Description

Technical Field

[0001] The invention relates to the technical field of traffic warning, and in particular to a road blind spot traffic warning device. Background Art

[0002] Traffic warning is a way of conveying traffic rules, potential dangers and other important traffic information to road users (including drivers, pedestrians, cyclists, etc.) through various signals, signs, markings and other means. It also refers to the use of graphic symbols and text to convey specific information, and is used to manage traffic, indicate driving directions, and ensure smooth roads and safe driving. Traffic warnings mainly include traffic lights, traffic signs and traffic markings, which are used to issue warnings or prompts to traffic participants to urge them to pay attention to safety and comply with traffic rules.

[0003] A Chinese invention patent with publication number CN114775472B discloses a road condition blind spot traffic warning device based on computer vision, comprising: a computer vision device and a warning plate installed on the side wall of an L-shaped plate, a groove is provided on the top of the L-shaped plate, a reciprocating screw is rotatably connected to the inner wall of the groove, a motor is fixedly connected to the side wall of the L-shaped plate through a bracket, the movable end of the motor is fixedly connected to one end of the reciprocating screw, a slider is threadedly connected to the side wall of the reciprocating screw, the side wall of the slider is slidably connected to the inner wall of the groove, a vertical plate is fixedly connected to the lower end of the slider, a cavity is provided in the vertical plate, and a plurality of rotating shafts are rotatably connected to the inner wall of the cavity. When dust accumulates more on the warning plate of the present invention, the resistance of the photoresistor is small, and then the motor will be fed with current to rotate, and then the slider will drive the vertical plate to drive the plurality of first bristles to slide back and forth on the computer vision device and the side wall of the warning plate, and then the dust on the computer vision device and the side wall of the warning plate is automatically and preliminarily cleaned.

[0004] In addition, since blind spot traffic warning devices are generally installed on both sides of the road, when a vehicle loses control, the vehicle may collide with the traffic warning device. If the structure of the traffic warning device is not strong enough or the installation is not secure, the traffic warning device may be damaged or tilted. When the traffic warning device tilts, the angle of the internal laser detection will change to a certain extent, which will affect the warning effect of the traffic warning device and ultimately easily cause a secondary traffic accident. Therefore, the computer vision-based blind spot traffic warning device disclosed in Chinese invention patent CN114775472B cannot protect the traffic warning device or guarantee the accuracy of the detection of the traffic warning device.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example:

[0035] See attached Figures 1 to 8As shown, a road blind spot traffic warning device includes a protective shell 1 and a mounting base 2, the mounting base 2 is fixedly connected to the lower surface of the protective shell 1, the upper surface of the mounting base 2 is fixedly connected to a warning pile 3, the top of the mounting base 2 is provided with an anti-collision mechanism 4, and the outer side of the protective shell 1 is symmetrically provided with a stabilizing mechanism 5.

[0036] Furthermore, the anti-collision mechanism 4 includes a slide plate 41 symmetrically penetrated and slidably connected to the inner wall of the protective shell 1, the end of the slide plate 41 away from the protective shell 1 is fixedly connected to a bracket 42, the end of the bracket 42 away from the slide plate 41 is fixedly connected to an arc groove plate 43, the arc groove plate 43 is arranged in a circular array on the inner wall of the side away from the protective shell 1 and is rotatably connected to rubber rollers 44, a pressure detector is installed inside the rubber roller 44, fixed blocks 45 are symmetrically fixedly connected to the inner wall of the protective shell 1, a fixed rod 46 is rotatably connected between the two fixed blocks 45, a gear 1 47 is symmetrically fixedly connected to the outer wall of the fixed rod 46, and a gear 2 48 is fixedly connected to the middle outer wall of the fixed rod 46.

[0037] The rubber rollers 44 are rotated in an arc-shaped arrangement inside the arc-shaped groove plate 43, so that the impact force is dispersed and the impact direction of the impact object is changed at the same time.

[0038] Furthermore, the anti-collision mechanism 4 also includes a tooth plate 49 fixedly connected to the upper surface of the slide plate 41, the tooth plate 49 and the gear 47 are meshed with each other, and a limited sliding groove 410 is symmetrically provided on the inner wall of the protective shell 1, and the interior of the limited sliding groove 410 is slidably connected with a double tooth plate 411, and the double tooth plate 411 is fixedly connected with a tooth plate 2 412 at one end close to the slide plate 41, and the tooth plate 2 412 and the gear 2 48 are meshed with each other. A fixed plate 413 is symmetrically fixedly connected to the inner wall of the protective shell 1, and a sliding rod 414 is slidably connected to the interior of the fixed plate 413 in a linear array, and a spring 415 is sleeved on the outer wall of the sliding rod 414, and the two ends of the spring 415 are respectively fixedly connected to the fixed plate 413 and the sliding rod 414, and the end of the sliding rod 414 close to the middle of the protective shell 1 is fixedly connected with a single tooth plate 416, and the single tooth plate 416 and the double tooth plate 411 are meshed with each other.

[0039] The impact force is converted through the friction between the double-tooth plate 411 and the single-tooth plate 416, thereby weakening the impact effect on the impact object, avoiding the problem that the impact force cannot be quickly eliminated when the elastic device is used for buffering.

[0040] Furthermore, the stabilizing mechanism 5 includes a limiting slide groove 51 symmetrically opened on the outer wall of the protective shell 1, and a slider 52 is slidably connected inside the limiting slide groove 51. The friction between the slider 52 and the limiting slide groove 51 is greater than the self-weight of the slider 52. A limiting plate 53 is symmetrically fixedly connected to the outer wall of the protective shell 1, and a telescopic rod 54 is fixedly connected to the lower surface of the limiting plate 53. There is an electrical connection between the telescopic rod 54 and the pressure detector installed inside the rubber roller 44, and the pressure detector installed inside the rubber roller 44 drives the telescopic rod 54 to work.

[0042] The triangular structure formed by the insertion of the rod 55 into the soil and the unfolding of the support plate 59 avoids the problem of angle deviation of the device after being hit.

[0043] The following is the working process and principle of the above embodiment:

[0044] The initial state is as follows: gear 1 47 is at one end of tooth plate 1 49 close to the middle of protective shell 1, gear 2 48 is at the top of tooth plate 2 412, fixed block 45 is in an unstretched state, telescopic rod 54 is in an unstretched state, and slider 52 is at the top of limiting slide groove 2 51.

[0045] The working steps are as follows:

[0046] When an external object hits the warning pile 3, the impacting object will first resist the rubber roller 44, so that the rubber roller 44 guides the impacting object by rotating itself, so that the direction of the impacting object changes, and then the impact force generated by the impacting object can be dispersed, and finally the impact force is reduced. At the same time, there is still a part of the impact force that is perpendicular to the rubber roller 44, so that the rubber roller 44 drives the arc groove plate 43 to move toward the side close to the protective shell 1, and the rubber roller 44 drives the bracket 42 to move toward the side close to the protective shell 1, and then the bracket 42 drives the slide plate 41 to slide toward the inside of the protective shell 1. During the movement of the slide plate 41, the slide plate 41 drives the tooth plate 1 49 to move synchronously, so that the tooth plate 1 49 drives the gear 1 47 meshing with it to rotate, so that the gear 1 47 drives the fixing rod 46 to rotate between the two fixing blocks 45, so that the fixing rod 46 drives the gear 2 48 to rotate synchronously.

[0047] When the gear 2 48 rotates, the gear 2 48 drives the toothed plate 2 412 meshing therewith to move toward the top of the protective shell 1, so that the toothed plate 2 412 drives the double toothed plate 411 to move toward the top of the protective shell 1 inside the limiting slide groove 1 410, so that the double toothed plate 411 contacts the single toothed plate 416, so that the single toothed plate 416 moves toward the side close to the fixed plate 413, so that the fixed plate 413 drives the slide bar 414 to slide inside the fixed plate 413 toward the side away from the double toothed plate 411, and then the slide bar 414 drives the spring 415 to stretch toward the side away from the double toothed plate 411, so that the double toothed plate 411 is in the process of moving. , so that the single tooth plate 416 contacts the double tooth plate 411 under the elastic action of the sliding rod 414, thereby increasing the friction between the double tooth plate 411 and the single tooth plate 416, and reducing the impact force through the friction force generated by the relative movement between the double tooth plate 411 and the single tooth plate 416, thereby avoiding the direct collision of the impact object with the warning pile 3, improving the protection effect of the warning pile 3, and ensuring the service life of the warning pile 3. The rubber roller 44 arranged in an arc shape inside the arc groove plate 43 not only achieves the dispersion of the impact force, but also achieves the change of the movement direction of the impact object, thereby reducing the intensity of the impact force.

[0048] When the impact object collides with the rubber roller 44, the pressure detection device installed inside the rubber roller 44 controls the telescopic rod 54 to start to extend downward, so that the telescopic end of the telescopic rod 54 drives the plug rod 55 to slide vertically downward inside the slider 52, so that the plug rod 55 drives the slider 52 to slide vertically downward inside the limiting slide groove 2 51 through the friction between the plug rod 55 and the slider 52. When the slider 52 slides to the lowest end of the limiting slide groove 2 51, the slider 52 no longer moves downward. At this time, the telescopic rod 54 drives the baffle 56 to move to the side close to the slider 52 through the plug rod 55, so that the baffle 56 collides with the top of the slider 52, and then the plug rod 55 drives the hinge block 2 58 to continue to move vertically downward, so that the hinge block 2 58 drives the adjustment rod 512 hinged thereto to start rotating, so that the bottom end of the adjustment rod 512 moves away from the hinge block 2 58 with the hinge block 2 58 as the axis. One side of the insertion rod 55 flips, so that the adjustment rod 512 drives the bottom end of the support plate 59 to flip synchronously with the hinge block 57 as the axis, so that the support plate 59 drives the resistance plate 511 to flip synchronously through the hinge rod 510 rotatably connected thereto, and at the same time, the resistance plate 511 always remains in a vertical state under the action of its own gravity. When the telescopic rod 54 is no longer extended, the insertion rod 55 is inserted into the ground, and at the same time, the resistance plate 511 is in contact with the ground. The triangular structure formed by the insertion of the insertion rod 55 into the soil and the expansion of the support plate 59 improves the stability of the device when it is hit, avoids the problem of angle deviation after the device is hit, and prevents the problem of tilt of the detection laser due to the tilt of the warning pile 3, thereby ensuring the accuracy of the detection result of the warning pile 3, and ultimately providing safety for vehicles and pedestrians.
