In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0042] Since most traditional speed bumps are convex structures with fixed shapes, when the wheels of a car press on the speed bump, the speed bump will not deform. When a vehicle passes over the speed bump, an impact force will be generated, which will affect the safety and comfort of the passengers in the car. Especially when driving at night, the speed bump is located at a low position, so that the passengers cannot clearly see the speed bump, and the purpose of slowing down the driver cannot be achieved. Therefore, the present invention aims to provide a road pedestrian crossing deceleration device to solve the above technical problems.

[0043] Specific plans such as Figure 1 As shown, an embodiment of the present invention provides a pedestrian crossing deceleration device for roads, including a housing 1, a lifting assembly 3, a rotating assembly 4 and a deceleration assembly 5; the lifting assembly 3 and the rotating assembly 4 are arranged in the housing 1, and the lifting movement of the lifting assembly 3 can drive the rotating assembly 4 to achieve a 90° rotation, and the rotating assembly 4 is symmetrically arranged with respect to the lifting assembly 3; the deceleration assembly 5 is symmetrically arranged on the top of the housing 1, and is respectively connected to the rotating assembly 4, and the rotating assembly 4 drives the deceleration assembly 5 to rotate at a 90° angle.

[0044] The embodiment of the present invention provides a pedestrian crossing deceleration device for roads, which is installed on a road that needs to be decelerated. When no vehicle passes by, the lifting assembly 3 controls the rotating assembly 4 to support the deceleration assembly 5 to stand up, so that the reflector 52 on the deceleration assembly 5 can more conspicuously remind the driver to slow down. When a vehicle drives to the deceleration device, the lifting assembly 3 controls the rotating assembly 4 to support the deceleration assembly 5 to lower, so that the reflector 52 on the deceleration assembly 5 is laid flat, and the vehicle drives over the reflector 52. By adopting the pedestrian crossing deceleration device for roads of the present invention, the problem that the speed bump is not conspicuous enough in the prior art when driving, which causes the driver to be unable to decelerate in time, is effectively solved, and the speed bump can provide a conspicuous deceleration reminder to the driver.

[0045] Specifically, refer to Figure 2 The lifting assembly 3 includes a hydraulic telescopic member 31, a connecting frame 32 and a rack 33; the hydraulic telescopic member 31 is vertically arranged at the bottom of the box body 1; the connecting frame 32 is arranged at the telescopic end of the hydraulic telescopic member 31, and can move up and down with the telescopic end of the hydraulic telescopic member 31; the rack 33 is symmetrically arranged on both sides of the connecting frame 32.

[0046] In actual use, the specific working principle of the lifting assembly 3 is as follows: the telescopic rod of the hydraulic telescopic component 31 is fixedly connected to the connecting frame 32, and the two racks 33 are symmetrically installed on both sides of the connecting frame 32. The connecting frame 32 is driven up and down by the lifting movement of the hydraulic telescopic component 31, which can drive the rack 33 to move up and down, and then the rack 33 is engaged with the gear 44 on the rotating assembly 4, driving the gear 44 to rotate, and further realizing a 90° rotation through the parts on the rotating assembly 4.

[0047] In addition, the hydraulic telescopic member 31 in this embodiment can be a structural member such as a hydraulic cylinder or a pneumatic cylinder that can achieve lifting movement.

[0048] Combination Figure 3As shown, the rotating assembly 4 includes a fixed plate 41, a gear 44, a first connecting rod 45, a second connecting rod 46 and a "Z"-shaped plate 47; the fixed plate 41 is arranged on the side of the box body 1, and a movable track 42 is opened on the fixed plate 41; the gear 44 is installed on the fixed plate 41 through the first rotating shaft 43, and meshes with the rack 33; one end of the first connecting rod 45 is connected to the first rotating shaft 43, and the other end is movably connected to one end of the second connecting rod 46; the other end of the second connecting rod 46 is connected to one end of the "Z"-shaped plate 47 through the second rotating shaft 48; the "Z"-shaped plate 47 is clamped in the movable track 42 through the clamping column 49, and the clamping column 49 can drive the "Z"-shaped plate 47 to slide in the movable track 42, and the other end of the "Z"-shaped plate 47 can pass through the top of the box body 1 and be connected to the bottom of the reduction assembly 5.

[0049] In actual use, the specific working principle of the rotating assembly 4 is as follows: the rack 33 is meshed with the gear 44, and the gear 44 is driven to rotate by the up and down movement of the rack 33, and then the first connecting rod 45 coaxially connected to the gear 44 is driven to rotate synchronously with the gear; then, since the second connecting rod 46 is movably connected to the first connecting rod 45 (that is, connected by a pin shaft), the first connecting rod 45 drives the second connecting rod 46 to rotate; after that, since the second connecting rod 46 is connected to one end of the "Z"-shaped plate 47, and the center of the "Z"-shaped plate 47 is clamped in the moving track 42 through the clamping column 49, and the "Z"-shaped plate 47 can also rotate around the clamping column 49, when the gear When the wheel 44 drives the second connecting rod 46 to rotate, the "Z"-shaped plate 47 will first move upward along the movable track 42 through the clamping column 49 until the first connecting rod 45 and the second connecting rod 46 are pulled into a straight line, and then as the gear 44 continues to rotate, the end of the "Z"-shaped plate 47 connected to the second connecting rod 46 will continue to move upward, and its movement trajectory is in the shape of a 1 / 4 circle. At this time, the other end of the "Z"-shaped plate 47 passes through the top of the box body 1 (the top of the box body 1 leaves space for the other end of the "Z"-shaped plate 47 to rotate), and is connected to the bottom of the reduction assembly 5, and drives the reduction assembly 5 to achieve horizontal and vertical conversion (i.e., 90° rotation).

[0050] In addition, in order to achieve more flexible rotation of the rotating component 4 of the present embodiment, the movable track 42 is designed to connect the straight track and the 1 / 4 arc track, and the distance between the connection point between one end of the 1 / 4 arc track and the straight track and the first rotating shaft 43 is exactly the sum of the lengths of the first connecting rod 45 and the second connecting rod 46. When the second rotating shaft 48 moves to the point where the straight track is connected to the 1 / 4 arc track, as the gear 44 continues to rotate, the clamping column 49 continues to move upward along the straight track, and the second rotating shaft 48 will move along the 1 / 4 arc track, thereby achieving more stable rotation of the rotating component 4.

[0051] In addition, the rotating assembly 4 is symmetrically arranged in the box body 1. When the lifting assembly 3 is lifted or lowered, it will drive two symmetrical rotating assemblies 4 to rotate simultaneously. Two reduction assemblies 5 connected to the rotating assembly 4 are also symmetrically arranged, and the two reduction assemblies 5 can achieve a 90° rotation.

[0052] Furthermore, combined with Figure 1 As shown, the rotating assembly 4 also includes a rotating plate 410, which is arranged at the top of the box body 1 and rotatably connected to the side of the box body 1, and the other end of the "Z"-shaped plate 47 is fixedly connected to the bottom of the rotating plate 410; the deceleration assembly 5 is arranged at the top of the rotating plate 410.

[0053] In the present embodiment, specifically, a rotating plate 410 is further arranged between the other end of the "Z"-shaped plate 47 and the reduction assembly 5, and the other end of the "Z"-shaped plate 47 is fixed to the rotating plate 410, and the side of the rotating plate 410 is movably connected to one side of the side of the box body 1, which can be connected by a hinge or a hinge. As long as it is ensured that when the "Z"-shaped plate 47 rotates, the rotating plate 410 can realize a 90° rotation together with the other end of the "Z"-shaped plate 47, the reduction assembly 5 is fixed to the rotating plate 410, which can not only ensure the increase of the service life of the reduction assembly 5 during repeated use, but also ensure the stability of the reduction assembly 5 during standing up and laying down.

[0054] like Figure 1 As shown, the deceleration assembly 5 includes a deceleration base plate 51 and a reflector 52 ; the deceleration base plate 51 is fixedly connected to the top of the rotating assembly 4 ; the reflector 52 is fixedly connected to the top of the deceleration base plate 51 .

[0055] In actual application, the deceleration base plate 51 in the deceleration assembly 5 can be directly fixedly connected to the other end of the "Z"-shaped plate 47, or can be fixedly connected to the other end of the "Z"-shaped plate 47 through a rotating plate 410, and then the reflective plate 52 is set on the top of the deceleration base plate 51. When the deceleration assembly 5 is erected, the reflective plate 52 can serve as a more eye-catching reminder to the driver, thereby improving the practicality of the device.

[0056] Combination Figure 1 The top surface of the reflective plate 52 is set as an arc surface with the center downward.

[0057] In actual application, the top surface of the reflector 52 can be designed as a slope, but such a design will always have an edge, which will cause certain damage to the tire when a car passes by. Therefore, in this embodiment, the top surface of the reflector 52 is designed as an arc surface, and the center of the arc surface is downward. When a car passes by, it can be ensured that the car can pass by relatively smoothly, which can reduce damage to the vehicle tire.

[0058] In practical applications, reference Figure 1The deceleration assembly 5 also includes an elastic plate 53 , which is filled between the deceleration bottom plate 51 and the reflective plate 52 .

[0059] In this embodiment, an elastic plate 53 is filled between the deceleration base plate 51 and the reflective plate 52. When a vehicle passes over the reflective plate 52 of the deceleration assembly 5, the elastic plate 53 can play a certain buffering role, which can reduce the reverse impact force on the passengers and the driver in the vehicle. On the other hand, it can also raise the height of the deceleration assembly 5, making the deceleration reminder effect more obvious.

[0060] Combination Figure 1 The reduction gear also includes a buffer assembly 2, which is disposed in the housing 1 and can pass through the top of the housing 1 and contact the bottom of the reduction assembly 5.

[0061] In this embodiment, a buffer component 2 is also provided in the housing 1 of the reduction device, and the buffer component 2 is in contact with the bottom of the reduction component 5. When the vehicle passes over the reduction component 5, the buffer component 2 can absorb a certain impact force, reduce the reverse impact force on the passengers and the driver, and improve the comfort of the driver.

[0062] The buffer assembly 2 includes a buffer frame 21, a clamping frame 22, a tension spring 23, a buffer spring 26 and a buffer top plate 27; the specific structure is as follows Figure 1 As shown, the buffer frame 21 is arranged at the bottom of the box body 1; the two clamping frames 22 can be rotatably installed on the inner wall of the buffer frame 21 and are symmetrically arranged, and the bottoms of the two clamping frames 22 are connected by a bending rod 24, and the tops of the two clamping frames 22 can clamp the buffer top plate 27; the buffer top plate 27 is arranged at the top of the box body 1; one end of the buffer spring 26 is connected to the bottom of the buffer top plate 27, and the other end is connected to the buffer column 25, and the buffer column 25 can contact the bending rod 24; the two tension springs 23 are symmetrically arranged on both sides of the top of the buffer frame 21, and are respectively located on one side of the clamping frames 22, and the tension springs 23 are respectively connected to the upper ends of the two clamping frames 22.

[0063] Specifically, in this embodiment, the working principle of the buffer assembly 2 is as follows: when the vehicle passes over the deceleration assembly 5, the deceleration bottom plate 51 transmits the pressure to the buffer top plate 27, and the buffer top plate 27 moves downward. Since the buffer top plate 27 is connected with a buffer spring 26 below, the buffer spring 26 is deformed to absorb the impact force through the movement of the buffer top plate 27, and then the buffer spring 26 drives the buffer column 25 connected thereto to move downward, and the movement of the buffer column 25 presses the bent rod 24 into a straight rod. At this time, the clamping frame 2 connected to both ends of the bent rod 24 2 The top of the buffer frame 21 will be rotated to the middle with the fulcrum connected with the buffer frame 21 as the rotation point, and the tops of the two clamping frames 22 will clamp the buffer top plate 27. At the same time, the tension springs 23 arranged on both sides of the top of the buffer frame 21 are also stressed and in a stretched state; when the vehicle leaves, the pressure of the buffer top plate 27 disappears, the buffer spring 26 returns to its original state, and drives the buffer column 25 to move upward. At this time, the pressure of the bent rod 24 disappears and returns to its original state. The clamping frames 22 connected to both ends of the bent rod 24 are pulled by the tension of the tension spring 23 and return to their initial state.

[0064] As a further improvement of the present solution, the deceleration device further includes a vehicle sensing sensor, and the vehicle sensing sensor is connected to the hydraulic telescopic member 31 .

[0065] In this embodiment, a vehicle sensing sensor can also be set on the deceleration device. Specifically, the vehicle sensing sensor adopts the vehicle sensing sensor equipment in the prior art, or a radar detection device can be used to detect the passing vehicles, and the vehicle sensing sensor or the radar detection device transmits the signal to the control system. If a vehicle travels to a distance within 5m of the speed bump, the hydraulic telescopic part 31 is controlled by the control system to realize the lifting movement, or the vehicle sensing sensor or the radar detection device directly transmits the signal to the hydraulic telescopic part 31, driving the hydraulic telescopic part 31 to work, thereby lowering the height of the deceleration device to the height of an ordinary speed bump, and then after the vehicle presses onto the speed bump, the height of the speed bump can be further lowered by the buffer component 2 to ensure that the vehicle passes smoothly, thereby realizing the automatic sensing of the passing vehicles by the deceleration device.

[0066] In combination with the above embodiments, the working principle of the pedestrian crossing deceleration device provided by the present invention is as follows:

[0067] The box body 1 is placed in a pre-made passage. When no vehicle passes through, the hydraulic telescopic member 31 contracts to move the connecting frame 32 downward. The movement of the connecting frame 32 drives the racks 33 on both sides to move downward. The movement of the racks 33 drives the gear 44 to rotate. The rotation of the gear 44 drives the first connecting rod 45 to rotate. The rotation of the first connecting rod 45 drives the second connecting rod 46 to rotate. Since the second rotating shaft 48 moves in the moving track 42, the movement of the second rotating shaft 48 drives the "Z"-shaped plate 47 to rotate. Then, through the rotation of the "Z"-shaped plate 47, the rotating plate 410 is erected, and the deceleration assembly 5 is also erected. The reflective plate 52 can clearly remind passing drivers to slow down. When a vehicle passes by, the hydraulic telescopic rod 31 moves upward, and the movement of the connecting frame 32 drives the racks 33 on both sides to move upward, and the movement of the racks 33 drives the gear 44 to rotate, and the rotation of the gear 44 drives the first connecting rod 45 to rotate, and the rotation of the first connecting rod 45 drives the second connecting rod 46 to rotate. Since the second rotating shaft 48 moves in the moving track 42, the movement of the second rotating shaft 48 drives the "Z"-shaped plate 47 to rotate, and then the rotation of the "Z"-shaped plate 47 makes the rotating plate 410 lie flat, so that the vehicle passes the deceleration device. At the same time, when the vehicle passes over the deceleration assembly 5, it will drive the buffer top plate 27 to move downward. The movement of the buffer top plate 27 will cause the buffer spring 26 to deform and absorb the impact force. Then the buffer spring 26 drives the buffer column 25 to move downward. The movement of the buffer column 25 will deform and straighten the bent rod 24. Then the clamping frame 22 will be driven to move toward the middle. The buffer top plate 27 will be clamped by the movement of the clamping frame 22. After the vehicle leaves, the tension spring 23 will pull back the clamping frame 22, so that the buffer assembly 2 returns to normal.
