[0002] A highway ramp is a road on the right side of the highway exit or entrance, usually 150-200 meters long. A ramp, also known as an approach road, is an engineering term that usually refers to a short section of a road that provides vehicles with access to and from the main line, highway, elevated road, bridge, driving tunnel, etc., and adjacent auxiliary roads, or other main line land bridges, ramps, approach roads, and distribution roads. It is the main traffic construction that constitutes a road interchange.

[0003] In the existing highway ramps, there is a lack of structures for observing the traffic flow and blocking the ramp exits. As a result, when the traffic flow is large, the vehicles in the ramp cannot timely understand the traffic conditions on the main road, resulting in congestion, which is not conducive to the normal driving of vehicles. Based on the existing technical deficiencies, the utility model designs a device for highway ramp merging assistance. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 A device for assisting highway ramp merging includes a fixed base 1, a display structure 3, a driving structure 4, a second display screen 7, and a high-speed camera 9. A vertical pole 2 is arranged on the top of the fixed base 1. The display structure 3 includes a rotating drum 31. The rotating drum 31 is sleeve-connected with the vertical pole 2. A toothed ring 32 is installed on the outer surface of the rotating drum 31. A blocking frame 33 is installed on one side of the outer surface of the rotating drum 31. A first display screen 34 is arranged inside the blocking frame 33. A sun visor 35 is arranged on one side of the outer surface of the blocking frame 33. The sun visor 35 is arranged above the first display screen 34.

[0021] See also Figure 4 The driving structure 4 includes a housing 41, a fixing groove 42 is provided inside the housing 41, and the fixing groove 42 is installed in the vertical rod 2 by bolts. A first fixing rod 43 is installed inside the housing 41, and a first fixing ring 44 is installed at one end of the first fixing rod 43, and a servo motor 45 is installed inside the first fixing ring 44. A rotating rod 48 is installed at one end of the output shaft of the servo motor 45, and a gear 49 is installed at one end of the bottom of the rotating rod 48, and the outer surface of the gear 49 is meshed with the outer surface of the toothed ring 32. Two second fixing rods 46 are installed inside the housing 41, and a support ring 47 is installed at one end of the two second fixing rods 46, and the two support rings 47 are sleeved on the outer surface of the rotating rod 48.

[0022] The servo motor 45 drives the output shaft thereof to drive the rotating rod 48 to rotate. Since the outer surface of the gear 49 meshes with the outer surface of the toothed ring 32, when the rotating rod 48 rotates, the rotating drum 31 drives the blocking frame 33 to rotate, thereby blocking the ramp exit.

[0023] See also Figure 1-2 A second fixing ring 5 is installed on the outer surface of the pole 2, and a side frame 6 is installed on one side of the outer surface of the second fixing ring 5. The side frame 6 is connected to the second display screen 7 by bolts. A controller 8 is arranged at one end of the top of the pole 2, and the controller 8 is rotatably connected to the high-speed camera 9.

[0024] The traffic flow on the main road of the highway is photographed by the high-speed camera 9, and the captured traffic flow image of the main road is projected onto the first display screen 34 through the controller 8 for viewing by the vehicle drivers on the ramp. At the same time, the road conditions of the main road can be projected and broadcasted through the second display screen 7 to remind the driver that there is heavy traffic on the road ahead and to drive carefully.

[0025] Working principle, when a device for assisting the merging of highway ramps is used, in the initial state, the fixed base 1 is first installed at the highway ramp exit by bolts, and the traffic flow on the highway main road is photographed by the high-speed camera 9. The captured image of the traffic flow on the main road is projected onto the first display screen 34 through the controller 8 for the vehicle drivers in the ramp to watch. At the same time, the road conditions of the main road can be projected and broadcasted through the second display screen 7 to remind the driver that the traffic flow on the road ahead is heavy and to drive carefully. If congestion begins to occur on the main road, the servo motor 45 can be driven by its output shaft to drive the rotating rod 48 to rotate. Since the outer surface of the gear 49 is meshed with the outer surface of the tooth ring 32, when the rotating rod 48 rotates, the rotating drum 31 can drive the blocking frame 33 to rotate, thereby blocking the ramp exit. When the traffic flow on the main road is small, the blocking frame 33 is reset to allow the vehicles in the ramp to pass.
