The following specific examples illustrate the implementation of the present invention. Those familiar with the art can easily understand the advantages and effects of the present invention from the content disclosed in this specification.

The structure, ratio, size, etc. shown in the drawings in this specification are only used to match the disclosure content of the specification for the understanding and reading of those familiar with the art, and are not used to limit the implementation of the present invention. Any structural modification, size adjustment, or change in the proportional relationship, without substantial changes to the technical content, shall be regarded as the scope of the present invention.

The vehicle described in each embodiment of this case includes a vehicle body with a plurality of wheels. The gap between the chassis of the vehicle body and the ground is called dangerous height in this case. The dangerous height refers to the height that can accommodate foreign objects under the chassis. The wheel forms an entrapment danger zone in the direction of travel. When a foreign object is between the chassis and the ground and is close to the entrapment danger zone, there is a risk of being engulfed by the wheel. In order to make the description of each embodiment smoother, the wheels mentioned in each example include the front wheels and rear wheels of the vehicle in this example. When the vehicle is moving forward, the involvement in the dangerous area refers to the front of the wheel, and when the vehicle is reversing, the involvement in the dangerous area refers to the rear of the wheel.

In this case, an intelligent anti-roll-in device for a vehicle and the first preferred embodiment of a vehicle with the device. Please refer to Figures 1 to 3 together. The vehicle in this example is illustrated as the bus 10, and the intelligent anti-roll The entry device 15 is installed on the bus 10 running on a fixed route. The intelligent anti-entanglement device 15 for the vehicle is designed according to the height between the bus 10 and the road surface to avoid the vehicle's intelligent anti-entanglement device during driving. The device 15 is damaged by a fixed object on the ground.

Generally, due to the larger wheel size of such large vehicles, there will be a larger gap between the chassis 12 under the vehicle body 11 and the road surface. In the event of a car accident, the greater the height of the gap, it will cause damage to other passers-by. The greater the threat; on the other hand, when the bus 10 is turning, because the vehicle body 11 is longer, the turning radii of the front wheels 13 and the rear wheels 14 are different, so that the running trajectories of the front wheels 13 and the rear wheels 14 will be different. When the wheel 14 turns, an inner wheel difference will occur on the inside, and a larger inner wheel difference usually increases the probability of a traffic accident.

The foreign object in this example is interpreted as a pedestrian standing at a turn at an intersection. When the bus 10 passes through the turn, the inner wheel difference caused by the turn of the bus 10 is likely to make pedestrians negligent. They only notice that the front wheel 13 passes and ignores still standing. In the path range of the rear wheel 14, on the other hand, the driver may not notice the pedestrian due to the blind corner of vision, causing the bus 10 to collide with the pedestrian. If the pedestrian falls in the gap below the vehicle body 11 at this time, when the rear wheel 14 approaches the pedestrian who falls in the gap below, the vehicle intelligent anti-entanglement device 15 provided on the vehicle body 11 can push the pedestrian out of the chassis 12 , To avoid pedestrians being caught by the rear wheel 14 and being run over.

The intelligent anti-rolling device 15 for a vehicle in this example includes a baffle 16 and a safety roller 19. The baffle 16 has a connecting portion 17 and a shielding portion 18. The connecting portion 17 is arranged longitudinally on the chassis 12 on the side of the baffle 16 away from the outer side of the rear wheel 14; the shielding portion 18 is used to shield the dangerous area in front of the rear wheel 14 to prevent pedestrians from directly contacting the rear wheel 14 Involved in run-off. The safety roller 19 is driven by the active unit and pivots along a pivot. The active unit in this example is illustrated as the motor 21. The motor 21 drives the safety roller 19 to rotate through the transmission structure inside the connecting portion 17 and the shielding portion 18; in this example, the pivot The pivoting direction is the side of the safety roller 19 facing the front wheel 13, and the chassis 12 rotates toward the outside of the vehicle body 11. When a pedestrian touches the baffle 16, the safety roller 19 that rotates outward can be used to move the pedestrian from the chassis The involved danger area is pushed to the outside of the chassis.

In addition to pushing the pedestrian away from the bottom of the chassis 12 through the safety roller 19, when the pedestrian hits the shielding portion 18, the shielding portion 18 will pivot from the resting position of Figure 1 to the push of Figure 2 with the connecting portion 17 as the axis. Position, the shielding portion 18 at the pushing position will form an outer inclined surface 22. With the inclination angle of the outer inclined surface 22 and the dual effect of the safety roller 19, pedestrians are pushed out of the bottom of the vehicle body 11, in addition to avoiding being crushed by the rear wheel 14, but also To further avoid pinching people under the vehicle and being pushed and continuously rubbing against the ground.

In this case, an intelligent anti-entanglement device for a vehicle and a second preferred embodiment of a vehicle with the device. Please refer to Figures 4 to 6 together. The vehicle in this example is illustrated as a bus without a fixed route. The intelligent anti-entanglement device used on the bus can be retracted and retracted according to the road conditions of the driving route to avoid the involvement of foreign objects. At the same time, it can also reduce the probability of collision due to being too close to the ground.

Figure 4 is a schematic diagram of the state of the vehicle's intelligent anti-roll-in device being lowered on the front side of the wheels and retracted on the rear side when the bus is traveling; Figure 6 is a schematic diagram of the structure between the vehicle's intelligent anti-entanglement device and the wheels.

Because there are many pedestrians and small cars in the urban area, the bus 40 in this example is driving on an unstable route on urban roads. In order to improve driving safety, as shown in Figure 4, the front wheels 43 and the rear wheels 44 are forcibly lowered. Vehicle intelligent anti-entanglement device 45; On the other hand, as shown in Figure 5, the vehicle intelligent anti-entanglement device 45 behind the rear wheel 44 is only lowered when reversing, which can reversely prevent the bus 40 from accidentally reversing Pedestrians crushed behind the vehicle.

The vehicle intelligent anti-entanglement device 45 in this example includes a baffle 46 and a safety roller 49. The baffle 46 has a connecting portion 47 and a shielding portion 48. The connecting portion 47 is laterally arranged on the chassis 42, and the shielding portion 48 is connected to the connecting portion 47. The horizontal axis is the axis that rotates under the control of the retracting unit 51. When the baffle 46 is rotated and lowered, the shielding portion 48 can cover the dangerous area of the wheel in the direction of travel and rotation; when the baffle 46 is rotated toward the chassis 42, it can prevent the baffle 46 from hitting the fixed objects on the road Damaged. In this example, the active unit is exemplified as the wheel of the bus 40. When the baffle 46 is lowered, the safety roller 49 abuts against the wheel and is driven by the wheel, and rotates in a direction opposite to the rotation of the wheel to prevent foreign objects from being caught in the wheel.

The vehicle body 41 of the bus 40 is provided with a gravity sensor (not shown) to sense the vibration of the shock absorber caused by the drastic changes in the road surface height. When the bus 40 is passing on an uneven road surface, it is installed on the bus 40 The microprocessor (not shown in the figure) will determine whether the sensed signal value is out of the safe range. If the vibration amplitude may cause the road to hit the baffle 46, the microprocessor will drive the retractable unit 51 to correspond to the retractable unit 51 The baffle 46 is folded. Because the human body and road obstacles such as potholes cause vehicle bumps, there are differences. Therefore, if the vehicle's motion state in the height direction changes due to a deceleration hill or bumpy road surface, the motion state caused by pressing the front wheel against the person will be affected. The difference changes. In this way, when the vehicle encounters a pothole, the baffle will be stowed, and the front wheel has been pressed against a person, and the baffle on the front side of the rear wheel will prevent the rear wheel from crushing the accident victim again.

In addition to driving the retractable unit 51 according to the sensing signal of the gravity sensor, the microprocessor can also control the front or rear retractable unit 51 to drive the baffle according to the driving direction of the bus 40, satellite positioning coordinates or manual settings of the driver. 46 Put away or put down. For example, when the satellite positioning coordinate of the bus 40 is an urban area with heavy traffic, the microprocessor will drive the retractable unit 51 on the front side of the wheel, so that the baffle 46 corresponding to the front wheel is also lowered, so as to avoid the traffic of the bus 40 in the urban area. In the accident, people and cars were caught in the front wheels. For another example, when the driver is driving the bus 40 on a rugged mountain road, he can manually set to retract the baffle 46 to prevent the baffle 46 from being damaged by the bumpy mountain road.

The intelligent anti-entanglement device 45 for a vehicle in this example has an airbag 52 arranged on the shielding portion 48. The airbag 52 is made of soft material and filled with gas to buffer the impact of pedestrians hitting the shielding portion 48 and avoid Pedestrians are injured by directly hitting the shielding part 48 made of hard material.

For the third preferred embodiment of this case, please refer to FIGS. 7 to 9 together. The vehicle in this example is illustrated as a truck 70 traveling on a highway and a flat road in an urban area. Generally, pedestrians and small motorcycles are prohibited from using on expressways or highways due to legal restrictions. As a result, based on the fact that foreign objects are unlikely to be caught in the wheels, when the truck 70 is traveling faster than the minimum speed limit, the car The intelligent anti-entanglement device 75 will be stored upward to avoid a large amount of wind resistance; if the truck 70 is driving on the highway and a traffic accident occurs in front, when the driver slams on the brakes, the intelligent anti-entanglement device on the front of the front wheel 73 and the rear wheel 74 75 will be released downwards to prevent falling objects in front of the accident or people injured in a car accident from getting involved in the dangerous area of the wheel.

The vehicle intelligent anti-entanglement device 75 in this example includes a baffle 76 and a safety roller 79. The baffle 76 has a connecting portion 77 and a shielding portion 78. The connecting portion 77 is longitudinally arranged on the chassis 72, and the connecting portion 77 is far from the end of the chassis 72. It is connected under the shielding part 78. When the vehicle intelligent anti-entanglement device 75 is stowed upwards, the retractable unit (not shown) will pull up the connecting part 77. At this time, the shielding part 78 will fold upwards and store it horizontally. Below the chassis 72. The shielding portion 78 is formed with an outer inclined surface 80 on the side opposite to the wheel. The outer inclined surface 80 is inclined from the center of the chassis 72 toward the outer side of the wheel. When a falling object or a person hits the shielding portion 78, it will be guided by the outer inclined surface 80. Lead out the range below the chassis 72 to avoid getting involved in the dangerous area of the wheel.

In this example, the active unit is illustrated as the front wheel 73 and the rear wheel 74 of the truck. The safety roller 79 is rotatably connected to the connecting portion 77. When the baffle 76 is released downward, the safety roller 79 and the baffle 76 are released simultaneously And driven by the wheel through the belt 81, the safety roller 79 rotates in a direction opposite to the rotation direction of the wheel, and pushes foreign objects away from the dangerous area.

The vehicle body 71 of the truck 70 is provided with, for example, an optical distance sensor 82, which can sense the distance between the vehicle body 71 and the road surface, and transmit the sensing signal to the microprocessor of the truck 70. The microprocessor will depend on the road surface The condition drives the retractable unit to retract or release the baffle 76 corresponding to the retractable unit. For example, when the truck 70 travels on a flat road in the urban area and passes through a section of the deceleration hill, in order to prevent the chassis 72 from lowering when the truck 70 passes the deceleration hill, causing the baffle 76 or the safety roller 79 to hit the deceleration hill, the microprocessor After receiving the sensing signal of the distance change, the retractable unit in front of the wheel is driven to retract the baffle 76 corresponding to the retractable unit.

The microprocessor in this case can control the retracting of the baffle according to the distance between the vehicle body and the road, the speed of the vehicle, or whether the vehicle is suddenly braked; on the other hand, it can also control the retracting of the baffle according to the driving direction of the vehicle, satellite positioning coordinates or manual settings. put. In addition to using the microprocessor to control the retracting and retracting of the baffle, the intelligent anti-entanglement device for the car in this case can also be set to release the baffle downward by default when the vehicle is in an unpowered state to prevent the vehicle from stopping. The slope, because of the brake failure, suddenly dropped down and hurt people.

In summary, in this case, an intelligent anti-entanglement device for a vehicle and a vehicle equipped with the device can push foreign objects away from under the chassis or get involved in a dangerous area by means of a safety roller, thereby reducing damage caused by a car accident. In addition to the structure of the safety roller described above, the outer slope formed by the shielding portion can also use the inclination angle of the outer slope to push foreign objects out of the bottom of the vehicle. In addition, the baffle and safety roller in this case can be retracted and retracted according to the vehicle's power state and driving conditions to prevent the baffle and safety roller from being hit and damaged by road fixtures; on the other hand, with the retractable structure of the baffle and safety roller, The intelligent anti-entanglement device for vehicles can have a relatively close distance to the ground, effectively blocking foreign objects from approaching and entangled in the dangerous area, and being caught by the wheels and causing injuries to people and vehicles.

However, the above are only preferred embodiments of the present invention and cannot be used to limit the scope of the present invention. Especially, the present invention is not limited to large buses or trucks. Even if it is installed on a small vehicle, it can still be used. It greatly reduces the safety risk of accidentally crushing people and even pets. Therefore, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification should still fall within the scope of the present invention. After the description of the preferred embodiments of the present invention, those familiar with this technical field should be able to understand that this case is indeed a novel, progressive, and industrially applicable invention with deep development value.
