[0031] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Example:

[0033] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of the one-way traffic restriction device 10 provided in an embodiment of the present invention applied to a parking lot management system 100. The upward arrow in the figure indicates the direction of one-way traffic of vehicles.

[0034] The embodiment of the present invention provides a one-way traffic restriction device 10, which has the characteristic of being able to restrict the one-way passage of vehicles. The one-way traffic restriction device 10 can be applied to one-way traffic restriction scenes such as parking lot management systems 100 and checkpoints. Of course, the one-way traffic restriction device 10 can also be used independently.

[0035] Among them, taking the one-way traffic restriction device 10 applied to the parking lot management system 100 as an example, the parking lot management system 100 includes the above-mentioned one-way traffic restriction device 10, which is set on the ground of the passage to restrict the vehicle from going in the opposite direction. Of course, the parking lot management system 100 can also include a gate 20 and / or a vehicle identification device 30, etc. The gate 20 is used to be installed in the passage. When a vehicle enters the parking lot through the passage, the gate 20 releases the vehicle, and the vehicle passes over the one-way traffic restriction device 10. After passing through the one-way traffic restriction device 10, the one-way traffic restriction device 10 will restrict the vehicle from passing in the opposite direction over the one-way traffic restriction device 10, thereby restricting the vehicle from going in the opposite direction, and standardizing the parking process.

[0036] Since the parking lot management system 100 adopts the one-way traffic restriction device 10 provided by the embodiment of the present invention, the parking lot management system 100 also has the characteristic of being able to restrict the one-way passage of vehicles.

[0037] The following will specifically introduce the structure, working principle and beneficial effects of the one-way traffic restriction device 10 provided in an embodiment of the present invention.

[0038] See also Figure 2 and Figure 3 , Figure 2 This is a schematic structural diagram of a one-way traffic restriction device 10 from a first viewing angle provided in an embodiment of the present invention. Figure 3 This is a schematic structural diagram of a second viewing angle of the one-way traffic restriction device 10 provided in an embodiment of the present invention.

[0039] The one-way traffic restriction device 10 includes a top plate 12, a bottom plate 15, a reset elastic member 17 and a connecting rod mechanism 19. The reset elastic member 17 and the connecting rod mechanism 19 are arranged between the bottom plate 15 and the top plate 12 to prop up the top plate 12 so that when a vehicle passes by and is pressed against the top plate 12, the top plate 12 can be rotated to the vicinity of the bottom plate 15 to facilitate the passage of the vehicle. After the vehicle passes, the reset elastic member 17 and the connecting rod mechanism 19 will prop up the top plate 12 to restrict the vehicle from passing in the opposite direction.

[0040] Among them, the two opposite sides of the top plate 12 are respectively a pass side 121 and a prohibited side 122, and the bottom plate 15 is used to be installed on the ground and is rotatably connected to the pass side 121 of the top plate 12, so that the top plate 12 can rotate relative to the bottom plate 15, so that the pass side 121 and the prohibited side 122 of the top plate 12 are approximately equal in distance from the ground to facilitate the passage of vehicles, and the prohibited side 122 can also be made higher than the pass side 121 to limit the movement of vehicles from the prohibited side 122 to the pass side 121. The reset elastic member 17 is connected to the bottom plate 15, and the connecting rod mechanism 19 is rotatably connected to the top plate 12 and is rotatably connected to the reset elastic member 17. When no vehicle is pressed on the top plate 12, the top plate 12 can be supported by the connecting rod mechanism 19 under the action of the elastic force of the reset elastic member 17, so that the height of the prohibited side 122 is higher than the height of the passing side 121, that is, the distance between the prohibited side 122 and the ground is greater than the distance between the passing side 121 and the ground, and when the vehicle is pressed on the top plate 12, the top plate 12 can be turned to the bottom plate 15 under the pressure of external force. Since the reset elastic member 17 is provided, in the process of the top plate 12 turning to the bottom plate 15, the connecting rod mechanism 19 compresses or stretches the reset elastic member 17 to cause the reset elastic member 17 to undergo elastic deformation, so that after the vehicle passes the top plate 12, the reset elastic member 17 supports the top plate 12 through the connecting rod mechanism 19, so that the height of the prohibited side 122 is restored to be greater than the height of the passing side 121.

[0041] In this way, by providing a rotatably connected bottom plate 15 and top plate 12, and the passing side 121 is rotatably connected to the bottom plate 15, so that the vehicle can pass through the one-way restriction device 10 from the passing side 121 to the prohibited side 122, and providing a reset elastic member 17 and a connecting rod mechanism 19, so that after the vehicle passes, the top plate 12 rotates to a position where the prohibited side 122 is higher than the passing side 121, so as to restrict the vehicle from passing through the one-way restriction device 10 from the prohibited side 122 to the passing side 121, so as to play the role of one-way restriction. In addition, by providing a connecting rod mechanism 19 rotatably connected to the top plate 12 and the reset elastic member 17, the top plate 12 and the reset elastic member 17 are indirectly rotatably connected, thereby reducing the influence of the rotating top plate 12 on the deformation and recovery of the reset elastic member 17, and improving the stability of the one-way restriction device 10.

[0042] It should be noted that, in the present embodiment, the reset elastic member 17 is arranged along the surface of the bottom plate 15 facing the top plate 12. In other words, the reset elastic member 17 is extended and retracted along the surface of the bottom plate 15. In the process of the top plate 12 turning toward the bottom plate 15, the connecting rod mechanism 19 is driven by the top plate 12 and drives the reset elastic member 17 to undergo elastic deformation along its surface on the bottom plate 15, thereby further improving the stability of its elastic deformation.

[0043] Furthermore, a sharp portion (not marked in the figure) can be provided on the edge of the prohibited side 122 of the top plate 12, so that the prohibited side 122 is higher than the passable side 121, so as to restrict the reverse movement of the vehicle and prevent the vehicle from forcibly reversing from the prohibited side 122 to the passable side 121, thereby improving the restriction capability of the one-way restriction device 10 and also playing an anti-theft role to a certain extent.

[0044] It should be noted that, in the present embodiment, the sharp portion is a sawtooth shape formed by cutting the edge of the no-entry side 122 . In other embodiments, the sharp portion may also be a sharp-shaped component separately connected to the no-entry side 122 .

[0045] Furthermore, the top plate 12 may include a main body 126 and a first side edge 124 and a second side edge 125 located at a passable side 121 and a prohibited side 122, respectively. The first side edge 124 is arranged at an angle with the main body 126, and the second side edge 125 is also arranged at an angle with the main body 126. The first side edge 124 and the second side edge 125 are also arranged toward the bottom plate 15. In other words, the passable side 121 and the prohibited side 122 of the top plate 12 are curved toward the ground to facilitate vehicles to pass through the top plate 12, thereby improving the user experience.

[0046] See also Figure 3 and Figure 4 , Figure 4 This is a schematic structural diagram of a one-way traffic restriction device 10 provided in an embodiment of the present invention when the top plate 12 is see-through.

[0047] The connecting rod mechanism 19 may include a first connecting rod 191, wherein one end of the first connecting rod 191 is rotatably connected to the top plate 12, and the other end is connected to the reset elastic member 17, and the other end of the reset elastic member 17 is connected to the bottom plate 15, and, in the process of the top plate 12 turning to the bottom plate 15, the end of the first connecting rod 191 away from the top plate 12 can compress or stretch the reset elastic member 17. In other words, in the process of the top plate 12 turning to the bottom plate 15, the first connecting rod 191 is driven by the top plate 12, and the first connecting rod 191 rotates relative to the top plate 12 and the reset elastic member 17 to convert the rotation action of the top plate 12 into an action of driving the reset elastic member 17 to compress or stretch, so that the reset elastic member 17 undergoes elastic deformation. By setting the first connecting rod 191, the stability of the elastic deformation of the reset elastic member 17 is improved.

[0048] It should be noted that, in this embodiment, when the top plate 12 turns to the bottom plate 15, the first connecting rod 191 pushes the reset elastic member 17 to compress the reset elastic member 17, so that the connection between the first connecting rod 191 and the reset elastic member 17 is not easy to loosen, and the connection between the two is more stable.

[0049] Furthermore, a connecting groove 151 may be provided on the bottom plate 15, and a reset elastic member 17 is arranged in the connecting groove 151, and one end of the reset elastic member 17 away from the first connecting rod 191 is connected to the inner wall of the connecting groove 151, so that in the process of the top plate 12 turning to the bottom plate 15, the end of the first connecting rod 191 away from the top plate 12 slides in the connecting groove 151, thereby driving the reset elastic member 17 to undergo elastic deformation. The connecting groove 151 can limit the elastic deformation of the reset elastic member 17 in the groove, further improving the deformation stability of the reset elastic member 17, and by accommodating the reset elastic member 17 in the connecting groove 151, the reset elastic member 17 does not occupy the space between the top plate 12 and the bottom plate 15, so that when the top plate 12 turns to the bottom plate 15 to the extreme position, the thickness of the one-way restriction device 10 is reduced, further facilitating the vehicle to pass through the top plate 12.

[0050] It should be noted that, in the present embodiment, the direction from the passing side 121 to the prohibited side 122 is the extension direction of the connecting groove 151. In other words, in the process of the top plate 12 turning to the connecting groove 151, the end of the first connecting rod 191 away from the top plate 12 drives the reset elastic member 17 to undergo elastic deformation in the connecting groove 151 toward the passing side 121 or the prohibited side 122. Of course, in other embodiments, the extension direction of the connecting groove 151 may also be a direction perpendicular to the direction from the passing side 121 to the prohibited side 122.

[0051] Furthermore, the connecting rod mechanism 19 also includes a second connecting rod 192 and a third connecting rod 193, one end of the second connecting rod 192 is connected to the end of the first connecting rod 191 away from the reset elastic member 17, and the other end is rotatably connected to the top plate 12 to rotationally connect the top plate 12 and the end of the first connecting rod 191 away from the reset elastic member 17, that is, the first connecting rod 191 is rotatably connected to the top plate 12 through the second connecting rod 192. One end of the third connecting rod 193 is rotatably connected to the inner wall of the connecting groove 151, and the other end is rotatably connected to the end of the second connecting rod 192 away from the top plate 12. In this way, the second connecting rod 192 is rotatably connected to the end of the first connecting rod 191 away from the reset elastic member 17 by the top plate 12, and the third connecting rod 193 is rotatably connected to the end of the first connecting rod 191 away from the reset elastic member 17 by the bottom plate 15. The end of the first connecting rod 191 connected to the reset elastic member 17 can slide in the connecting groove 151 to form a crank slider mechanism, thereby further improving the stability of the compression reset elastic member 17.

[0052] Furthermore, in this embodiment, the number of the first connecting rod 191, the second connecting rod 192 and the third connecting rod 193 is two, and the two third connecting rods 193 are respectively connected to the two opposite side walls of the connecting groove 151, the two first connecting rods 191 are respectively rotatably connected to the two third connecting rods 193, and the two second connecting rods 192 are respectively rotatably connected to the two third connecting rods 193, so as to improve the stability of the connecting rod mechanism 19 in supporting the top plate 12.

[0053] It should be noted that, in the present embodiment, there are two sets of connecting rod mechanisms 19 and two reset elastic members 17, which are distributed one by one between the top plate 12 and the bottom plate 15 to evenly support the top plate 12. In addition, when the top plate 12 turns toward the bottom plate 15 to the extreme position, the first connecting rod 191, the second connecting rod 192 and the third connecting rod 193 are all located in the connecting groove 151. In this way, the thickness of the one-way traffic restriction device 10 at the extreme position is further reduced.

[0054] Please continue reading Figure 4 Furthermore, a connection reinforcement portion 127 is provided on the top plate 12 , and the connection reinforcement portion 127 extends from the prohibited side 122 to the passable side 121 , so as to strengthen the structural strength of the top plate 12 .

[0055] In addition, the connection reinforcement portion 127 is rotatably connected to the connection groove 151 to rotationally connect the top plate 12 and the bottom plate 15, and the connection reinforcement portion 127 is also rotatably connected to the first connecting rod 191 to rotationally connect the top plate 12 and the first connecting rod 191, and the connection groove 151 is opposite to the connection reinforcement portion 127. When the top plate 12 turns toward the bottom plate 15 to the extreme position, the connection reinforcement portion 127 can also be located in the connection groove 151, further reducing the thickness of the one-way traffic restriction device 10 at the extreme position.

[0056] Furthermore, a hinge seat (not shown) is provided on the connection reinforcement portion 127 . The hinge seat is located in the connection groove 151 and is rotatably connected to the side wall of the connection groove 151 .

[0057] See also Figure 5 , Figure 5 for Figure 4 Schematic diagram of the locally enlarged structure at V in the middle.

[0058] The reset elastic member 17 may also include an elastic portion 171 and a sliding portion 172, the sliding portion 172 is slidably connected to the connecting groove 151, one end of the elastic portion 171 is connected to the inner wall of the connecting groove 151, and the other end is connected to the sliding portion 172, the sliding portion 172 is rotatably connected to the end of the first connecting rod 191 away from the top plate 12, in this way, by providing the sliding portion 172 slidably connected to the connecting groove 151, the end of the first connecting rod 191 away from the top plate 12 can slide in the connecting groove 151 more stably and smoothly.

[0059] Furthermore, the resetting elastic member 17 may further include a shock absorbing portion 173, one end of which is connected to the inner wall of the connecting groove 151, and the other end of which is connected to the sliding portion 172. In this way, the shock absorbing portion 173 is provided to suppress the vibration of the elastic portion 171, and the elastic member slowly lifts the top plate 12, thereby reducing the probability of the prohibited side 122 damaging the vehicle.

[0060] The working principle of the one-way traffic restriction device 10 provided in the embodiment of the present invention is:

[0061] The two opposite sides of the top plate 12 are respectively a passing side 121 and a prohibited side 122, and the bottom plate 15 is used to be installed on the ground and is rotatably connected to the passing side 121 of the top plate 12, so that the top plate 12 can rotate relative to the bottom plate 15, so that the passing side 121 and the prohibited side 122 of the top plate 12 are approximately equal in distance from the ground to facilitate the passage of vehicles, and the prohibited side 122 can also be made higher than the passing side 121 to limit the movement of vehicles from the prohibited side 122 to the passing side 121. The reset elastic member 17 is connected to the bottom plate 15, and the connecting rod mechanism 19 is rotatably connected to the top plate 12 and is rotatably connected to the reset elastic member 17. When no vehicle is pressed on the top plate 12, the top plate 12 can be supported by the connecting rod mechanism 19 under the action of the elastic force of the reset elastic member 17, so that the height of the prohibited side 122 is higher than the height of the passing side 121, that is, the distance between the prohibited side 122 and the ground is greater than the distance between the passing side 121 and the ground, and when the vehicle is pressed on the top plate 12, the top plate 12 can be turned to the bottom plate 15 under the pressure of external force. Since the reset elastic member 17 is provided, in the process of the top plate 12 turning to the bottom plate 15, the connecting rod mechanism 19 compresses or stretches the reset elastic member 17 to cause the reset elastic member 17 to undergo elastic deformation, so that after the vehicle passes the top plate 12, the reset elastic member 17 supports the top plate 12 through the connecting rod mechanism 19, so that the height of the prohibited side 122 is restored to be greater than the height of the passing side 121. In this way, by providing a rotatably connected bottom plate 15 and top plate 12, and the passing side 121 is rotatably connected to the bottom plate 15, so that the vehicle can pass through the one-way restriction device 10 from the passing side 121 to the prohibited side 122, and providing a reset elastic member 17 and a connecting rod mechanism 19, so that after the vehicle passes, the top plate 12 rotates to a position where the prohibited side 122 is higher than the passing side 121, so as to restrict the vehicle from passing through the one-way restriction device 10 from the prohibited side 122 to the passing side 121, so as to play the role of one-way restriction. In addition, by providing a connecting rod mechanism 19 rotatably connected to the top plate 12 and the reset elastic member 17, the top plate 12 and the reset elastic member 17 are indirectly rotatably connected, thereby reducing the influence of the rotating top plate 12 on the deformation and recovery of the reset elastic member 17, and improving the stability of the one-way restriction device 10.
