Description

Technical Field

[0001] This invention relates to the field of intelligent traffic guidance technology, and in particular to a synchronous guidance guardrail system for one-way curves. Background Technology

[0002] When driving on a highway curve, the driver's line of sight is limited, making it difficult to see the full extent and curvature of the curve. Existing driving environments and traffic sign systems do not provide sufficient information, making it difficult for drivers to obtain detailed information about the specific lane path and curve shape in advance. This limited visibility leads to the following drawbacks and challenges: 1. Insufficient warning capability: Drivers cannot receive enough warning information before entering a curve, making it difficult to accurately judge the sharp angle and curvature of the curve. 2. Inability to accurately grasp the lane path: Lacking specific lane path information, drivers often cannot accurately grasp the position and direction of the curve. This may cause the vehicle to deviate from the appropriate driving line, resulting in unsafe driving behavior and potential collision risks. 3. Impact on driving confidence: Limited visibility negatively impacts driver confidence. Uncertainty about the specific shape and curvature of the curve may cause drivers to feel tense or anxious, affecting their ability to maintain normal vehicle control and respond to unexpected situations.

[0003] To address the aforementioned issues, this application provides a synchronous guide guardrail system for one-way curves, which can provide intuitive curve information, allowing drivers to have a clearer understanding of the curve curvature, make timely driving adjustments, and improve driving safety. Summary of the Invention

[0004] This invention provides a synchronous guide railing system for one-way curves to solve existing technical and safety problems.

[0005] This invention provides a synchronous guide railing system for one-way curves, comprising n railing posts and m railing heightening devices. The heightening devices are positioned at the top of the railing posts, and each heightening device is equipped with a guide display box and an electrical control system. The electrical control system is located inside the heightening device and electrically connected to the guide display box. The guide display box displays the curve curvature path. The guide display box is set with a corresponding angle based on the curve direction and curvature of the road, ensuring that the guide direction presented by the guide display box aligns with the curve direction. Where m ≦ n and is a positive integer, and n is set according to the curve length.

[0006] A further improvement is that the guardrail raising device includes a raising connection component and a raising device base; the raising connection component is embedded in the guardrail post, the raising connection component is detachably connected to the raising device base, and the upper part of the raising device base is detachably connected to the guide display box.

[0007] A further improvement is that the heightening connection assembly includes an outer sleeve and an inner sleeve, the outer sleeve being fixed inside the guardrail post, and the inner sleeve being embedded inside the outer sleeve; the top of the inner sleeve is connected to the base of the heightening device.

[0008] A further improvement is that the guide display box includes a housing and an angle adjustment assembly; the housing is a chamber with an opening on one side, a semi-transparent lens is provided on the opening side of the housing, the inner surface of the housing is opaque and also has semi-transparent lenses; a semi-transparent lens is provided on the bottom surface of the housing, a one-way mirror is disposed inside the housing, and the one-way mirror is connected to the top and bottom surfaces of the housing via the angle adjustment assembly; the angle adjustment assembly is used to adjust the rotation angle of the one-way mirror; when the angle adjustment assembly is not adjusting the angle, the one-way mirror and the semi-transparent lens on the opening side of the housing are parallel; a first LED is disposed between the one-way mirror and the semi-transparent lens on the opening side of the housing, wherein the inner length of the housing is... , It is a positive integer.

[0009] A further improvement is that the thickness of the single-sided reflector is δ, and the length of the single-sided reflector is... ,in The distance d between the side of the single-sided reflector and the inner wall of the box is ; where .

[0010] A further improvement is that a second LED light strip is provided on the inner wall of the box, and the second LED light strip wraps around the inner side, top and bottom of the box and connects end to end.

[0011] The beneficial effects of this invention are as follows: 1. By installing a guide display box at the top of the guardrail post, the system can display the curvature path of the curve and set the angle according to the curvature and direction of the curve, so that the guidance direction presented by the guide display box is consistent with the curvature direction of the curve. This provides effective guidance, helps drivers accurately grasp the curve path, and thus increases driving safety. 2. The guardrail heightening device includes a heightening connection component, an electrical control system housing, and a heightening device base. The heightening connection component embedded in the guardrail post and the electrical control system housing control the raising and lowering of the heightening device base, achieving multi-level height adjustment to adapt to different curves with varying slopes. This allows the guardrail height to be reasonably set at an appropriate position according to specific road conditions and needs, providing a better guardrail guidance effect. 3. The angle adjustment component inside the guide display box can adjust the rotation angle of the single-sided reflector. By adjusting the angle of the single-sided reflector, the corresponding angle between the guide display box and the curve can be achieved. This ensures that drivers receive consistent guidance information when observing the guide display box from different angles, increasing the accuracy of the driver's understanding and reaction to curves. In this invention, the vehicle headlights illuminate the outermost semi-transparent lens of the housing at night, thus reducing glare caused by the single-sided reflector inside the housing. The semi-transparent lens within the display housing is designed to scatter and disperse light, ensuring more even illumination of the driver's eyes. This reduces direct glare and minimizes the degree of glare. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the following description is provided in conjunction with... Figures 1 to 8 The present invention describes a one-way curve synchronous guide railing system.

[0025] like Figure 1 As shown, this invention provides a synchronous guide railing system for one-way curves, comprising n railing posts 1 and m railing heightening devices, wherein the railing heightening devices are disposed at the top of the railing posts 1, and as shown... Figure 2 As shown, each of the guardrail raising devices is equipped with a guide display box and an electrical control system. The electrical control system is located inside the raising device and is electrically connected to the guide display box. The guide display box is used to display the curvature path of the curve. The guide display box is set with a corresponding angle according to the curvature and direction of the curve, so that the guide direction presented by the guide display box is consistent with the curvature direction of the curve. Wherein, m≦n and is a positive integer, and n is set according to the length of the curve.

[0026] Further improvements include, for example Figure 3As shown, the guardrail raising device includes a raising connection assembly, a raising device base 12, and an electrical control system housing 13. The raising connection assembly is embedded in the guardrail post 1, and the raising connection assembly is detachably connected to the electrical control system housing 13. The electrical control system housing 13 is equipped with an electrical control system that can control the raising and lowering of the raising device base, achieving multi-level height adjustment to adapt to different curved roads with varying slopes. The electrical control system housing 13 is detachably connected to the raising device base 12, and the upper part of the raising device base 12 is detachably connected to the guide display box.

[0027] A further improvement is that the heightening connection assembly includes an outer sleeve 9 and an inner sleeve 10. The outer sleeve 9 is fixed inside the guardrail post 1. The outer sleeve 9 can be set to different heights according to actual needs, reasonably setting the height of the guardrail at an appropriate position to provide a better guiding effect. The inner sleeve 10 is embedded inside the outer sleeve 9; the top of the inner sleeve 10 is connected to the heightening device base 12. Figure 3 As shown, in an optional embodiment of this application, the upper side of the inner sleeve 10 is provided with a snap-fit ​​limiting tooth 11, and the upper end of the outer sleeve 9 is provided with a limiting groove 91. During installation, the inner sleeve 10 is embedded in the outer sleeve 9, and the snap-fit ​​limiting tooth 11 is snapped into the limiting groove 91.

[0028] A further improvement is, such as Figure 2 As shown, the guide display box includes a housing 3 and an angle adjustment component 7. The housing 3 is a chamber with an opening on one side. A semi-transparent lens 4 is provided on the opening side of the housing 3. The inner surface of the housing 3 is opaque and also has semi-transparent lenses. A semi-transparent lens is provided on the bottom surface of the housing 3. A one-sided reflector 5 is disposed inside the housing 3. The one-sided reflector 5 is connected to the top and bottom surfaces of the housing 3 via the angle adjustment component 7. The angle adjustment component 7 is used to adjust the rotation angle of the one-sided reflector 5. When the angle adjustment component 7 is not adjusting the angle, such as... Figure 5 As shown in Figure A, the single-sided reflector 5 is parallel to the semi-transparent lens 4 on the opening side of the housing 3; a first LED 6 is disposed between the single-sided reflector 5 and the semi-transparent lens 4 on the opening side of the housing 3, wherein the inner length of the housing 3 is... , It is a positive integer. For example... Figure 4As shown, the angle adjustment assembly 7 includes an angle adjustment knob 71, an angle adjustment plate 72, and an adjustment coupling 73. The angle adjustment knob 71 drives the angle adjustment plate to rotate via the adjustment coupling. The adjustment coupling 73 passes through the top cover 8 of the housing and connects to the bottom surface of the housing 3. The angle adjustment plate 72 is bonded and fixed to the back of the single-sided reflector 5. The rotation of the angle adjustment plate 72 drives the single-sided reflector 5 to rotate, and rotates around the adjustment coupling 73, thereby realizing the angle adjustment of the single-sided reflector 5. In an optional embodiment of this application, a limit structure is provided in the angle adjustment knob 71. After angle adjustment, the limit structure automatically limits the angle to ensure that the single-sided reflector 5 does not change at the current angle. The angle adjustment knob 71 is also provided with a reset structure. When angle adjustment is required again, operating the reset structure will release the limitation of the limit structure, thereby realizing the reset. In the solution of this application, the reset state of the single-sided reflector 5 is to keep the single-sided reflector 5 parallel to the open-side semi-transparent lens 4.

[0029] The thickness of the single-sided reflector 5 is δ, and the length of the single-sided reflector 5 is... ,in The distance d between the side of the single-sided reflector 5 and the inner wall of the housing 3 is given by the value of d. In this way, the single-sided reflector 5 will not rub against or collide with the inner wall of the housing 3 when the angle is adjusted and rotated.

[0030] A further improvement is that a second LED light strip is installed on the inner wall of the housing 3. The second LED light strip wraps around the inner side, top, and bottom surfaces of the housing 3, with the ends connected. The first LED and the second LED light strip are electrically connected to the electrical control system, and simultaneously electrically connected to the solar panel on the top surface of the housing. During the daytime when there is sufficient sunlight, the first LED and the second LED light strip are powered by the solar panel on the top surface of the housing.

[0031] In an optional embodiment of this application, a semi-transparent mirror with 20% transmittance and a single-sided reflector 5 with 95% reflectivity are selected. Testing shows that 100% of the light emitted by the first and second LED strips reaches the single-sided reflector 5. The single-sided reflector 5 reflects 95% of the light to the open-side semi-transparent mirror 4. The open-side semi-transparent mirror 4 transmits 19% of the light and simultaneously reflects 76% of the light back to the single-sided reflector 5. The single-sided reflector 5 reflects 72.2% of the light back to the open-side semi-transparent mirror 4. The open-side semi-transparent mirror 4 transmits 14.44% of the light and simultaneously reflects 57.76% of the light back to the single-sided reflector 5. This process repeats multiple times, such as... Figure 6 As shown, the light transmitted from the semi-transparent lens 4 on the opening side of the guide display box 3 can be observed to extend the light source of the first LED 6 into an arc that is the same as the curve of the bend.

[0032] In this application, the curvature displayed by the guide display box varies depending on the angle at which the single-sided reflector 5 is set; for example: Figure 5 In Figure A, the single-sided reflector 5 is positioned parallel to the semi-transparent lens 4 on the opening side of the guide display box 3, with an angle of 0° between them. The resulting display effect is as follows: Figure 6 As shown in Figure A, it extends infinitely inward in a straight line. Figure 5 In Figure B, the single-sided reflector 5 is positioned at a 30° angle with the semi-transparent lens 4 on the open side, resulting in the following display effect: Figure 6 As shown in Figure B, it presents an arc that curves counterclockwise; Figure 5 In Figure C, the single-sided reflector 5 is positioned at a 30° angle with the open-side semi-transparent lens 4, resulting in the following display effect: Figure 6 As shown in Figure C, it presents an arc that curves in a clockwise direction.

[0033] like Figure 7 As shown, three points M1, M2, and M3 are taken on the curve. M1M2 and M2M3 are two curve arcs of equal length. When the vehicle drives from point M2 to point M3, the angle of the tangent is... Compared to the angle of the tangent when driving from point M1 to point M2. It should be smaller; there is a tangent relationship between curvature and tangent angle, meaning that as the tangent angle increases, the curvature also increases, and vice versa. A larger curvature indicates a more pronounced curve at that point, requiring a smaller turning radius; a smaller curvature indicates a less pronounced curve at that point, requiring a larger turning radius. This means that... Figure 7 In the curve, M1M2 has a greater curvature than M2M3. Therefore, corresponding to the characteristics of this curve, the angle of the single-sided reflector 5 on the guardrail at point M1 is set to the left included angle β1, and the angle of the single-sided reflector 5 on the guardrail at point M2 is set to the left included angle β2, where β1 > β2. As shown in Table 1, the curvature k of the curve is directly proportional to the angle β of the single-sided reflector 5.

[0034] Table 1. Correspondence between imaging curvature and orientation of the guide display box at 5 angles with different single-sided reflectors.

[0035]

[0036] In the guardrail system provided in this application, the state of the guidance display box is set according to the different curvature k of the curve, which is the angle between the single-sided reflector and the open-side semi-transparent lens. This application aims to provide drivers with curve warnings in advance. Therefore, when setting the guidance display box of the guardrail, the effect (imaging effect) presented by the guidance display box in each area after entering the curve is the curvature k setting of the next area.

[0037] like Figure 8 As shown, in an optional embodiment of this application, a certain curve is selected and divided into four regions according to its curvature characteristics, namely region P1, region P2, region P3, and region P4; based on the relationship between the curve curvature k and the angle of the single-sided reflector 5 of the guide display box, Table 2 can be obtained:

[0038] Table 2. Relationship between the angle of the single-sided reflector and the number of guardrails at different curvature positions of the curve.

[0039]

[0040] As can be seen from Table 2, the single-sided reflector and the semi-transparent lens on the open side of the guide display box in area P1 have a large angle, which reflects the road curvature of the next area, namely area P2. Figure 8 It can also be seen that the road curvature in region P2 is greater than that in region P1. Similarly, as the curvature of the curve decreases (becomes straighter), the angle between the single-sided reflector and the semi-transparent lens on the opening side in each region decreases to reflect the state of the next region.

[0041] Therefore, the guardrail system provided in this application can provide effective guidance for different curvatures of curves, helping drivers to accurately grasp the curved path of curves, thereby increasing driving safety.

[0042] It is worth noting that, in nighttime applications, to prevent the guidance display box from glaring at the driver under vehicle headlights, this application selects a reflective material with good anti-glare properties for the single-sided reflector 5. Simultaneously, by adjusting the angle, direct light entering the driver's eyes can be reduced. Specifically, the single-sided reflector 5 can be slightly tilted downwards to control the propagation and scattering angles of light, adapting to the needs of the driving environment. Furthermore, the semi-transparent mirror can be adjusted and optimized as needed; for example, the angle of the semi-transparent mirror can be changed to control the propagation and scattering angles of light.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
