Description

A traffic intersection vehicle and pedestrian guidance device Technical Field

[0001] This invention belongs to the field of traffic safety guidance technology, specifically relating to a vehicle and pedestrian guidance device at a traffic intersection. Background Technology

[0002] The intersection of two or more roads is a crucial point for the convergence, turning, and evacuation of vehicles and pedestrians, serving as a vital artery for traffic. The rational design of road intersections and the organization and management of traffic flow are essential for improving traffic capacity and ensuring traffic safety. Especially at intersections where non-motorized vehicles and pedestrians share the road, conflict points increase, and each conflict point carries the potential risk of a traffic accident. The safety and efficiency of at-grade intersections largely depend on the proper placement of traffic lights, traffic signs, road markings, and various guidance devices.

[0003] Existing traffic lights are typically fixed to one side of an intersection, requiring vehicles and pedestrians to observe the corresponding traffic light before proceeding. However, in practice, fixed traffic lights have blind spots. For example, when large vehicles are queuing, non-motorized vehicles or cars behind them often cannot see the traffic light changes in time, leading to delayed starts or running red lights, affecting traffic efficiency and safety. Furthermore, in emergency situations, such as at intersections near hospitals or fire stations, if pedestrians or emergency personnel need to cross quickly, the lack of timely and effective warnings to vehicles can easily cause traffic accidents and secondary injuries.

[0004] While some guidance devices with camera monitoring and warning functions exist in the existing technology, their displays are mostly fixed installations with a single angle, making it difficult to meet the observation needs of vehicles and pedestrians coming from different directions. Especially when large vehicles obstruct the view, the reliability of signal transmission needs improvement. Therefore, it is necessary to provide a traffic intersection guidance device that can display signals from multiple angles, facilitate observation by vehicles and pedestrians behind, and has emergency warning functions, to compensate for the shortcomings of existing traffic lights in terms of field of view coverage and emergency response. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle and pedestrian guidance device at a traffic intersection to solve the problems mentioned in the background art.

[0006] This invention provides the following technical solution: a vehicle and pedestrian guidance device for traffic intersections, comprising a movable base and a protective box; the protective box is installed on the top of a column on the movable base;

[0007] The protective box is equipped with an information display component, which includes a display screen, warning light strips, and warning signs.

[0008] The top of the protective box is hinged with a first rocker arm and a second rocker arm. The first rocker arm is connected to the drive motor in the protective box. The first rocker arm and the second rocker arm cross each other. A connecting rod is hinged between the top ends of the first rocker arm and the second rocker arm. A support plate is installed on the connecting rod. The display is installed on a rotating seat on the support plate. A counterweight is installed at the lower end of the display. Warning light strips are distributed around the outer ring of the display. Hanging lugs are provided on the left and right sides of the connecting rod on the support plate. Warning light signs are hinged to the hanging lugs.

[0009] Furthermore, a first camera and a second camera are installed on the pillar, one in front of the other and one behind the other, below the protective box.

[0010] Furthermore, a fixed roller and a movable roller are installed inside the protective box. The fixed roller is connected to the protective box via a fixed bracket, and the movable roller is connected to the protective box via an "L"-shaped rod. The movable roller is connected to the corner of the "L"-shaped rod. The first end of the "L"-shaped rod is hinged to the protective box, and the second end of the "L"-shaped rod is connected to a spring-loaded push-pull assembly. The spring-loaded push-pull assembly causes the "L"-shaped rod to swing, causing the movable roller to approach the fixed roller.

[0011] A lifting rod is held between a fixed roller and a movable roller. The slider at the bottom of the lifting rod slides in conjunction with the guide rail in the protective box. A trigger block is installed on the top of the lifting rod. Two proximity switches are installed one above the other inside the protective box, corresponding to the first camera and the second camera, respectively.

[0012] Furthermore, a driven gear is installed on the shaft of the fixed roller; a transmission shaft is installed inside the protective box, on which a driving gear and a driven pulley are installed. The driving gear meshes with the driven gear, and the driven pulley is connected to the driving pulley on the drive motor via a belt.

[0013] Furthermore, the elastic push-pull assembly includes a pull rod, a tension spring, and a recycling box. The tail of the pull rod is slidably inserted into the recycling box, the tension spring is connected between the pull rod and the recycling box, and the pull ring at the head of the pull rod is movably sleeved on the second rod of the "L"-shaped rod.

[0014] Furthermore, the outer layer of both the fixed roller and the movable roller is a rubber layer.

[0015] Furthermore, the mobile base includes a support platform and omnidirectional wheels located at the bottom of the support platform and equipped with brakes.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] The present invention provides a vehicle and pedestrian guidance device for traffic intersections, which has the following beneficial technical effects:

[0018] Through the linkage design of the first rocker arm, the second rocker arm, and the connecting rod, the display can tilt back and forth under the control of the drive motor. Combined with the self-adjusting function of the counterweight, the display always remains upright, ensuring that vehicles and pedestrians from different directions can clearly observe the displayed content, thus overcoming the visual blind spot problem caused by the limited viewing angle of fixed traffic lights.

[0019] The protective enclosure is equipped with a transmission system consisting of a lifting rod, fixed rollers, and movable rollers. Together with a trigger block and proximity switch, it can automatically switch between the images captured by the first and second cameras based on the tilt of the display. When the display tilts in a certain direction, it simultaneously displays real-time road conditions in that direction, achieving a "tilt-to-switch" response and improving the accuracy and real-time nature of information transmission.

[0020] The display features a warning light strip around its outer edge, and a warning light sign is hinged below the support panel, forming a multi-layered visual warning system. In emergency situations (such as emergency access routes or accident scenes), flashing lights or text prompts can enhance the warning effect, reminding vehicles and pedestrians to take evasive action and reducing the risk of traffic accidents.

[0021] The lifting rod is held between the fixed roller and the movable roller. Combined with the "L"-shaped rod and the elastic push-pull assembly, the lifting rod can move smoothly up and down. The drive motor is driven by pulleys and gears to ensure that the lifting and tilting are synchronized. The overall structure is compact, the operation is stable, and it can be used for a long time under various environmental conditions. Attached Figure Description

Detailed Implementation

[0031] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] As shown in Figures 1-4: A vehicle and pedestrian guidance device for traffic intersections includes a movable base 1 and a protective box 3; the movable base 1 includes a support platform 1.2 and casters 1.3 with brakes located at the bottom of the support platform 1.2, facilitating overall movement and fixation. The protective box 3 is installed on the top of the column 1.1 on the movable base 1;

[0033] The protective box 3 is equipped with an information display component, which includes a display 4, a warning light strip 5, and a warning sign 6. To achieve multi-angle display, the top of the protective box 3 is hinged with a first rocker arm 7 and a second rocker arm 8. The first rocker arm 7 is connected to the drive motor 2 in the protective box 3 and serves as the active arm. The first rocker arm 7 and the second rocker arm 8 cross each other, and a connecting rod 9 is hinged between the top ends of the first rocker arm 7 and the second rocker arm 8. A support plate 10 is installed on the connecting rod 9. The display 4 is installed on a rotating seat 11 on the support plate 10. A counterweight 12 is installed at the lower end of the display 4. The warning light strip 5 is distributed around the outer ring of the display 4. The support plate 10 has hanging lugs 13 on the left and right sides of the connecting rod 9. The warning sign 6 is hinged to the hanging lugs 13 so that it hangs down naturally under the action of gravity.

[0034] On the pillar 1.1, a first camera 14 and a second camera 15 are installed one in front of the other and one behind the protective box 3, respectively, to monitor the road conditions in two opposite directions at the intersection.

[0035] As shown in Figures 5 to 8: A fixed roller 16 and a movable roller 17 are installed inside the protective box 3. The fixed roller 16 is connected to the protective box 3 through a fixed bracket 16.1. The movable roller 17 is connected to the protective box 3 through an "L"-shaped rod 18. The movable roller 17 is connected to the corner of the "L"-shaped rod 18. The first end of the "L"-shaped rod 18 is hinged to the protective box 3. The second end of the "L"-shaped rod 18 is connected to the elastic push-pull assembly. The elastic push-pull assembly drives the "L"-shaped rod 18 to swing, causing the movable roller 17 to approach the fixed roller 16.

[0036] The lifting rod 19 is held between the fixed roller 16 and the movable roller 17. The slider 20 at the bottom of the lifting rod 19 slides in cooperation with the guide rail 21 in the protective box 3 to ensure that the lifting rod 19 rises and falls smoothly. A trigger block 22 is installed on the top of the lifting rod 19. Two proximity switches 23 are installed one above the other in the protective box 3. The two proximity switches 23 correspond to the first camera 14 and the second camera 15, respectively.

[0037] The outer layer of the fixed roller 16 and the movable roller 17 is a rubber layer to increase the friction when in contact with the lifting rod 19.

[0038] A driven gear 24 is mounted on the shaft of the fixed roller 16; a transmission shaft 25 is provided inside the protective box 3, on which a driving gear 26 and a driven pulley 27 are mounted. The driving gear 26 meshes with the driven gear 24, and the driven pulley 27 is connected to the driving pulley 28 on the drive motor 2 via a belt.

[0039] The elastic push-pull assembly includes a pull rod 29, a tension spring 30, and a collection box 31. The tail of the pull rod 29 is slidably inserted into the collection box 31. The tension spring 30 connects the pull rod 29 and the collection box 31. The pull ring 32 at the head of the pull rod 29 is movably sleeved on the second rod of the "L"-shaped rod 18. Under the tension of the tension spring 30, the "L"-shaped rod 18 always tends to swing in one direction, thereby driving the movable roller 17 to press tightly against the fixed roller 16. The two work together to clamp the lifting rod 19.

[0040] The complete working process and principle of this invention are as follows:

[0041] When the device is started, drive motor 2 begins to rotate alternately in both directions. The rotation of drive motor 2 produces two parallel actions:

[0042] First, the drive motor 2 drives the first rocker arm 7 to swing. Since the first rocker arm 7 and the second rocker arm 8, together with the connecting rod 9, form a crank-rocker mechanism, the swing of the first rocker arm 7 will drive the connecting rod 9 to move back and forth. The connecting rod 9, in turn, drives the support plate 10 and the display 4 mounted on it to tilt forward or backward as a whole. During this process, the counterweight 12 mounted on the lower end of the display 4 always points towards the ground under the action of gravity, which makes the display 4 automatically rotate on the rotating seat 11 of the support plate 10. No matter how the support plate 10 is tilted, the screen of the display 4 always remains upright, ensuring that pedestrians or drivers can clearly and without inversion view the displayed content at any tilt angle.

[0043] Second, while the drive motor 2 rotates, it transmits power to the transmission shaft 25 through the driving pulley 28, belt, and driven pulley 27. When the transmission shaft 25 rotates, the driving gear 26 on it drives the driven gear 24 meshing with it to rotate, thereby driving the fixed roller 16 to rotate. Because the movable roller 17 is always in close contact with the fixed roller 16 and clamps the lifting rod 19 under the action of the tension spring 30 of the elastic push-pull assembly, the rotation of the fixed roller 16 drives the lifting rod 19 to move up and down under the guidance of the guide rail 21 through friction.

[0044] The forward and reverse rotation of the drive motor 2 is synchronized with the tilt direction of the display 4 and the movement direction of the lifting rod 19. When the drive motor 2 rotates forward, it drives the first rocker arm 7 to swing forward, causing the display 4 to tilt forward (towards the first camera 14). At the same time, the transmission system drives the fixed roller 16 to rotate forward, causing the lifting rod 19 to move upward. When the trigger block 22 at the top of the lifting rod 19 moves to the top, it triggers the proximity switch 23 above. After the proximity switch 23 is triggered, the control circuit immediately connects the video transmission line between the first camera 14 and the display 4. At this time, the display 4 begins to play the image of the intersection ahead captured by the first camera 14.

[0045] Conversely, when the drive motor 2 reverses, driving the first rocker arm 7 to swing backward, causing the display 4 to tilt backward (towards the second camera 15), the fixed roller 16 also reverses, driving the lifting rod 19 to move downward. When the trigger block 22 moves to the bottom and triggers the proximity switch 23 below, the circuit switches, and the display 4 begins to play the image of the intersection behind captured by the second camera 15.

[0046] Through the above-mentioned interconnected design, this invention achieves intelligent information display where "the real-time image from the camera in the direction the display is tilted corresponds to." This solves the problem of vehicles behind being unable to observe the signal when large vehicles obstruct it, allowing following vehicles to directly observe the display screen tilted in their direction to assess road conditions.

[0047] Furthermore, when the device is in operation, the warning light strips 5 distributed around the outer ring of the display 4 can remain constantly lit or flash according to the signal status, serving a basic warning function. The warning sign 6, hinged to the lugs 13 of the support plate 10, naturally hangs downwards towards the ground due to its lower center of gravity. Regardless of the display's tilt, it maintains a stable posture, providing clear and stable text or graphic warnings (such as "Caution" or "Slow Down") to nearby pedestrians and non-motorized vehicles. Especially in emergency situations, the sign and light strips can be controlled to enhance the warning effect through high brightness or strobe, reminding all road users at the intersection to take evasive action.
