Description

Technical Field

[0001] The present invention relates to a vehicle slip prevention device that prevents slipping of vehicle tires by spreading an anti-slip substance on a frozen road surface.

Background Art

[0002] Currently, as a method for preventing slipping of a running vehicle, there is an ABS (Anti-lock Braking System). This is an effective means when a certain amount of frictional force can be ensured on a snow-packed road surface or the like. However, on a frozen road surface, the frictional force extremely decreases, and the ABS is not satisfactory. Therefore, at places where there is a risk of being stuck due to slipping at intersections, mountain passes, etc., a method has been adopted in which a sandbox is installed at the roadside and a person gets out of the vehicle and spreads sand on the road.

[0003] On the other hand, several decades ago, as a representative measure for preventing slipping on a road surface frozen by snow accumulation in winter, there were studded tires. However, it has been prohibited from use because it scrapes the road surface during driving on a paved road surface and causes dust pollution. Since then, studless tires have become popular and are used by many drivers. However, many people have experienced the scary feeling that the braking distance is long on a frozen road surface and they cannot stop even if they want to. Under such circumstances, a slip prevention method that can stop safely has been desired. As a means for effectively preventing slipping even on such a frozen road, "Vehicle Slip Prevention Device" disclosed in Patent Document 1, Japanese Patent Application Laid-Open No. 2006-188077, is known.

Embodiments for Carrying Out the Invention

[0026] The device of the present invention consists of a main body 1, a spraying nozzle 2, a control box 4, control wiring 5, and an operation switch 6 as shown in Figure 2. By operating the operation switch 6 inside the vehicle, an anti-slip substance 3 can be ejected from the tip of the spraying nozzle 2 to make the frozen road surface 12 less slippery.

[0027] In Figure 2, the main body 1 attached near the bumper 13 operates by the operation switch 6 attached near the driver's seat. When the operation switch 6 is turned on, the main body 1 operates via the control box 4 and the control wiring 5, and the anti-slip substance 3 is ejected onto the frozen road surface 12 in front of the tire 11 of the vehicle 10.

[0028] Figure 3 shows the main body of the anti-slip device of the present invention. It is composed of a tank 1·1, 3 containing the anti-slip substance 3, a screw 1·2 for transporting it downward, a blower (with a built-in motor) 1·3 for further ejecting the transported anti-slip substance 3 forward by the wind, a rectifying port 1·4 for straightening the ejected flow, a stirring fan 1·5 for preventing the bridging of the substance 3, and a motor 1·6 for rotating the screw 1·2.

[0029] In Figure 3, when the operation switch 6 near the driver's seat is turned on, the motor 1·6 at the upper part of the main body 1 rotates, causing the screw 1·2 connected to the output shaft of the motor 1·6 to rotate and transport the anti-slip substance 3 downward. Then, it is ejected onto the frozen road surface 12 (refer to Figure 2) through the rectifying port 1·4 by the blower 1·3 for transportation below the main body 1. Incidentally, the anti-slip substance 3 in the tank 1·1 is prevented from forming a bridge where the anti-slip substance 3 accumulates by the stirring fan 1·5 fixed to the output shaft of the motor 1·6 in the same way as the screw 1·2.

[0030] Figure 4 shows the state where the main body 1 is mounted on the upper part of the bumper 13 of the vehicle 10. It is clamped by the outer mounting bracket 20 and the inner mounting bracket 21 attached to the front grille 14 of the vehicle 10 and fixed with the fixing screw 22. The main body 1 is also fixed to the mounting bracket 20 by the wing nut 23. At this time, if the outer mounting bracket 23 protrudes from the bumper 13, it is adjusted to dimensions that can meet the vehicle inspection standards.

[0031] Furthermore, although it is conceivable that the mounting state of the main body 1 may protrude beyond the bumper 13, since it is a simple mounting using the wing nut 23, it meets the vehicle inspection standards.

[0032] FIG. 5 shows a state in which the main body 1 is mounted on the upper part of the bumper 13 of the vehicle 10. One unit is mounted on each side of the vehicle, and the anti-slip substance 3 is ejected in front of the tires 11 of the vehicle 10, respectively.

[0033] FIG. 6 shows a state in which the main body 1 is mounted in the engine room 15 of the vehicle 10. From the engine room 15, the anti-slip substance 3 is ejected in front of the tire 11 or onto the outer periphery of the tire 11 by the ejection nozzle 2.

[0034] FIG. 7 shows a state in which the main body 1 is mounted on the upper part of the front fender 16 of the vehicle 10. From the front fender 16, the anti-slip substance 3 is ejected in front of the tire 11 or onto the outer periphery of the tire 11 by the ejection nozzle 2.

[0035] FIG. 8 shows a state in which the main body 1 is mounted in front of and behind the light truck 50. The anti-slip substance 3 is ejected in front of the front tire 51 or in front of the rear tire 52.

[0036] FIG. 9 shows a state in which the main body 1 is mounted in front of and behind the 2-ton truck 60. The anti-slip substance 3 is ejected in front of the front tire 61 or in front of the rear tire 62.

[0037] FIG. 10 shows a state diagram of the main body 70 with the enlarged tank 1·1. As shown in FIGS. 8 and 9, when there is a wide mounting space near the front of the rear wheels of the light truck 50 or the 2-ton truck 60, by mounting the main body 70 with the enlarged tank 1·1, the capacity of the anti-slip substance can be increased.

[0038] FIG. 11 shows an image diagram of the main body 70 with the enlarged tank 1·1 attached to the light truck 50.

[0039] FIG. 12 shows an image diagram of the main body 70 with the enlarged tank 1·1 attached to the 2-ton truck 60.

[0040] Figure 13 shows the image diagram of Claim 3. The anti-slip substance 3 in the tank 1·1 is conveyed downward without being bridged by the stirring fan 1·5. Then, it is further conveyed downward by the rotation of the motor 31 that drives the rotary valve 30, and is conveyed to the rectifying port 1·4 by the blower 1·3. This rotary valve 30 can not only control the supply and stop of the anti-slip substance 3, but also adjust the ejection amount by changing the rotation speed.

[0041] Figure 14 shows the image diagram of Claim 4. The anti-slip substance 3 in the tank 1·1 is conveyed downward by the vibrator 40. Then, it is conveyed to the rectifying port 1·4 by the blower 1·3.

[0042] Figure 15 shows the image diagram of the compressed air type. The anti-slip substance 3 in the tank 82 is ejected from the ejection nozzle 84 when the solenoid valve 83 opens by the compressed air 85 stored in the air tank 81. The ejection amount of the anti-slip substance 3 can be controlled by the regulator 86 that controls the opening and closing time and the supply pressure of this solenoid valve 83.
