Detailed ways

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

As shown in Figures 1-9, the present invention provides a tidal lane variable blocking ground lock, which includes a bracket 1, a blocking mechanism 2, a locking mechanism 3 and a driving assembly 4, wherein the bracket 1, the locking mechanism 3 and The driving components 4 are all installed on the road floor, and only part of the blocking mechanism 2 is exposed to the road, forming a block for oncoming vehicles. The blocking mechanism 2 is rotatably connected to the bracket 1, and the blocking direction of the blocking mechanism 2 is adjusted through rotation. Specifically, the blocking mechanism 2 is used to rotatably block the reverse direction of the lane and prompt whether there is a passage. The blocking mechanism is blocked in the reverse direction, but can be driven through in the forward direction; the locking mechanism 3 is used to control the blocking mechanism 2 to lock the rotation when driving in the reverse direction when driving along the lane, and not lock the rotation when pushing in the forward direction when driving along the lane. The driving vehicle hits the blocking mechanism 2, and the blocking mechanism 2 has a blocking effect on the vehicle because the rotation in the pushing direction is locked. On the contrary, when the vehicle travels in the forward direction, the blocking mechanism 2 acts on the blocking mechanism 2, and the blocking mechanism 2 has no blocking effect in the pushing direction. The rotational lock can directly push the blocking mechanism 2 to rotate downward, thereby allowing smooth passage; the driving assembly 4 is provided with an output end 401, and the driving assembly 4 is used to drive the output end 401 to perform linear reciprocating movement. , and drives the locking mechanism 3 to push the blocking mechanism 2 to reverse rotation, and the driving assembly 4 changes the direction of the blocking mechanism 2 according to the needs of the tidal lane, thereby achieving reversal blocking.

Among them, several blocking mechanisms 2 and several locking mechanisms 3 are arranged in rows and correspond one to one. A single locking mechanism 3 corresponds to a single blocking mechanism 2. The single corresponding setting facilitates increase and decrease and control of intervals. distance.

It can be understood that in a side-by-side arrangement, a horizontal row of blocking ground locks is arranged on the tidal lane to form a width space covering the entire tidal lane.

In a certain embodiment, in order to warn oncoming vehicles and guide the correct lane, the tidal lane variable blocking ground lock also includes an early warning mechanism 5. The early warning mechanism 5 includes a pressure sensing component 51 and a guidance component 52. The pressure sensing component 51 is disposed at the intersection of the lane to detect the driving direction of the entering vehicle. The warning and guidance component 52 is disposed at the dividing line of the lane to guide the vehicle traveling in the opposite direction into the side lane. When the vehicle is traveling in the opposite direction by When the pressure sensing component 51 detects it, the warning and guidance component 52 is activated to guide the vehicle into the side lane.

It is understandable that vehicles driving in the opposite direction may notice that they are driving in the opposite direction on the tidal lane, but it is difficult to judge whether to go left or right in a panic. At this time, the warning mechanism 5 is used to increase the prompting effect and guide the direction of the correct lane, reducing driving members’ panic.

Optionally, in order to prevent a hard collision with the blocking mechanism 2 if the vehicle speed is too fast and the blocking mechanism 2 is not responded quickly, a camera can also be installed to take pictures between the intersection and the blocking mechanism 2. It is mainly used for machine vision recognition when the vehicle enters in the opposite direction. When there is a vehicle blocking the road, while the warning and guidance component 52 is activated, the direction of the blocking mechanism 2 is changed through the driving component 4. When the vehicle leaves the lane, the signal is captured through the camera, and the driving component 4 Return the direction of the blocking mechanism 2.

In a certain embodiment, in order to have an effective prompting effect in the case of blocking, the blocking mechanism 2 includes a blocking plate body 21, a triangular block 22, a red reflective plate 23 and a green reflective plate 24. Several of the triangular blocks 22 are respectively arranged on both sides of the blocking plate body 21 facing the lane traveling direction from top to bottom, and are arranged in close proximity. The top of the blocking plate body 21 is pointed, and the red reflective plate 23 and the green reflective plate 22 are arranged in close proximity. The plates 24 are respectively arranged on the two sides of the triangular block 22. When facing the lane, the red reflective plate 23 and the green reflective plate 24 are perpendicular to the ground and parallel to the ground. On the contrary, when the orientation is changed, the positions are changed. One parallel to the ground and one perpendicular to the ground. Oppositely, the one on the other side is exactly the opposite, so that on the lane, the green reflector 24 faces the vehicle traveling in the forward direction, and the red reflector 23 faces the vehicle traveling in the opposite direction. warning effect.

It can be understood that the blocking plate body 21 can be in a rectangular, triangular or other shape, with a light top and a heavy bottom. The angle between the red reflective plate 23 and the green reflective plate 24 is not specifically controlled and only needs to be rotated to the two sides. , in the two orientation positions, the red reflective plate 23 and the green reflective plate 24 can be displayed on both sides respectively, and after changing the orientation, the display of the red reflective plate 23 and the green reflective plate 24 can be exchanged on both sides; the blocking plate body 21 The triangular block 22, the red reflective plate 23 and the green reflective plate 24 are all located on the ground.

In addition, the output end 401 includes a base plate 4011 and a frame 4012. The frame 4012 is arranged on the base plate 4011. The push plate 41 is set on the top of the frame 4012. The tops of the base plate 4011 and the frame 4012 are flat. , and during movement, neither the base plate 4011 nor the frame 4012 interferes with the bracket 1 .

Further, the bracket 1 includes a fixed frame and a rotating shaft, and the blocking plate 21 is rotationally connected to the rotating shaft, thereby forming a supporting and rotatable structure.

Optionally, the driving assembly 4 includes a driving motor, a transmission gear set and a rack. The output shaft of the driving motor is connected to the driving end of the transmission gear set, and the transmission gear set meshes with the rack. The rack is connected to the output end 401 , and the rack is fixed on the base plate 4011 .

Among them, the transmission gear set consists of a worm connected to the output end of the drive motor, a worm gear arranged aside, a first gear and a second gear. The worm gear meshes with the worm for transmission. The worm gear rotates coaxially with the first gear. The first gear and the second gear The gear meshes and transmits, and the second gear meshes and transmits with the rack, thereby transmitting the transmission to the rack to control the movement of the output end 401.

In one embodiment, in order to simplify the structure and effectively rotate the blocking mechanism 2 and lock one side while the other side is rotatable, the locking mechanism 3 includes a pair of oppositely disposed on the output end 401 The push plate 31 and a pair of bumps 32 are respectively provided on the front and back of the blocking plate body 21. The pushing plates 31 are staggered front and back to respectively correspond to the positions of the bumps 32. The blocking plate body 21 is located on two Between the opposite sides of the push plate 31, when the root of the push plate 31 is in close contact with the bump 32 on the corresponding side, the green reflective plate 24 on one side of the blocking plate body 21 It is facing away from the red reflective plate 23 on the other side. The driving assembly 4 drives the output end 401 to move along the lane direction, driving the push plate 31. When the push plate 31 moves, it will push to the corresponding bump 32. Due to the pushing effect, the blocking mechanism 2 can rotate. Then a force is exerted on the push plate 31 to rotate. When the bump 32 rotates, the bump 32 moves downward along the push surface of the push plate 31 and reaches the root, whereupon the driving of the drive assembly 4 is stopped. At the root position, due to the angle formed, the pushing surface of the pushing plate 31 does not move, forming a block for the bump 32 on that side. Therefore, when the pushing surface acts on the tip of the blocking mechanism 2 and rotates toward the pushing plate 31, On the other hand, there is no obstruction on the other side of the position of the bump 32, so the rotation acting on the blocking mechanism 2 and away from the push plate 31 can be carried out, and the blocking mechanism 2 can be pressed down and rotated, so that it can be rotated smoothly. pass.

It can be understood that when the root of the push plate 31 is in close contact with the protrusion 32 on the corresponding side, and the tip of the blocking mechanism 2 faces the direction of the push plate 31, the tip faces in the blocking direction. The bump 32 on the other side is located above the side and has a certain distance from the push plate 31 on the other side. The side corresponding to the blocking mechanism 2 is the passage direction.

Optionally, the shape of a pair of push plates 31 is a right-angled triangle, and the hypotenuses of the two push plates 31 are opposite, the shape of the protrusions 32 is circular, and the blocking plate body 21 The bottom surface is arc-shaped.

In one embodiment, in order to detect the driving direction of the vehicle, the pressure sensing assembly 51 includes a base 511, a pressure sensor 512 and a pressure plate 513. The two pressure sensors 512 are arranged one after another along the lane direction. On the base 511, two pressure plates 513 are respectively arranged on the top of the two pressure sensors 512. When a driving vehicle passes the pressure sensing assembly 51, it will first touch one pressure plate 513 and the corresponding pressure sensor 512, and then touch it. By pressing another pressure plate 513 and the corresponding pressure sensor 512, and using the sequence difference to measure and control the vehicle's driving direction, the warning and guidance component 52 can be activated more accurately, and can adapt to changes in the tidal lane and driving direction.

It can be understood that when traveling in the forward direction, the pressure sensor 512 one and the pressure sensor 512 two are pressed successively, and when traveling in the reverse direction, the pressure sensor 512 two and the pressure sensor 512 one are pressed successively.

In a certain embodiment, the warning and guidance assembly 52 includes a bottom plate 521, a solar panel 522, a solar battery 523, a ladder block 524 and a guide light 525. The bottom plate 521 is embedded on the road, and the solar panel 522 is embedded in the bottom plate 521, and a transparent plate is provided on the top of the solar panel 522 to protect the solar panel 522. The solar battery 523 is arranged inside the ladder block 524. The battery panel 522 and the solar battery 523 are connected through a photovoltaic charge controller to provide solar power. The guide lights 525 are respectively arranged on both sides of the ladder block 524. The guide lights 525 are used to illuminate when a retrograde vehicle enters by mistake. Light guide.

It can be understood that the function of the step block 524 is to form a visual separation between the guide lights 525 on both sides. For vehicles traveling in two directions, only the guide lights 525 on the corresponding side can be observed to prevent errors in guidance.

Among them, the height of the ladder block 524 ranges from three to five centimeters, which does not affect the driving of the vehicle and also has the function of buffering the speed of the vehicle.

In addition, the ladder blocks 524 are arranged at equidistant intervals on the bottom plate 521, and the solar panels 522 are arranged within the intervals. Through the protrusions of the ladder blocks 524, the solar panels 522 can be protected, and the solar panels 522 can be protected when cars pass by. Pressure on solar panel 522.

The specific working process of the variable direction blocking floor lock in the present invention: the side facing the blocking plate body 21 is the blocking side. At this time, the corresponding bump 32 fits with the root of the push plate 31 on that side to form a lock. ; When the blocking direction needs to be changed, the output end 401 moves under the drive of the driving assembly 4, driving the push plate 31 on the other side to move toward this side, and pushing the bump 32 on the other side downward along the slope of the push plate 31 Slide, slide to the root, thereby rotating the blocking plate body 21 to the other side, and forming a lock on that side; when the vehicle is traveling on the unlocked side, due to the inclined direction of the blocking plate body 21, the traveling side To follow the inclined plane, the vehicle acts on this surface of the blocking plate body 21, forming a downward thrust. Since there is no obstruction on the side of the bump 32 away from the push plate 31, the blocking plate body 21 can be pushed down in this rotation direction. rotation, the vehicle will pass by normally, and the bottom end of the blocking plate body 21 is heavier than the tip of the blocking plate body 21. After the vehicle passes by, under the action of gravity, the blocking plate body 21 can automatically rotate back to the bump 32 to fit the push plate 31 The location of the roots.
