As shown in fig. 1 to 11, the present invention provides an anti-collision damage convertible road pile, which comprises a controller (not shown in the drawings) for controlling each actuating structure (such as the driving mechanism 4) to perform corresponding actions.

The overturn type road pile capable of preventing collision damage further comprises a shell 1, a connecting shaft 2, an upright post 3, a driving mechanism 4, a locking mechanism 5, a collision unlocking mechanism 6 and a license plate recognition camera (not shown in the attached drawings).

The housing 1 is buried underground, and the upper surface of the housing 1 is flush with the ground. The housing 1 is provided with a mounting cavity 11.

The connecting shaft 2 is positioned in the middle of the mounting cavity 11 and is fixedly connected with the shell 1. The lower end of the upright post 3 is rotationally connected with the connecting shaft 2, and the upper end can rotate around the hinged central line.

The driving mechanism 4 is used for driving the upright post 3 to rotate around the hinge central line thereof. Under the normal condition, the upright post 3 is overturned reciprocally by 90 degrees under the action of the driving mechanism 4. For example, the driving mechanism 4 rotates the driving column 3 forward by 90 °, so that the column 3 is erected, i.e., in a longitudinal state. When the license plate recognition camera detects that a vehicle needs to pass through, the driving mechanism 4 drives the upright post 3 to reversely rotate by 90 degrees and return to the original position, so that the upright post 3 is hidden in the installation cavity 11, namely, is in a transverse state, and the vehicle can normally pass through. So as to reciprocate.

The drive mechanism 4 is electrically connected to the controller. When the controller receives the execution signal, the controller controls the driving mechanism 4 to execute a corresponding action, namely, the upright 3 is driven to stand or hide, so that the upright 3 is in a longitudinal state or a transverse state.

The locking mechanism 5 is used to keep the drive mechanism 4 connected to the column 3. I.e. the driving mechanism 4 can effectively drive the column 3 to perform the turning action.

The impact unlocking mechanism 6 is used for disconnecting the driving mechanism 4 from the upright 3 when the upright 3 is impacted. When the upright post 3 is impacted by a vehicle, the upright post 3 can turn right due to the impact, so that the driving mechanism 4 is driven to rotate abnormally, and the driving mechanism 4 is damaged. The impact unlocking mechanism 6 is used to release the connection between the driving mechanism 4 and the pillar 3 or to make the connection between the driving mechanism 4 and the pillar 3 unstable, such as slipping, when the pillar 3 is impacted by a vehicle.

The license plate recognition camera is used for recognizing license plates to detect whether vehicles need to pass through, and is connected with the controller. When the license plate is shot by the license plate recognition camera, the fact that a vehicle needs to pass is indicated, corresponding information is transmitted to the controller, and the controller controls the driving mechanism 4 to drive the stand column 3 to turn over, so that the vehicle can pass smoothly.

In one embodiment, the driving mechanism 4 includes a first driving disk 41, a transmission 42, a driving gear 43, and a self-locking motor 44.

The first transmission disc 41 is located on one side of the lower end of the upright 3 and is fixedly connected with the upright 3, and the first transmission disc 41 is also rotatably connected with the connecting shaft 2. So that the first drive disk 41 can rotate with the upright 3.

The transmission member 42 is located at one end of the first transmission disc 41 far away from the upright column 3, and the transmission member 42 is rotatably connected with the connecting shaft 2 and can move along the axial direction of the connecting shaft 2.

One end of the transmission member 42 facing the first transmission disk 41 is provided with a second transmission disk 421, and one end of the second transmission disk 421 close to the first transmission disk 41 is uniformly provided with second transmission gear structures 4211 around the axis line thereof. One end of the first transmission disc 41 far away from the upright post 3 is uniformly provided with a first transmission tooth structure 411 around the axis line thereof. The second transmission gear structure 4211 is engaged with the first transmission gear structure 411, and when the axial movement of the first drive disk 41 and the transmission member 42 is unlocked, the first transmission gear structure 411 and the second transmission gear structure 4211 can slide relative to each other.

That is, any one of the teeth of the first transmission tooth structure 411 and the second transmission tooth structure 4211 is a wedge-shaped structure 561, and when the axial direction of the first transmission disc 41 and the second transmission disc 421 is fixed and movable because of the locking structure and is subjected to a large force, the second transmission disc 421 rotates, and the first transmission disc 41 rotates accordingly. When the axial direction of the first transmission plate 41 and the second transmission plate 421 cannot be fixed and the stress is small, the first transmission plate 41 rotates, and the second transmission plate 421 will not rotate because of the slipping of the first transmission tooth structure 411 and the second transmission tooth structure 4211.

The end of the transmission member 42 remote from the first drive disk 41 is provided with a driven gear 422. The drive gear 43 meshes with the driven gear 422. The power output shaft of the self-locking motor 44 is connected with the driving gear 43.

When the self-locking motor 44 is used, the driving gear 43 is driven to rotate, and the driving gear 43 drives the transmission piece 42 to rotate through the driven gear 422. The axial movement of the first transmission disc 41 and the second transmission disc 421 is locked by the locking mechanism 5, i.e. the drive mechanism 4 remains connected to the column 3. Therefore, the transmission member 42 can drive the first transmission disc 41 to rotate through the second transmission disc 421, and the first transmission disc 41 drives the upright post 3 to rotate, so that the upright post 3 makes a 90-degree reciprocating overturning motion.

Preferably, the self-locking motor 44 is a double output shaft motor, in which case the first transmission disk 41 is provided in two, one on each side of the upright 3. Similarly, two transmission members 42 and two driving gears 43 are provided. This configuration may make the rotation more efficient.

In one embodiment, the locking mechanism 5 includes a first slider 51, a second slider 52, a first return spring 53, a first sleeve 54, a second return spring 55, a third slider 56, a fourth slider 57, and a third return spring 58.

The first slider 51 and the second slider 52 are oppositely distributed at one end of the connecting shaft 2 close to the transmission member 42 and can be close to or far away from each other along the length direction of the shell 1. Specifically, the first slider 51 and the second slider 52 are distributed in a mirror image, and when the upright post 3 is normally turned over, the opposite surfaces of the first slider 51 and the second slider 52 are mutually abutted.

The two first return springs 53 are respectively located on the sides of the first slider 51 and the second slider 52 that are away from each other. In a natural state, the two first return springs 53 receive a pressure to provide stress in which the first slider 51 and the second slider 52 abut against each other.

The upper end of the first slider 51 is provided with a first half-sleeve structure 511, the upper end of the second slider 52 is provided with a second half-sleeve structure 521, and the first half-sleeve structure 511 and the second half-sleeve structure 521 jointly form a second sleeve 501. The first sleeve 54 is sleeved on the connecting shaft 2, and two ends of the first sleeve abut against the transmission member 42 and the second sleeve 501.

The second return spring 55 is sleeved on the connecting shaft 2 and located in the second sleeve 501. And both ends of the second return spring 55 are respectively abutted against the first sleeve 54 and the housing 1. Naturally, the second return spring 55 is under pressure to provide a stress urging the first sleeve 54 towards the driver 42.

A first inclined surface 512 is arranged on one side of the lower end of the first slider 51 facing the second slider 52, a second inclined surface 522 is arranged on one side of the lower end of the second slider 52 facing the first slider 51, and the first inclined surface 512 and the second inclined surface 522 jointly form a wedge-shaped groove 502. The third slider 56 is provided on the side of the housing 1 facing the first slider 51 and is slidable up and down in the height direction of the housing 1. The upper end of the third slider 56 is wedge-shaped 561, and fits into and abuts the wedge-shaped groove 502. Thus, when the third slider 56 is raised, the third slider 56 pushes the first slider 51 and the second slider 52 away from each other.

The lower end of the third slider 56 is abutted against the right end of the fourth slider 57, a third inclined surface 562 is arranged on one side of the lower end of the third slider 56 facing the left end of the fourth slider 57, the right end of the fourth slider 57 is stepped, the stepped parts of the right end of the fourth slider 57 are connected through a fourth inclined surface 571, and the third inclined surface 562 and the fourth inclined surface 571 are adapted to each other and abutted against each other. Thus, when the fourth slider 57 slides to the right, the third slider 56 is lifted by the third slope 562 and the fourth slope 571.

The fourth slider 57 is mounted on the side of the housing 1 facing the transmission member 42 and is slidable in the longitudinal direction of the housing 1.

The third return spring 58 is installed at the left end of the fourth slider 57, and both ends thereof are connected to the fourth slider 57 and the housing 1, respectively. Naturally, the third return spring 58 receives a tensile force to provide a stress that holds the fourth slider 57 at a position where the upper portion of the right end of the fourth slider 57 and the lower end of the third slider 56 abut against each other.

Under normal conditions, the fourth slider 57 is in the original position all the time because of receiving the effect of the elasticity of the third return spring 58, that is, the fourth slider 57 can not push the third slider 56 to rise, so that the third slider 56 can not push the first slider 51 and the second slider 52 to keep away from each other, and then the first sleeve 54 can keep conflicting with the second sleeve 501 and the transmission member 42 all the time, and thus the axial movement of the transmission member 42 and the first transmission disk 41 is locked, and then the driving mechanism 4 can normally operate.

In one embodiment, the impact unlocking mechanism 6 comprises a transmission rod 61 and an L-shaped transmission member 62, wherein the transmission rod 61 is installed at the right side of the upright post 3, and two ends of the transmission rod 61 are slidably connected with two sides of the installation cavity 11, namely, the transmission rod 61 can move along the length direction of the shell 1. Both ends of the L-shaped transmission member 62 are fixedly connected to the right end of the fourth slider 57 and one end of the transmission rod 61, respectively, and can slide along with the transmission rod 61.

When the upright post 3 is knocked and overturned to the right, the upright post 3 pushes the transmission rod 61 to move to the right, and the transmission rod 61 drives the fourth slide block 57 to move to the right by overcoming the elastic force of the third return spring 58 through the L-shaped transmission piece 62. Under the action of the third inclined surface 562 and the fourth inclined surface 571, the fourth slider 57 pushes the third slider 56 to move upward, and the third slider 56 pushes the first slider 51 and the second slider 52 to move away from each other against the elastic force of the second return spring 55 under the action of the wedge-shaped groove 502 and the wedge-shaped structure 561. The first half-sleeve structure 511 and the second half-sleeve structure 521 are separated from each other, and the end of the first sleeve 54 facing the first slider 51 becomes slidable due to the loss of support of the second sleeve 501. So that the first transmission disc 41 and the second transmission disc 421 slip, and further make the upright post 3 turn rightwards, which is an abnormal turn under the condition of vehicle collision, and cannot drive the abnormal rotation of the driving mechanism 4. Damage to the drive mechanism 4 when the upright 3 is struck by a vehicle is avoided. Meanwhile, when the upright post 3 is impacted by a vehicle, the upright post can rotate rightwards, so that the damage to the upright post 3 when the vehicle impacts the upright post 3 is reduced.

In one embodiment, the impact unlocking mechanism 6 further includes a third sleeve 63. The third sleeve 63 is rectangular, the third sleeve 63 is sleeved on the transmission rod 61 and is rotatably connected with the transmission rod 61, and one side of the third sleeve 63 is abutted against the upright column 3. When the upright post 3 is turned rightwards due to the collision, one surface of the third sleeve 63 always collides with the upright post 3, so that the contact area is increased, and the transmission effectiveness is improved.

In one embodiment, the periphery of the upright 3 is provided with a groove 31, and a warning strip 32 is arranged in the groove 31. The warning strip 32 can effectively remind that the road piles are arranged in front of the vehicle to slow down.

The invention also provides a method for the overturn type road pile for preventing collision damage, which comprises the following steps:

s1, when the upright post 3 is overturned to the right by the vehicle collision, the upright post 3 pushes the transmission rod 61 to move to the right through the third sleeve 63;

s2, the transmission rod 61 drives the fourth sliding block 57 to move rightwards by overcoming the elastic force of the third return spring 58 through the L-shaped transmission piece 62;

s3, under the action of the third inclined plane 562 and the fourth inclined plane 571, the fourth slider 57 pushes the third slider 56 to move upward;

s4, under the action of the wedge-shaped groove 502 and the wedge-shaped structure 561, the third slider 56 pushes the first slider 51 and the second slider 52 away from the first half-sleeve structure 511 and the second half-sleeve structure 521 to separate from each other against the elastic force of the second return spring 55, and the end of the first sleeve 54 facing the first slider 51 becomes slidable due to the loss of support of the second sleeve 501. So that the first transmission disc 41 and the second transmission disc 421 slip, and further make the upright post 3 turn rightwards, which is an abnormal turn under the condition of vehicle collision, and cannot drive the abnormal rotation of the driving mechanism 4. Damage to the drive mechanism 4 when the upright 3 is struck by a vehicle is avoided. Meanwhile, when the upright post 3 is impacted by a vehicle, the upright post can rotate rightwards, so that the damage to the upright post 3 when the vehicle impacts the upright post 3 is reduced.

The working principle of the invention is as follows:

when the convertible road pile of above-mentioned crashproof damage normally operates, do not receive the vehicle striking promptly, fourth slider 57 is in the normal position all the time because of receiving the effect of third reset spring 58 elasticity, and fourth slider 57 can not promote third slider 56 and rise promptly to third slider 56 can not promote first slider 51 and second slider 52 and keep away from each other, and then makes first sleeve 54 keep conflicting with second sleeve 501 and driving medium 42 all the time, thereby locks the axial displacement of driving medium 42 and first drive disk 41. An effective transmission between the first drive disk 41 and the transmission member 42 is possible. Therefore, the self-locking motor 44 can drive the upright post 3 to turn back and forth by 90 degrees.

When the upright post 3 is overturned to the right by the vehicle impact, the upright post 3 pushes the transmission rod 61 to move to the right through the third sleeve 63, and the transmission rod 61 drives the fourth slide block 57 to move to the right through the L-shaped transmission piece 62 against the elastic force of the third return spring 58. Under the action of the third inclined surface 562 and the fourth inclined surface 571, the fourth slider 57 pushes the third slider 56 to move upward, and under the action of the wedge-shaped groove 502 and the wedge-shaped structure 561, the third slider 56 pushes the first slider 51 and the second slider 52 to move away from each other against the elastic force of the second return spring 55. The first half-sleeve structure 511 and the second half-sleeve structure 521 are separated from each other, and the end of the first sleeve 54 facing the first slider 51 becomes slidable due to the loss of support of the second sleeve 501. So that the first transmission disc 41 and the second transmission disc 421 slip, and further make the upright post 3 turn rightwards, which is an abnormal turn under the condition of vehicle collision, and cannot drive the abnormal rotation of the driving mechanism 4. Damage to the drive mechanism 4 when the upright 3 is struck by a vehicle is avoided. Meanwhile, when the upright post 3 is impacted by a vehicle, the upright post can rotate rightwards, so that the damage to the upright post 3 when the vehicle impacts the upright post 3 is reduced.

When the vehicle is removed, the upright post 3 is turned leftwards under the action of manpower or the driving mechanism 4, and the fourth slide block 57 moves leftwards under the action of the third return spring 58 and moves from the original position. The third slide block 56 is lowered to the original position, and the first sleeve 54 is located on the side of the first slide block 51 and the second slide block 52 facing the transmission member 42 under the action of the second return spring 55, so that the first slide block 51 and the second slide block 52 can be restored to the original positions under the action of the first return spring 53 and abut against the first sleeve 54 to lock the axial movement thereof.
