Description

Technical Field

[0001] The utility model belongs to the technical field of traffic safety warning equipment, and in particular relates to a solar road sign warning light. Background Art

[0002] The highway edge contour induction lights are a subsystem of the highway fog driving safety induction system. Due to the characteristics of highways such as large traffic volume, high speed, and full closure, vehicles are required not to slow down or stop at will. At night or in rainy and foggy weather, the visibility of the highway is reduced, which is easy to cause serious traffic accidents such as multi-vehicle chain rear-end collisions. Therefore, it is necessary to turn on the edge contour induction lights to indicate the road contour, improve road visibility, effectively guide the flow of traffic, assist drivers to understand the road conditions ahead, and avoid traffic accidents.

[0003] In order to improve the clarity of road contours, in rainy and foggy weather with low visibility, warning lights are often made to flash synchronously at a specific frequency, so as to use dynamic lights to remind drivers to drive carefully, mark the road line shape, and guide vehicles forward. However, in the prior art, the flashing of warning lights requires programming using a controller to control the warning light switch at a fixed time so that the lights have an intermittent flashing effect. However, cars travel at a high speed on highways, and the lights may be turned off during the flashing process, which may cause safety hazards to the vehicles. In addition, frequent switching operations will cause a large operating load on the light circuit and bulb, resulting in a reduced service life of the warning lights.

[0004] Therefore, we propose a solar road sign warning light to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1-4 A solar road sign warning light includes a support frame 1 fixedly mounted on the ground, a lampshade 2 is mounted on the top of the support frame 1, the support frame 1 is installed at intervals along the highway guardrail, and the lampshade 2 needs to be installed corresponding to the direction of driving to achieve the effect of reminding the driver.

[0025] The support frame 1 includes a mounting plate 11, which is fixed on a road foundation. A support rod 12 is rotatably arranged on the mounting plate 11. A damping structure is arranged between the mounting plate 11 and the support rod 12. The lateral angle of the lampshade 2 can be controlled by rotating the support rod 12. Under the action of the damping structure, the support rod 12 maintains a stable position without external force, so that the installation position of the warning light can be adjusted easily. A C-shaped frame 13 is installed on the top of the support rod 12. The C-shaped frame 13 is rotatably connected to the lampshade 2. The longitudinal angle of the lampshade 2 can be adjusted by rotating the lampshade 2 to further adjust the warning light. A locking bolt 14 is passed through the C-shaped frame 13. After the position of the lampshade 2 is adjusted, the lampshade 2 is fixed to the C-shaped frame 13 by the locking bolt 14 to ensure that the angle of the warning light remains at a suitable position.

[0026] The damping structure includes a slideway opened at the bottom end of the support rod 12, a ball 15 is movably arranged in the slideway, a spring 16 is arranged between the ball 15 and the slideway, and a plurality of hemispherical grooves 17 adapted to the ball 15 are arranged in the mounting plate 11. Under normal conditions, the ball 15 extends out of the slideway under the elastic force of the spring 16, so that the ball 15 enters the groove 17. Under the action of the ball 15, the support rod 12 and the mounting plate 11 are circumferentially limited to ensure The support rod 12 does not deviate. When the angle of the warning light needs to be adjusted, the support rod 12 is rotated and a circumferential force is applied to the support rod 12, so that the support rod 12 acts on the ball 15 when it rotates. The surface of the ball 15 is a curved surface, and when it abuts against the slot 17, the ball 15 retracts into the slideway. Then the support rod 12 and the mounting plate 11 can be easily rotated until they are adjusted to a suitable position. The ball 15 pops out again and extends into the slot 17 under the action of the spring 16.

[0027] A lamp body 3 capable of emitting light is arranged in the lampshade 2, a diffuser plate 4 is fixedly arranged at the outer end of the lampshade 2, the light generated by the lamp body 3 is irradiated on the diffuser plate 4, and is irradiated out through the diffuser plate 4, a movable ring 5 is axially slidably arranged in the lampshade 2, a plurality of guide strips 10 are axially arranged on the inner wall of the lampshade 2, a notch 52 matched with the guide strip 10 is opened on the outer peripheral surface of the movable ring 5, with the cooperation of the guide strip 10 and the notch 52, the movable ring 5 is limited so that the movable ring 5 can slide axially in the lampshade 2, and at the same time, the circumferential deflection of the movable ring 5 is restricted.

[0028] Reference Figure 1 , 5 and 6, a spring 6 is provided between the movable ring 5 and the diffuser plate 4, a lens 51 is fixedly installed in the movable ring 5, the lens 51 is located between the diffuser plate 4 and the lamp body 3 and is coaxially installed, the light emitted by the lamp body 3 needs to pass through the lens 51 to reach the diffuser plate 4, as the light passes through the lens 51, the light will be refracted, the light path will be changed, and when the lens 51 is axially displaced with the movable ring 5, the emission angle of the light will change, when the light of different irradiation angles is irradiated on the diffuser plate 4, the brightness displayed by the diffuser plate 4 will change accordingly, and the brightness change of the diffuser plate 4 will make the warning light realize intermittent flashing effect, so as to use dynamic lights to remind the driver to drive carefully, mark the road line shape, and guide the vehicle forward.

[0029] The above technical solution realizes dynamic flashing of light by changing the position of the lens 51 in cooperation with the diffuser plate 4. Since the lamp body 3 is in a constantly on state, it has higher stability compared to the frequent switching warning light in the prior art, which is beneficial to extending the service life of the lamp body 3. In addition, by changing the refraction angle of the light of the lamp body 3, the brightness can be changed, and the light will not disappear completely, which is safer.

[0030] Reference Figure 1-2 The diffuser plate 4 includes a light-transmitting plate 41, on which a plurality of transparent diffuser balls 42 are evenly distributed. When light is irradiated vertically onto the diffuser plate 4, the light passes vertically through the diffuser balls 42 and maintains a high-brightness state. After the position of the lens 51 changes, the light refraction angle changes, and the light is irradiated obliquely onto the diffuser balls 42. The light undergoes secondary refraction and diffuse reflection on the diffuser balls 42, which reduces the display brightness of the diffuser plate 4. The reciprocating motion of the lens 51 switches the diffuser plate 4 back and forth between high brightness and low brightness.

[0031] A driving mechanism for driving the movable ring 5 to slide axially is arranged in the lampshade 2. The movable ring 5 can be adaptively controlled to move axially back and forth through the driving structure.

[0032] Reference Figure 1 , 5 The rotating ring 7 is provided with a gear ring 71 on the outer circumference of the rotating ring 7, and a motor 9 is fixedly mounted outside the lampshade 2, and a gear 91 is fixedly mounted on the output end of the motor 9, and the gear 91 is meshed with the gear ring 71, and the gear 91 is driven to rotate by the motor 9, so as to drive the rotating ring 7 to rotate, thereby driving the movable ring 5 to move axially back and forth, controlling the movement of the lens 51, and realizing the change of the light.

[0033] Through the environment and traffic condition monitoring equipment, the environmental information such as road visibility, weather phenomena, atmospheric temperature, relative humidity, air pressure, wind direction, wind speed, precipitation and the traffic information such as vehicle flow, vehicle running speed and driving direction are collected in real time. When the visibility is less than 600m, the motor 9 is started to make the warning light flash synchronously at a specific frequency, and the driver is reminded to drive carefully through dynamic lights, the road line shape is marked, and the vehicle is guided forward.

[0034] It also includes a photosensitive sensor 21 installed on the lampshade 2, wherein the photosensitive sensor 21 is electrically connected to the lamp body 3. The ambient brightness is detected by the photosensitive sensor 21. After the ambient brightness decreases, the lamp body 3 is turned on to induce the road contour. Under the action of the photosensitive sensor 21, the lamp body 3 will only be turned on when the ambient brightness is low, thereby reducing energy waste.

[0035] Working principle:

[0036] Warning lights are installed at intervals along the highway guardrails, and the ambient brightness is detected by a photosensitive sensor 21. When the ambient brightness decreases, the lamp body 3 is turned on to induce the road profile. The visibility of the road section is collected in real time through the environment and traffic condition monitoring equipment. When the visibility is less than 600m, the motor 9 is started, and the gear 91 is driven by the motor 9 to rotate, driving the rotating ring 7 to rotate, and the rotating ring 7 drives the magnet 8 to rotate. When the positions of the magnet 8 on the rotating ring 7 and the magnet 8 on the movable ring 5 correspond, the movable ring 5 is driven away from the rotating ring 7 under the magnetic repulsion between the magnets 8, and after the positions of the magnet 8 on the rotating ring 7 and the magnet 8 on the movable ring 5 are misaligned, the movable ring 5 is elastically moved. The lens 51 is reset under the action of the spring 6, and the lens 51 reciprocates axially with the movable ring 5. When the light passes through the lens 51, the light is refracted to change the light path, and when the lens 51 is displaced axially, the emission angle of the light will change. When the light is vertically irradiated on the diffuser plate 4, the light passes vertically through the diffuser ball 42 to maintain a high-brightness state. After the position of the lens 51 changes, the refraction angle of the light changes, and the light is obliquely irradiated on the diffuser ball 42. The light is refracted twice and diffusely reflected on the diffuser ball 42, which reduces the display brightness of the diffuser plate 4. Through the reciprocating motion of the lens 51, the diffuser plate 4 switches back and forth between high brightness and low brightness to achieve a dynamic flashing effect.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
