Abstract

(57) [Summary] [Purpose] An obstacle approach detection device for a vehicle, which gives a warning to the driver as the first step and forcibly brakes the vehicle as the second step depending on the distance between the vehicle and the obstacle. The purpose is to stop. [Construction] An obstacle approach detection device for a vehicle comprises an obstacle approach detection sensor 2, a bell 4 for giving a warning to a driver, a brake 5 forcibly stopping the vehicle, and a switch 6 for canceling these functions. Constitute.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for preventing a vehicle from hitting an obstacle.

[0002]

[Prior art]

 Vehicles, especially those used as playground equipment for children used in amusement parks, etc., have dampers attached to the outer circumference of the vehicle body via springs to prevent damage to the vehicle body in the event of a collision.

[0003]

[Problems to be solved by the device]

 When a car with a damper collides, the car can be prevented from being damaged, but the occupant's shock is large and there is a risk of whiplash.

[0004]

[Means for Solving the Problems]

 In the present invention, a sensor for detecting the approach of an obstacle is attached to a vehicle, the first stage is detected at a distance a from the obstacle, and a warning is given to the driver by a bell or the like, and b (a> When approaching b), brake is forcibly applied and the vehicle is stopped at the position c (b> c). A switch is provided to release these obstacle approach detection functions so that they will not operate.

[0005]

[Action]

 In the obstacle approaching detection device of the present invention configured as described above, the vehicle can be stopped gently before it collides with an obstacle to prevent personal injury and damage to the vehicle, and by canceling its function, It is also possible to operate in a small area such as a repair room.

[0006]

【Example】

 FIG. 1 is an example of a vehicle to which the present invention is applied. FIG. 2 shows an embodiment of the present invention. When the obstacle approach detection sensor 2 mounted on the front surface of the vehicle body 1 approaches the obstacle 3, first, the obstacle detection sensor 2 is actuated at a distance a between the vehicle body 1 and the obstacle. Then, the first-stage detection contact 2a in FIG. 2 is closed to output an output, and the bell 4 is rung to notify the driver and passengers of the approach of obstacles and the possibility of subsequent forced braking. . If the obstacle approaching detection sensor 2 approaches the obstacle with the vehicle body still advancing, the second stage detection contact 2b is closed at the point of the distance b from the obstacle to output, and the electromagnetic brake 5 As a result of urging the vehicle to stop the car urgently, the car stops at the point c before the obstacle. If the driver notices the approach of an obstacle with the first stage bell alarm and applies a brake or operates the steering wheel appropriately, the vehicle can avoid a collision with the obstacle. Also, for vehicles running at or below the rated speed due to the second-stage forced brake, the second-stage detection contact 2b should be operated at a distance b that allows the vehicle to stop before it collides with an obstacle. There is. In a playground vehicle actually used in an amusement park or the like, a is 3 to 5 m, b is 1.5 to 2 m, c is 0.5 to 0.3 m, and the maximum speed of the vehicle is about 10 km / h. For this reason, when the vehicle is put in the garage or the repair room, the obstacle approach detection function interferes with the introduction of the vehicle. In such a case, the sensor release switch 6 should be opened to enable the sensor function. Can be excluded. Reference numeral 7 is a power source for operation, and 8 is a wheel.

[0007]

[Effect of device]

 When the vehicle approaches an obstacle, the alarm and the forced brake are activated in two stages to avoid the collision of the vehicle and the safety of passengers.
