A strip window 42 is formed on the top surface of the rectangular frame 41 corresponding to the longitudinal strip plate 44 , and the upper end of the longitudinal strip plate 44 is inserted into the corresponding strip window 42 .

[0105] Specifically in this embodiment, the exhaust gas at the lower end of the sand pit type vehicle deceleration structure 3 enters between the lower part of the rectangular plate 43 and the inner cavity of the rectangular frame 41 along the vent pipe 7, and the intake air pushes the rectangular plate 43 upward and moves upward along the inner wall of the rectangular frame 41, and the upwardly moving rectangular plate 43 drives the longitudinal strip plate 44 to pass through the strip window 42 and extend out of the upper surface of the road emergency lane 1;

[0106] Furthermore, a sealing ring is attached to the outer wall of the rectangular plate 43 to ensure the airtightness between the outer wall of the rectangular plate 43 and the inner wall of the rectangular frame 41, and to prevent gas from leaking out from the gap between the outer wall of the rectangular plate 43 and the inner wall of the rectangular frame 41;

[0107] More specifically, the size of the strip window 42 is designed according to the cross-sectional size of the longitudinal strip plate 44, so as to ensure that the longitudinal strip plate 44 can be smoothly extended and retracted, and at the same time, reduce the gap between the outer wall of the longitudinal strip plate 44 and the inner wall of the strip window 42, thereby reducing the entry of external impurities;

[0108] It can be understood that the limit block 45 is set to hold the rectangular plate 43 when the rectangular plate 43 is not lifted by the expanding gas, reduce the length of the lifting path of the rectangular plate 43, and ensure that the strength of the expanding gas is sufficient to push the longitudinal strip plate 44 out of the strip window 42.

[0109] In some embodiments, the upper end of the longitudinal strip plate 44 is uniformly embedded with a pressure sensor 10 along the length direction;

[0110] The vehicle lifting and intercepting structure 5 is laterally mounted on the upper surface of the road emergency lane 1, and the vehicle lifting and intercepting structure 5 is spaced apart from the speed reduction belt type vehicle deceleration structure 4;

[0111] The pressure sensor 10 at the upper end of the speed reduction belt type vehicle deceleration structure 4 is electrically connected in parallel;

[0112] The controller 9 is electrically connected to the pressure sensor 10 connected in parallel and the rear adjacent vehicle lifting and blocking structure 5 .

[0113] Specifically in this embodiment, the pressure sensor 10 is used as a sensing component, which transmits an electrical signal to the controller 9 after receiving wheel pressure, and the controller 9 controls the lifting and blocking structure 5 of the rear adjacent vehicle to rise, so as to warn and block the wheels of the rear vehicle from moving forward;

[0114] Furthermore, there are multiple pressure sensors 10 installed on the upper end of each longitudinal strip plate 44, and the multiple pressure sensors 10 are densely distributed to ensure that when the wheel squeezes the longitudinal strip plate 44, a pressure sensor 10 will be squeezed, and when a pressure sensor 10 is squeezed, an electrical signal will be transmitted to the controller 9;

[0115] More specifically, because the multiple pressure sensors 10 are designed to be connected in parallel, when one or several pressure sensors 10 are damaged, as long as these pressure sensors 10 are not distributed adjacently, it will not cause much impact on the entire sensing control process;

[0116] It is understandable that the device needs to be inspected and maintained regularly, and whether the pressure sensor 10 is damaged is one of the items in the inspection and maintenance.

[0117] In some embodiments, the vehicle lifting and intercepting structure 5 includes:

[0118] A mounting groove 51 is transversely opened on the upper surface of the road emergency lane 1;

[0119] An electric push rod 52 is fixedly mounted on the bottom surface of the mounting groove 51, and the electric push rod 52 is electrically connected to the controller 9;

[0120] A strip-shaped stopper 53 is slidably inserted into the mounting groove 51, and the lower end of the strip-shaped stopper 53 is fixedly assembled on the upper end of the electric push rod 52;

[0121] After the pressure sensor 10 is squeezed, the controller 9 controls the electric push rod 52 to drive the upper end of the strip stopper 53 to extend out of the upper end of the installation groove 51 .

[0122] Specifically in this embodiment, the electric push rod 52 is connected to an external power supply and is controlled by the controller 9 to be powered on and off. The electric push rod 52 extends and pushes the strip block 53 to extend out of the installation groove 51. The strip block 53 extending out of the installation groove 51 plays a warning and interception role.

[0123] Furthermore, the controller 9 is connected to a remote control terminal to control whether the electric push rod 52 works or not through remote control;

[0124] More specifically, the main function of the strip block 53 extending out of the mounting groove 51 is to warn the driver that the fast lane ahead is occupied. The second function is to intercept the driver, and when the driver does not notice that the strip block 53 is raised, the collision reminds the driver to brake in time.

[0125] It is understandable that after the strip stopper 53 is hit, necessary inspection and maintenance are required to prepare for next use.

[0126] In some embodiments, a slope 54 is provided on the front side of the upper end of the strip-shaped stopper 53;

[0127] The slope 54 is evenly embedded with LED lights 55 along the length direction, and the LED lights 55 are electrically connected to the controller 9 after being connected in parallel.

[0128] Specifically in this embodiment, the LED light 55 emits light after being powered on to enhance the warning effect of the raised bar-shaped stopper 53;

[0129] Further, the controller 9 is connected to the remote control terminal, and controls the LED light 55 to light up after the bar-shaped stopper 53 is raised;

[0130] More specifically, the slope 54 is opened facing the driver's sight direction toward the road, so that the LED lights 55 installed on the slope 54 are more easily noticed by the driver;

[0131] It is understandable that the multiple LED lamps 55 are designed in parallel, and when a single or a few LED lamps 55 are damaged, the warning function of the LED lamps 55 is not affected.

[0132] In some embodiments, a side wall of the curb 2 close to the road emergency lane 1 is fixedly equipped with an anti-collision buffer device 6, which includes:

[0133] The elastic rubber plate 61 has one end of a second guide rod 63 evenly and vertically fixedly mounted on one side of the elastic rubber plate 61 close to the curb 2, and the other end of the second guide rod 63 is slidably inserted into a reserved hole on the side wall of the curb 2;

[0134] A second rigid spring 64 is sleeved on the outer wall of the second guide rod 63 , and two ends of the second rigid spring 64 are respectively pressed against the curb 2 and the side wall of the elastic rubber plate 61 .

[0135] Specifically in this embodiment, when the vehicle still retains power after passing through the vehicle emergency deceleration assembly, it hits the elastic rubber plate 61 on the curb 2, and the elastic rubber plate 61 elastically buffers the impact;

[0136] Furthermore, the impact is transmitted to the second rigid spring 64 through the elastic rubber plate 61, and the second rigid spring 64 is compressed to perform secondary elastic buffering, thereby improving the elastic buffering effect of the impact;

[0137] More specifically, the second guide rod 63 guides the compression direction of the second rigid spring 64 , thereby ensuring that the second rigid spring 64 is deflected when compressed, thereby ensuring the buffering effect of the second rigid spring 64 .

[0138] In some embodiments, a wear-resistant layer 62 is adhered and fixed to the side wall of the elastic rubber plate 61 close to the emergency lane 1 of the road.

[0139] Specifically in this embodiment, the wear-resistant layer 62 can enhance the wear-resistant property of the side of the elastic rubber plate 61 in contact with the vehicle, thereby extending the service life of the elastic rubber plate 61;

[0140] Furthermore, the wear-resistant layer 62 in this embodiment is specifically one or more of a wear-resistant coating, an alloy outer layer, and a polymer material layer;

[0141] It can be understood that the wear-resistant coating is sprayed to a required thickness, the alloy outer layer and the polymer material layer are glued together with high-strength glue, and the wear-resistant layer 62 is one of the regular repair items of the device.

[0142] In some embodiments, a flexible shielding strip 65 is pasted between the side of the elastic rubber sheet 61 close to the curb 2 and the side wall of the curb 2 .

[0143] Specifically in this embodiment, the flexible shielding belt 65 is a nylon cloth belt, which can move with the elastic rubber plate 61 and is used to shield the gap between the elastic rubber plate 61 and the curb 2 to prevent dust and impurities from entering.

[0144] In some embodiments, a connection structure 8 is installed between the lower end of the longitudinal strip plate 44 and the rectangular plate 43, which includes:

[0145] The connecting through hole 81 is opened on the rectangular plate 43 corresponding to the longitudinal strip plate 44;

[0146] The screw rod 82, the upper end of which passes through the connecting through hole 81 and is fixedly connected to the bottom surface of the longitudinal strip plate 44;

[0147] The fixing nut 83 is screwed to the lower end of the screw rod 82 , and the top surface of the fixing nut 83 abuts against the bottom surface of the rectangular plate 43 .

[0148] Specifically in this embodiment, the fixing nut 83 is used to fix the screw rod 82 and the longitudinal strip plate 44 on the rectangular plate 43. After all the fixing nuts 83 are removed, the screw rod 82 and the longitudinal strip plate 44 can be removed together, which is convenient for replacement during device inspection and maintenance;

[0149] Furthermore, the fixing nut 83 is a locking nut in this embodiment;

[0150] More specifically, there are multiple screws 82 vertically fixed at the lower end of each longitudinal strip plate 44, and the multiple screws 82 are evenly distributed along the length direction of the bottom surface of the longitudinal strip plate 44. The connecting through holes 81 are opened corresponding to the number and positions of the screws 82, and a fixing nut 83 is screwed on the lower end of each screw 82.

[0151] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
