Description

[Detailed Description of the Invention] The present invention relates to a rear wheel spill prevention device for a large vehicle.

In recent years, with the development of long-distance transportation, large vehicles of this type have become longer and longer, resulting in many accidents in which the rear wheels of small vehicles, such as pedestrians and bicycles, hit pedestrians and bicycles when making left or right turns at intersections. In particular, careful consideration is required when turning left, which creates a blind spot from the driver's seat.

Various proposals have been made to prevent these accidents, and this proposal is one of them.

In other words, the purpose of the present invention is that when a large vehicle such as a truck is turning left or right, when an obstacle such as a pedestrian or bicycle approaches, the object is detected before it makes contact with the vehicle body, and a warning sound is emitted and the vehicle is alerted. The object of the present invention is to provide a device that prevents the obstacle that is about to come into contact with it from being rolled into the rear wheel by removing it to the outside by a rotating buffer.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a rear wheel 1 jamming prevention device A is provided on the left side of a truck body 1 between a front wheel 1a and a rear wheel 1b.

As shown in FIGS. 2 and 3, the rear wheel jamming prevention device A includes a motor 3 mounted on a housing 2, and one end of a support shaft 4a that prevents rotation of the motor 3 via a shaft coupling 5. A buffer body 4 connected to the shaft 3a and whose other end is supported by a bearing 6, a detector 7 attached to one end of the housing 2, and a side lamp 8.
It is equipped with

The buffer body 4 is formed of the support shaft 4a and radial vanes made of an elastic member such as hard rubber and fixed to the support shaft 4a.

The detector 7 has a built-in pair of a projector that emits infrared rays and a receiver that receives the infrared rays reflected by an obstacle. It is connected to the.

When the rear wheel entanglement prevention device A is not needed, it is stored at a predetermined location in the truck body 1 so as not to get in the way.
In order to descend to about 30 crr1 from the ground during use, it is attached to hydraulic, pneumatic, or other known elevating devices (not shown) via support columns 2a, 2a of the casing, and is formed to be able to move up and down with respect to the truck body 1.

On the other hand, to explain the operating state of this device including the block diagram shown in FIG. 4, the motor 3 and the buffer body 4 are
A rotating shock absorber consisting of a warning horn 9, a detector 7, and a lifting device 1
0 is configured to receive power from a power source 13 in conjunction with a direction indicator switch 12 that controls a direction indicator light 11 so as to be activated when the vehicle makes a left turn.

Furthermore, the side lamp 8 is configured to be activated only when both the direction indicator switch 12 and the light switch 14 that controls the headlamp 12 are activated, in order to turn on especially at night to draw attention. Power source 13 is supplied via switch 15 .

Therefore, when a large vehicle equipped with this device approaches an intersection, the direction indicator light 11 flashes and the elevator device 10 moves to the ground 30.
Crrl at a predetermined position 1, and the rotation of the motor 3 causes the shock absorber 4 connected thereto to rotate outward as shown by the solid line arrow. Along the line, infrared rays are emitted as shown by the chain line arrow.

At this time, if an obstacle such as a person or bicycle approaches between the front and rear wheels and blocks the path of the infrared rays, a signal from the receiver that detects the reflected light will sound an alarm 9 such as a buzzer installed in the driver's seat. To notify the driver to take necessary measures to prevent an accident, such as stopping the vehicle, and to prevent the vehicle from being thrown outward and driven into the wheel by a shock absorber 4 having elasticity that rotates even if the vehicle contacts the vehicle. Can be done.

Furthermore, when driving at night, in addition to the above, the side lamps 8 are turned on to visually alert the driver.

In other words, it is possible to inform pedestrians and the like of the presence of the rotating shock absorber 4, and to have the driver check the safety in front of the rear wheels through side mirrors and the like.

Then, when the left turn is completed and the direction indicator switch 12 is reset, the rear wheel 1 thrusting device is restored to its upward position and stops operating.

As described above, the device of the present invention detects pedestrians and bicycles approaching the large vehicle 1 when turning left or right by using the detector 7 consisting of a light emitter that emits light on the outer periphery of the buffer body 4 and a light receiver paired with the light emitter. The driver detects obstacles such as obstacles before they come into contact with the driver, and activates a horn 9 based on the detection signal to alert both the driver and the person approaching, thereby preventing the vehicle from causing harm to the driver.

Further, obstacles that try to come into contact with the vehicle body are elastically pushed outward by the rotating buffer body 4, and can be prevented from being rolled into the rear wheels.

Moreover, these devices are housed on the side of the vehicle body, and are raised and lowered in conjunction with the vehicle's direction indicating means when turning left or right, and operate in the lowered position, so there is no difference from normal driving. Easy to operate.

It should be noted that the present invention is not limited to the above embodiment, and the rear wheel 1
The loading device can be installed on both the left and right sides as desired, and a light beam other than infrared rays or ultrasonic waves can be used as a detector, and the buffer body can be linked via a chino etc. without being directly connected to the motor. Various modifications may be made within the scope of the technical idea set forth in the claims, such as providing a horn on the side of the truck body in addition to the driver's seat to draw attention.
