It concentrates on the use of computers, modern sensors, information fusion, communications, artificial intelligence and automatic control technologies, and is a typical high-tech complex.
[0003] At present, the existing smart cars are generally small cars, and no corresponding collision avoidance devices are installed when they leave the factory, which results in the inability to help the vehicle avoid collisions while driving and reduce the possibility of accidents. In the event of a collision, the impact force cannot be effectively buffered, increasing the damage caused by the collision to the vehicle, and also increasing the damage caused by the collision to the driver. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the vehicle cannot be helped to avoid collision, reduce the possibility of accidents, cannot effectively buffer the impact force, increase the damage caused by the collision to the vehicle, and increase the harm caused by the collision to people, and to propose an intelligent collision avoidance device.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] An intelligent collision avoidance device, comprising:
[0007] A guard bar, a guard cover is fixedly provided on the front side of the guard bar, a guard plate is slidably provided inside the guard cover, two distance measuring sensors are symmetrically fixedly provided on both sides of the guard bar and the front side of the guard plate, sound and light alarms are fixedly provided on both sides of the guard bar, the sound and light alarms are connected with the distance measuring sensor signals for communication, and a mounting plate is fixedly provided on the rear side of the guard bar;
[0008] A first buffer assembly, the first buffer assembly is arranged between the bumper and the guard plate and is used to buffer the impact force;
[0009] The second buffer component is arranged between the guard bar and the protective plate and is used for buffering the impact force.
[0010] In a possible design, the first buffer assembly includes four dampers fixedly arranged in a rectangular shape on the front side of the bumper, the piston ends of the four dampers are fixedly connected to the rear side of the protective plate, the outside of the four dampers are each provided with a buffer spring, one end of the buffer spring is fixedly connected to the front side of the bumper, and the other end of the buffer spring is fixedly connected to the rear side of the protective plate.
[0011] In a possible design, the second buffer assembly includes fixing frames which are respectively fixed longitudinally on the sides of the guard bar and the protective plate close to each other, and a slide groove is provided on the sides of the two symmetrical fixing frames close to each other, and two slide grooves are provided inside each of the fixing frames, and a slide rod is fixedly provided inside each slide groove, and sliders are slidably provided on the outside of multiple slide rods, and the sliders are slidably provided in the slide groove, and return springs are fixedly provided on both sides of each slider, and the ends of the two return springs fixed to each slider are respectively fixedly connected to the two sides of the inner wall of the fixing frame slide groove, and two cross-hinged connecting rods are provided between the two symmetrical fixing frames, and the ends of the two connecting rods located on the same side are respectively movably connected to the two symmetrical sliders.
[0012] In a possible design, a rubber pad is fixedly provided on the front side of the protective plate.
[0013] In one possible design, a reflective warning sticker is provided on the front side of the rubber pad.
[0014] In a possible design, the bumper, the protective plate and the rubber pad are all provided with a plurality of evenly distributed through holes.
[0015] In the present application, when the device is used at the beginning, the device is installed on the front and rear sides of the vehicle through the guard bar and the mounting plate. During the driving of the vehicle, the distance sensor monitors the road section and oncoming vehicles during the driving process. When oncoming vehicles or obstacles on the road approach the vehicle, the distance sensor will transmit signals to the sound and light alarm and the vehicle's internal alarm system. The vehicle's internal alarm system will sound an alarm to remind the driver, thereby facilitating the driver to make timely response and avoidance. The sound and light alarm will emit an alarm sound and flash to warn oncoming vehicles, thereby enabling drivers in oncoming vehicles to make timely response and avoidance. When the front or rear end of the vehicle is hit, the guard plate bears the force from the impact, and the rubber pad on it first preliminarily buffers the impact force to reduce the impact force, and then the impacted guard plate disperses the impact force to the damper and the fixing frame. The impact force is dispersed When the vehicle is on the damper, the damper slows down the movement of the guard plate through internal friction or resistance, and then buffers the impact through the elastic principle of the buffer spring. When the impact force is dispersed to the fixed frame, the guard plate pushes the fixed frame to move to one side of the guard bar. When the fixed frame moves, it pushes the two intersecting connecting rods, so that the two connecting rods are forced to move toward each other. When the connecting rod moves, it drives the sliders at both ends to slide on the sliding rods in the sliding groove of the fixed frame. When the slider slides, the return spring on one side of the slider is compressed and buffers the force through its elastic principle. The return spring on the other side of the slider pulls the slider and forms a pulling resistance to the movement of the slider through its elastic principle, thereby controlling and reducing the moving range of the slider, thereby buffering the force received by the guard plate, thereby reducing the loss caused to the vehicle by the collision, and also reducing the damage caused to the driver by the collision.
[0016] The utility model has the following beneficial effects:
[0017] The utility model can simultaneously give an alarm to the driver of the vehicle and the drivers of oncoming vehicles by setting the distance measuring sensor and the sound and light alarm. During the driving process of the vehicle, the distance measuring sensor monitors the road section and oncoming vehicles during the driving process. When the oncoming vehicles or obstacles on the road approach the vehicle, the distance measuring sensor transmits a signal to the sound and light alarm and the internal alarm system of the vehicle. The internal alarm system of the vehicle will send an alarm to remind the driver, so that it is convenient for the driver to make timely response and avoidance. The sound and light alarm will send an alarm sound and flash to warn the oncoming vehicles, so that the drivers of the oncoming vehicles can make timely response and avoidance, which can help vehicles avoid collisions and reduce the possibility of accidents.
[0018] In the utility model, by setting the first buffer component, when the front end or rear end of the vehicle is hit, the impacted guard plate disperses the impact force to the damper and the fixing frame. When the impact force is dispersed to the damper, the damper slows down the movement of the guard plate through internal friction or resistance, and then buffers the impact through the elastic principle of the buffer spring, thereby reducing the damage caused by the collision to the vehicle, and also reducing the damage caused by the collision to the driver;
[0019] The utility model discloses a second buffer assembly, when the impact force is dispersed to the fixed frame, the protective plate pushes the fixed frame to move toward one side of the guard bar, and when the fixed frame moves, the two intersecting connecting rods are pushed, so that the two connecting rods are forced to move toward the side close to each other, and when the connecting rod moves, the sliders at both ends thereof are driven to slide on the sliding rods in the sliding grooves of the fixed frame, and when the slider slides, the return spring on one side of the slider is compressed by the force, and the force received is buffered by its elastic principle, and the return spring on the other side of the slider pulls the slider, and forms a pulling resistance to the movement of the slider by its elastic principle, so as to control and reduce the movement range of the slider, so as to buffer the force received by the protective plate, thereby reducing the loss caused by the collision to the vehicle, and also reducing the damage caused by the collision to the driver;

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0027] Example 1
[0028] Reference Figure 1-4 , a collision avoidance device, comprising:
[0029] A guard bar 1, a guard cover 2 is fixedly provided on the front side of the guard bar 1, a guard plate 3 is slidably provided inside the guard cover 2, two distance measuring sensors 4 are symmetrically fixedly provided on both sides of the guard bar 1 and the front side of the guard plate 3, sound and light alarms 5 are fixedly provided on both sides of the guard bar 1, and the sound and light alarms 5 are connected with the distance measuring sensors 4 for signal communication, and a mounting plate 6 is fixedly provided on the rear side of the guard bar 1;
[0030] A first buffer assembly, which is disposed between the bumper 1 and the guard plate 3 and is used to buffer the impact force;
[0031] The second buffer component is arranged between the bumper 1 and the protective plate 3 and is used to buffer the impact force.
[0032] The above technical solution can achieve the goal of buffering the impact received through the setting of the first buffer component, and the damper 7 and the buffer spring 8 can be used to buffer the impact, thereby reducing the damage caused by the collision to the vehicle, and also reducing the damage caused by the collision to the driver. Through the setting of the second buffer component, the compression and pulling of the return spring 12 can reduce and buffer the movement range of the slider 11 and the folding of the connecting rod 13, so as to buffer the force applied to the protective plate 3, thereby reducing the damage caused by the collision to the vehicle, and also reducing the damage caused by the collision to the driver. The setting of the distance sensor 4 (brand model: Panasonic / HG-C1030) and the sound and light alarm 5 (brand model: Gulf / HX-320B) can help the vehicle avoid collision and reduce the possibility of accidents. The distance sensor 4 is connected to the vehicle's internal alarm system signal communication.
[0033] Reference Figure 3 The first buffer assembly includes four dampers 7 fixedly arranged in a rectangular shape on the front side of the guard bar 1, the piston ends of the four dampers 7 are fixedly connected to the rear side of the protective plate 3, and the outside of the four dampers 7 is provided with a buffer spring 8, one end of the buffer spring 8 is fixedly connected to the front side of the guard bar 1, and the other end of the buffer spring 8 is fixedly connected to the rear side of the protective plate 3.
[0034] The above technical solution can achieve the goal of arranging the damper 7 and the buffer spring 8. When the front or rear end of the vehicle is hit, the impacted protective plate 3 will disperse the impact force to the damper 7 and the fixing frame 9. When the impact force is dispersed to the damper 7, the damper 7 slows down the movement of the protective plate 3 through internal friction or resistance, and then buffers the impact through the elastic principle of the buffer spring 8, thereby reducing the damage caused to the vehicle by the collision, and also reducing the damage caused to the driver by the collision.
[0035] Reference Figure 4 The second buffer assembly includes a fixing frame 9 which is respectively fixed longitudinally on the side where the guard bar 1 and the protective plate 3 are close to each other. A slide groove is provided on the side where the two symmetrical fixing frames 9 are close to each other. Two slide grooves are provided inside each fixing frame 9. A slide rod 10 is fixed inside each slide groove. Slide blocks 11 are slidably provided outside the multiple slide rods 10. The slide blocks 11 are slidably provided in the slide grooves. Reset springs 12 are fixedly provided on both sides of each slide groove. The ends of the two reset springs 12 fixed to each slide groove 11 are fixedly connected to the inner walls of the slide grooves of the fixing frames 9 respectively. Two cross-hinged connecting rods 13 are provided between the two symmetrical fixing frames 9. The ends of the two connecting rods 13 located on the same side are movably connected to the two symmetrical slide blocks 11 respectively.
[0036] The above technical scheme can achieve the following goal through the setting of the protective plate 3, the fixing frame 9, the sliding bar 10, the slider 11 and the connecting rod 13. When the impact force is dispersed to the fixing frame 9, the protective plate 3 pushes the fixing frame 9 to move to one side of the guard bar 1. When the fixing frame 9 moves, the two intersecting connecting rods 13 are pushed, so that the two connecting rods 13 are forced to move toward the side close to each other. When the connecting rod 13 moves, it drives the sliders 11 at both ends to slide on the sliding bar 10 in the sliding groove of the fixing frame 9. When the slider 11 slides, the return spring 12 on one side of the slider 11 is compressed by force, and the force received is buffered by its elastic principle. The return spring 12 on the other side of the slider 11 pulls the slider 11, and forms a pulling resistance to the movement of the slider 11 by its elastic principle, thereby controlling and reducing the moving range of the slider 11, thereby buffering the force received by the protective plate 3, thereby reducing the loss caused by the collision to the vehicle, and also reducing the damage caused by the collision to the driver.
[0037] The present application can be used in the technical field of intelligent collision avoidance devices for vehicles, and can also be used in other fields applicable to the present application.

[0040] The above technical solution can achieve the goal of setting the rubber pad 15. When the front or rear end of the vehicle is hit, the protective plate 3 is subjected to the force from the collision. The rubber pad 15 thereon firstly buffers the impact force of the collision, thereby reducing the dissipation of the impact force.
[0041] Reference Figure 1 A reflective warning sticker 16 is provided on the front side of the rubber pad 15 .
[0042] The above technical solution can achieve the goal of providing the reflective warning sticker 16 to remind the oncoming vehicles in front and the vehicles behind when driving in poor light or at night, so that the drivers of other vehicles can clearly know the existence of danger and make timely braking or avoidance.
[0043] Reference Figure 1-3 The bumper 1, the protective plate 3 and the rubber pad 15 are all provided with a plurality of evenly distributed through holes 14.
[0044] The above technical solution can achieve the goal of providing multiple evenly distributed through holes 14 on the bumper 1, the protective plate 3 and the rubber pad 15, so that the collision avoidance device does not affect the normal heat dissipation of the vehicle when installed at the front end of the vehicle, thereby making the device more practical.
[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the ranging sensor 4, the sound and light alarm 5 and the damper 7 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
